So what is the question here? if he is paid $30 an hour for 4 hours that is $120 if the total fee is $170 then the initial fee for the job is $50.
The equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x
<h3>How to determine the equation?</h3>
The attached table of values represents the missing piece in the question.
Start by calculating the rate of change using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (14.77 - 10.55)/(7- 5)
Evaluate
m = 2.11
The equation is then calculated using:
y = m(x - x1) + y1
This gives
y = 2.11(x - 5) + 10.55
Evaluate
y = 2.11x - 10.55 + 10.55
y = 2.11x
Hence, the equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x

Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63
Answer:
It’s important to estimate the amount needed for retirement because if you do not have enough money for bills, food expenses, and extra for emergencies for the rest of your life, you will have to go back to working. Which will be harder because most companies want younger people working instead of older. It also depends on your field of education base for what people they are looking for. So you would want to have enough money for the rest of your life. Which you would make an estimate for a total of your bills and monthly food expense in addition to that emergency so you don’t run out of money for 20-40 years
