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.
Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is
where is the amount of money and
is the number of hours.
Since can be at most 8, this is the case that generates the highest money, so if we plug
we have
