Refer to the attachment. :)
So since only 20 dollar bills and the other one is a 50
then
so we find some combos that will work
five 20's make 100
we
notice that we can only have 20's in multipules of 5 to make 100's
becauause 4 20's makes 80 and 3 20's make 60 and 2 20's make40 and none
of those add to 50 evenly to make 100's
(probably confusing but I hope you understand if you think about it)
so we have
5 20's =100
10 20's=200
15 20's=300
20
25
30
35
40
45 20's=900
50 20's=1000
so how many multiplules did we have?
10
but wait, if we havve 1000 in all 20's we still need at least one 50 so we subtract 100
900:9
answe ris 9 stacks
answer is 9 stacks or A
<h3>Answer:</h3>
We know that,
Volume of cone = 1/3πr²h
- 1/3 × π × (7)² × 9
- 49 × 3π
- 147π inches³
So. <u>Correct choice</u> - [B] 147π inches³
The coefficient is 12a because it has a variable (a).
