A cube has side length a. The side lengths are decreased to 40% of their original size. Write an expression in simplest form for the volume of the new cube in terms of a.

Answers

Answer 1

Answer: $V=a ^(3)$ originally. Then you reduces the side lengths a so it will be $V=( (2)/(5) a)^(3) = (8)/(125)a^(3)$
Just note that 40% is the same as 2/5.

Find a number that has 4 identical even factors each factor must be greater than one and can have only one and itself as factors

Answers

Answer:

The Number is 16.

Step-by-step explanation:

Given: Number has 4 Factors.

All 4 factors are same and even.

Factor are greater than 12.

Factors can only has 2 factors that is 1 and itself or we can say factors are prime no.

We need to find this number.

We know that there is only 1 number which is even prime.

So, our required factor is 2.

And required Number = 2 × 2 × 2 × 2 = 16

Therefore, The Number is 16.

A number that has only 1 and itself as factors is called a prime number. The only even number (a number divisible by 2) that is also a prime number is 2. So a number that has 2 as its factor 4 times is 8 :)

Sophia exchanged 1000 U.S. dollars for the South African currency, which is called the rand. The exchange rate was 7.15 rand to $1. How many south african rand did sophia get? please explain how you know.Part B

thank you so much!!!

Answers

Part a:-

7.15 rands = 1 dollar

So we are going to MULTIPLY to find out how many rands there are going to be.

1000 × 7.15 = 7150

So, 7150 rands is your answer.

Part b:-

To do this first we will DIVIDE.

6274 ÷ 7.15 ≈ 877.482.......

So, 6274 rands is ABOUT $878.

Par a:- 7150 rands

Part b:- about $878.
