the sum of 4500 is divided among A,S,J s received 1/2 A reeived $1050 and j received the remainder calculate s shared J shared the ratio in which the money was shared percentage of the total that A received
S received $1050, J received $0, and the ratio of the money shared between S and J is 0:1. A received 23.33% of the total amount.
Step 1: Determine the amount A received.
We know that A received 1/2 of the total amount, which is $1050. Therefore, the total amount can be calculated by multiplying A's portion by 2: 1050 * 2 = $2100.
Step 2: Calculate the amount J received.
To find the amount J received, we need to subtract A's and S's amounts from the total.
From Step 1, we know that the total is $2100. S received the same amount as A, which is $1050.
Therefore, we subtract A's and S's amounts from the total: 2100 - 1050 - 1050 = $0.
Since J received the remainder, we see that J did not receive any amount from the initial sum of $4500.
Step 3: Calculate the amount S received.
To find the amount S received, we need to subtract S's amount from the total.
Again, from Step 1, we know that the total is $2100. S received the same amount as A, which is $1050.
Therefore, we subtract S's amount from the total: 2100 - 1050 = $1050.
Step 4: Calculate the ratio in which the money was shared between S and J.
Since J did not receive any amount, the ratio of the money shared between S and J is 0:1.
Step 5: Calculate the percentage of the total amount that A received.
To find the percentage, we divide A's amount by the total and multiply by 100: (1050/4500) * 100 = 23.33%.
Therefore, S received $1050, J received $0, and the ratio of the money shared between S and J is 0:1.
A received 23.33% of the total amount.

A chemistry lab requires students to identify chemical compoinds by using various tests. Each student is given samples of 3 different compounds labeled A, B, and C. Each student is also given a list of 12 possible compounds. If a student does not perform the tests and randomly chooses 3 from the list, what is the probability that she guesses all three correctly?
The probability that the student guesses all three compounds correctly is 1/1320.
To calculate the probability that the student guesses all three compounds correctly, we need to determine the number of favorable outcomes (correct guesses) and the total number of possible outcomes (all possible combinations).
Given that the student randomly chooses 3 compounds from a list of 12 possible compounds, the total number of possible outcomes is the number of ways to choose 3 compounds out of 12, which can be calculated using the combination formula:
Total number of possible outcomes = C(12, 3) = 12! / (3!(12-3)!) = 220
Now, let's consider the favorable outcomes, which are the cases where the student guesses all three compounds correctly. Since the student has no prior knowledge of the compounds, the probability of guessing each compound correctly is 1 out of 12.
For the first guess, there is a 1/12 probability of choosing the correct compound. Similarly, for the second guess, there is a 1/11 probability of choosing the correct compound (as one compound has already been chosen). Finally, for the third guess, there is a 1/10 probability of choosing the correct compound (as two compounds have already been chosen).
To find the probability of all three correct guesses, we multiply the probabilities of each independent event:
Probability of all three correct guesses = (1/12) * (1/11) * (1/10) = 1/1320

Find x. Round your answer to the nearest tenth of a degree.
[tex]\tan(x )=\cfrac{\stackrel{opposite}{18}}{\underset{adjacent}{11}} \implies \tan^{-1}(~~\tan( x )~~) =\tan^{-1}\left( \cfrac{18}{11} \right) \\\\\\ x =\tan^{-1}\left( \cfrac{18}{11} \right)\implies x \approx 58.6^o[/tex]
Make sure your calculator is in Degree mode.
Answer:
x = 58.6°
Step-by-step explanation:
Because this is a right triangle, we're able to find the measure of angle x using one of the trigonometric ratios.
When angle x is the reference angle, the side that is 18 units long is the opposite side and the side that is 11 units long is the adjacent side.
Thus, we can use the tangent ratio, which is given by:
tan (θ) = opposite / adjacent, where
θ is measure of the reference angleThus, we have tan (θ) = 18 / 11
In order to find angle measures we use inverse trigonometry:
tan^-1 (18 / 11) = x
58.57043439 = x
58.6 = x
Thus, the measure of angle x is about 58.6°

