Among the eighth-graders in Michael's school, 70% have siblings. The eighth-grade class is 5/6 the size of the seventh-grade cla

trapecia [35]

Answer:

D. 192

Step-by-step explanation:

This problem involves a few steps. First, you need to determine how many eighth graders you have given that 112 represent 70% of the total number of eighth graders. You can solve this using a proportion:

$\frac{70}{100}=\frac{112}{x}$

Cross-multiply and divide: 70x = 11200 or 70x/70 = 11200/70 or x = 160

Since there are 160 total eighth graders and this is $\frac{5}{6}$ of the amount of seventh graders, we can set up an equation to solve for the total amount of seventh graders:

160 = $\frac{5}{6}$ x

Multiply by the reciprocal of your fraction on both sides:

$\frac{6}{5}$ x 160 = $\frac{5}{6}$ x ( $\frac{6}{5}$ )

Solve for x: x = 192 seventh graders

Perform the indicated operations(7n^2 - 6) - (6n^2 + 9) - (7n + 6)

DerKrebs [107]

Answer:

n²-7n-21

Explanation:

Given the expression:

$\mleft(7n^2-6\mright)-(6n^2+9)-(7n+6)$

First, open the brackets:

$=7n^2-6-6n^2-9-7n-6$

Next, bring the like terms together and simplify:

$\begin{gathered} =7n^2-6n^2-7n-6-9-6 \\ =n^2-7n-21 \end{gathered}$

Roman55 [17]

Answer:

a) A = 36π in² ≈ 113.09 in²

b) $0.98 per slice

c) $0.09 per square inch

Step-by-step explanation:

a) area = πr²

r= diameter/2 = 12/2 = 6

A = π(6)²

A = 36π in² ≈ 113.09 in²

b) s = price per slice

s = 9.75 ÷ 10

s = $0.975 ≈ $0.98

c) price per square inch = price ÷ area

= 9.75 ÷ 113.09

= $0.086 ≈ $0.09 per square inch
