Answer:

120 cm^2.

Step-by-step explanation:

The area of one triangle = 1/2 * base * height

= 1/2 * 8 * 6

= 1/2 * 48

= 24 cm^2

So area of the pentagon = 5 * 24

= 120 cm^2.

Keshad gets paid $2,115 per month plus 6% of his sales. His brother earns $3,157 per month. For what amount of total sales will
julsineya [31]

Answer:

From $17,366.68 sales, Keshad earns more than his brother.

Step-by-step explanation:

Giving the following information:

Keshad gets paid $2,115 per month plus 6% of his sales.

His brother earns $3,157 per month.

<u>First, we will structure the total pay formula:</u>

<u />

Keshad= 2,115 + 0.06x

x= sales

Brother= 3,157

<u>Now, we equal both formulas and isolate x:</u>

2,115 + 0.06x = 3,157

x= $52,616.67

We have determined the indifference point. At $17,366.67 sales, both earn the same.

Keshad= 2,115 + 0.06*17,366.67= $3,157

From $17,366.68 sales, Keshad earns more than his brother.

What is the solution to the inequality below? x^2 &lt; 49
Kisachek [45]

Answer:

−7<x<7

Step-by-step explanation:

Let's find the critical points of the inequality:

x2=49

x=±√49(Take square root)

x=7 or x=−7

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x<−7(Doesn't work in original inequality)

−7<x<7(Works in original inequality)

x>7(Doesn't work in original inequality)

Hope this helped :)
