Step-by-step explanation:

Based on the information given, we have a diagram with two sides labeled as 17 cm and X cm, and another side labeled as 15 cm.

To find the length of X, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter.

Perimeter = 17 cm + X cm + 15 cm

The perimeter is the total distance around the triangle. Since we have three sides, the perimeter is the sum of the lengths of those sides.

However, it's important to note that we need additional information to solve for X. In a triangle, any two sides must be greater than the third side. So, we need to know the relationship between the lengths of the sides to determine the possible values for X.

The number of sodas sold at the baseball game was 119, while the number of hot dogs sold was 72.

Let's assume the number of sodas sold as 'x' and the number of hot dogs sold as 'y'.

According to the problem, the total number of sodas and hot dogs sold is 191, so we can write the equation:

x + y = 191   ...(1)

The problem also states that the number of hot dogs sold was 47 less than the number of sodas sold. Mathematically, we can express this as:

y = x - 47   ...(2)

To find the values of x and y, we can solve the system of equations (1) and (2). Substituting equation (2) into equation (1), we have:

x + (x - 47) = 191

Simplifying the equation:

2x - 47 = 191

2x = 191 + 47

2x = 238

Dividing both sides by 2:

x = 238/2

x = 119

Substituting the value of x back into equation (2):

y = 119 - 47

y = 72

As a result, the total amount of sodas sold is 119, and the total amount of hot dogs sold is 72.

The value of x for measure of the angle m∠CED subtended by the arc CD at the circumference is equal to 0.4 to the nearest tenth.

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

arc CD = 2(m∠CED)

Also arc CD = 84°

84° = 2(12x + 37)°

12x + 37 = 84/2 {divide through by 2}

12x + 37 = 42

12x = 42 - 37 {collect like terms}

12x = 5

x = 5/12 {divide through by 12}

The equation of the line parallel to y = x - 5 that goes through the point (7, 0) is y = x - 7.

This line has the same slope as the given line and passes through the specified point.

To find the equation of a line parallel to the given line y = x - 5, we know that parallel lines have the same slope.

The slope of the given line is 1, as it has the coefficient of x.

Therefore, the parallel line we are looking for will also have a slope of 1.

We can use the point-slope form of a linear equation to find the equation of the line.

The point-slope form is given by:

y - y₁ = m(x - x₁)

Where (x₁, y₁) is a point on the line and m is the slope.

We are given the point (7, 0), so we can substitute x₁ = 7 and y₁ = 0 into the equation.

Also, since we want a parallel line with a slope of 1, we have m = 1. Substituting these values, we get:

y - 0 = 1(x - 7)

Simplifying, we have:

y = x - 7.

The mean score is  = 53.16.the average of the two middle values:  53.5. there is no repeated value, so there is no mode.

To describe Michael's scores on the math tests, we can consider different measures of central tendency, namely the mean, median, and mode. Each measure provides a different perspective on the typical or representative value of the data.

The mean is calculated by summing up all the scores and dividing by the number of scores. It is affected by extreme values and can be skewed if there are outliers. In this case, Michael's scores are 24, 28, 21, 79, 84, and 93. The mean score is (24 + 28 + 21 + 79 + 84 + 93) / 6 = 53.16.

The median is the middle value when the scores are arranged in ascending or descending order. It is less affected by extreme values or outliers compared to the mean. To find the median, we sort the scores: 21, 24, 28, 79, 84, 93. Since there is an even number of scores, we take the average of the two middle values: (28 + 79) / 2 = 53.5.

The opportunity cost of attending summer school in this scenario is $4,000. Opportunity cost is the value of the next best alternative that must be given up in order to pursue a certain action. In this case, by choosing to attend summer school, you are giving up the opportunity to earn $3,000 from your usual summer job. Additionally, you have to pay $1,000 for tuition, bringing the total opportunity cost to $3,000 + $1,000 = $4,000.

Step-by-step explanation:

The opportunity cost of attending summer school in this scenario is $4,000, which includes both the foregone earnings from the summer job and the cost of tuition.

