The third is because the prove is x = fifteen and if a number is next to a letter, it means multiply, sorry I could only do one.
"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
Answer: 2
Step-by-step explanation:
m = y2 - y1 / x2- x1
where slope is m,
so in this case it would be
m= 1-(-1) / 3-2
m=2/1
m=2
Note that you can do it either way
