Solid A is dilated using a scale factor of 2⁄5, resulting in Solid B. Solid B is also dilated using a scale factor of 2⁄5, resulting in Solid C. If the volume of Solid B is 72 km^3, what is the volume of Solid A and Solid C?

Answers

Answer 1

Answer:

28.8 and 180

Step-by-step explanation:

you just times B by 2/5 to get C and divide it by 2/5 to get A

C = (72)(2/5) = 28.8 km³

A = (72)/(2/5) = 180 km³

We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

Use the simple interest formula.

You deposit $650 in a savings account. How long does it take an account with an annual interest rate of 5% to earn $178.25 in interest? Round your answer to the nearest tenth.

Answers

Answer:

The Answer is 5.5, rounded to the nearest tenth

Step-by-step explanation:

650 x .05 = 32.5

178.25 ÷ 32.5 = 5.48461538462

5.48461538462 rounds to 5.5

It will take 5 years and 6 months to earn $178.25 in interest.

What is the simple interest?

Simple interest is the borrowing amount added only to the principal amount.

The Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100,

Where S.I. is simple interest, P is principal amount, T is time period and R is interest rate in a year.

Given:

You deposit $650 in a savings account with an annual interest rate of 5% to earn $178.25 in interest.

That means,

178.25 = 650 x 5 x t/100

t = 17825/3250

t = 5.5

Therefore, it will take 5 years and 6 months.
