5 0

Answer:

13

Step-by-step explanation:

Volume to find radius: (3\frac{V}{4\pi})^1^/^3

Substitute: (3\frac{9198.1}{4\pi})^1^/^3

Solve: (3(732.3))^1^/^3

2196.9^1^/^3

13≈r

Marlina received her salary on Friday. She spent one-half of her salary on rent and then spent $338 on her electric and water bi
Alenkinab [10]

Answer:

$654

Step-by-step explanation:

Let the amount of money Marlina's received for her salary be x.

We know that she spent 1/2 of her salary on rent and then $338 on her electric and water bill. So, after this, she will have:

x-\frac{1}{2}x-338

Left of her salary.

Next, she spent one half of what was left. So, it will be one-half of the equation. Therefore, she will have spent:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)

Finally, she spent $56 for gas. So, we will subtract 56:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)-56

And we know that after all of the expenses, she will have $102 left. Therefore:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)-56=102

We want to know how much Marlina spent on rent. So, let's find her salary x first.

First, let's distribute the 1/2:

x-\frac{1}{2}x-338-\frac{1}{2}x+\frac{1}{4}x+169-56=102

Combine like terms:

(x-\frac{1}{2}x-\frac{1}{2}x+\frac{1}{4}x)+(-338+169-56)=102

Evaluate:

\frac{1}{4}x-225=102

Add 225 to both sides:

\frac{1}{4}x=327

Multiply both sides by 4:

x=\$ 1308

Therefore, Marlina received a total of $1308 for her salary.

We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:

r=\frac{1}{2}(1308)=\$ 654

And we're done!
