We can rewrite the equation into:
(x-2)^2+y^2=1

Therefore the circle's centre is that (2,0). Since the circle's centre lies on the x axis, the circle must intersect the x-axis.

A clothing company sells slacks that are either blue or gray and pleated or non-pleated. Last month, the company sold 5 times as
qwelly [4]

Answer:

138 pairs

Step-by-step explanation:

The number of blue pleated slacks is 5 times the number of gray pleated slacks, so:

blue\ pleated = 5 * gray\ pleated (eq1)

The number of gray non-pleated is twice the number of blue non-pleated slacks, so:

blue\ nonpleated = 2 * gray\ nonpleated (eq2)

The total number of blue slacks is 333, and the total number of gray slacks is 225, so we have that:

blue\ pleated + blue\ nonpleated = 333 (eq3)

gray\ pleated + gray\ nonpleated = 225 (eq4)

If we add (eq1) and (eq2), we have:

blue\ pleated + blue\ nonpleated = 5*gray\ pleated + 2*gray\ nonpleated (eq5)

Using (eq3) and (eq4) in (eq5), we have:

333 = 2*225 + 3*gray\ pleated

gray\ pleated = 117/3 = 39

From (eq1), we have:

blue\ pleated = 5*39 = 195

From (eq3), we have:

blue\ nonpleated = 333 - 195 = 138

The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
vlabodo [156]

Answer:

<h2>Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4</h2>

Step-by-step explanation:

The volume of a cube is expressed as L³ where L is the length of each side of the cube.

Given volume of a cube = 64in³

On substituting;

64 = L³

Taking the cube root of both sides to determine L we have;

\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4

Therefore the length of a side of a cube is \sqrt[3]{64}\ or\ 4
