The total amount of water used in the park after the new ride is installed can be expressed in scientific notation as:
8.7 x 10^5 + 7.8 x 10^3 = (8.7 + 0.078) x 10^5 = 8.778 x 10^5
Therefore, the total amount of water used in the park after the new ride is installed is 8.778 x 10^5 gallons.
A school has a pool that makes use of 8.7 X 10^5 gallons of water. They plan to add a ride that would make an additional 7.8 x 10^3 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
