A direct variation equation to find the number of miles a jet travels in 3 hours if it is flying at a rate of 600 mph can be written as:

y = 600x

Where y represents the number of miles the jet travels in 3 hours and x represents the rate of the jet in mph.
Answered by GPT 3.5
The correct answer choice is: y = 600 * 3

To find the number of hours a tiger will sleep in 7 weeks, we need to multiply the number of hours a tiger sleeps per day (18 to 20) by the number of days in 7 weeks (7 * 7 = 49).

The range of possible hours a tiger will sleep in 7 weeks is 18 * 49 = 882 to 20 * 49 = 980.

Therefore, the correct answer choice is 882 to 980 hours.
