Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 24 feet and a height of 15 feet. Container B has a diameter of 18 feet and a height of 19 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full.
To the nearest tenth, what is the percent of Container A that is empty after the pumping is complete?
To calculate the percent of Container A that is empty after the pumping is complete, we need to calculate the volume of water in Container B and compare it to the volume of Container A.
The volume of a cylinder can be calculated using the formula V = πr^2h, where V is the volume, π is a mathematical constant approximately equal to 3.14159, r is the radius of the base, and h is the height.
Container A:
Diameter = 24 feet
Radius = Diameter / 2 = 24 / 2 = 12 feet
Height = 15 feet
Container B:
Diameter = 18 feet
Radius = Diameter / 2 = 18 / 2 = 9 feet
Height = 19 feet
Now let's calculate the volumes:
Volume of Container A = π * (12^2) * 15 ≈ 6785.4 cubic feet
Volume of Container B = π * (9^2) * 19 ≈ 4848.5 cubic feet
To find the percent of Container A that is empty, we can calculate the ratio of the empty space to the total volume:
Empty space in Container A = Volume of Container A - Volume of Container B
= 6785.4 - 4848.5
= 1936.9 cubic feet
Percent of Container A that is empty = (Empty space / Volume of Container A) * 100
= (1936.9 / 6785.4) * 100
≈ 28.5%
Therefore, to the nearest tenth, approximately 28.5% of Container A is empty after the pumping is complete.[tex][/tex]

The concentration of the drug after 8 hours is equal to 24 mg/L.
The interval over which the concentration increases is 0 < t < 2.
The interval over which the concentration decreases is 2 < t < ∞.
The drug is at its maximum concentration when t = 2 hours and the maximum concentration is 64 mg/L.
After the drug reaches its maximum concentration, the number of hours that are required for the concentration to decrease to 16 mg/L is 8 hours.
After 1 week and 1 month, we can predict that the concentration of the drug kept decreasing after reaching 20 hours.
What is a decreasing function?For any given function, y = f(x), if the output value (range or y-value) is decreasing when the input value is increased, then, the function is generally referred to as a decreasing function.
By critically observing the graph of the given function, we can reasonably infer and logically deduce the following:
The function is increasing over the interval [0, 2] or 0 < t < 2.
The function is decreasing over the interval [2, ∞] or 2 < t < ∞.
In conclusion, the vertex (2, 64) of the graph represent the point where the drug is at its maximum concentration, which is time (t) = 2 hours and the maximum concentration is y = 64 mg/L.

Question 2 Part A (4 points): Given the information below. What is the total length of sides 1 and 2 of the triangle? Show all work! A Instructions K Side 1: 3x² - 4x - 1 Tt Side 2: 4x - x² +5 रु ते Submit
Answer: the total length of sides 1 and 2 of the triangle is 2x² + 4.
Step-by-step explanation:
To find the total length of sides 1 and 2 of the triangle, we need to add the lengths of the two sides together.
Given:
Side 1: 3x² - 4x - 1
Side 2: 4x - x² + 5
To find the total length, we add the lengths of Side 1 and Side 2:
Total length = Side 1 + Side 2
Total length = (3x² - 4x - 1) + (4x - x² + 5)
We can combine like terms:
Total length = 3x² - 4x - 1 + 4x - x² + 5
Combining like terms gives:
Total length = (3x² - x²) + (-4x + 4x) + (-1 + 5)
Simplifying further:
Total length = 2x² + 4
Therefore, the total length of sides 1 and 2 of the triangle is 2x² + 4.

Find the vertices of number 11 and 15
11. The vertices are: Vertex 1: (3/2, 0), Vertex 2: (-3/2, 0), Vertex 3: (0, 1/9), and Vertex 4: (0, -1/9).
15. The vertices are: Vertex 1: (1/4, 0), Vertex 2: (-1/4, 0), Vertex 3: (0, 1/8), and Vertex 4: (0, -1/8).
How did we get these values?To find the vertices of the given equations, rewrite each equation in the standard form of an ellipse, which is
(x - h)²/a² + (y - k)²/b² = 1,
where (h, k) represents the center of the ellipse, "a" represents the distance from the center to the horizontal vertices, and "b" represents the distance from the center to the vertical vertices.
Let's find the vertices for each equation:
11. (4/9) x x² + 81 x y² = 1
To rewrite this equation in the standard form, we need to divide both sides of the equation by 1:
(4/9) x x² + 81 x y² = 1
Dividing through by 1:
(x²)/(9/4) + (y²)/(1/81) = 1
This equation can be rewritten as:
(x²)/(3/2)² + (y²)/(1/9)² = 1
Comparing this with the standard form:
Center: (0, 0)
a = 3/2 (distance from center to horizontal vertices)
b = 1/9 (distance from center to vertical vertices)
Therefore, the vertices are:
Vertex 1: (3/2, 0)
Vertex 2: (-3/2, 0)
Vertex 3: (0, 1/9)
Vertex 4: (0, -1/9)
15. 8 x x² + 16 x y² = 32
To rewrite this equation in the standard form, we need to divide both sides of the equation by 32:
(8/32) x x² + (16/32) x y² = 1/32
Simplifying, we have:
(x²)/(4/32) + (y²)/(2/32) = 1/32
This equation can be rewritten as:
(x²)/(1/4)² + (y²)/(1/8)² = 1
Comparing this with the standard form, we have:
Center: (0, 0)
a = 1/4 (distance from center to horizontal vertices)
b = 1/8 (distance from center to vertical vertices)
Therefore, the vertices are:
Vertex 1: (1/4, 0)
Vertex 2: (-1/4, 0)
Vertex 3: (0, 1/8)
Vertex 4: (0, -1/8)

