Add the mileage together to find total miles.
Add the hours together.
Divide total miles by total hours.
305 + 190 = 495 miles
5 + 4 = 9 hours.
495 / 9 = 55 miles per hour.
The average speed was 55 miles per hour.
<u>The total </u><u>labor cost</u><u> of the carpenters is $2296.91</u>

<h3>Conversion of Fraction</h3>
Let's convert the mixed fraction to improper fraction
So, we would have
- 63/4,
- 61/4,
- 35/2,
- 25/2
- 35/2.
<h3>Working Cost</h3>
Let's sum it up and multiply by the working cost per hour
- The total labor cost is = total hours worked * hourly rate.
This becomes 
<u>The total labor cost is $2296.91</u>

Answer: Choice A
The volume expression is 4/3 times pi times (3x)^3
===================================================
The volume of a sphere is found through the formula
V = (4/3)*pi*r^3
so we start with the fraction 4/3, multiply it with pi, and then multiply it with r^3
In this case, the radius is r = 3x because this is half of the diameter d = 6x
We simply replace the r with 3x in that formula above
V = (4/3)*pi*r^3
V = (4/3)*pi*( r )^3
V = (4/3)*pi*(3x)^3 ... replace r with 3x
Arrange in slope intercept form.....
2y = 2x -4
y = x - 2
So, the line would go up......crossing the y axis at -2.........hope this helps
