Trapezoid JKLM is is shown below. What is the length in centimeters, of KL
IrinaVladis [17]

The complete question is:

Trapezoid JKLM is shown below.

What is the length, in centimeters, of KL ?

A. 12 cm

B. 10 cm

C. 9 cm

D.  6 cm

The mentioned figure is attached.

Answer:

\large\boxed{option\text{ B. }(\overline{KL})=10cm}

Explanation:

1. KL is the hypotenuse of a right triangle; hence, you can use Pythagora's theorem to find its length.

2. The height 8 cm is one leg of the right triangle.

3. The other leg may be found by difference:

     \overline{ML} -\overline{JK}=15cm-9cm=6cm

4. Now you can use Pythagora's theorem:

hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ (\overline{KL})^2=(8cm)^2+(6cm)^2\\ \\ (\overline{KL})^2=64cm^2+36cm^2=100cm^2\\ \\ (\overline{KL})=10cm

A company reported $50,000 net cash provided by operating activities. It invested $1,000 in equipment and paid $1,000 in dividen
Vinvika [58]

Answer:

The answer is c. $48,000

Step-by-step explanation:

To find the free cash flow, we need to take into account the money that is entering the company and the money that is being used.  Money that we are earning is possitive, and money being spend goes with a minus.

The net cash, the $50,000 is our sales column. And is money entering the company.

The Investment would be our CAPEX or directly we can use it as investment. And this money is being spended.

The dividends, are the payments that we are doing to the board of directors or the share holders. Since we are paying others, we know this money is being used.

The equation here is:

Sales - Investment - Dividends = Free Cash Flow

So it $50,000 - $1,000 - $1,000 = $48,000
