Answer:

40x - 300,000

7,500

Step-by-step explanation:

profit  = revenue - cost

p(x) = 75x - (35x + 300,000)

p(x) = 40x - 300,000

Break even is when profit is zero

40x - 300,000 = 0

40x = 300,000

x = 7,500

danny has a trianglular pyramid all triangles are conguent what is the surface area?​the height is 6in and the width is 5in
Gre4nikov [31]

Answer: The answer is 60 square inches.

Step-by-step explanation:  Given that Danny has a triangular pyramid where all the four triangles are congruent. The height and base of one triangle are 6 inches and 5 inches respectively. We are to find the surface area of the pyramid.

The area of one triangle is given by

A=\dfrac{1}{2}\times\textup{base}\times\textup{height}=\dfrac{1}{2}\times 5\times 6=15~\textup{sq. inches}.

Since the pyramid consists of four congruent triangles, so the surface area of the pyramid will be

S=4\times A=4\times 15=60~\textup{sq. inches}.

Thus, the answer is 60 sq. inches.

CONSTRUCTION Carlos is building a screen door. The height of the door is I foot more than twice its width. What is the width of
-BARSIC- [3]

Answer:

<h2>width = 3 feet</h2>

Step-by-step explanation:

Let h be the height of the door

and w be its width

The statement “The height of the door is I foot more than twice its width”

can be translated mathematically like this :  h = 2w + 1

Let’s solve the equation for w:

h = 2w + 1

⇔ 2w = h - 1

\Leftrightarrow w=\frac{h-1}{2}

now , if the door is 7 feet high then it’s width is equal to :

\Rightarrow \frac{7-1}{2} =\frac{6}{2} =3 \ ft
