Answer:
672 revolutions.
Step-by-step explanation:
Let n represent number of revolutions.
We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.
We know that 1 mile equals to 63360 inches.
We will use circumference of circle formula to solve our given problem.
, where, D represents diameter of circle.
Now, we will set the product of n and circumference of circle equal to 63360 inches as:
Therefore, it will take 672 revolutions for the wheel of car to travel a distance of one mile.
Answer:
Step-by-step explanation:
Upon factoring all terms we are left with the product of
[(x-4)(x+6)(x-6)]/[5(x-6)(3x+5)(x-4)]
The (x-4)s and (x-6)s cancel out and we are left with
(x+6)/(5(3x+5)) which is also equal to
(x+6)/(15x+25)
Answer:
Tenths place
Step-by-step explanation:
Is it the second to last number which makes it the tenths place.
Answer:
792in
Step-by-step explanation:
LxW
=24x7
=168
bxb/2 x H
=24x13/2
=156x4
=624
T= 624+168
=792in
18/1.5 will tell you how many feet. 18/1.5=12 1x12=12, so 12 inch
