The answer is D, 32pi
The radius is half the diameter, which is 32. The circumference equation is
or 
So that gives you 32pi
45/14 = a product every 3 minutes and 21 seconds
X represents the number that would be added to the silver cars.
x/40= 4
X=40x4
x=160
Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4
Step-by-step explanation:
Given
- 5x + 3 = 2x - 1
or, 2x + 5x = 3 + 1
or, 6x = 4
or, x = 4/ 6
Therefore x = 2 /3
Hope it will help :)❤
Answer:
7
Step-by-step explanation:
22+54x=20+60x
