Suppose a car has a rating of 4.8 gallons per 100 miles. What is the miles-per-gallon rating of this car? 
bezimeni [28]

Answer:

The miles-per-gallon rating of this car is 20.83.

Step-by-step explanation:

This question can be solved by a rule of three.

What is the miles-per-gallon rating of this car?

How many miles for 1 gallon?

4.8 gallons are used for 100 miles. So

4.8 gallons - 100 miles

1 gallon - x miles

4.8x = 100

x = \frac{100}{4.8}

x = 20.83

The miles-per-gallon rating of this car is 20.83.

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.
Tamiku [17]
You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
V=540=\pi r^2*h= \pi r^2*15
Then,
r^2= \frac{540}{15 \pi }
So, r= \sqrt{\frac{540}{15 \pi }}
radius is approximately 3.4cm
*If you cannot see the equations properly please wait till it downloads or refresh the page*
Hope this helps.
