6/5 is 1.2, so it takes 1.2 minutes to run one lap.
This means 21 x 1.2 = the minutes it takes to run 21 laps around the track.
Therefore it takes 25.2 minutes to run around the track 21 times.
Answer:
The value of h(8) = 9
Step-by-step explanation:
Given function as
h(y) = 2y - 7
For y = 8
Put the value of y in given function
So, h(8) = 2 (8) - 7
OR , h(8) = 16 - 7
∴ h(8) = 9
Hence the value of h(8) = 9 Answer
It shall be the letter ........b
<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