The concept of joint probability is utilized in probability theory, a statistical tool that investigates the probability of two events happening simultaneously. It is an estimation of the probability of two or more events occurring simultaneously. Joint probability is a method of defining the probability of two events happening at the same time.The joint probability of two statistical dependent events Y and Z can be written as P(Y and Z) = P(Y) * P(Z|Y).This implies that the possibility of Z happening given Y has happened multiplied by the probability of Y happening is the joint probability of Y and Z. P(Z|Y) refers to the probability of Z occurring when Y is true or has already occurred. It is conditional probability and is often used to calculate joint probabilities.The formula for conditional probability is P(A|B) = P(A and B)/P(B), which can be simplified to P(A and B) = P(A|B) * P(B). This formula is applicable to P(Y and Z), where P(Y and Z) = P(Z|Y) * P(Y).

how do i simplify 2i^68 and show steps
The simplified form of 2i^68 is the value of 2^34.
To simplify 2i^68, we need to use the properties of imaginary numbers and the exponent rules. Here are the steps to simplify it:
Recall that i is defined as the square root of -1.
Since i^2 equals -1, we can rewrite the expression as (2i^2)^34.
Simplify the exponent by applying the rule that (a^m)^n equals a^(mn). In this case, we have (2i^2)^34 = 2^34 * (i^2)^34 = 2^34 * i^(234).
Simplify the terms. 2^34 is a large number, but we can still calculate it. i^(2*34) can be further simplified as i^68.
Determine the value of i^68 by noting that i follows a pattern: i^1 = i, i^2 = -1, i^3 = -i, i^4 = 1. The pattern repeats every four powers of i.
Since 68 is divisible by 4, i^68 equals 1.
Plug in the simplified values: 2^34 * i^(2*34) = 2^34 * i^68 = 2^34 * 1 = 2^34.

The percent increase in enrollment from 1980 to 2004 is 125%.
To calculate the percent increase in enrollment from 1980 to 2004, we can use the following formula:
Percent Increase = ((Final Value - Initial Value) / Initial Value) * 100
Given that the number of students in 1980 was 4,000 and the number of students in 2004 was 9,000, we can substitute these values into the formula:
Percent Increase = ((9,000 - 4,000) / 4,000) * 100
Simplifying the numerator:
Percent Increase = (5,000 / 4,000) * 100
Performing the division:
Percent Increase = 1.25 * 100
Calculating the final result:
Percent Increase = 125%
Therefore, the percent increase in enrollment from 1980 to 2004 is 125%.
This means that the number of students increased by 125% over the 24-year period. In other words, the enrollment more than doubled during this time frame.

Answer:
the amount of metal required to make the can is 352.8π square centimeters.
Step-by-step explanation:
To calculate the amount of metal required to make the can, we need to find the surface area of the can.
The can consists of two circular ends (top and bottom) and a cylindrical body.
1. Surface Area of the Circular Ends:
The circular ends can be considered as two circles. The surface area of each circular end can be calculated using the formula for the area of a circle:
A_end = πr^2
Given the diameter of the can is 14 cm, the radius (r) is half the diameter, so r = 14 cm / 2 = 7 cm.
A_end = π * 7^2 = 49π cm^2 (for each circular end)
2. Surface Area of the Cylindrical Body:
The cylindrical body of the can can be represented as a rectangle that is rolled into a cylinder. The surface area of the cylindrical body can be calculated using the formula for the lateral surface area of a cylinder:
A_body = 2πrh
Given the height (h) of the can is 18.2 cm and the radius (r) is 7 cm, we can calculate the surface area of the cylindrical body:
A_body = 2π * 7 * 18.2 = 254.8π cm^2
3. Total Surface Area:
To calculate the total surface area of the can, we add the surface areas of the circular ends and the cylindrical body:
Total Surface Area = 2 * A_end + A_body
= 2 * 49π + 254.8π
= 98π + 254.8π
= 352.8π cm^2
Therefore, the amount of metal required to make the can is 352.8π square centimeters.
Which equation can pair with x + 2y = 5 to create an inconsistent system?
Answer:The equation that can be paired with x + 2y = 5 to create an inconsistent system is given by:
2x + 4y = 3.
Step-by-step explanation:
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
An inconsistent system is a system that has no solutions, and it happens when the coefficients of x and y are multiples, and the independent terms are not.
Hence:
x + 2y = 5.
2x + 4y = 3.
Is inconsistent, as the variables are each multiplied by 2, but the independent term is not.

