Answer:
Step-by-step explanation:
divide 33.25/475 and you'll get 7 cents per flier
Given:
The function that represents how the amount of fuel changes as a function of distance flown is

where x represents miles flown, and f(x) represents the amount of fuel remaining.
To find:
The rate of change for this scenario.
Solution:
The slope intercept form of a linear function is
...(i)
Where, m is the slope or rate of change and b is the y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.
Time = distance/speed
So all you have to do is plug the numbers in and you get the answer
Time = 1,250 kilometres/150 kilometres per hour
Time = 8.333 hours
Answer:
The equation
gives average time spent on 35 rehearsals.
Step-by-step explanation:
We are supposed to find that what question does the equation
finds answer of.
We can see that 35x represents time spent on 35 rehearsals and
is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
After subtracting
hours from 190 hours we will get time spent on 35 rehearsals.


Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.
Therefore, equation
finds average time spent on 35 rehearsals.
