Reducing your meat consumption by 1/5 would reduce your energy consumption more that switching from a standard car to a hybrid.

Police use the formula to estimate the speed s of a car in miles per​ hour, where d is the distance in feet that the car skidded and f is the coefficient of friction. If the coefficient of friction on a certain dry road is 0.83 and a car was traveling on it at a rate of 30 mph, how far will the car​ skid? (Round to the nearest​ foot.)

Which is not true of famines?

Steve invests in a circus production. The cost includes an overhead of​ $80,000, plus production costs of​ $4,000 per performance. A​ sold-out performance brings in​ $12,000. Let x represent the number of​ sold-out performances and write the linear profit function​,​ P(x).

Brittany’s collection of beanie babies was worth $2,003 in 1994. By 1997 it had grown to $2,636. Let f(x)  be the value of the investment in the year, x, where x = 0 represents 1994.  Write a linear equation that models the value of the investment in the year x. 

Wind can equal or exceed water as an erosive force in a dry climate on flat land.
