Tyler is building a fish tank in the shape of a sphere that has a diameter of 14 inches. Based on Tyler's research, it is recommended to have no more than 1 goldfish for every 693 cubic inches of water. How many goldfish should Tyler buy for his fish tank? Numerical Answers Expected! Answer for Blank 1:

2

Step-by-step explanation:

Volume of sphere = 4/3(πr3)

radius = diameter/2 = 14/2 = 7

Taking π= 3.14

volume = 4/3 ( 3.14 * 7*7*7)  =4308.08/3 =  1436.03 cubic inches

Number of Goldfish =  1436.03/693 =  2

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).
