Answer:

use the Dist = rate * time , formula.. I call it the dirt formula ( Di = rt )

Step-by-step explanation:

since the cars are closing their distance at 10 MPH.. this is question wants to know how long before the cars pass when they are 7 miles apart... this would be the same for a car going 10 MPH and needs to get to a location 7 miles away. sooo..

how long does it take to travel 7 miles at 10 MPH?

it takes 7/10 of an hour.. correct :)

.7 * 60 = 42 minutes

in 42 minutes car 2 will pass car 1

Answer:

The radius is 6.1 cm

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

There is a typo in the problem.

We know the volume

950 = 4/3 (3.14) r^3

Multiply each side by 3/4

3/4 *950 = 3.14 r^3

712.5 = 3.14 r^3

Divide each side by 3.14

712.5/3.14 = r^3

226.910828 = r^3

Take the cube root of each side

226.910828 ^ (1/3) = r^3 ^ 1/3

6.099371323 = r

The radius is 6.1 cm