K (Present value of a growing perpetuity) Your firm has taken on cost saving measures that will provide a benefit of $16,000 in the first year. These cost savings will decrease each year at a rate of 3 percent forever. If the appropriate interest rate is 8 percent, what is the present value of these savings? The present value of these cost savings is S (Round to the nearest cent.)
To calculate the present value of the cost savings, we can use the formula for the present value of a growing perpetuity. The formula is:
K = C / (r - g)
Where:
K = Present value of the growing perpetuity
C = Cash flow in the first year
r = Interest rate
g = Growth rate
In this case, C = $16,000, r = 8% (or 0.08), and g = -3% (or -0.03). We use a negative sign for the growth rate since the cost savings are decreasing each year.
Now we can substitute the values into the formula and calculate the present value:
K = 16000 / (0.08 - (-0.03))
K = 16000 / 0.11
K ≈ $145,454.55
Therefore, the present value of these cost savings is approximately $145,454.55.

Which table could be used to graph a piece of the function?
An x-y coordinate table is the appropriate table to use when graphing a piece of a function. This table helps you to determine the corresponding y-values for different x-values and plot the points on a graph.
To graph a piece of a function, you would typically use an x-y coordinate table, also known as a Cartesian coordinate system. This table consists of two columns: one for the x-values (also called the input values) and one for the corresponding y-values (also called the output values). Each row in the table represents a point on the graph.
To graph a piece of a function, you would need to identify the domain (the set of possible x-values) for that specific piece. Once you have the domain, you can choose values from that domain and calculate the corresponding y-values using the function.
For example, if you have a piece of a linear function, such as y = 2x + 3, you could create a table by choosing various x-values and calculating the corresponding y-values. Let's say we choose x-values of -2, 0, and 2. Plugging these values into the equation, we find the corresponding y-values: -1, 3, and 7.
So the table for this piece of the linear function would look like this:
x | y
--------------
-2 | -1
0 | 3
2 | 7
Once you have the x-y coordinate table, you can plot the points on a graph and connect them to create the graph of the piece of the function.

A spherical balloon has a radius of 165 mm. How much air was used to fill this balloon?
Step-by-step explanation:
To calculate the amount of air used to fill a spherical balloon, we need to determine its volume. The volume of a sphere can be calculated using the formula:
Volume = (4/3) × π × radius³
Given that the radius of the balloon is 165 mm, we can substitute this value into the formula:
Volume = (4/3) × π × (165 mm)³
Now, let's calculate the volume of the balloon:
Volume = (4/3) × 3.14159 × (165 mm)³
Volume ≈ 4.18879 × (165 mm)³
Evaluating this expression will give us the volume of the balloon in cubic millimeters. However, to express it in a more practical unit, such as liters, we need to convert the volume from cubic millimeters to liters.
1 liter = 1000 cubic centimeters (cc)
1 cubic centimeter (cc) = 1 milliliter (ml)
1 milliliter (ml) = 1 cubic millimeter (mm³)
To convert the volume from cubic millimeters to liters, we divide the volume by 1000:
Volume (liters) = Volume (cubic millimeters) / 1000
So, let's calculate the volume of the balloon in liters:
Volume (liters) = (4.18879 × (165 mm)³) / 1000
Using a calculator to evaluate this expression, we find:
Volume (liters) ≈ 7.976 liters
Therefore, approximately 7.976 liters of air were used to fill the spherical balloon.

(8x + 6)/(- x ^ 2 + 1)
(4x - 8)/(- 2x ^ 2)
The rational expression that is undefined when x = 0 is (8x + 6)/(-x^2 + 1).
To determine which rational expression is undefined when x = 0, we need to find the values of x that make the denominator equal to zero. When the denominator of a rational expression is zero, the expression is undefined because division by zero is not possible.
Let's analyze each of the given expressions:
(5x^2 - 4)/(3x - 3):
To check if this expression is undefined when x = 0, we substitute x = 0 into the denominator:
3(0) - 3 = -3
Since the denominator is not zero, this expression is defined when x = 0.
(6x^2)/(9x - 3):
Similarly, we substitute x = 0 into the denominator:
9(0) - 3 = -3
Again, the denominator is not zero, so this expression is defined when x = 0.
(8x + 6)/(-x^2 + 1):
For this expression, we substitute x = 0 into the denominator:
-(0)^2 + 1 = -0 + 1 = 1
The denominator is not zero, indicating that this expression is defined when x = 0.
(4x - 8)/(-2x^2):
When we substitute x = 0 into the denominator:
-2(0)^2 = -2(0) = 0
The denominator becomes zero when x = 0. Therefore, this expression is undefined when x = 0.

