Find the are of the pool by dividing the volume by the depth:

1960 / 4 = 490

The pool is 490 square feet.


Area is found by multiplying the length by the width.

Let the width = X

We are told the length is 2.5X ( 2.5 times longer)


So we now have 2.5x * x = 490


2.5x * x = 2.5x^2


Now we have 2.5x^2 = 490


Divide both sides by 2.5:

x^2 = 490/2.5

x^2 = 196

find X by taking the square root of 196:

x = √196

x = 14


The width is 14 feet

The length is 2.5 * 14 = 35 feet

Write As Percent
andrew-mc [135]

To make a fraction a percent, you have to divide the numerator by the denominator. You get a decimal. Multiply the decimal by 100 to get the percent or just move the decimal two places to the right.

So,

1.

Divide 1 by 5 and you get 0.20

Multiply 0.20 by 100. The answer is 20%

2.

Divide 2 by 3 and you get 0.6666.......

Multiply 0.6666..... by 100 and you get 66.6%

3.

Divide 1 by 40 and you get 0.025.

Multiply 0.025 by 100 and you get 2.5%

4.

Divide 4 by 8 and you get 0.5.

Divide 0.5 by 100 and you get 50%.

5.

Divide 12/16 and you get 0.75.

Multiply 0.75 by 100 and you get 75%.

Since t=1 is January
domain is 1 <=t <=12 up to December
try 1 thru 12 to find lowest depth since d (t) is a function of the month which gives depth.
f (month)=depth

4x + y = 2
kkurt [141]
Cancel by elimination 
4x+y=2
x-y=3
5x=5 because the Ys cancel out because it is positive and negative
x=1 when you divide by 5 on both sides to find x
then plug 1 in for x in a equation then solve
4(1)+y=2
4+y=2
y=-2 when you subtract 4 on both sides 
(1,-2)
