If you double the dimensions of the tank, you also double the volume of the tank.
Therefore, volume of the new touch tank = 2000 x 2 = 4000 ft^3

What is the percent of increase in the rent for Bob's apartment if it went from $560 to $616?
son4ous [18]

This is a two step problem. First, you need to find the difference (or increase) in the rent using subtraction.

616-560 = $56 increase

Now we need to figure what percent 56 is to the original amount (560)

We voice it like this:

56 is to 560 as x is to 100.

The equation looks like this:

56/560 - x/100

Cross multiply to cancel out the denominators.

56 x 100 = 560 x

5600 = 560 x

x = 10 percent.

Check it!

What is 10 percent of 560?

560 x .1 = $56

Was that your increase? ... yes.

A certain forest covers an area of 4000 km2. Suppose that each year this area decreases by 7%. What will the area be after 5 yea
Levart [38]
Answer:

2,600

Explanation:

Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
