In 2 days, Quinesha exercises 50 minutes. At this rate, how many minutes does she exercise in 4 weeks?(1 point)
To find out how many minutes Quinesha exercises in 4 weeks, we first need to determine how many minutes she exercises in one day.
Since she exercises for 50 minutes in 2 days, she exercises for 50/2 = <<50/2=25>>25 minutes in one day.
Now we need to determine how many minutes she exercises in one week.
Since there are 7 days in a week, she exercises for 25 x 7 = <<25*7=175>>175 minutes in one week.
Finally, we can find out how many minutes she exercises in 4 weeks.
Since there are 4 weeks in a month, she exercises for 175 x 4 = <<175*4=700>>700 minutes in 4 weeks. Answer: \boxed{700}.
The equation y=7x gives the relationship between the number of road projects, x, and the number of weeks it takes a crew of workers to complete all the projects, y . What is the constant of proportionality? What does it mean in this context?(1 point)
The constant of proportionality in the equation y=7x is 7.
In this context, the constant of proportionality represents the rate at which the number of road projects, x, is proportional to the number of weeks it takes to complete all the projects, y.
By multiplying the number of road projects, x, by the constant of proportionality 7, we can determine the number of weeks, y, it would take the crew of workers to complete all the projects.
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.
The 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 is:
m = 600 * 3
In this equation, m represents the number of miles traveled in 3 hours. The rate of 600 mph is multiplied by the time of 3 hours to determine the distance traveled.
A tiger sleeps 18 to 20 hours a day. How many hours will a tiger sleep in 7 weeks?(
To find the number of hours a tiger will sleep in 7 weeks, we first need to determine the average number of hours it sleeps in a day.
Since a tiger sleeps for 18 to 20 hours a day, let's take the average and assume it sleeps for 19 hours a day.
Now we can calculate the number of hours the tiger will sleep in 7 weeks:
1 week = 7 days
7 weeks = 7 * 7 = 49 days
So, the tiger will sleep for 19 * 49 = 931 hours in 7 weeks.
