Answer:
B. $8
Step-by-step explanation:
Given:
Total payment, T = $160
Hourly rates = $t/hour
= total payment/total time worked
The question said, "worked 12 more hours than the amount she is paid per hour".
Total time worked = (12 + t) hour
Therefore, Hourly rates of payment, t = 160/(12 + t)
t^2 + 12t - 160 = 0
Solving the above quadratic equation,
t = -20 and 8
t = $8
Answer:
The market closed with a rating of 2773 points on Wednesday.
Step-by-step explanation:
Lets start with what we know:
Monday at close it had a rating of 2760 points.
Tuesday it gained 45 points.
Wednesday it had lost 32 points.
Once written out it becomes less intimidating to answer.
Monday + Tuesday + Wednesday = Answer
2760 + 45 - 32
= 2805 - 32
= 2773
The congruence theorem is always the same

Answer:
C
Step-by-step explanation:
It would take 90 degree to rotate clockwise so it will take 360-90=270 degree to rotate counterclockwise
