Answer:

[tex]143.8\:\mathrm{ft^2}[/tex]

Step-by-step explanation:

The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:

Area of semi-circle (half the area of a circle): [tex]\frac{1}{2}\cdot 4.5^2\cdot \pi[/tex]

Area of trapezoid (average of bases multiplied by height): [tex]16\cdot 7[/tex]

Thus, the total area of the figure is:

[tex]\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}[/tex]

Answers

Answer:

A= 30

Step-by-step explanation:

This requires several steps.

First, you need to find the 2 other missing angles.

One can be found easily by substracting 130 from 180

so 180-130 = 50

The other angle is the same as 8x+4

Now set up your equation

180=3x-6 + 8x+4 +50

180 = 3x + 8x -6 + 4 +50

180+6-4-50 = 11x

132 = 11x

132/11 = x

12 = x

Now plug in 12 for x in your angle A

A=3x-6

A=3 * 12 - 6

A=36 - 6

A= 30

Find the length of AB.

S = 15.47 units

Step-by-step explanation:

First, convert the degree angle into radians:

68° × (π/180) = 1.19 rad = theta

The arc length S is given by

S = r × theta

= (13 units)(1.19 rad)

= 15.47 units

Answer:

15.43

Step-by-step explanation:

The formula = angle / 360 × circumference

= angle / 360 × pi diameter

= 68 / 360 × pi × 13 + 13

= 68 / 360 × pi × 26

= 17 / 19 × pi × 26

= 221 / 45 pi

= 15.43

A laundry basket contains 8 white t-shirts and 6 black t-shirts. What is the probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back?

Answers

Answer:

30/182 = 15/91.

Step-by-step explanation:

PROBABILITY: the likelihood of an event.

There are a total of 14 shirts in the basket.

Of the 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.

The probability of picking a black shirt is 6 in 14, or 6/14.

The probability of picking a white shirt is 8 in 14, or 8/14.

WITHOUT REPLACING: This means that you take one without putting it back. (There will be one less).

6/14 × 5/13 = 30/182.

30/182 = 15/91.

The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back is 15/ 91.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

There are a total 14 shirts in the basket.

Out of the total of 14, 8 (8/14) of them are white, and 6 (6/14) of them are black.

The probability of picking a black shirt = 6/14.

The probability of picking a white shirt = 8/14.

The probability of randomly picking a black t-shirt from the basket, and then another one without putting the first one back

= 6/14 × 5/13

= 30/182.

= 15/91.

hope this helps! :)

Here is how you would solve this system of equations.

[tex]\begin{bmatrix}4x+2y=10\\ x-y=13\end{bmatrix}[/tex]

Step 1: Multiply x-y=13 by 4.

[tex]\begin{bmatrix}4x+2y=10\\ 4x-4y=52\end{bmatrix}[/tex]

Step 2: Subtract the equations.

[tex]4x-4y=52[/tex]

-

[tex]\underline{4x+2y=10}[/tex]

[tex]-6y=42[/tex]

[tex]\begin{bmatrix}4x+2y=10\\ -6y=42\end{bmatrix}[/tex]

Step 3: Solve -6y=42

[tex]y=-7[/tex]

For 4x+2y=10 plug in y=-7

[tex]4x+2(-7)=10[/tex]

Simplify.

[tex]4x-14=10\\4x-14+14=10+14\\4x=24\\x=6[/tex]

Therefore, x=6, y=-7.

Hope this helps.
