Please help khanakeem Kurdistan I need help test

The answer is B. $89.50 for the first one

For the second question it's $1350

Step-by-step explanation:

Percentage commision earned = 10%

Amount needed to pay for concert = $135

Hence, total sales for the week must be :

Let total sales = x

10% of total sales = $135

10/ 100 * x = $135

0.1x = $135

x = $135 / 0.1

x = $1350

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

the correct answer is x/3+10≥32

hope this !
