A complex shape with measurements 11 inches, 6 inches, 6 inches, 11 inches. What is the perimeter of the shape? 44 inches 66 inc

n200080 [17]

Answer:

A. 44 inches

Step-by-step explanation:

1] Add the numbers given 6 + 6 + 11 + 11 = 34 (because you are trying to find the perimeter)

2] Subtract 6 from 11, 11 - 6 = 5

3] do the same to the top 11 - 6 = 5

4] then add the new numbers together along with the given ones. 6 + 6 + 11 + 11 + 5 + 5 = 44

Find the equation of the line with a slope of 2/5 and containing the point (10,6).

Kipish [7]

Use the poin-slope form of the equation of a line:-

y - y1 = m(x - x1) (where m = slope and the point is (x1, y1))

Plugging in the given values:-

y - 6 = 2/5(x - 10)

multiplying through by 5:-

5y - 30 = 2(x - 10)

5y - 30 = 2x - 20

5y = 2x + 10

In standard form the equation is

2x - 5y = -10 (answer)

Carol is going to make a wooden pyramid and then paint it. She drew the net of a square pyramid as shown below to help her plan

rodikova [14]

The given pyramid's total surface area is 3. 24.0 square feet.

Step-by-step explanation:

Step 1:

To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.

There are 3 triangles and 1 square in the figure.

Step 2:

All the triangles are similar.

The surface area of a triangle = $\frac{1}{2} (baselength)(height).$

The similar triangles have a base length of 3 feet and a height of 2.5 feet.

The surface area of 1 similar triangle = $\frac{1}{2} (3)(2.5)= 3.75$ square feet.

The surface area for all the similar triangles = $3.75 (4) = 15$ square feet.

Step 3:

The surface area of a square is the square of its side length. The square has a side length of 3 feet.

The surface area of the square = $a^{2} = 3^{2} =9$ square feet.

Step 4:

To calculate the total surface area we sum up all the individual surface area.

The total surface area = $15 + 9 = 24$ square feet which is the third option.