Annette has 3 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 9mph and walks back at a speed of 3mph , how long should she plan to spend walking back?
Answer:
Annette should plan to spend 2.25 hours walking back.
Step-by-step explanation:
To solve this problem, we can use the formula:
Time = Distance / Speed
Let's assume the distance of the race is D miles.
Annette spends her time running the distance of the race, which takes:
Time running = D / 9 hours
She then walks back the same distance, which we need to find the time for:
Time walking = D / 3 hours
Since Annette has a total of 3 hours for her training, the sum of the running time and walking time should equal 3 hours:
D / 9 + D / 3 = 3
To simplify the equation, we can multiply all terms by 9 to eliminate the denominators:
D + 3D = 27
Combining like terms:
4D = 27
Dividing both sides of the equation by 4:
D = 6.75
So, the distance of the race is 6.75 miles.
To find the time Annette should spend walking back, we substitute the distance into the time-walking formula:
Time walking = D / 3 = 6.75 / 3 = 2.25 hours
Therefore, Annette should plan to spend 2.25 hours walking back.

The measure of line MN in the secant line using the Intersecting theorem is approximately 19.5.
What is the measure of length MN?Intersecting secants theorem states that " If two secant line segments are drawn to a circle from an exterior point, then the product of the measures of one of secant line segment and its external secant line segment is the same or equal to the product of the measures of the other secant line segment and its external line secant segment.
From the figure:
Sectant line segment QO = 48
internal line segement of QO = QP = 29
External line segement of QO = PO = 48 - 29 = 19
Second sectant line segment MO = NO + MN = ( 22 + x )
External line segement of MO = NO = 22
Using the Intersecting secants theorem:
22( 22 + x ) = 19 × 48
Solve for x:
484 + 22x = 912
22x = 912 - 484
22x = 428
x = 428/22
x = 19.5
Therefore, line MN is approximately 19.5.

For each equation you are given one of the 4 solutions between -360degrees and 360 degrees work out the 4 solutions for tan x = 0.781 tan x = -1 036 tan x = 2.145
These are the four solutions for each given equation within the range of -360 degrees to 360 degrees.
To find the solutions for the given equations involving tangent (tan) functions, we need to solve for the angle (x) that satisfies each equation. Keep in mind that angles in trigonometry are typically measured in degrees.
tan(x) = 0.781:
To find the angle x that satisfies this equation, we can use the inverse tangent function (arctan or tan^(-1)). Taking the inverse tangent of both sides, we have:
x = arctan(0.781)
Using a calculator or a trigonometric table, we find that:
x ≈ 38.08 degrees
Since tangent is a periodic function with a period of 180 degrees, we can add or subtract multiples of 180 to find the other solutions:
x ≈ 38.08 degrees + 180n, where n is an integer
So, the four solutions for tan(x) = 0.781 are approximately:
x ≈ 38.08 degrees, 218.08 degrees, 398.08 degrees, -141.92 degrees
tan(x) = -1.036:
Similarly, using the inverse tangent function, we have:
x = arctan(-1.036)
Using a calculator or a trigonometric table, we find that:
x ≈ -45.14 degrees
Again, considering the periodicity of tangent, we can add or subtract multiples of 180 to find the other solutions:
x ≈ -45.14 degrees + 180n, where n is an integer
The four solutions for tan(x) = -1.036 are approximately:
x ≈ -45.14 degrees, 134.86 degrees, 314.86 degrees, 494.86 degrees
tan(x) = 2.145:
Using the inverse tangent function, we have:
x = arctan(2.145)
Using a calculator or a trigonometric table, we find that:
x ≈ 65.64 degrees
Considering the periodicity of tangent, we can add or subtract multiples of 180 to find the other solutions:
x ≈ 65.64 degrees + 180n, where n is an integer
The four solutions for tan(x) = 2.145 are approximately:
x ≈ 65.64 degrees, 245.64 degrees, 425.64 degrees, -114.36 degrees
These are the four solutions for each given equation within the range of -360 degrees to 360 degrees.

