A- The circumference of the tire is about 7.85 feet
B- The tire will rotate about 672 times to travel 1 mile
Step-by-step explanation:
- The formula of the circumference of a circle is C = π d, where d is the diameter of the circle
- If a circle rotates for n turns and make a distance S, then n =

∵ The diameter of a tire is 2.5 ft
∴ d = 2.5 ft
∵ C = π d, where C is the circumference of tire
∴ C = π(2.5) = 7.85398 ft
∴ C ≅ 7.85 feet
A- The circumference of the tire is about 7.85 feet
∵ The tire have to travel 1 mile
∵ 1 mile = 5280 feet
∴ S = 5280 feet
- To find the number of rotation of the tire divide S by C
∵ n =
∴ n =
≅ 672 revolution
B- The tire will rotate about 672 times to travel 1 mile

Answer:
1=83.08
Step-by-step explanation:
mean=summation of number divided by number
The solution to the given system of equations is
g = 4
h = 2
The ratio 21:14 when divided by 7 on each side, is the smallest ratio that has the same value as 21:14. this becomes 3:2
then multiply both sides by a few different numbers on both sides each ,
for example, 3:2 is the same as
6:4 (3:2 times 2)
9:6 (3:2 times 3)
12:8 (3:2 times 4)
15:10 (3:2 times 5) and so on
the ratio of the right number I
divided by the left on all of them is 1.5
so,
14/10 equals 1.4 (nope)
8/4 equals 2 (nope)
9/6 equals 1.5 (yay)
12/21 equals 0.57 (Lol)
So your answer is 9:6
