Can anyone solve this algebra 2 problem? <br> 15^2x-3 = 245<br> Please show work.
DochEvi [55]
15^2x is 225x.  So, we have 225x-3=245.  Adding three to both sides, we get 225x=248.  Dividing by 225, we have x=248/225.

A leaky faucet wastes 3600 gallons of water per year how many quarts of water are wasted per month [1 gallon = 4 quarts]
Natasha2012 [34]

Answer:

1200 Quarts of Water

Step-by-step explanation:

Starting off with 3600 gallons of water, we know that this needs to be changed to quarts, which to do this you multiply it by 4.

3600 x 4 = 14400

This now shows how many quarts of water are wasted every year, but we need it in months. To do this, we divide by twelve because there are 12 months in a year.

14400 / 12 = 1200

This leads you with the answer of 1200 quarts of water being wasted every month.

mezya [45]

Answer:

you times the number by itself the number of times the power is. 10 to the fourth power is 10 times 10 times 10 times 10, etc.

Step-by-step explanation:

For instance 10 to the third power is 1000 because 10 times 10 times 10=1000/

For your example the answer is 2 times 2 times 2 times 2=16. To figure out how much you times it by is if it is to the power of 4, you times it by itself 4 times, power of 5 = times it by itself 5 times, etc. Hope it helps!
