Answer:

The volume of the model is 321\ m^{3}

Step-by-step explanation:

we know that

The volume of the sphere (model of the earth) is equal to

V=\frac{4}{3}\pi r^{3}

In this problem we have

r=8.5/2=4.25\ m ----> the radius is half the diameter

substitute the values

V=\frac{4}{3}(3.14)(4.25)^{3}=321\ m^{3}

At a gas station, it takes 14 seconds to pump 2 gallons of gas. if the amount of gasoline pumped varies directly with time, how
EleoNora [17]

Answer:

See below:

Step-by-step explanation:

If we do this, we know that 2 gallons takes 14 seconds. (2:14)

Based on that data, we can know that 1 gallon takes 7 seconds. (1:7)

-> 2/14 = 1/7

Now we can multiply by 12 to get 12 gallons on one side.

What we do on one side has to happen to the other side.

So, 12 gallons * 1 gallons = 12 gallons and 12 gallons * 7 gallons = 84 gallons.

So the final answer is 85 gallons,
