The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete 1 road project.
The correct response is:
The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete all of their road projects.
This means that for each road project that the crew completes, it takes them 7 weeks.
The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete all of their road projects.
This means that for each road project that the crew completes, it takes them 7 weeks.
Write 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.(1 point)
Responses
y=600/3
y=600×3
y equals 600 times 3
600=3x
600 equals 3 x
3=600x
Responses
y=600/3
y=600×3
y equals 600 times 3
600=3x
600 equals 3 x
3=600x
The correct response is:
y=600×3
This equation represents direct variation, where y represents the number of miles the jet travels in 3 hours, and 600 represents the rate of 600 mph at which the jet is flying.
y=600×3
This equation represents direct variation, where y represents the number of miles the jet travels in 3 hours, and 600 represents the rate of 600 mph at which the jet is flying.

To find the total number of hours a tiger will sleep in 7 weeks, we can multiply the number of hours it sleeps in a day (18 to 20 hours) by the number of days in 7 weeks (49 days).
Minimum hours = 18 hours/day × 49 days = 882 hours
Maximum hours = 20 hours/day × 49 days = 980 hours
Therefore, the correct response is:
882 to 980 hours
Minimum hours = 18 hours/day × 49 days = 882 hours
Maximum hours = 20 hours/day × 49 days = 980 hours
Therefore, the correct response is:
882 to 980 hours
bots correct except the first one. its actually The constant of proportionality is 7. It takes the crew of workers 7 weeks to complete 1 road project.
