Answer:
The air is .6m^3
Step-by-step explanation:
The volume of a cube is
V = s^3 where s is the side length
The volume of the tank is
V = 1^3 = 1 m^3
The volume of the water is 1 by 1 by .4
V = l*w*h
= 1 *1*.4
= .4 m^3
The difference must be filled by air
1- .4 = .6 m^3
The air is .6m^3

-(4.2+1/2) ÷ (-)(2.3+2/3)
-9/2 ÷ - 8/3
9/2× 3/8

Reorder the terms: 6.25 + -5y + y^2 = -14 + 6.25
Combine like terms: -14 + 6.25 = -7.75 6.25 + -5y + y2 = -7.75
Factor a perfect square on the left side: (y + -2.5)(y + -2.5) = -7.75
Can't calculate square root of the right side (negative). The solution to this equation could not be determined.
