Joan is building a sandbox in the shape of a regular pentagon. The perimeter of the pentagon is 35y4 – 65x3 inches. What is the length of one side of the sandbox?

Answers

Answer 1

Answer: The perimeter of the pentagon is
35y⁴ – 65x³

We let s as the length of one side of the sandbox. Since the sandbox is a pentagon, it's perimeter is given by
P = 5s
5s = 35y⁴ – 65x³
Solving for s
5s = 5(7y⁴ - 13x³)
s = 7y⁴ - 13x³

The length of one side is 7y⁴ - 13x³.

A recipe for 8 servinfs of pudding clls for 2 cups of milk.How many gallons of milk are needed to make enough pudding for 64 servings

Answers

In order to solve this, we first need to know what the ratio of servings of pudding to cups of milk is. We can see that 8 servings of pudding requires 2 cups of milk, so the ratio is 8/2, which can be reduced to 4/1. This means that for every 4 servings of pudding, we will be adding 1 cup of milk. So all we need to do to find out how many cups would be needed for 64 servings of pudding, we simply need to divide by 4.

64 / 4 = 16

So for 64 servings of pudding, we will need 16 cups of milk. But that's not what the question wants to know, it wants to know how many gallons of milk it would need.

In order to find that out, we have to know how many cups there are in one gallon. There are 2 cups in one pint, there are 2 pints in a quart, and there are 4 quarts in a gallon, so we just have to multiply those numbers, and we get 4 * 2 * 2 = 8 * 2 = 16

There are 16 cups in one gallon, therefore, 64 servings of pudding will require 1 gallon of milk.
Hope that helped! =)

that would be b. because u have to calculate it in a caculater then it will show the answer

The only answer would be B. 8.8 would be in a sense where it repeats, but you don't have to write so many 8's. Your, in a way, paraphrasing the decimal.

During the day, the manager of the meat department sold 15.4 pounds of hamburger to one customer and 13.22 pounds to another customer. When the store opened that morning, he had 35.75 pounds of hamburger to sell. How much hamburger does the manager have left to sell? lb

Answers

The total amount of hamburger that the manager of the store in the morning = 35.75 pounds
Quantity of hamburger sold to one customer during the day = 15.4 pounds
Quantity of hamburger sold to another customer during the day = 13.22 pounds
Total quantity of hamburger sold
by the manager during the day = (15.4 + 13.22) pounds
= 28.62 pounds
Then
The quantity of hamburger left in the store to sell = (35.75 - 28.62) pounds
= 7.13 pounds
So 7.13 pounds of hamburger is still left to be sold.

I NEED HELP NOW!!!!! The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the outlier is included, then the mean is 84. Which statement is always true about the new data when the outlier is removed? The mean would decrease
. The mean would increase.
The median would decrease.
The median would increase.

Answers

The median would decrease. The correct option is C.

What is the median?

The average is the value obtained by dividing the sum of the data values by the number of data points, and the median is the midpoint of the given data points. However, for evenly spaced numbers like 2, 4, 6, 8, and 10, the median and average, or 6, are the same.

There are 16 observations in total in this question, and their average is 80. An anomaly with the value 91 exists. This demonstrates that the outlier is greater than the mean. The mean formula is:

Mean = Sum of observations/Number of Observations.

The sum of observations can be calculated by substituting the values in the above formula.

80 = Sum/16.

Sum = 80*16 = 1280.

Subtracting 91 from the total sum will give the sum of the rest of the 15 non-outlier values. Therefore 1280 - 91 = 1189.

Calculating the mean of the 15 values:

Mean = 1189/15 = 79.267 (correct to 3 decimal places).

It is evident that eliminating the outlier lowers the mean. As a result, C is the right response. Since actual values are needed to calculate the median but are missing, the information about the median cannot be determined. C is therefore the right answer.

Answer:

Option C (The mean would decrease).

Step-by-step explanation:

In this question, there are 16 observations and their mean is 80. There is an outlier which has the value 91. This means that the outlier is on the greater side of the mean. The formula for mean is:

Mean = Sum of observations/Number of Observations.

Sum of observations can be calculated by substituting the values in the above formula.

80 = Sum/16.

Sum = 80*16 = 1280.

Subtracting 91 from the total sum will give the sum of rest of the 15 non-outlier values. Therefore 1280 - 91 = 1189.

Calculating the mean of the 15 values:

Mean = 1189/15 = 79.267 (correct to 3 decimal places).

It can be seen that removing the outlier decreases the mean. Therefore C is the correct answer. The information regarding the median cannot be determined since actual values are not present, which are required to calculate the median. Therefore, C is the correct choice!!!

Is y= -4x+3 proportional or non proportional

Answers

y= -4x+3 proportional to x. It means the value of y is directly depend on the value of x

How do we know if an equation is proportional or non proportional?

A proportional table has a constant of proportionality in that y divided by x always equals the same value.
A non-proportional table will have different values when y is divided by x.

example; in the equation y= -4x+3

for different value of x the value of y directly changes.

X=1 than y becomes -1.
X=2 than y becomes -5.
X=-5 than y becomes 23.

The ratio of y/x always gives a constant.
