To find the average of a student’s test scores, add the scores and divide by the number of tests. Suppose Ryan scored 85, 92, 88, and 98 on four tests. Write a numerical expression to describe Ryan’s average test score.

Answers

Answer 1
x= (85+92+88+98)/4
The slash means to divide. So you’re making a fraction with all the scores on top and the number of scores on the bottom.
Answer 2

Answer:

(85+92+88+98)/4

Step-by-step explanation:

No equal sign because it is a numerical expression.

The mayor knows the area needed for a flower garden in the park. She wants the base to be a certain length. How can she determine the necessary height to get the correct area of the flower garden? Explain.

Answers

Answer:

Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.

Step-by-step explanation:

Maria would determine the height by dividing the area of the garden by the base

From the question, she has the area and the base.

Also, the garden has the shape of a parallelogram

The area of a parallelogram is the product of the base and the height.

So, when the area is divided by the base, she gets the height

Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days

Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days

Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765

Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50

What is the step by step explanation on how to solve 8 1/2 + 3 4/5? I already know the answer is 12.3 but I just need help on the how to do the work.

Answers

To do this, first add the whole numbers: 8 + 3 = 11. Set that aside for a moment.

To add the fractions, 1/2 + 4/5, you need a common denominator. With 2 and 5, you’d have an LCD of 10.

1/2 = 5/10

4/5 = 8/10

So 1/2 + 4/5 = 5/10 + 8/10 = 13/10

Now, 13 is bigger than 10, so 13/10 is the same as 1 and 3/10.

We’ll add that to the 11 we found back in the beginning and get 11 + 1 and 3/10 = 12 and 3/10 or 12.3.

Question:- Write ⅝ as a percent

Answer:-

[tex] \frac{5}{8} [/tex]

For making it in percentage we need to multiple the fraction with 100

[tex] \frac{5}{8} \times 100\% \\ \frac{5}{ \cancel{8} {}^{ \: \: \: 2} } \times \cancel{100} {}^{ \: \: \: 25} \\ \frac{5 \times 25}{2} [/tex]

Now we will multiple and divide the above equation with 5 for easy solution. Or you can just divide the equation upto decimal for your answer
