Answer:
1.U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
2.U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
Step-by-step explanation:
We are given that
and 
are different sets
1.We have to construct a universe set U and non empty sets A,B and C so that above set in fact the same
Suppose U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}

{2,3,4,5}
={2}
{2,3,4,5}={2}
={2}
={2}
Hence, 
2.We have to construct a universe set U and non empty sets A,B and C so that above sets are in fact different

A={1,2}
B={2,3}
C={4}

={2,3,4}
={1,2}
={1,2}
={1,2}
{2,3,4}={2}
Hence, 
Answer:
Part A: 480 ounces of water are left in the water tank.
Part B: he will drink 3 tanks of water in 30 days.
Step-by-step explanation:
Part A:
5x8x16 = 6x16 = 1/2x8x16
=640 = 96 = 64
=480
Part B:
4x30 divided by (5x8) = 120 divided by 40 = 3
