Answer:
I'm confused are you asking if your answer is correct
Step-by-step explanation:
I) there are 360 degrees in a circle. So subtract all the numbers from 360 to get the angle for econ.
That angle is 65 degrees
ii) If 95 degrees represents 228 books, then 360 degrees represents "x" (total) books. So we have an equation:
<u>95</u> = <u>360</u>
228 x
Solve for x, and we get x = 864
iii) The percentage is 80 degrees out of 360 degrees or 2/9 or roughly 0.222 or 22.2%

Answer:
(A) $260 + $57x = $488
(B) 4 hours
Step-by-step explanation:
(A) We need to find out how many hours of labor he needed to complete the job. That's what the x will represent.
We know that he charged Katy for the parts and for the labor, with an hourly rate of $57.
We need to sum the amount of money he charged for the parts with the hourly rate multiplied by the number of hours he worked.
Let's notice that we multiply the number of hours just to the hourly rate, the price of the parts doesn't depend on how many hours he worked.
That is $260 + $57*x
We know that the total was $488, so we just need to equal the expression before to the total.
$260 + $57x = $488
That's the expression we were looking for.
(B) Let's solve the equation. We need to leave the x alone on one side of the equation.
First, let's subtract $260 on both sides:
$260 + $57x - $260 = $488 - $260
$57x = $228
Now we divide by $57 on both sides:
$57x/$57 = $228/$57
x = 4
He needed 4 hours to do the job.
