Answer:
40%
Step-by-step explanation:
a percentage can also be written as something over 100. x/100. to find the percentage you would set up the proportions as 12/30=x/100. then you cross multiply 12x100 and divide by 30. (this is called the bat and ball method). you end up with 40.
Write out all the solutions from 1 to 10 and add them together
(1^2+3(1)-2)=2
(2^2+3(2)-2)=8
" = 16
" = 32
" = 38
" = 52
" = 68
" = 86
" = 106
" = 128
Add them together: 530

1. If Rachel's free-throw percentage is 60%, you can take 4 index cards away since 100 - 40 = 60%. For example, if those 10 index cards represent 10 free-throws, and her percentage is 60%, just take 60 away from the total (100%).
2. For the simulation, it's the same as problem 1. Since 50 is the total amount of shots she is going to take, and you know she is going make 60% of them, take 60% from 50 which gives you 30. That means she will make 30 of them and miss 20 of them
