Answer:

$165

Step-by-step explanation:

Rachel works for a clothing store. She is paid $150 every week plus a 10% commission on any clothes that she sells.

Let's find the total amount she is being paid per week

Amount paid originally = $150

Percentage Commission = 10%

Commission = 10% of 150

Commission = 0.1×150

Commission = $15

Total amount paid = originally amount + Commission

Total amount paid = $150+$15

Total amount paid =$165

Hence the amount paid to Rachel okus Commission is $165

Simplify Will give brainiest to person who solves all the problems in picture.

Reika [66]

Answer:

$\sqrt{10+4\sqrt{6 }$ = 4.44948

or = $\sqrt{6} + 2$

step by step...solving

10 + 4 $\sqrt{6}$

add/subtract $\sqrt{6}$ ² = 6

=10 + 4 $\sqrt{6}$ + $\sqrt{6}$ ² - 6

Refine

= $\sqrt{6}$ ² + 4 $\sqrt{6}$ + 4

rewrite ↑ as $\sqrt{6}$ ² + 2 $\sqrt{6}$ * 2 + 2²

apply Perfect Square Formula (a + b)² = a² + 2ab +²

a = $\sqrt{6}$ , b=2

= ( $\sqrt{6}$ + 2)²

= $\sqrt \sqrt({6}+ 2)$ 2square

(the 2 square would not fit like i wanted it to)

apply radical rule $\sqrt[n]{a^{n} } = a$ , assuming a ≥ 0

= $\sqrt{6} + 2$

posting others as picture (have an account with Symbolab to help me as well. Just taking too long to type in the step by step if you need it. all pictures have the decimal result.
