So uh can someone answer this for me please i don’t understand it

Answer:

[tex]6\sqrt2\\OR\\8.48528137[/tex]

Step-by-step explanation:

The area of a sector of a circle is found by:

[tex]A = \frac{\theta*r^2}{2}[/tex]

The question asks for the radius so the equation above can be repurposed

[tex]r = \sqrt\frac{2A}{\theta}[/tex]

A = 3pi

angle = pi/12

[tex]\frac{6\pi}{\pi/12} = \frac{72\pi}{\pi} = 72[/tex]

[tex]\sqrt{72} = 6\sqrt2 = 8.48528137[/tex]

Answer:

1) 15.62 cm

2) 29.68 cm

Step-by-step explanation:

1) √(100 + 144) = √244 = 15.62 cm

2) √(256 + 625) = √881 = 29.68 cm

Answer:

Step-by-step explanation:

Answer:

85° and 95°

Step-by-step explanation:

Let's begin noting that a triangle is isosceles if and only if two of its angles are congruent. We can thus find the angle <ABP, recalling that the sum of the interior angles of a triangle is equal to 180°.

[tex] \angle \: ABP = \frac{180 - 80}{2} = 50 \degree[/tex]

Finally, let point K be the intersection between segments BC and PQ, and let's note that the triangle PQB is a right isosceles triangle, since all the angles in a square are equal to 90°, and the two triangles APB and BQC are congruent.

Therefore, the angle BKQ is equal to 180-50-45=85°.

Of course angle BKP=180-85=95°.

Hope this helps :)

Answer:

The point estimate of the proportion of women who trust recommendations made on Pinterest is of 0.78.

Step-by-step explanation:

To find the point estimate of the proportion of women who trust recommendations made on Pinterest, we find the sample proportion.

In this question:

150 women

117 trust recommendations made on Pinterest.

Point estimate:

[tex]p = \frac{117}{150} = 0.78[/tex]

The point estimate of the proportion of women who trust recommendations made on Pinterest is of 0.78.

Answer:

The null hypothesis is [tex]H_{0}: \mu = 8[/tex], and the alternative hypothesis is [tex]H_{a}: \mu < 8[/tex]

Step-by-step explanation:

At the null hypothesis, we test if the mean is equal to a certain value.

At the alternate hypothesis, we test if the mean is less than, more than, or different of the value tested at the null hypothesis.

Claims to lose an average of 8 pounds the first month

This means that the null hypothesis is [tex]H_{0}: \mu = 8[/tex]

If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising.

FTC tests if the mean is less than 8, so the alternate hypothesis is [tex]H_{a}: \mu < 8[/tex]

Answer:

The amount of people who are older than 70 is about 2                                  

Step-by-step explanation:

Answer:

I think it is 5/12 but might be wrong

Step-by-step explanation:

Subtracted 1/3 from 3/4

-5x + y = -3....A

3x - 8y = 24...B

Solve A for y.

-5x + y = -3

y = 5x - 3

Plug into B to solve for x

3x - 8(5x-3) = 24

3x -40x + 24 = 24

-37x = 24 - 24

-37x = 0

x = 0/-37

x = 0

Now that we know x, plug the value of x into A or B (your choice) to find y.

I will use B.

3x - 8y = 24

3(0) - 8y = 24

0 - 8y = 24

-8y = 24

y = 24/-8

y = -3

Answer: x = 0, y = -3

given:

-5x + y = -3

3x - 8y = 24

1st method

3x - 8y = 24

8y = 3x - 24

y = (3x - 24)/8

-5x + y = -3

-5x + (3x - 24)/8 = -3

(-40x + 3x - 24)/8 = -3

(-37x - 24)/8 = -3

(-37x - 24) = -3 × 8

-37x - 24 = -24

-37x = 24 - 24

-37x = 0

x = 0

2nd method

y - 5x = -3

y = 5x-3

3x - 8y = 24

3x - 8(5x-3) = 24

3x - 40x + 24 = 24

3x + 40x = 24 - 24

43x = 0

x = 0

Answer:

x² + 4x

Step-by-step explanation:

Area of the rectangle = length × width

length = x + 4

width = x

Therefore,

Area = x(x + 4)

Area = x*x + x*4

x² + 4x

Answer:

  3

Step-by-step explanation:

You can use your number sense to realize that 8/9 is between 3/4 and 1, so Tyrone can only get 3 whole pieces from his string.

__

If you like, you can do the division ...

  (8/9)/(1/4) = (8/9)(4/1) = 32/9 = 3 5/9 . . . . . 3 whole pieces

Or, you can compare decimal values.

  1 piece = 0.25 ft

  2 pieces = 0.50 ft

  3 pieces = 0.75 ft

  4 pieces = 1.00 ft

String length = 0.888.... ft (more than 3; less than 4 pieces)

Answer:

The answer is 126.

Step-by-step explanation:

If you multiply 2*9 first, you get 18. Then multiply 18 by 7. The answer will be 126. I hope this helps.

Answer:

12 remainder 3

Step-by-step explanation:

94- 7=87

87-7=80

80-7=73

73-7=66

66-7=59

59-7=52

52-7=45

45-7=38

38-7=31

31-7=24

24-7=17

17-7=10

10-7=3

We were able to subtract 7 from 94 12 while times! We ended up with a remainder of 3, our answer can be written as 12 R 3 or if you wnat it in decimal form its or 13.43

Answer:

Cos 2theta = -3/5

Step-by-step explanation:

Given that;

tan theta = -2

tan theta = -2/1 = opp/adj

hyp^2 = (-2)^2+1^2

hyp = √4+1

hyp = √5

sin theta = opp/hyp

sin theta = -2/√5

Cos theta = adj/hyp

Cos theta = -2/√5

Cos 2theta = 1-2sin^2 theta

Cos 2theta = 1- 2(-2/√5)^2

Cos 2theta = 1- 2(4/5)

Cos 2theta = 1- 8/5

Cos 2theta = (5-8)/5

Cos 2theta = -3/5

Answer:

The length of the other piece is 385 cm or 3 m 85 cm.

Step-by-step explanation:

Given that,

The length of the string = 6 m 50 cm

He cut it into 2 pieces.

Length of first piece = 265 cm

6 m 50 cm = 600 cm + 50 cm

= 650 cm

Length of another piece = 650 cm - 265 cm

= 385 cm

or

= 3 m 85 cm

So, the length of the other piece is 385 cm or 3 m 85 cm.

Answer:

  3) b; (C, S, T, T, S, C)

  4) Short, Tall, Medium

Step-by-step explanation:

3)

(a) Each odd-numbered item is "Circle", so the 18th item will be "Square"

(b) The 1st and 6th items are "Circle", and the sequence is 6 items long. The last item in the 3rd repetition will be the 18th item: "Circle". This rule gives the desired 18th item.

(c) "Circle" is the first of a 4-item sequence. The 18th item will be the second item in the 5th repetition, so will be "Triangle".

__

4) We presume the given 3 items are repeated, so the next 3 items will be the same: Short, Tall, Medium.
