Step-by-step explanation:
For this case we have the following relationship for the number of carpeted cubicles:
Where,
y: total number of cubicles
x: fraction of carpeted cubicles.
Therefore, substituting values we have:
Answer:
The number of carpeted cubicles is given by:
Answer:
<em>Jenn runs faster at 9 minutes/mile.</em>
Step-by-step explanation:
Jana runs 3 miles in 1/3 hour.
1/3 hour is equivalent to 1/3*60 = 20 minutes
The ratio time/distance is the reciprocal of the speed and is greater as the speed is lower and vice-versa.
This ratio for Jana is 20/3=16.7 minutes/mile
As for Jenn, she runs 5 miles in 3/4 hour.
3/4 hour is equivalent to 3/4*60=45 minutes
The ratio time/distance is 45/5=9 minutes/mile
Since Jenn has a lower ration, her speed is greater than Jana's, thus Jenn runs faster.
Answer:
80×t=d
Step-by-step explanation:
t means time so if the train travels 2 hours
80×2=160miles
is a growth
Answer:
The box must be 3 inches in height
Step-by-step explanation:
In this question, we are concerned about calculating the height of the supplies box.
To be able to get the value for the volume, we need to use the mathematical formula.
Since It is a rectangular prism, the volume V = l * b * h
where l, b and h are the length, breadth and height respectively. Now , it is the measurement of the base that is l * b, hence the base area in this question is 6 * 5 = 30 inches^2
The height of the supply box is thus 90/30 = 3 inches high
