Step-by-step explanation:
I'm not sure if this is 100% right this question was kinda messing with my brain , but if it's like asking how much she had in the 4 games all you had to do was add 9+9+9+9 or to make it easier you can just multiply 9 times 4 but I hope this is right.

Answer:
volume = 1809 cm³
Step-by-step explanation:
The ratio of the height of two similar cylinder is 1:3 . The volume of the smaller cylinder is 67 cm³. The volume of the larger cylinder can be computed below:
If 2 object are similar and the ratio of the corresponding sides is x ,then the ratio of their volume is x³.
ratio of height = 1/3
ratio of volume = (1/3)³ = 1/27
volume of smaller cylinder/volume of larger cylinder = 1/27 = 67/x
where
x = volume of the larger cylinder
x = 27 × 67
x = 1809 cm³
volume = 1809 cm³
Answer:
Step-by-step explanation:
I don't exactly know what the problem is asking.
4+3+2=9
Sooo, there are 9 different songs.
You then have to divide 360 by 9 to figure out how many times each song is going to play.
360/9= 40
Each song is going to play 40 times.
I hope that's the answer to the question. If it isn't, this will probably get you closer to the answer.
Good luck! :D
