I think this question is technically asking
196.20 is what percent of 180, if so it would be 109%

Answer:
Part a) ![SA=458.4\ cm^2](https://tex.z-dn.net/?f=SA%3D458.4%5C%20cm%5E2)
Part b) Added only one side triangular face instead of three side triangular faces
Step-by-step explanation:
we know that
The surface area of a triangular prism is equal to two times the area of the base plus the area of its three triangular faces
so
![SA=2(73.2)+3(104)](https://tex.z-dn.net/?f=SA%3D2%2873.2%29%2B3%28104%29)
![SA=146.4+312](https://tex.z-dn.net/?f=SA%3D146.4%2B312)
![SA=458.4\ cm^2](https://tex.z-dn.net/?f=SA%3D458.4%5C%20cm%5E2)
Riley's error was
![SA=2(73.2)+(104)=250.4\ cm^2](https://tex.z-dn.net/?f=SA%3D2%2873.2%29%2B%28104%29%3D250.4%5C%20cm%5E2)
added only one side triangular face instead of three side triangular faces
Answer:
1) -2x-1 < 3
3) -3x+5 > 14
Step-by-step explanation:
You want x to equal the number that the point is on!
If you solve for #1 or #3 just remeber that when you divide or multiply on both sides of the inequality you must flip the sign!

Answer:
76 balls and 24 bats
Step-by-step explanation:
Set up a system of equations where x is the number of balls and y is the number of bats:
x + y = 100
4.5x + 20y = 822
Solve by elimination by multiplying the top equation by -20, then combine the equations together:
-20x - 20y = -2000
4.5x + 20y = 822
-15.5x = -1178
x = 76
Then, plug in 76 as x in the first equation to solve for y:
x + y = 100
76 + y = 100
y = 24
So, 76 balls and 24 bats were purchased.
