The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002. Find the average rate of change in the number of public library visits from 1998 to 2002.

A = 0.05 billion visits per year

Step-by-step explanation:

Given that,

The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002.

We need to find the average rate of change in the number of public library visits from 1998 to 2002.

So,

Hence, the required average rate is 0.05 billion visits per year.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
