NEED HELP

the combines volume of all the tanks at an aquarium is 1.25*10^6 gallons. the aquarium plans to install a new dolphin tank with a volume of 250,000 gallons. what will be the total volume of all the tanks at the aquarium after the new dolphin tank is installed?

1.25 + 0.25 = ?

times 10^6

To find the total volume of all the tanks at the aquarium after the new dolphin tank is installed, you need to add the volume of the new dolphin tank to the current combined volume of all the tanks.

Given:
The combined volume of all the tanks at the aquarium is 1.25 * 10^6 gallons.
The volume of the new dolphin tank is 250,000 gallons.

To find the total volume:

Step 1: Add the volume of the new dolphin tank to the current combined volume of all the tanks:
Total volume = Combined volume + Volume of new dolphin tank

Total volume = 1.25 * 10^6 + 250,000

Step 2: Perform the addition:
Total volume = 1.25 * 10^6 + 250,000
Total volume = 1.5 * 10^6 gallons

Therefore, the total volume of all the tanks at the aquarium after the new dolphin tank is installed will be 1.5 * 10^6 gallons.

hint

250,000 = 0.25 *10^6
