Answer:
c= 3/2 or 1.5$
Step-by-step explanation:
c is for the cost of one cup of coffee
6c = 9$
c= 9/6
c= 3/2 or 1.5
Answer:
1. 2/8 = 12/48
2. 18/20 = 99/110
Step-by-step explanation:
If you divide 2 by 8, you get .25. Knowing this, you can just expand it into another form. 12/48 (simplified into 2/8, aka 1/4) would also be .25 if divided. If you divide 18 by 20, you get .9, and same with if you divide 99/110.
Hope this helped! :)
The original volume of the balloon is given by:
V1 = (4/3) * (pi) * (r ^ 3)
Where,
r: radius of the sphere.
Substituting values:
V1 = (4/3) * (pi) * (1 ^ 3)
V1 = (4/3) * (pi) * (1)
Then, the volume of the current sphere is:
V2 = (4/3) * (pi) * ((1 + 2 * (1)) ^ 3)
V2 = (4/3) * (pi) * ((1 + 2) ^ 3)
V2 = (4/3) * (pi) * ((3) ^ 3)
V2 = (4/3) * (pi) * (27)
The relation of volumes is:
V2 / V1 = ((4/3) * (pi) * (27)) / ((4/3) * (pi) * (1))
V2 / V1 = 27/1
Answer:
The ratio of the current volume of the balloon to the original volume of the balloon is:
27: 1
