Karen- 125
Step-by-step explanation:
Answer 1...
j =3k
2j + k = 875
substituting the first eqn into the 2nd
2(3k) + k = 875
6k+ k =875
7k = 875
k =875/7 =125
thus j = 3(125) =375

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.
