To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag)
5/25 x 100% (because you're trying to find probability of red)
= 20%
2) 5 + 8 = 13 (# of red AND blue)
13/25 x 100% (divide out of the total)
=52%
3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green)
0.2 x 0.48 x 100%
= 9.6%
4) 10 + 12 + 28 = 50 (to find total number of trials)
28/50 x 100%
= 56%
5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner)
= 35</span><span>Its B 20%

Answer:
It is 8 3 pointers and 13 2 pointers
Step-by-step explanation:
8 x 3 = 24
13 x 2 = 26
24 + 26 = 50
Y = 5x - 2
9y = -2x + 10
9y = 3x + 8
y = (3/9)x + 8/9
Answer:
Y=√2
Step-by-step explanation:
We can use the pathagorian theorum: A²+B²=C² now in this case it would be X²+Y²=2² we also know that X and Y are the same number in this problem because they have the same corresponding angle (triangle angles always add to 180 and since we know 2 of the angles are 45 and 90 the remaining angle will also be 45) Because of this we can change our equation to Z²+Z²=2² (I'm using Z so that we do not confuse it with another letter we've already used) from there we can go to Z∧4=2² and then we will solve the equation. Z=√2 Z also equals X and Y therefore Y=√2
I hope this helps and please let me know if there is anything you don't understand I would be happy to clarify!
