Answer:

42ft

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

So that little triangle section:

1/2 * 2 * 3 = 1/2 * 6 = 3

Now we do the rectangle Section:

Area of a rectangle = length * width

So that rectangle is 3 * 7 = 21

If you eliminate those two shapes, you are left with a trapezoid.

Area of a trapezoid is 1/2 * (base 1 + base 2) * height

Base 1 is 3 which is the width of the rectangle.

Base 2 is the 6.

The height is the given 11 feet subtracted by the 7 feet from the length of the rectangle which is 4.

Plug all this in to the formula you get 1/2 * (6 + 3) * 4 = 1/2 * 9 * 4 = 1/2 * 36 = 18.

Now add all of your areas together;

21 + 3 + 18 = 24 + 18 = 42

Which of the following options could represent a possible set of interior angles of a triangle? 100°, 130°, and 130° 30°, 70°, a

omeli [17]

Answer:

2) 30, 70, 80

Step-by-step explanation:

Well there has to be <em>3 angles</em> that all add up to <em>180°</em>.

1)

100+130+130

=360

2)

30+70+80

= 180

3)

25+3+35

=63

4)

45 + 105 + 120

=150

150+120

What is this answer? I have no idea. pls help :( will give brainliest

Artist 52 [7]

The answer is B.

Negative numbers are to the far left if you were using a number line, so -1 to the 3rd power is -1. Everything else is positive. 1/4 is the same as 0.25 which is less than positive 1, positive 8.8 is next and the last would be -5 to the 2nd power which is 25.

What would be the total cost, both fixed and variable, at an activity level of 7,100 units? Assume that this level of activity i

monitta

Answer:

TC = $971,919

Step-by-step explanation:

Given complete question is as follows:

" Cooke Corporation reports that at an activity level of 7,000 units, the total variable cost is $590,730, and the total fixed cost is $372,750.

What would be the total cost, both fixed and variable, at an activity level of 7,100 units? Assume that this level of activity is within the relevant range."

Solution:

- The total cost (TC) is the sum of the fixed cost (FC) and variable cost (VC):

TC = FC + VC

- The fixed cost remains constant at every unit level i.e [email protected],000 = [email protected],100 = $372,750.

- The variable cost VC is a linear function of number of units. The marginal variable cost (MVC) is:

MVC = VC / numbe of units

MVC = 590,730 / 7000

MVC = $84.39/units

- The VC cost @7,100 units is as follows:

[email protected],100 = [email protected],000 + MVC*( 7,100 - 7,000)

[email protected],100 = $590,730 + $84.39/units*( 100 )

[email protected],100 = $590,730 + $8439

[email protected],100 = $599,169

- The total cost for 7,100 units is:

TC = FC + VC

TC = $372,750 + $599,169

TC = $971,919
