Your mom opened a college fund for you when you were born. The fund had an annual interest rate of 2.5%. When you turned 18, the account had earned $4,275 in interest. What was the amount your mom deposited when you were born? Use the formula: I = Prt.

Answers

Answer 1

Answer: Given:
Interest = 4,275
interest rate = 2.5%
term = 18 years
Principal = ?

Interest = Principal * interest rate * term
4,275 = P * 2.5% * 18
4,275/ (2.5% * 18) = P
4,275 / 0.45 = P
9,500 = P

Your mom deposited 9,500 when you were born.

Hera wants to find the volume of the rectangular prism shown below. Which equation could Hera use to find V, the volume of the rectangular prism? A. V = 11 · 14 · 3 B. V = 11 + 14 + 3 C. V = 2(11 · 14 + 14 · 3 + 11 · 3) D. V = (11 · 14 · 3) ÷ 2

Answers

If the rectangular prism gives you its width, length, and height, you just multiply those, so the volume is 11*14*3. If there's anything more complicated going on, I'll need to see the rectangular prism.

The following data points represent the number of points scored last basketball game by each player on the Dragons basketball team.5,8,11,7,?

If the mean of the data set is 8 points, find the missing number of points.

Answers

Answer:

Step-by-step explanation:

There are 5 data points. To find the mean, we add the data and divide by 5

(5+8+11+7+?) /5 = 8

Multiply each side by 5

(5+8+11+7+?) /5 *5 = 8*5

(5+8+11+7+?) = 40

Combine like terms

? + 31 = 40

Subtract 31 from each side

? +31-31 = 40-31

? = 9

The missing number is 9

The missing number is 9.
