Answer:

Yes

Step-by-step explanation:

For GP, Tn = ar^(n-1), where a = first term and r = common ratio, again,

r = Tn/Tn-1

All we will do is to verify

if T2/T1 = T3/T2

 192/256 = 144/192

 0.75       =  0.75


Conclusion:

 As T2/T1 = T3/T2 which is 0.75  =  0.75, therefore, It is a Geometric Progression (GP)

= 30X = 2100

So X = 2100/30

X = 70

So 70 students were surveyed

Karen and her friends decided to have a water balloon fight! They got 20 water balloons and used 6 liters of water to fill them
olga_2 [115]

Answer:

Amount of water in each balloon = 300 milliliter

Step-by-step explanation:

Given:

Amount of water used in balloon = 6 liter

Number of water balloon  = 20 balloon

Find:

Amount of water in each balloon

Computation:

Amount of water used in balloon = 6 x 1000

Amount of water used in balloon = 6,000 milliliter

Amount of water in each balloon = Amount of water used in balloon / Number of water balloon

Amount of water in each balloon = 6,000 / 20

Amount of water in each balloon = 300 milliliter
