Step-by-step explanation:
The Volume of the box will be 8000 in.³
What is volume ?
Volume is a three dimensional space occupy by the body of particular shape such as here :
It should be noted that a box has six sides that are equal. In this case, we've been given the side of one of the lengths to be 20 inches.
The volume of a cube is :
V = a³
Therefore, the Volume of the box will be :
V = 20³
V = 8000 in.³
Therefore, the Volume of the box will be 8000 in.³

x – 7y = –11
5x + 2y = -18
Answer:
hope this help you
Step-by-step explanation:
Simplifying
X + -7y = -11
Solving
X + -7y = -11
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '7y' to each side of the equation.
X + -7y + 7y = -11 + 7y
Combine like terms: -7y + 7y = 0
X = -11 + 7y
Simplifying
X = -11 + 7y
------------------------------------------------------------------------------------------------------------
Solving
5x + 2y = -18
Solving for variable 'x'.
Add '-2y' to each side of the equation.
5x + 2y + -2y = -18 + -2y
Combine like terms: 2y + -2y = 0
5x = -18 + -2y
Divide each side by '5'.
x = -3.6 + -0.4y
Simplifying
x = -3.6 + -0.4y

Hi there!
[tex]\large\boxed{x = \frac{24z}{(18 + yz)} }[/tex]
We can begin solving by creating a common denominator:
x · 3 · z = 3xz. This is the denominator that all of the numerators must have in order to work with the fractions.
Multiply each numerator by the missing parts of the common denominator:
[tex]\frac{8 * 3 * z}{3xz} - \frac{y * x * z}{3xz} = \frac{6 * 3 * x}{3xz}[/tex]
Simplify:
[tex]\frac{24z}{3xz} - \frac{yxz}{3xz} = \frac{18x}{3xz}[/tex]
Move all the fractions involving x in the numerator to the right-hand side of the equation:
[tex]\frac{24z}{3xz} = \frac{18x}{3xz} + \frac{yxz}{3xz}[/tex]
Combine fractions:
[tex]\frac{24z}{3xz} = \frac{18x + yxz}{3xz}[/tex]
Multiply both sides by 3xz:
[tex]24z = 18x + yxz[/tex]
Factor out "x" from the terms on the right-hand side:
[tex]24z = x(18 + yz)[/tex]
Divide both sides by (18 + yz)
[tex]\frac{24z}{(18 + yz)} = x[/tex]

M is directly proportional to r^3
When r = 4, M= 160
b) work out the value of r when m = 540
Answer:
r=6
Step-by-step explanation:
Proportions
We know M is directly proportional to [tex]r^3[/tex]
This can be written as
[tex]M=kr^3[/tex]
Where k is the constant of proportionality which will be determined knowing that when r = 4, M= 160. Substituting in the equation above:
[tex]160=k\cdot 4^3[/tex]
[tex]160=k\cdot 64[/tex]
Solving for k:
[tex]k=\frac{160}{64}=2.5[/tex]
The equation is:
[tex]M=2.5\cdot r^3[/tex]
Now find r when M=540:
[tex]540=2.5\cdot r^3[/tex]
Dividing by 2.5:
[tex]216=r^3[/tex]
Taking cube roots:
[tex]r=\sqrt[3]{216}[/tex]
r=6
