Answer:
Step-by-step explanation:
hello : here is an solution
"One rotation" would be the circumference of the wheel, which is
C = 2*pi*r, or (here) C = 2*pi*(8 inches) = 16*pi inches.
1 ft
Convert this to feet: 16*pi inches times ---------------
12 inches
Here "inches" cancels out and you are left with (4/3)pi ft.
So, one rotation of the wheel moves you and your bike forward (4/3)pi ft.
Divide this into 700 feet:
700 ft 2100
------------- = --------- rotations = 525 rotations (answer)
(4/3) pi ft 4
The answer is B because 90 to 30 is 3 over 2
Answer:
Both Ivy and Andrey
Step-by-step explanation:
-100, -50, 0, 50 is an arithmetic sequence, because it has a common difference:
-50 − (-100) = 50
0 − (-50) = 50
50 − 0 = 50
The first term is -100 and the common difference is 50, so:
f(n) = -100 + 50 (n − 1)
Simplifying:
f(n) = -100 + 50n − 50
f(n) = -150 + 50n
So both Ivy and Andrey are correct.
