Answer:
3 : 1
Step-by-step explanation:
ratio = teeth on front sprocket : teeth on rear sprocket
= 36 : 12 ( divide both parts of the ratio by 12 )
= 3 : 1 ← in simplest form
(2x+24)
(11b-33)
(8s-8)
(36+6y)
(25z-100)
(35w-70)
C = pi * d
Plug in what we know:
C = 3.14 * 26
Multiply:
C = 81.64
Answer:
There is a 30% decrese.
Step-by-step explanation:
Answer: Table D
Step-by-step explanation:
The coefficient of x^2 is -9, the coefficient of x is 7, and the constant is 0, so we know a = -9, b = 7, c = 0.
- This eliminates tables A, B, and C.
Thus, table D is the answer.
