When using the given diagram to determine the area of the gray polygon by decomposition, which statements are correct?:

Answer choices:
(A) Area B = 15 x 3
(B) Area B = 27 x 3
(C) Area A = 11 x 12
(D) The total area of the gray polygon is 213 m²
(E) The total area of the gray polygon is 177 m²

Answer:

B

Step-by-step explanation:

Choose an x point. Then plug it in and see if you get the correct y.

For example, I chose an x point of -1. When x = -1, you can see that y = 4.

Plug it in to the equations, and you find that B is correct.

y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1

4 = 1 - (-2) + 1

4 = 1 + 2 + 1

4 = 4

Answer:

  non-proportional

Step-by-step explanation:

The "+5" means that y is not zero when x is zero. A proportional relation has no added constant. It is of the form ...

  y = kx

The relation is non-proportional.

for number 1, if you look in the upper left hand corner, you will have the answer for the first statement

========================================================

Explanation:

The three angles of this triangle are

The square angle marker represents 90 degrees. It's also referred to as "a right angle".

As a rule, the three angles of any triangle always add to 180. Let's use this fact to solve for x

(angle1)+(angle2)+(angle3) = 180

(20x)+(90)+(26x-2) = 180

(20x+26x) + (90-2) = 180

46x+88 = 180

46x = 180 - 88 .... subtract 88 from both sides

46x = 92

x = 92/46 ........ divide both sides by 46

x = 2

Now that we know what x is, we can find angle A

angle A = 20x = 20*2 = 40 degrees

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

As extra info, we could also find the other angle with this x value

26x - 2 = 26*2 - 2 = 52 - 2 = 50 degrees

The three angles of the triangle are: 40, 50, 90 which add to 40+50+90 = 180. This helps confirm our answer.

Perpendicular = 31.73 ft (Approx)

Step-by-step explanation:

Given:

Length of rope (Hypotenuse) = 36 ft

Base = 17 ft

Find:

Height of pole (Perpendicular)

Computation:

Perpendicular = √Hypotenuse² - Base²

Perpendicular = √36² - 17²

Perpendicular = √1,296 - 289

Perpendicular = 31.73 ft (Approx)

Answer:

The value of x is approximately 5

Step-by-step explanation:

Answer:

x=6.36

Step-by-step explanation:

In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:

[tex]9=x\sqrt{2}[/tex]

Multiply both sides by [tex]\sqrt{2}[/tex]

[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]

Divide both sides by 2

[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]

[tex]x=6.36[/tex] (this answer is approximate)

Therefore, x is equal to 6.36.

Answer:

d

Step-by-step explanation:

The standard deviation of T is equivalent to 5.

       [tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]

Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.

We can write that -

5 = √∑(x{i} - 10)²/√3

√∑(x{i} - 10)² = 5√3

(√∑(x{i} - 10)²)² = (5√3)²

∑(x{i} - 10)² = 25 x 3

∑(x{i} - 10)² = 75

Now, we can write that -

σ = √(75/3)

σ = √25

σ = 5

Therefore, the standard deviation of T is equivalent to 5.

Answer:

[tex]\frac{\pi}{6}[/tex] radian

Step-by-step explanation:

We are given that an angle in degrees

[tex]\theta=30^{\circ}[/tex]

We have to find the angle in radian measure as a multiple of π

To find the value of 30 degree in radian we will use the radian measure formula

We know that

Radian measure=[tex]\frac{\pi}{180}\times degree\;measure[/tex]

Using the formula

Radian measure of 30 degree=[tex]\frac{\pi}{180}\times 30[/tex]

Radian measure of 30 degree=[tex]\frac{\pi}{6}[/tex] radian

Hence, the radian measure of 30 degree is given by

[tex]\frac{\pi}{6}[/tex] radian

Answer:

x = 16

4x = 64

Step-by-step explanation:

The sum of the exterior angles of any polygon is 360°

Add the given angles and solve for x

93 + 46+ 3x + 62 + 4x +47 = 360

7x + 248 = 360

7x = 360 –248

x = 16
