Jamal wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence

den301095 [7]

Answer:

Area of the rectangle = 700 - 2w²

Step-by-step explanation:

In the picture attached one side of the rectangle is Barn.

Two perpendicular sides of the barn are width 'w' and one parallel side to the barn is 'l'.

Jamal has the fencing having length = 700 feet

So, to cover three sides of the rectangle length of wire required = (2w + l) feet

This length should be equal to the length of the wire, which is to be used to cover these three sides.

(2w + l) = 700

l = 700 - 2w ------(1)

Area of the rectangle = lw

By replacing the value of l from equation 1

Area = w(700 - 2w)

Area = 700w - 2w²

If rolando earned $28.50 in 2 hours, how much would he earn in 8 hours?

cricket20 [7]

First, we need to find his unit rate, the amount he earns in 1 hour.

So, we have to divide 28.50 by 2.

That is:

28.50 / 2 = $14.25 per hour

To find the amount he earns in 8 hours, we will need to multiply hourly rate found by "8". So,

14.25 * 8 = $114

<h2>Rolando earns $114 in 8 hours</h2>
