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

$2.75 - 2.5 = 0.25$

use the distributive property to remove parentheses. Simplify your answer as much as possible. 1/2(4y+7)

Anna007 [38]

1/2(4y+7)

Use the distributive property. a(b+c)= ab+ac

1/2*4y= 2y

1/2*7= 3.5

2y+3.5 <---- simplified expression

I hope this helps!

Find the area of an equilateral triangle that has perimeter of 24 m.

mafiozo [28]

we know the perimeter is 24, and is an equilateral triangle, so it has three equal sides, so each side is 24 ÷ 3 = 8.

$\bf \textit{area of an equilateral triangle}\\\\ A=\cfrac{s^2\sqrt{3}}{4}~~ \begin{cases} s=side's\\ \qquad length\\ \cline{1-1} s = 8 \end{cases}\implies A=\cfrac{8^2\sqrt{3}}{4}\\\\\\ A=16\sqrt{3}\implies A\approx 24.71$
