Answer:
the annual rate of inflation r is 0.023
Step-by-step explanation:
Given by the expression:

The average price of a gallon of milk increased from $0.36 in 1913 to $3.53 in 2013.
Let 

n = 2013 - 1913 = 100
replacing our values into the given equation; then the annual rate of inflation r is as follows:

r = 0.023
Hence, the annual rate of inflation r is 0.023
Answer:
The radius of the container is 2
Step-by-step explanation:
the formula for the volume of a cylinder is a = pi*r^2*h, where r is the radius, a is the area, and h is the height.
we input the data from the question into the equation and we get
125.6 = 3.14*(r^2)*10
we simplify and get
12.56 = 3.14*(r^2)
divide both sides by 3.14 and we get 4 = r^2
then, we find the square root of both sides
2 = r
Answer:
1/8 remained
Step-by-step explanation:
1/2 × 3/4 = 3/8
he ate 3/8 out of 4/8 so 1/8 remained
