Answer:
1/4
Step-by-step explanation:
My key can’t perform this but I can solve it on a sheet...
So here I really hopes this helps
I think after the 9th bounce it will lose 90% of its max height
times 40 by 0.9 which will give you 36
then take 36 away from 40 leaving you with 4.
answer = 4ft
4:1/6 if you add all the instruments you get 120 then you divide it by six and you get 20 snare drums
