I saw the figure of the pie. It is a circle with 8 slices. 4 slices are shaded, the other 4 are not.
So 4/8 or 1/2 of the pie is left.
Mr. Vargas eats 1/4 of the whole pie.
8 slices * 1/4 = 8/4 = 2 slices.
Out of the 4 slices remaining, Mr. Vargas ate 2 slices.
That left 2 slices from the original 8 slices.
2/8 = 1/4 of the pie remained.
Answer:
1,500,000 gallons
Step-by-step explanation:
In this question, we are to calculate the total volume of the aquarium after installing a new dolphin tank.
Mathematically, to calculate this, we simply need to add the the volume of the new dolphin tank to the volume of the things in the aquarium before bringing the dolphin tank.
The volume of all the things in the aquarium before installing the dolphin tank is 1.25 * 10^6 = 1,250,000 gallons
now let’s add the volume of the dolphin tank which is 250,000 gallons
that would be 1,250,000 + 250,000 = 1,500,000 gallons or 1.5 * 10^6 gallons