Use the following table to find the probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing. Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Students on the Student Government Board
On-Campus Housing Off-Campus Housing
Freshman 2 2
Sophomore 2 4
Junior 0 3
Senior 4 2
Graduate Student 2 0
The probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing is 8/25 or 0.32 (rounded to the nearest millionth).
1. Calculate the total number of students on the Student Government Board by summing up the numbers in the table:
Total Students = 2 + 2 + 2 + 4 + 0 + 3 + 4 + 2 = 19
2. Calculate the total number of graduate students on the Student Government Board:
Total Graduate Students = 2 + 0 = 2
3. Calculate the total number of students living in on-campus housing:
Total On-Campus Housing = 2 + 2 + 0 + 4 + 2 = 10
4. Calculate the probability of selecting a graduate student from the Student Government Board by dividing the total number of graduate students by the total number of students:
Probability of Graduate Student = Total Graduate Students / Total Students = 2 / 19
5. Calculate the probability of selecting a student living in on-campus housing by dividing the total number of students in on-campus housing by the total number of students:
Probability of On-Campus Housing = Total On-Campus Housing / Total Students = 10 / 19
6. Calculate the probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing by summing up the probabilities from steps 4 and 5:
Probability = Probability of Graduate Student + Probability of On-Campus Housing = 2 / 19 + 10 / 19
7. Simplify the fraction if necessary. In this case, the fraction cannot be simplified further, so the final probability is 2 / 19 + 10 / 19 = 12 / 19.
8. Convert the fraction to a decimal by dividing the numerator by the denominator: 12 / 19 ≈ 0.631578947, which rounds to 0.632 (rounded to the nearest thousandth).
9. Finally, express the probability as a fraction in lowest terms: 12 / 19 is already in lowest terms.
Therefore, the probability that a randomly chosen member of the Student Government Board is a graduate student or lives in on-campus housing is 12/19 or approximately 0.632 (rounded to the nearest thousandth).

Spaghetti sauce comes in large and small cylindrical cans. The larger can has a radius and height that are both three times longer than the radius and height of the smaller can. If the volume of the smaller can is 35.28 in?, what is the volume of the larger can?
The volume of the larger can is approximately 3308.56 cubic inches.
To find the volume of the larger can, we can use the formula for the volume of a cylinder, which is given by V = πr²h, where V represents the volume, r represents the radius, and h represents the height.
Let's assume that the radius of the smaller can is r, and the height is h. According to the problem, the larger can has a radius and height that are both three times longer than the corresponding dimensions of the smaller can. Therefore, the radius of the larger can would be 3r, and the height would be 3h.
Given that the volume of the smaller can is 35.28 in³, we can substitute the values into the formula to solve for the volume of the larger can:
V_small = πr²h
35.28 = πr²h
To find the volume of the larger can, we need to calculate V_large = π(3r)²(3h):
V_large = π(3r)²(3h)
V_large = π(9r²)(3h)
V_large = 27πr²h
Since we know that 35.28 = πr²h from the volume of the smaller can, we can substitute this into the equation for the volume of the larger can:
V_large = 27πr²h
V_large = 27π(35.28)
V_large ≈ 3308.56 in³
Therefore, the volume of the larger can is approximately 3308.56 cubic inches.

Find the equation of the line that goes through the point (-2, -2) and has a slope of -4.
The equation of the line that goes through the point (-2, -2) with a slope of -4 is y = -4x - 10.
To find the equation of a line, we need to use the point-slope form of a linear equation:
y - y₁ = m(x - x₁)
Where (x₁, y₁) is the given point on the line, and m is the slope.
Given that the point is (-2, -2) and the slope is -4, we can substitute these values into the equation:
y - (-2) = -4(x - (-2))
Simplifying:
y + 2 = -4(x + 2)
Expanding the brackets:
y + 2 = -4x - 8
Now, let's rearrange the equation to get it into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept:
y = -4x - 8 - 2
y = -4x - 10
Therefore, the equation of the line that goes through the point (-2, -2) with a slope of -4 is y = -4x - 10.
