Answer:
x = gym memberships, and y = bottles of water
30x + 7y = 1050.....when x = 28
30(28) + 7y = 1050
840 + 7y = 1050
7y = 1050 - 840
7y = 210
y = 210/7
y = 30....so he would have to sell 30 water bottles
Step-by-step explanation:
If the diameter is 10 the radius is 5 and the formula for area of a circle pie r squared so it be
Answer:
339604.65 cubic feet
Step-by-step explanation:
We are given that 1 m is equal to 3.3 ft.
1 m = 3.3 ft
This means that if we find the volume of a cube of 1 m, we have its volume as:

In the same way, the volume of a cube of 3.3 ft (1 m) is:

This means that:

The Kuroshio sea tank has volume of
. Its volume in cubic feet is therefore:

The volume of the tank is 339604.65 cubic feet.