The potential earnings from a job that you choose not to do are considered an opportunity cost in economics. In this situation, the opportunity cost of attending summer school is both the $3,000 you lose from not working your summer job and the tuition fee of $1,000 you pay for the school. Economic theory suggests that we consider both of these costs because both are expenses that are a direct result of your decision to attend summer school.

9. P(less than 1) = 0

10. P(greater than 10) = 0

11. P(divisible by 2 or 3) = 3/5

Let's consider each probability separately:

P(7):

Since Dave's number is a whole number greater than 0 and less than 11, there are 10 possible numbers he could have chosen (1, 2, 3, 4, 5, 6, 7, 8, 9, 10).

Out of these 10 numbers, only one is 7.

Therefore, the probability that Dave's number is 7 is 1/10.

P(less than 5):

Out of the 10 possible numbers (1, 2, 3, 4, 5, 6, 7, 8, 9, 10), there are four numbers that are less than 5 (1, 2, 3, 4).

Hence, the probability that Dave's number is less than 5 is 4/10, which simplifies to 2/5.

P(odd):

Out of the 10 possible numbers, there are five odd numbers (1, 3, 5, 7, 9). Therefore, the probability that Dave's number is odd is 5/10, which simplifies to 1/2.

P(less than 1):

Since the number must be greater than 0, it cannot be less than 1.

Thus, the probability of choosing a number less than 1 is 0.

P(greater than 10):

Since the number must be less than 11, it cannot be greater than 10.

Thus, the probability of choosing a number greater than 10 is 0.

P(divisible by 2 or 3):

Out of the 10 possible numbers, there are six numbers that are divisible by 2 or 3 (2, 3, 4, 6, 8, 9).

Therefore, the probability that Dave's number is divisible by 2 or 3 is 6/10, which simplifies to 3/5.

Answer: 6 feet

Step-by-step explanation:

The height of the man and the length of his shadow are proportional.

This means that we can use proportions to find the height of the man if we know the length of his shadow.

We can set up a proportion as follows: height of man/length of shadow = (which includes the triangle formed by the man, his shadow, and the man/length constant.

Let's call the constant "k". We don't know the value of "k" yet, but we do know that it will be the same for all similar triangles ground).

Using the measurements given in the problem, we get 6 / 12 = simplifying the left side of the equation gives 1 / 2 = kNow we know that k = 1/2.

We can use this to find the height of the man. Let's call the height "h". We can set up another proportion using the value we just found:h / 12 = 1 / 2

Cross-multiplying gives us: 2h = 12

Simplifying further: h = 6 Therefore, the height of the man is 6 feet.

1.) The angle that cannot be an exterior angle of a regular polygon among 36°, 50°, 30°, and 45° is 30°. The sum of the other three angles is less than 360°.

2.) The angle is -60° as its complement is one-fourth of its supplementary angle based on the given condition.

3.) A rhombus has no volume as it is a 2D shape. However, its area is 24 square cm with a diagonal measure of 4√3 cm.

1.) Among the angles 36°, 50°, 30°, and 45°, the angle that cannot be an exterior angle of a regular polygon is 30°. This is because the sum of the exterior angles of any polygon is always 360°, and the sum of the other three angles (36° + 50° + 45°) equals 131°, which is less than 360°. Therefore, 30° is the angle that cannot be an exterior angle of a regular polygon.

2.) Let's assume the measure of the angle is 'x' degrees. The complement of the angle would be (90 - x) degrees, and the supplementary angle would be (180 - x) degrees. According to the given condition, the complement is one-fourth of the supplementary angle:

90 - x = (1/4)(180 - x)

Multiplying both sides by 4 to eliminate the fraction:

360 - 4x = 180 - x

Simplifying the equation:

3x = 180 - 360

3x = -180

Dividing both sides by 3:

x = -60

Therefore, the measure of the angle is -60 degrees.

3.) A rhombus does not have a volume since it is a two-dimensional shape. Volume is a measure of space, and rhombi are flat shapes with no thickness. However, we can calculate the area of a rhombus.

The formula to calculate the area of a rhombus is given by:

Area = (diagonal 1 * diagonal 2) / 2

In this case, the diagonal measure is 4√3 cm:

Area = (4√3 * 4√3) / 2

Area = (16 * 3) / 2

Area = 48 / 2

Area = 24 square cm

Therefore, the area of the rhombus is 24 square cm.

