Arunner compared how long it took him to run 200 meters to the record time held by a friend. in his first heat, his time was 2.45 seconds greater than his friend's record time. in his second heat, his time was 2 3 8 seconds greater than his friend's record time. in which heat was he fastest? how much less time did he take in that heat than in the other heat?

the answer is y = 11.54

hope this : )

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

ok so what's the question?

step-by-step explanation:

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
