4. Additionally, a method of estimating the number of people in a march is to assign someone to a spot on the sidewalk with the job of counting the
number of marchers who pass in 1 minute. Then multiply this number by the minutes it
takes for all marchers to pass that spot.
Use this method to estimate the students who attend your school (or a certain building
on your campus) on a given morning. Count the number of students entering the building
in 1 minute and multiply this number by the minutes it takes the entire group to enter.
5. REFLECTION: What other methods could be used to estimate the size of a large crowd?
Describe how and why the crowd size estimate supplied by event organizers might differ
from estimates made by other groups.

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.
