Answer:
$50
Step-by-step explanation:
Hello There!
We are given that for 1 hour of work 250 dollars is charged and for 3 hours of work 350 dollars is charged
This could also be represented in two points (1,250) and (3,350)
The question wants us to find the hourly charge rate (slope)
we can easily find the slope ( hourly charge rate ) by using the slope formula
we have our two points so all we need to do is plug in the values (remember y values go on top and x values go on the bottom.)
So we can conclude that the hourly charge rate is $50

Area of the shaded region is 540 – 65.25π.
Solution:
Length of the rectangle = 12 + 9 + 6 + 3 = 30 in
Width of the rectangle = 18 in
Radius of the larger circle () = 12 ÷ 2 = 6 in
Radius of the medium circle () = 9 ÷ 2 = 4.5 in
Radius of the smaller circle () = 6 ÷ 2 = 3 in
Area of the shaded region = Area of the rectangle – Area of the larger circle – Area of the medium circle – Area of the smaller circle
Area of the shaded region is 540 – 65.25π.
