A hummingbird flaps its wings 5,000 times a minute when hovering in place. How many times will it flap its wing in 15 seconds
To find out how many minutes Quinesha exercises in 4 weeks, we first need to determine the number of minutes she exercises in one day.
If in 2 days she exercises 50 minutes, then in one day, she exercises 50 minutes divided by 2 days:
50 minutes / 2 days = 25 minutes/day.
Next, we need to find out how many days are in 4 weeks. Since one week has 7 days, 4 weeks would have:
4 weeks * 7 days/week = 28 days.
Finally, to find out how many minutes Quinesha exercises in 4 weeks, we multiply the number of minutes she exercises in one day by the number of days in 4 weeks:
25 minutes/day * 28 days = 700 minutes.
Therefore, Quinesha exercises 700 minutes in 4 weeks.
To find out how many times the hummingbird will flap its wings in 15 seconds, first, we need to determine how many times it flaps its wings in one second.
We know that a hummingbird flaps its wings 5,000 times in one minute.
Thus, we can divide 5,000 by 60 (the number of seconds in one minute) to find out how many times the hummingbird flaps its wings in one second: 5000 / 60 ≈ <<5000/60=83.33>>83.33.
Therefore, the hummingbird flaps its wings approximately 83.33 times in one second.
To calculate the number of flaps in 15 seconds, we multiply the flaps per second by the number of seconds: 15 seconds * 83.33 flaps/second = 1249.95 flaps.
Therefore, the hummingbird will flap its wings approximately 1,250 times in 15 seconds.
In 2 days, Quinesha exercises 50 minutes. At this rate, how many minutes does she exercise in 4 weeks
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?
In the equation y = 7x, the constant of proportionality is 7.
The constant of proportionality represents the rate at which the number of weeks, y, changes for each unit increase in the number of road projects, x.
In this context, the constant of proportionality being 7 means that for every additional road project, it takes a crew of workers approximately 7 weeks to complete all the projects. The constant of proportionality allows us to understand the relationship between the two variables and quantify the rate of change.
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.
A direct variation equation can be represented in the form y = kx, where y is the dependent variable, x is the independent variable, and k is the constant of variation.
In this scenario, the number of miles a jet travels, y, is directly proportional to the time it flies, x. We are given that the jet is flying at a rate of 600 mph, which means that for every hour of flight, it covers 600 miles.
Let's use x to represent the number of hours the jet travels and y to represent the number of miles it covers.
The equation becomes:
y = kx
Since the jet is flying at a rate of 600 mph, the constant of variation, k, would be 600.
Thus, the direct variation equation to find the number of miles a jet travels in 3 hours at a rate of 600 mph would be:
y = 600x
Substituting x = 3 into the equation, we can find the number of miles the jet will travel in 3 hours:
y = 600 * 3
y = 1800
Therefore, the jet would travel 1800 miles in 3 hours.
A tiger sleeps 18 to 20 hours a day. How many hours will a tiger sleep in 7 weeks
To find out how many hours a tiger will sleep in 7 weeks, we first need to determine the number of hours it sleeps in one day.
The range of sleep for a tiger is 18 to 20 hours a day. To find the average, we can add the minimum and maximum sleep hours and divide by 2:
(18 hours + 20 hours) / 2 = 19 hours.
Therefore, on average, a tiger sleeps 19 hours in one day.
Next, we need to determine the number of days in 7 weeks. Since one week has 7 days, 7 weeks would have:
7 weeks * 7 days/week = 49 days.
Finally, we can calculate the total number of hours the tiger will sleep in 7 weeks by multiplying the number of hours it sleeps in one day by the number of days in 7 weeks:
19 hours/day * 49 days = 931 hours.
Therefore, a tiger will sleep approximately 931 hours in 7 weeks.
