RoseWind [281]

Answer:

enrollment decreases by 14.34%.

Step-by-step explanation:

Given that number of students enrolled in 2000 = 823

Given that number of students enrolled in 2010 = 705

705 is less than 823 so that means number of students enrollment is decreasing.

Decrease = 823-705 = 118

Percent decrease is given by formula:

$Percent =\frac{part}{whole}\cdot100 =\frac{118}{823}\cdot100= 14.3377885784$

which is approx 14.34%.

Hence final answer is that enrollment decreases by 14.34%

How long will it take an airplane flying at an average cruising speed of 230 miles per hour to fly 1380 miles?

lora16 [44]

Since it takes one hour to fly 230 miles, and we are looking for the number of hours, we can divide the number of miles we are given by the speed. In this case, we would divide 1380 by 230 to get 6. This means it would take 6 hours for the plane to fly 1380 miles.
