Answer: 33 gallons
Step-by-step explanation:
We initially have 130 gallons of a acid solution and we need to change it to a acid solution, and for that it is necessary to evaporate gallons of water.
So, this situation can be mathemtically expressed as follows:
Then:
Isolating :
Hence, we need to evaporate 33 gallons of water.
The sum of all of the exterior angles of any regular polygon is 360 (I'm assuming by decagon you mean a regular dodecagon).
Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.
360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.
Answer should be 4
Explanation: 30 divided by 8 = 3.75
3.75 rounded is 4
