Set up a proportion.
25/5 = x/8
Cross multiply
25*8 = 200
200/5 = x
x= 40
Answer: They rest for 40 minutes in 8 hours.
Answer:
<em>45 minutes </em>
Step-by-step explanation:
We want to know how long it takes to an airplane to fly a distance of 375 miles, if the speed of the airplane is 500 miles per hour.
For this, we should divide the distance/speed to get the time that the plane needs.
T = 375mi/(500mi/h) = 0.75 hours
The plane needs 0.75 hours or 0.75*60 = 45 minutes to fly that distance.
Answer:
y = -4x + 6
Step-by-step explanation:
For a slope-intercept equation, you need to isolate the y. For this equation, just subtract 4x from both sides to get y on it's own.
Second side = x feet
First side = x - 2 feet
Third side = x - 4 feet
Perimeter is 15 feet
15 = x + x - 2 + x - 4
Solve for x and then plug your x-value back into the three sides given above.
