Find Volume of 1 tennis ball:
----------------------------------------------
Volume of 1 tennis ball = 4/3 x 3.14 x (2.5 ÷ 2)³
Volume of 1 tennis ball = 8.18 in³
----------------------------------------------
Find Volume of 3 tennis balls:
----------------------------------------------
Volume of 3 tennis balls = 8.18 x 3 = 24.54 in³
----------------------------------------------
Find Volume of teh cylindrical canister:
----------------------------------------------
Volume of the cylindrical canister = 3.14 x 1.5² x (2.5 x 3)
Volume of the cylindrical canister = 52.99 in³
----------------------------------------------
Find unoccupied space:
----------------------------------------------
Unoccupied space = 52.99 - 24.54
Unoccupied space = 28.45 in³
----------------------------------------------
Answer: 28.45 in³

I don’t know this but I need answers sorry
A dozen is 12 jumbo muffins, so 3 dozen is 36 muffins.
We know how much sugar is needed for 8 muffins, and 36 divided by 8 is equal to 4. So we need four times the previous amount.
1.5 tsp x 4 = 6 teaspoons.
The letter x is a placeholder for a number. If we knew what x was, then we can replace it with that number. For now it's unknown.
We start off with x markers in a single box. Then 15 are given out to be left with x-15 markers. This happens exactly 3 times which is what the diagram shows
3 copies of (x-15) = 3*(x-15) = 3x- 45
Put another way, we have 3 'x's that add to 3x, and we have 3 copies of "-15" which combine to -45
So,
3x-45 = 90
3x-45+45 = 90+45 ... add 45 to both sides
3x = 135
3x/3 = 135/3 .... divide both sides by 3
x = 45
Therefore, we started off with 45 markers in each box. If we take 15 away then x-15 = 45 - 15 = 30 markers are left. Then triple this to get 3*30 = 90 which is the total amount left over. This helps confirm the answer.
Final Answer: 45 markers were originally in each box
Answer:
X = 4
Y = 30
