Answer:
14
Step-by-step explanation:
Jack drove 278.2 miles on 19.6 gallons of gasoline. then
278.2 miles - 19.6 gallons
x miles - 1 gallon
Write a proportion:

Cross multiply:

The answer is 0.375 because 1/8=0.125 and 1/4=0.25 so you add the both of them and you get 0.375
These are all linear equations:<span>y = 2x + 1
5x = 6 + 3y
<span>y/2 = 3 − x</span></span>
Answer:
1.44m^3
Step-by-step explanation:
Given data
Number of balls= 8
Diameter of ball = 70cm = 0.7m
Radius= 35cm= 0.35m
We know that a ball has a spherical shape
The volume of a sphere is
V= 4/3πr^3
substitute
V= 4/3*3.142*0.35^3
V= 0.18m^3
Hence if 1 ball has a volume of 0.18m^3
Then 8 balls will have a volume of
=0.18*8
=1.44m^3
