Make Sense and Preserve. Grade 9 Council is raising money for class dances by selling spirit T-
Ugo [173]

Answer:

4 dollars or 13 dollars

Step-by-step explanation:

Revenue is the income or increase in net assets that a commercial organization have as a result of offering services.

Revenue is the product of selling price per goods and the number of goods sold. That is:

Revenue = selling price per goods * number of goods sold

Given the revenue function:

R=-n² +17n +200; where n is the increase in the original price of T-shirt.

Since the council wants to make a revenue of $250, hence:

-n² +17n +200 = 250

-n² + 17n - 50 = 0

Solving using a calculator gives:

n = $4 or $13  (to the nearest whole number)

Which equation is quadratic in form?
Rainbow [258]

A quadratic equation refers to an equation with the highest degree of 2. The first equation, 2(x+5)^2 + 8x + 5 + 6 = 0 is the only one with the highest degree of 2 (in (x+5)^2), so that is the quadratic.

I'm assuming you want the total surface area.

This is a trapezoidal prism. The bases are the parallel faces running horizontal (parallel to the ground) and they are congruent trapezoids. The lateral sides are rectangles.

-------------------------------------------------

Lateral Faces:
The back face (hidden from view) is a rectangle that is 12 inches by 3 inches, so it has an area of 12*3 = 36 sq inches

The front slant faces on the left and right are each 3*5 = 15 sq inches in area

The front center lateral face has area of 6*3 = 18 sq inches

The total lateral surface area is 15+18+15+36 = 84 sq inches

-------------------------------------------------

The bases are each the same trapezoid. The trapezoid has two parallel sides of 12 and 6 inches. Call this b1 and b2. The height of the trapezoid is h = 4. Imagine the trapezoid is laid flat in a 2D perspective instead of a 3D one.

The area of one trapezoid is...
A = h*(b1+b2)/2
A = 4*(12+6)/2
A = 4*(18)/2
A = 72/2
A = 36

So the area of both base faces combined is 2*36 = 72

-------------------------------------------------

The total surface area is then found by adding the total lateral surface area (84) and the total base area (72) to get 84+72 = 156

Final Answer: 156 square inches
