Answer:
1 gallon : 25.6 miles
Step-by-step explanation:
So, the way we can find the rate, or ratio between 2 units is to divide one unit by the other unit.
So basically, we see the first set of units is:
2 gallons - 51.2 miles
So basically, for every 2 gallons, there are 51.2 miles.
To find the ratio, or rate, we must find the miles per gallon.
We can do that by dividing both sides by 2:(g=gallons, m=miles)
2g/2=51.2/2m
=
g=25.6
So for every gallon, there is 25.6 miles.
We can write this as:
1 : 25.6

Answer:
6.687898089 = r
Step-by-step explanation:
#3 Circumference is given by
C = 2 * pi *r
We know the circumference is 42
42 = 2 * pi *r
Divide each side by 2 pi
42/2pi = 2pir/ 2pi
21/pi = r
Approximating pi by 3.14
21/3.14 = r
6.687898089 = r
