Answer:

x = 35, ∠ BDE = 130°

Step-by-step explanation:

(4x - 10) and (x + 95) are corresponding angles and are congruent, then

4x - 10 = x + 95 ( subtract x from both sides )

3x - 10 = 95 ( add 10 to both sides )

3x = 105 ( divide both sides by 3 )

x = 35

Thus

∠ BDE = 4x - 10 = 4(35) - 10 = 140 - 10 = 130°

Answer:

\sf slope: \boxed{\bf \frac{1}{3} }

Explanation:

\sf slope :\dfrac{y_2-y_1}{x_2-x_1} =\dfrac{rise}{run} \  \ \  \  where  \ (x_1, \ y_1) ,(x_2, \ y_2)  \ are \ points

Find slope:

\rightarrow \sf \dfrac{x_2-x_1}{y_2-y_1}

<em>insert values</em>

\rightarrow \sf \dfrac{3-5}{-4-2}

<em>simplify</em>

\rightarrow \sf \dfrac{1}{3}

Answer:

128.86 cm^2

Step-by-step explanation:

So to start off we need to find the area of the rectangle.

The formula for the area of a rectangle is l×w.

L stands for the length which is 12 and w is the width which is 11.

So 11 × 12 = 132 cm^2.

Now time for the area of a circle.

The formula for that is \pi r^{2}.

So first we need to do 1 × 1 which is 1.

Then 1 × \pi which is just \pi.

Then we do 132 - \pi which is an irrational number.

It looks like this shortened 128.858407346.

Now rounding to the nearest hundreth it would be 128.86 cm^2.

Hence, the area of the shaded region is 128.86 cm^2.

Find the volume of the rectangular prism.

V = lwh

V = (9)(16)(4)

V = 756 ft^3

Convert to cubic yards:

1 ft^3 = 0.037037037 yd^3

756 * 0.037037037 = 28

So there are 28 cubic yards of dirt he needs.

Multiply this to 25 to find the total cost of the dirt:

28 * 25 = 700

So the project will cost $700

HELP...The volume of a rectangular prism is 36x^6y^8. The length of the prism is 4x^3y^5, and the width of the prism is 3xy^2. W
Margaret [11]

Answer:

H = 3x^2y

Step-by-step explanation:

Given

V = 36x&^6y^8

L = 4x^3y^5

W = 3xy^2

Required

Find the height of the prism

Volume (V) is calculated as:

V =LWH

Substitute values for V, L and W

36x^6y^8 =4x^3y^5 * 3xy^2 * H

Make H the subject

H = \frac{36x^6y^8}{4x^3y^5 * 3xy^2}

H = \frac{36x^6y^8}{4*3x^3*x*y^5y^2}

H = \frac{36x^6y^8}{12x^4*y^7}

Divide:

H = 3x^{6-4}y^{8-7}

H = 3x^2y

The height of the prism is: 3x^2y
