here: :)

I did the work, and basically i solved for the area of the faces and then multiplied that by two to get the total surface area of the faces. Then I added in the areas of the sides connecting the two faces:

just as a referral: the formulas to find the faces are as follows:

rectangle: length times width

circle: pi x r^2

trapezoid: h(base1 + base2)

and triangle: (b x h)/2

The stadium vending company finds that sales of hot dogs average 35,000 hot dogs per game when the hot dogs sell for $2.50 each.

Answer:

A function R x that models the total revenue per game is as follows:

Rx = 87,5000 + 3,750x – 500x^2.

Step-by-step explanation:

Based on the information in the question, we have:

Rx = Total revenue per game

x = Number of $0.25 increases in the price of a hot dog

Average sales of hot dogs = 35,000

Effect of each 25 cent increase in the price on average sales = 35,000 - 2000x

Effect of each 25 cent increase in the price on selling price = 2.5 + 0.25x

Therefore, we have:

Rx = (35,000 - 2000x)(2.5 + 0.25x)

This can be solved further by opening the brackets as follows:

Rx = 87,5000 + 8,750x - 5,000x - 500x^2

Rx = 87,5000 + 3,750x – 500x^2

Therefore, a function R x that models the total revenue per game is Rx = 87,5000 + 3,750x – 500x^2.

Answer:

ΔABC ≅ ΔZXN

Step-by-step explanation:

Find the letters of the matching parts of the triangles.

A is the right angle; as is Z.

B is the angle where 10 meets 26; as is X.

C is the remaining angle; as is N.

Corresponding vertices are listed in the same order:

The formula for the area of a triangle is a = zon, where b is the length of the base and h is the height.

katen-ka-za [31]

Answer:

The height is 5 units

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh where b is the base and h is the height

30 = 1/2 (12) h

30 = 6h

Divide each side by 6

30/6 = 6h/6

5 = h

The height is 5 units

Which of the following is a factor of 2x4 + 22x3 + 60x2?

alex41 [277]

For the answer to the question above,
2x^4 + 22x^3 + 60x^2

<span>GCF: 2x^2 </span>

<span>2x^2(x^2 + 11x + 30) =
So the following factor for the problem above is
2x^2(x + 6)(x + 5)
</span>
If you want to double check, just multiply the answer.
I hope my answer helped you.
