see explanation

Step-by-step explanation:

7 × = 1

Is an example of the inverse property for multiplication, that is

any number n multiplied by it's reciprocal = 1

given 5m - 4 = 14 ( add 4 to both sides )

5m = 18 ( divide both sides by 5 )

m =

i leave the calculator work to you.

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

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
