Simple....
What is equivalent to 7(x-3)?
Distributing....
7*x=7x
7*-3=-21
7x-21
Thus, your answer.
The answer is 12 because every 3 pizzas you get 2 side dishes so 8 divided by 2 equals 4 and 4 times 3 is 12. Hope this helps
{18,21,24,27(A),36,37,38(B)}
Increasing hope that helps
Volume of the conical tank = 1/3pi*r^2 * h = 1/3pi * (10/2)^2 * 15 = 125pi cubic feet or 392.7 cubic feet = 392.7 * 7.48 gallons = 2937 gallons.
Volume of the hemispherical tank = 2/3pi * r^3 = 2/3pi * (5.5)^3 = 348.5 cubic feet = 348.5 * 7.8 gallons = 2606 gallons
Hence the conical tank will contain more chemicals
