Thus, the rate of change per gallon of gas is 60 miles per gallon.
A motorcycle consumes 5 gallons of gas for 300 miles and 7 gallons for 420 miles.
<h3>What is
rate of change?</h3>
Rate of change is defined as the change in value with rest to the time is called rate of change.
Now,
Rate of change = Difference B/w volume (i.e. in gallons) /difference in miles
= 420-300/7-2
= 60 gallons/mile
Thus, The required rate of change per gallon of gas is 60 miles per gallon.

Answer:
Option 400p/500-p
Step-by-step explanation:
Let the number of newspaper A sold be 'x'
and the number of newspaper A sold be 'y'
Therefore,
Total revenue = $1x + $1.25y
Total newspapers sold = x + y
Therefore,
according to the question
r = ..........(1)
and,
p =
or
(x + y)p = 100x
or
y =
or
y =
substituting y in 1
r =
or
r =
or
r =
multiply and divide the RHS with 4
we get
r = (400p)÷(500-p)
hence,
Option 400p/500-p
Find the ratio of number of oranges received by John and Steve , you get 9:16
do cross multiplication
9:16
x:75
ignore the decimals
Not sure the question is but 0.6 is rational but pi is irrational and anything with pi in it is irrational too
