Answer:
Step-by-step explanation:
step 1
Find out the number of revolutions in one hour
we know that
The bicycle wheels are making 30 revolutions per minute
One hour are 60 minutes
so
using proportion
step 2
Find out how many feet the bicycle will travel in one hour
we know that
A bicycle moves approximately 7 feet with each revolution and the number of revolutions in one hour is 1,800
so
Multiply the number of revolutions in one hour (1,800 rev) by 7 feet

You would have to do A=lwh which is 2x1x1/2=1
Alex paid for half. That means he paid 15,000. Which seems like a ridiculously expensive pizza. That leaves 15,000 which we divide by 4, to find what his four friends paid. Each friend paid 3,750. Hope that helps! Mark Brainliest if it does. Thank you!
A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
y = kx
Substituting the given values in the ordered pair,
5 = k(4) ; k = 5/4
