31. A rental car company charges a fixed amount to rent a car per day. Therefore, the cost per mile to rent a car for a given day is inversely proportional to the number of miles driven. If 100 mi is driven, the average daily cost is $0.80 per mile. a. Find the cost per mile if 200 mi is driven. b. Find the cost per mile if 300 mi is driven. c. Find the cost per mile if 400 mi is driven. d. If the cost per mile is $0.16, how many miles were driven?

A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 15 people. The government responds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month? Express your answer as an integer.
What does the index value of 23.1 in 1970 mean? Why? Group of answer choices Gas in 1970 cost 0.231cents per gallon, because the gas price index measures the cost per gallon. Gas in 1970 cost 23.1 times as much as gas in 2000, because the ratio of the gas price index in 1970 to the gas price index in 2000 is 23.1. Gas in 1970 cost 0.231 times as much as gas in 2000, because the ratio of the gas price index in 1970 to the gas price index in 2000 is 0.231. Gas in 1970 cost 23.1cents per gallon, because the gas price index measures the cost per gallon.

The number of phone calls between two cities, N, during a given time period varies the directly as the populations p1 and p2 of the two cities and inversely as the distance, d, between them. If 36,000 calls are made between two cities 310 miles apart and the populations of the cities are 31,000 and a 180,000, how many calls are made between two cities with populations of 80,000 and a 150,000 that are 485 miles apart?

1. Suppose you drive your car on a perfectly flat road at a constant speed with no wind. In thiscase, the amount of fuel, y, (in litre) needed is directly proportional to the distance travelled,x (in kilometre).(a) If the distance travelled increase, what can we say about the amount of fuel needed?(b) If the relationship is given by y = 0.05x and x increase by 50 km, how much does yincrease? (c) Now, suppose it takes 12 litre of fuel to travel 282 km. Find the constant of proportionality.(d) In words, describe the meaning of this constant of proportionality.

Data was collected on the number of pairs of shoes people on and the number of miles they walk per week. R-Squared =0.38. Then 38% of the variation in miles walked can be explained by the linear relationship between the number of shoes own and the miles walked. 62% is attributable to other favtors. True Or False
