<u>Ratios and Proportions
</u>
The ratio between two numbers x and y is defined as x/y. It measures how many times y is contained in x. For example 12/8 = 1.5 means 12 is 1.5 times 8.
We have two key sets of data: the ratio between the surface areas of the cylinders and the fact that the radius and heights of the cylinders come in the same proportion.
First, we can easily compute the ratio of the surface areas

It gives us the relation

Computing the square root

Computing the cube

Answer:
City M was colder than City L because -7° > -2°
Step-by-step explanation:
The answer is the option E: E. 8
The explanation is shown below:
1. You have that the triangles shown in the figure attached, are similar, therefore, you can calculate h as following:
(20-4)/h=h/4
16/h=h/h
2. Now, solve for h:
h²=64
h=√64
h=8
