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:
y=2x+8
Step-by-step explanation:
All of the choices are in slope-intercept, or y=mx+b form where m is the slope and b is the y intercept. Therefore if the slope is 2, and the y intercept is 8 the equation should be y=2x+8.
If the polygon or the figures are similar then it is
known that the ratios of their corresponding sides and angles are proportional.
In this item we can derive an equation that is,
<span>
AC/AE = AD/AB</span>
Substituting the known values,
<span>
4/7 = 10/AB</span>
<span>AB from the equation is equal to 70/4 or equal to 17 ½. </span>
<span>Just list all elements that belong both to A and to B
A ∩ B = {6,12}</span>
