Answer:

<h2>1.5 cm²</h2>

Step-by-step explanation:

Substitute <em>a = 0.5 cm</em> to the formula <em>SA = 6a² </em>:

<em>SA = 6(0.5)² = 6(0.5 · 0.5) = 6(0.25) = 1.5 cm²</em>

a = edge length = 0.5 cm

S = surface area of cube

S = 6*a^2

S = 6*(0.5)^2

S = 6*0.25

S = 1.5

<h3>The surface area of the cube is 1.5 square cm</h3>

You can use cm^2 in place of "square cm" to mean the same thing.

ANSWER

Paul and Matt will take
9.9 \: \: hours
to install the floor working together.

EXPLANATION

First, calculate Paul's rate, which is

= \frac{1}{18}

Next, calculate Matt's rate, which is,
= \frac{1}{22}

Let us assume that, Paul and Matt took
x \: hours
to do the work together.

Then, the rate of working together is,

= \frac{1}{x}

Now, add the individual rates and equate to the rate of working together to form an equation that will help us solve for x.

\frac{1}{18} + \frac{1}{22} = \frac{1}{x}

Simplify the left hand side

\frac{11 + 9}{198} = \frac{1}{x}

\frac{20}{198} = \frac{1}{x}

We reciprocate both sides to get (You could have also done cross multiplication).

\frac{198}{20} = \frac{x}{1}

x = 9.9 \: hours

How many endpoints are needed to draw four line segments
Paladinen [302]
If these four line segments are connected (kind of like a square) then only 4 endpoints are needed, but if they are all separate line segments, then you would need a maximum of 8 endpoints because any line segment has 2 endpoints and 4 line segments with 2 endpoints a piece equals 8 endpoints in total. 

I hope this helped! :)
