Answer:

The following is an income statement using the Contribution format.

...........................Income Statement for Rivieremia Corp................................

Sales ........................................................................$1,500,000

Less Variable Costs................................................($1,200,000)

Contribution Margin..............................................$300,000

Less Fixed Costs....................................................($200,000)

Operating Income .................................................$100,000

Less Tax....................................................................($10,000)

Net Income...............................................................$90,000

Tax = 10% * 100,000 = $10,000

Proving breakeven is $1,000,000.

The breakeven point for a company can be calculated by dividing the Fixed cost by the contribution margin ratio.

Contribution margin ratio = Contribution margin / Sales

= 300,000/1,500,000

= 20%

= Fixed Cost/ Contribution Margin ratio

= 200,000/20%

= $1,000,000

Degree of Operating Leverage = Contribution Margin/ Operating Income

= 300,000/100,000

= 3

A woman walks due west on the deck of a ship at 3 mi/h. The ship is moving north at a speed of 22 mi/h. Find the speed and direc

Minchanka [31]

Answer: The speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.

Step-by-step explanation:

Since we have given that

Speed at which woman walks due west = 3 mi/hr

Speed at which ship moving due north = 22 mi/hr

Now it forms "Pythagorus theorem":

So, it becomes,

$H^2=B^2+P^2\\\\H^2=3^2+22^2\\\\H^2=9+484\\\\H^2=493\\\\H=\sqrt{493}\\H=22.20\ mi/hr$

And the direction of the woman relative to the surface of the water is given by

$\theta=\sin^{-1}x(\dfrac{3}{22.2})=7.76\approx 8^\circ$

Hence, the speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.

Find the length of the arc.

Arte-miy333 [17]

radius=r=7in
Angle=135°

We know

Length if arc=L

$\boxed{\sf L=\dfrac{\theta}{360}\times 2πr}$

$\\ \sf\longmapsto L=\dfrac{135}{360}\times2π(7)$

$\\ \sf\longmapsto L=\dfrac{27}{72}\times 14π$

$\\ \sf\longmapsto L=\dfrac{27}{36}\times 14π$

$\\ \sf\longmapsto L=\dfrac{9}{12}\times 7π$

$\\ \sf\longmapsto L=\dfrac{63π}{12}$

$\\ \sf\longmapsto L=\dfrac{21π}{4}in$
