PLEASE HURRY AND HELP

Answer:

C.

Step-by-step explanation:

Radius = 16 ÷ 2 = 8

[tex]\frac{45}{360} *8^2*\pi =25.1[/tex] (3sf)

You can first find the total area of the circle which is [tex]64\pi[/tex].

Then, you can find the area of the slice of the pizza, if you take the ratio of the angle it creates with the total angle of a circle (360.)

For example, a semicircle's are would be  [tex]\frac{180}{360} *8*\pi[/tex].

Answer:

3/50

Step-by-step explanation:

Slope m = y2-y1/x2-x1

From the coordinate

x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5

Substitute;

m = (3/5 - 2/3)/-4/9-2/3

m = (9-10/15)/(-4-6/9)

m = -1/15/-10/9

m = -1/15 * -9/10

m = 9/150

m = 3/50

Hence the slope of the line passing through the points is 3/50

Answer:

n = (7/3)t

Step-by-step explanation:

Represente the unknown number by n.  Then write the statement symbolically, as:

(3/7)n = t

and then solve the above equation for n by multiplying both sides by (7/3):

n = (7/3)t

Answer:

40,320 different ways

Step-by-step explanation:

Here, we want to arrange 8 flags in a row

In the row, there will be 8 places

The first place has 8 flags to be chosen from

The second place has 7 and like that

So mathematically, the number of ways that we can arrange the flags is 8 factorial ways

We have this as:

8! = 40,320 different ways

Answer:

x = 9

Step-by-step explanation:

What we have here is a bisected angle. What this means is that an angle is being cut in half to create multiple angles. In this case angle E has been bisected. Since that is the case, angles 1 and 2 are equivalent to each other. Now that we know this we can solve for x.

Equation:

x + 8 = 2x - 1

8 = x - 1

9 = x

Answer:

s= 96

Step-by-step explanation:

s°= 48° +48° (ext. ∠ of triangle)

s°= 96°

s= 96

☆ Exterior angle of a triangle

- The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

Answer:

A) 18°

Step-by-step explanation:

To find the measure of the indicated angle, we can use trigonometric ratios.

Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:

[tex]tan(?)=\frac{opposite}{adjacent}[/tex]

From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:

[tex]tan(?)=\frac{3}{9}[/tex]

Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:

[tex]?=tan^{-1}(\frac{3}{9})[/tex]

And we get:

? ≈ 18.4349488° ≈ 18°

So the answer would be 18°, or A.

I hope you find my answer to be helpful. Happy studying.

Answer:

x = 8

Step-by-step explanation:

the sum of all three interior angles in any triangle = 180°

42° + 8x + 14° + 60° = 180°

8x = 180° - 42° - 14° - 60° = 64°

x = 8

Answer:

y = 2

Step-by-step explanation:

-13y + 33 = 7

add -13y to each side of the equation:

33 = 13y + 7

subtract 7 from each side:

13y = 26

divide both sides by 13:

y = 2

Answer:

A square is defined as a quadrilateral with 4 sides of the same length and 4 right angles. To verify the lengths of the sides, you can use the distance formula. To find the angles, you can use the slopes of the line segments and make sure sides that form an angle have opposite reciprocal slopes.

Step-by-step explanation:

First, find the coordinates of each point. You're provided with the scale and you can just count, but to make it easier, you can label the axes.

A: (0,8)

B: (6,6)

C: (4,0)

D: (-2,2)

The distance formula is used to find the distance between any two points on the coordinate form. Here it is:

d=sqrt((y2-y1)^2 + (x2-x1)^2)

d=distance, and (x1, y1) and (x2, y2) are the points.

Find the length of each side. I'll demonstrate with two sides, AB and BC.

AB: (x1,y1)=(0,8) and (x2,y2)=(6,6)

d=sqrt((6-8)^2 + (6-0)^2)

 =sqrt((-2)^2 + 6^2)

 =sqrt(4+36)

 =sqrt(40)=2sqrt10

BC: (x1,y1)=(6,6) and (x2,y2)=(4,0)

d=sqrt((4-6)^2 + (0-6)^2)

 =sqrt((-2)^2 + (-6)^2)

 =sqrt(4+36)

 =sqrt(40)=2sqrt10

Do the same thing with sides CD and AD, you'll see that they both also have a length of 2sqrt10 inches. (You don't really have to simplify, I just like to.)

To verify if the sides are perpendicular, you need to find the slopes of the sides and make sure that the product of the slopes of each pair of sides that form a vertex is -1. In other words, each pair of sides that form a vertex have to have opposite reciprocal slopes. I'll demonstrate with 2 vertecies, A and B.

To find the slope, you have to use the formula m=(y2-y1)/(x2-x1). m is the slope, and again, (x1, y1) and (x2, y2) are the points you're plugging in.

To find the measure of angle A, you need to find the slopes of sides AD and AB. (These are the sides that meet to form the angle.)

AD: (x1,y1)=(0,8) and (x2,y2)=(-2,2)

m = (2 - 8)/(-2 - 0)

   = -6/-2

   = 3

AB: (x1,y1)=(0,8) and (x2,y2)=(6,6)

m = (6 - 8)/(6 - 0)

   = -2/6

   = -1/3

So AD has a slope of 3 and AB has a slope of -1/3. Now you need to make sure they have a product of -1.

-1/3 * 3 = -1

So yes, it works! As I mentioned before, you can also think of them as opposite reciprocals.

The reciprocal of 3 is 1/3. The opposite of 1/3 is -1/3. So yes, the sides are perpendicular.

Let's do it again with angle B. We have to find the slope of BC now, since we already know the slope of AB.

BC: (x1,y1)=(6,6) and (x2,y2)=(4,0)

m = (0 - 6)/(4-6)

   = -6/-2

   =3

So the slope is exactly the same as the slope of AD. A square is a parallelogram, so it has two pairs of opposite parallel sides. We already verified that 3 and -1/3 are opposite reciprocals, so we now know that angle B has a measure of 90 degrees as well. You can do the same for angles C and D. That way, you'll have proven that all the sides have the same length and all the angles measure 90 degrees-- so the quadrilateral ABCD matches the definition of a square.

Hope this helped!
