a builder is repairing a length of fence 3 1/3 yards long. he is using a .80 pound box of nails. when he finishes, he notices that he used half the box of nails. how many pounds of nails did the builder use for each yard of fence?​

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

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).

b is the right answer

c and e

step-by-step explanation: c and e seem the most probable because a number less than 2 on a spinner with 4 equal sections would be 25% and e because all of the stacks contain 13 of that card.
