These two triangles are similar and the conversion factor is 2/3. This can be found by dividing one side length corresponding to the other on the other triangle.
In this case, DF ~ AC
DF = 12
AC = 18
12/18 = 2/3
Knowing this, we can multiply 15 by 2/3 to find the length of DE because side lengths AB and DE are similar.
15 • 2/3 = 10
DE = 10
A. 5, Six ads have more than 25 words, but one ad has more than 50.
A. 204, We can estimate the percentage of shoppers that bought less than 30 items to be 25+15+10. Our estimation equals about 200 shoppers. Now, our estimation was a little low, so 204 is a logical answer.
Answer:
5
Step-by-step explanation:
we just figure it out by making an equation
3x = 6th graders
4x = 7th graders
35 = total
so
3x + 4x = 35
7x = 35
x = 5
sooooo
3(5)= 15 = 6th graders
4(5) = 20 = 7th graders
SOOOO
20-15 = 5
