The answer is 15. just replace the letters with the numbers they're equal to.
Answer: $0.42
Step-by-step explanation:
The rate at which the average cost of 1 gallon of gasoline is increasing is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the cost after t years.
t represents the number of years.
b represents the initial cost.
r represents rate of growth.
From the information given,
b = $0.31
r = 3% = 3/100 = 0.03
t = 1972 - 1962 = 10 years
Therefore,
y = 0.31(1 + 0.03)^10
y = 0.31(1.03)^10
y = $0.42

The top base is : 14mm
The bottom base is: 36mm
The height is: 15mm
First you need to add the top and bottom bases together and divide it by 2
(14mm + 36mm) / 2
= 50mm/2
=25mm
Then you need to times it by the height
25mm x 15mm = 375mm^2
