Middle school students were asked how they got to school each morning. There were 120 students who said they walked to school. This number represents 30% of the school enrollment. How many students are
enrolled?

400

Step-by-step explanation:

n = 400

if we choose n as the number, we write are able to write an equation, or number problem.

30% of n = 120

now solve.

first we need to convert 30% to fraction form, which is 30/100.

the reciprocal of 30/100 is 100/30. now multiply 120 by 100/30

(120 x 100) / 30 = 400!

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
