y^2=r^2-x^2 --> square root both sides

y=sqrt(r^2-x^2)

A shoebox has a length of 1 1/4 feet, a width of 1 foot, and a height of 1/2 foot cubes that measure 1/4 foot on each side are p
poizon [28]

The number of cubes that will fit into the shoebox is 40 cubes

<h3>How to calculate the volume of a box</h3>

Volume is the measure of a substance an object contains

Volume of the box = length * width * height

Volume of the box = 5/4 * 1 * 1/2
Volume of the box = 5/8cubic unit

<u />

<u>Determine the volume of the box </u>

Volume of the box = l³

Volume of the box = (1/4)³ = 1/64 cubic units

Number of cubes = (5/8)/(1/64)
Number of cubes = 5/8 * 64/1
Number of cubes = 5 * 8
Number of cubes = 40 cubes

Hence the number of cubes that will fit into the shoebox is 40 cubes

Solve the following absolute value equation.
Ivanshal [37]

So the equation is 2[x + 1] = 6, right? So you’d solve it as follows:

2[x + 1] = 6

Divide both sides by 2

[x + 1] = 3

Subtract one to get x by itself

[x] = 2

If x is 2, then the absolute value of x is the absolute value of 2. The absolute value of 2 is 2 and -2

X = 2 or -2
