Answer:
25%
Step-by-step explanation:
Its basic division really. The easiest way to think of it is how many times can 3 fit into 12 three fits into 12 four times in fraction that's 1/4 or 1 over 4. Just like the quarter (United States quarter) each one is 25 cents and you need 4 of then to make 1 US dollar or 100% so each group of three is 25 percent. This under standing could work with a variety of numbers 5 is what percent of 20 or 7 is what percent of 28 if it comes in 4s each is 25%. Hope this helps.
The answer is Accuracy. Accuracy is the closeness of a measurement to the actual vaule.

Part 2) ![PE=233\frac{1}{3}\ ft](https://tex.z-dn.net/?f=PE%3D233%5Cfrac%7B1%7D%7B3%7D%5C%20ft)
Step-by-step explanation:
Part 1)
<u><em>Find the distance from B to E</em></u>
To solve this problem I assume that CGRP is a parallelogram
so
Triangles CGB and PEB are similar by AA Similarity Theorem
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
so
![\frac{BG}{BE}=\frac{CB}{PB}](https://tex.z-dn.net/?f=%5Cfrac%7BBG%7D%7BBE%7D%3D%5Cfrac%7BCB%7D%7BPB%7D)
substitute the values
![\frac{400}{BE}=\frac{300}{200}](https://tex.z-dn.net/?f=%5Cfrac%7B400%7D%7BBE%7D%3D%5Cfrac%7B300%7D%7B200%7D)
solve for BE
![BE=400(200)/300](https://tex.z-dn.net/?f=BE%3D400%28200%29%2F300)
![BE=\frac{800}{3}\ ft](https://tex.z-dn.net/?f=BE%3D%5Cfrac%7B800%7D%7B3%7D%5C%20ft)
Convert to mixed number
![BE=\frac{800}{3}\ ft=\frac{798}{3}+\frac{2}{3}=266\frac{2}{3}\ ft](https://tex.z-dn.net/?f=BE%3D%5Cfrac%7B800%7D%7B3%7D%5C%20ft%3D%5Cfrac%7B798%7D%7B3%7D%2B%5Cfrac%7B2%7D%7B3%7D%3D266%5Cfrac%7B2%7D%7B3%7D%5C%20ft)
Part 2)
<u><em>Find the distance from P to E</em></u>
![\frac{CG}{PE}=\frac{CB}{PB}](https://tex.z-dn.net/?f=%5Cfrac%7BCG%7D%7BPE%7D%3D%5Cfrac%7BCB%7D%7BPB%7D)
substitute the values
![\frac{350}{PE}=\frac{300}{200}](https://tex.z-dn.net/?f=%5Cfrac%7B350%7D%7BPE%7D%3D%5Cfrac%7B300%7D%7B200%7D)
solve for PE
![PE=350(200)/300](https://tex.z-dn.net/?f=PE%3D350%28200%29%2F300)
![PE=\frac{700}{3}\ ft](https://tex.z-dn.net/?f=PE%3D%5Cfrac%7B700%7D%7B3%7D%5C%20ft)
Convert to mixed number
![PE=\frac{700}{3}\ ft=\frac{699}{3}+\frac{1}{3}=233\frac{1}{3}\ ft](https://tex.z-dn.net/?f=PE%3D%5Cfrac%7B700%7D%7B3%7D%5C%20ft%3D%5Cfrac%7B699%7D%7B3%7D%2B%5Cfrac%7B1%7D%7B3%7D%3D233%5Cfrac%7B1%7D%7B3%7D%5C%20ft)
Answer:
x = 20
Step-by-step explanation:
angle 2 and 3 are congruent, becaus they are alternate interior angles. So, 3x-10 = x+30, 2x = 40, x= 20.
