Answer:

0.25

Step-by-step explanation:

Average means $\frac{total \: number}{number \: \: of \: \: individuals}$

According to the formula, each student in Mr. Goldwasser's class read

$\frac{66}{24} = 2.75$

books on average, and each student in Mr. Welch's class read

$\frac{65}{26} = 2.5$

books on average.

Therefore, the answer will be

$2.75 - 2.5 = 0.25$

The plan for the Thorne’s backyard play area, shaped like a trapezoid, is shown. The area of the play area is 286.56 square feet

lorasvet [3.4K]

The length of material needed for the border is the perimeter of the backyard play area

<h3>How to calculate the length of material needed </h3>

The area of the play area is given as:

$Area = 286.56$

The area of a trapezoid is calculated using:

$Area = 0.5 * (L1 + L2) * H$

Where L1 and L2, are the parallel sides of the trapezoid and H represents the height.

The given parameter is not enough to solve the length of material needed.

So, we make use of the following assumed values.

Assume that the parallel sides are: 25 feet and 31 feet long, respectively.

While the other sides are 10.2 feet and 8.2 feet

The length of material needed would be the sum of the above lengths.

So, we have:

$Length = 25 + 31 + 10.2 + 8.2$

$Length = 74.4$

Using the assumed values, the length of material needed for the border is 74.4 feet
