Given:
The average cost of a computer in the year 2000 is given as:
The average cost of a computer in the year 2008 is given as:
Now, the difference in average cost between the years 2008 and 2000 can be calculated by subtracting the average cost in 2000 from the average cost in 2008.
Framing in equation form, we get:
Difference in average cost (ΔC) is given as:
Therefore, the difference in the costs for a computer between 2008 and 2000 is
Not sure if this is it
The parts shaded represent 4/10, where 10 represents 360 degrees because that is the entire circle, therefore 40% of 360= 144 degrees
Answer:
36 minutes
Step-by-step explanation:
It takes 45 mins to deliver paper on her route.
Let X be the amount of time it takes the brother to complete the route.
The brother works at the rate of 1/x route per min
The girl works at the at the rate of 1/45 route per min
Girl and brother working together works at rate of 1/20 route per min
1/x + 1/45 = 1/20
Multiply through by 180x
180 + 4x = 9x
4x - 9x = -180
-5x = -180
x = -180 / -5
x = 36 mins.
It takes the brother 36 minutes to complete route alone.
