You are in a pit crew for a driver at a nascar race. the gas weighs 5.92 pounds per gallon. your driver uses 0.25 gallon per lap. with 42 laps to go, you put 60 pounds of fuel in the tank of the car. will your driver finish the race at the same rate without more gas?

a. what values do we already know? what are we trying to find?
b. write an equation to find the number of gallons in 60 pounds of fuel
c. use the equation to solve the problem and explain the meaning of the solution.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
