if the girls are "g" and the boys are "b"

g + b = 13

b = g + 7 <--- 7 more boys than girls

$\bf g+\boxed{g+7}=13\implies 2g=6\implies g=\cfrac{6}{2}\implies g=3\\\\\\\stackrel{\textit{since there are 3 gals}}{b = g+7}\implies b=3+7$

Complete the parts in each step to find the area of each trapezoid?

Sergio039 [100]

The area of the trapezoid is 20 in².

Solution:

Given data:

Length of the bottom base = 7 in

Length of the top base = 3 in

Height of the trapezoid = 4 in

Step 1: Area of the trapezoid formula,

$$A=\frac{b_{1}+b_{2}}{2} \times h$

Step 2: Substitute the given values in the formula.

$$A=\frac{7+3}{2} \times 4$

Step 3: Add 7 and 3.

$$A=\frac{10}{2} \times 4$

Step 4: Divide 10 by 2, we get

$A=5 \times 4$

Step 5: Multiply 5 by 4, we get

A = 20 in²

The area given in the picture is wrong.

The area of the trapezoid is 20 in².

What number goes in the box?<br> 2 ^ ( ) = (2^7 ÷ 2^9)^3

navik [9.2K]

Answer:

$x=-6$

Step-by-step explanation:

$(\frac{2^{7}}{2^{9}})^{3} \\(\frac{128}{512})^{3} \\(\frac{1}{4})^{3}\\(\frac{1}{4})*(\frac{1}{4})*(\frac{1}{4})\\\frac{1*1*1}{4*4*4} \\\frac{1^{3} }{4^{3} } \\\frac{1}{64} \\2^{x}=\frac{1}{64}\\log 2^x=log\frac{1}{64}\\x*(log(2))=log\frac{1}{64}\\x=\frac{log\frac{1}{64}}{log(2)} \\x=-6$