Debra has two coupons for a jacket.
Coupon A: 30% off of a $36 jacket
Coupon B: $14 rebate on a $36 jacket
Choose the coupon that gives the lower price.
Then fill in the blank with the correct value.
Coupon A gives the lower price.
The price with coupon A is $ less than the price with coupon B.
Coupon B gives the lower price.
The price with coupon B is $ less than the price with coupon A.
The price with coupon B is $25.20 less than the price with coupon A.
To determine which coupon gives the lower price, let's calculate the prices with each coupon.
Coupon A: 30% off of a $36 jacket:
Discounted price = $36 - 30% of $36
Discounted price = $36 - (0.30 × $36)
Discounted price = $36 - $10.80
Discounted price = $25.20
Coupon B: $14 rebate on a $36 jacket:
Discounted price = $36 - $14
Discounted price = $22
Comparing the prices, we can see that Coupon B gives the lower price of $22.
The price with coupon B is $25.20 less than the price with coupon A.

Find the perimeter of a rectangle in simplest expression form that has an area of 6x2 +17x + 12 square feet. Be sure to include an explanation of why/how we factor the numbers.
Help please I need to answer the questions a. b. c. d. e.
I would appreciate it.
The solution to all 5 parts is shown below.
a. To find when the concentration will be 0.5 mg/L, we need to solve the equation:
c(t) = 0.5
20t/ (t²+4) = 0.5
20t = 0.5(t²+4)
20t = 0.5t² + 2
0.5t² - 20t + 2 = 0
Using the quadratic formula, we get:
t = (20 ± √(20²- 4(0.5)(2)))/(2(0.5))
t = (20 ± √(396))/1
t = 10 ± 6√11
So, the concentration will be 0.5 mg/L at t ≈ 0.49 hours and t ≈ 19.51 hours.
b. Using the given function, we can complete the table as follows:
t c(t)
0 0
2 2.35
4 3.64
6 3.16
8 2.22
10 1.53
12 1.08
14 0.76
16 0.53
18 0.37
20 0.26
c. A reasonable domain for this function is all positive real numbers, since the concentration can be measured at any time after administration. The only restriction is that t cannot be 0, since division by 0 is undefined in the given function.
d. To maintain a concentration above 1 mg/L and below 8 mg/L, we need to find the time interval during which the concentration remains within this range.
From the table in part (b), we can see that this interval is between t = 6 hours and t = 14 hours. So, the patient must receive the next intravenous dose of the drug before the concentration drops below 1 mg/L at t = 14 hours.
e. To compare the concentration of the oral drug (#1) and the intravenous drug (#2) over the first 20 hours after administration, we can plot the graphs of the two functions on the same axes.

Bill wants to earn extra money selling lemonade in front of his house.
It costs $1.20 to start his business and each glass of lemonade costs $0.06 to make. He plans to sell the lemonade for $0.10 a glass.
a) Write an equation that represents his cost.
b) Write an equation that represents his revenue.
Graph both equations on the same set of axes.
d) What does the point of intersection mean in this case?
e) Does Bill make a profit or lose money for
i) 20 glasses sold? in) 35 glasses sold? ili) 50 glasses sold?
The amount to start the business, the cost to make a lemonade, and the amount Bill intends to sell a glass of lemonade indicates the costs and revenues are;
a) Cost = 1.20 + 0.06·x
b) Revenue = 0.10·x
c) Please find attached the required graph created with MS Excel
d) The point of intersection is the break even point of the business
e) i) Loses money
ii) Makes money
iii) Makes money
What is a revenue?A revenue is the sum of the amount received by a business for the goods and or services sold within a period.
The cost to start the business = $1.20
The cost of each glass of lemonade = $0.06
The amount he plans to sell a glass of lemonade = $0.10
a) The cost of the lemonade is; C = 1.20 + 0.06 × x
b) The revenue from the sale of the lemonade is R = n × 0.10
c) Please find attached the graph of both equations on the same axis, creates with MS Excel
d) The point of intersection, (30, 3), means that the cost and revenue are the same after selling 30 glasses of the lemonade, which is the breakeven point.
e) The graph and the function indicates that Bill makes 20 × $0.1 = $2 from the sale of 20 lemonade
The cost of 20 lemonade = $1.2 + 20 × $0.06 = $2.4
The cost is more than the revenue, therefore, Bill loses money
ii) 35 glasses sold indicates;
Revenue = 35 × 0.1 = 3.5
Cost = 1.2 + 35 × 0.06 = 3.3
The revenue is more than the cost and therefore, Bill makes a profit
iii) 50 glasses
Revenue = 50 × 0.1 = 5
Cost = 1.2 + 50 × 0.06 = 4.2

