The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million
Step-by-step explanation:
AC=AB+BC-cos. AC=100+66-cos. AC=166-0.906. AC=√165.094. AC=12.8

Answer: 33 gallons
Step-by-step explanation:
We initially have 130 gallons of a

gallons of water.
So, this situation can be mathemtically expressed as follows:
Then:
Isolating :
Hence, we need to evaporate 33 gallons of water.
