B) $\$45.5$ she will earn for Smith family for 7 hours

C) It would take $12 \ hrs$ for Margie to make $\$78$ when babysitting for the Smith family

Step-by-step explanation:

Given.

Mr. and Mrs. Smith pay Margie $\$6.50$ an hour to babysit their son, Shea.

Mr. and Mrs. Jones pay Margie $8 an hour to babysit their children, Sarah, Susan, and Dawn.

Let x be number of hours.

Solving for Part A.

Amount of Money earn from Smith family = Pay per hour $\times$ Number of hours = $\$ 6.5 \times x= \$ 6.5x$

Solving for Part B.

x=7

Margie earns from smith family for 7 hours = $\$ 6.5x=\$6.5\times7=\$45.5$

Solving for part C.

To find number of hours

No of hour Margie has done babysitting for Smith family $x=\frac{\$78}{\$6.5}=12 \ hrs$

Select the simplification that accurately explains the following statement. (from clever)

gavmur [86]

Answer:

OPTION C

Step-by-step explanation:

We know that $(\textbf{x}^{\textbf{a}} )^{\textbf{b}} \hspace{5mm} \textbf{=} \hspace{5mm} \textbf{x}^{\textbf{a . b}}$

Also, $\textbf{x}^{\textbf{a}}. \textbf{x}^{\textbf{a}} \textbf{=} \textbf{x}^{\textbf{a + a}} \textbf{=} \textbf{x}^{\textbf{2a}}$

Using the above two results, we can say that:

$\sqrt{9} = 9^{\frac{1}{2}}$

$\bigg ( 9^{\frac{1}{2}} \bigg )^2 = 9^{\frac{1}{2}}. 9^{\frac{1}{2}}$

$= 9^{\frac{1}{2} + \frac{1}{2}}$ (Using (ii) result)

$= 9^{1} = \textbf{9}$

Hence, OPTION C is the correct answer.