How many two or three-digit numbers can you make using the digits 1, 7, 8, 5, and 2?
Answer:
the are so many numbers but here's one of them
Step-by-step explanation:
Since the number is less than 700, it cannot begin with a 7 or an 8.
So the hundreds digit can only be a 2 or a 5.
Now the tens digit can be any digit not occupying the hudreds digit. So there would be 3 possibilities, and there remain two possibilities for the units digit.
Hence, the number of such numbers is 2x3x2 which is 12.
The number of two-digit or three-digit numbers that can be made using the digits 1, 7, 8, 5, and 2 will be 150.
What is a sample?A sample is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.
A dice has six sides, which are given as follows:
1, 2, 3, 4, 5 and 6.
Hence the probabilities for each event are given as follows:
Event A: 4/6 = 2/3 -> outcomes 1, 2, 3 or 4 are desired.Event B: 3/6 = 1/2 -> outcomes are 2, 4 or 6.The events are independent, hence the probability of both events is given by the multiplication of the probabilities of each event, as follows:
2/3 x 1/2 = 1/3.

Answer:
80 degrees
Step-by-step explanation:
Since lines m and n are parallel, angles an and e are equal. Thus, if the sum of angles an and e are 200, then each has a measure of 100. Next, angles e and g are supplementary, which means angle g = 180-100 = 80

Enzo is deciding whether to purchase a regular or a standby bus ticket.
Each time Enzo travels on a bus, he either arrives at his destination on time
or is delayed. The standby ticket is less reliable, but it gives Enzo more
value when it does work because it is cheaper.
Enzo collected data on 200 of each type of bus ticket. Once Enzo decides
which type of ticket to purchase, he plans to purchase 10 tickets.
What is Enzo's expected value If he purchases regular tickets?

Answer:
Here is the expected value for each type of ticket:
Regular ticket:
$20 \cdot 0.73 + $5 \cdot 0.27 = $16.60
Standby ticket:
$40 \cdot 0.27 + $15 \cdot 0.73 = $22.10
Therefore, Enzo should purchase standby tickets to maximize his expected value.
Here is the math behind the expected value calculation:
Regular ticket:
$20 \cdot 0.73 + $5 \cdot 0.27 = ($20 \cdot \frac{146}{200}) + ($5 \cdot \frac{54}{200}) = $16.60
Standby ticket:
$40 \cdot 0.27 + $15 \cdot 0.73 = ($40 \cdot \frac{54}{200}) + ($15 \cdot \frac{146}{200}) = $22.10

Which of the following is a way that you would employ arithmetic in a real-world situation?
a. choosing a grocery item based on a price-per-unit comparison
b. comparing your teammates' batting averages to determine the batting order c. calculating the height of a tree in your front yard
d. estimating how long it will take you to get from school to your soccer game
Answer: (A) choosing a grocery item based on a price-per-unit comparison
Step-by-step explanation: I did the test look at the pic for the entire test answers. It shows the points and score so you know it's correct.
The use of arithmetic in a real-world situation the one that specifically involves arithmetic as a calculation is choosing a grocery item based on a price-per-unit comparison. a.
Comparing prices of grocery items, it is often helpful to look at the price per unit (e.g. price per ounce price per pound price per liter) to determine item is the best value.
This requires calculating the cost per unit using arithmetic.
Comparing batting averages involves arithmetic as well but it is primarily a comparison of numbers rather than a calculation.
Calculating the height of a tree involves the use of trigonometry in addition to arithmetic.
Estimating travel time involves basic arithmetic but also factors such as distance traffic and route planning.
Comparing grocery store pricing it might be useful to look at the price per unit (such as the price per ounce, the price per pound or the price per litre) to determine which item is the better deal.
This involves arithmetic computation of the price per unit.
Math is used while comparing batting averages it is more of a comparison of numbers than a calculation.
In addition to arithmetic trigonometry is used to calculate a tree's height.
Basic mathematics as well as variables like route planning traffic and distance must be considered when estimating trip time.
