A library contains 2000 books. There are 3 times as man non fiction books. Write and solve a systems of equations to determine t

icang [17]

Answer:

The number of fiction books is <u>500</u> and non fiction books is <u>1500</u>.

Step-by-step explanation:

Given:

Total book library contains = 2000.

There are 3 times as many non fiction books as fiction books.

Now, to determine the number of non fiction books and fiction books.

Let the fiction books be $x.$

And the non fiction books be $3x.$

Total books = 2000.

Now, to get the number of non fiction books and fiction books we put an equation:

$3x+x=2000.$

$4x=2000.$

Dividing both sides by 4 we get:

$x=500.$

Fiction books = 500.

Non fiction books = $3x=3\times 500=1500.$

Therefore, the number of fiction books is 500 and non fiction books is 1500.

The area of a circular trampoline is 112.07 square feet. What is the radius of the trampoline? Round to the nearest hundredth.

Nina [5.8K]

The trampoline is a circle, so you use A=πr².
Plug in 112.07 in for A since it's the area.
Divide both sides by π to get 35.69.
Take the square root to get 5.97.
