Please help i can not figure it out
Alisiya [41]
To solve this problem you need to figure out the volume of the sipping container, and the volume of the tissue box. 
39*19.5*19.5=14,829.75
6.5*6.5*6.5=274.63

In order to figure out how many fits you need to divide
14,829.75/274.63=53.99

The maximum number that you can fit is the box is 53.

Hope this helps

The first question is to identify a pair of similar triangles. The answer for that would be GCB and BEP. they are not the same size but they do both identify as triangles so that is correct. The next question is explain how you know the triangles in part A are similar. Because they have the same points and when they are reflected they stay the same. Last question is find the distances fromB to E and from P to E. That’s simple. 250 feet and 225 feet. Hope this helps!