Alvarado can create 20 different arrangements of plants on the new display stand.

To determine the number of different arrangements of plants that Alvarado can create, we can use the concept of combinations.

When selecting 3 plants out of 6, the order of the plants doesn't matter, since all that matters is which plants are chosen. Therefore, we need to calculate the number of combinations.

The formula for calculating combinations is:

C(n, r) = n! / (r!(n - r)!)

Where:

n is the total number of items (in this case, the total number of plants)

r is the number of items chosen (in this case, the number of plants to be placed on the display stand)

! represents factorial, which is the product of all positive integers up to a given number

Using the values from the problem:

n = 6 (total number of plants)

r = 3 (number of plants to be placed on the display stand)

C(6, 3) = 6! / (3!(6 - 3)!)

C(6, 3) = 6! / (3! × 3!)

C(6, 3) = (6 × 5 × 4) / (3 × 2 × 1)

To achieve a comparable rate of return, Hank would need to earn an interest rate of approximately 0.86% per month, compounded monthly on his ordinary annuity.

To find the interest rate, compounded monthly, that Hank would need to earn on an ordinary annuity for a comparable rate of return, we can use the present value formula for an ordinary annuity.

First, let's calculate the present value of Hank's payments. He made payments of $219 per month for 30 years, so the total payments amount to $219 * 12 * 30 = $78840.

Now, we need to find the interest rate that would make this present value equal to the selling price of the property, which is $195,258.

Using the formula for the present value of an ordinary annuity, we have:

PV = P * (1 - (1+r)[tex]^{(-n)})[/tex]/r,
where PV is the present value, P is the payment per period, r is the interest rate per period, and n is the number of periods.

Plugging in the values we have, we get:
$78840 = $219 * (1 - (1+r)[tex]{(-360)}[/tex])/r.

Solving this equation for r, we find that Hank would need to earn an interest rate of approximately 0.86% per month, compounded monthly, in order to have a comparable rate of return.

Answer: Changing the radius of an object by a given amount has a greater effect on the volume than changing the height by the same amount. The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. If we change the radius by a given amount, say x, the new radius would be r+x. Hence, the new volume would be V' = π(r+x)²h = π(r²+2rx+x²)h = V + 2πrxh + πx²h. We can see that the volume change equals 2πrxh + πx²h. The first term is proportional to both the radius and the height, whereas the second term is proportional to the square of the radius and the height. Assuming that the height change is also x, the new volume would be V'' = πr²(h+x) = V + πr²x. We can see that the volume change is proportional to the radius squared and the change in height. Therefore, changing the radius by a given amount has a greater effect on the volume than changing the height by the same amount.

y = mx + b

In which:

From the table, we have that when h increases by 1, P(h) also increases by 1, hence the slope m is given as follows:

m = 1/1 = 1.

Hence:

P(h) = h + b.

When h = 4, P(h) = 15, hence the intercept b is given as follows:

15 = 4 + b

b = 11.

Hence the rule is:

P(h) = h + 11.

The probability that the date on the penny will be earlier than 1990 is A. 7/15

Probability is the likelihood of an event.

Since Kevin looked at the dates on a random sample of 15 pennies taken from a small jar of pennies. He made the graph shown below to display the data. Kevin will take 1 penny from the jar at random. Based on the data in the graph, what is the probability that the date on the penny will be earlier than 1990?

To find the probability, we proceed as follows

Let P(<1990) = probability that the date on the penny will be earlier than 1990

Now, P(<1990) = n/N where

From the graph

So, substituting these into the equation, we have that

P(<1990) = n/N

P(<1990) = 7/15

So, the probability is A. 7/15

Step-by-step explanation:

if you are not sure what a word means, use the general internet.

that is much faster than putting such a question in here and then waiting for an answer.

e.g.

a pentagon has 5 corners and 5 sides connecting these corners.

as penta is Greek for 5.

for a decagon, well, deca means 10.

so, a decagon has ... ... 10 corners and 10 sides.

the perimeter is the whole way around the object, so, it is the sum of all 10 sides.

therefore one side is

85 in / 10 = 8.5 in
