A water park has pools, slides, and rides that, in total, make use of 6.7*10^5 gallons of water. They plan to add a ride that would make use of an additional 2.7*10^4 gallons of water. Use scientific notation to express the total gallons of water made use of in the park after the new ride is installed.

To find the total gallons of water used in the park after the new ride is installed, we add the current total gallons of water (6.7*10^5) to the additional water used by the new ride (2.7*10^4):

6.7*10^5 + 2.7*10^4 = 6.7*10^5 + 0.27*10^5
= 6.97*10^5 gallons

Therefore, the total gallons of water used in the park after the new ride is installed is 6.97*10^5 gallons.
