At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.

(a) Write and simplify an expression for the exact area of the sidewalk.
(b) Find the approximate area of the sidewalk. Use 3.14 to approximate π.

Answer:

[tex]VYX=84.3in[/tex]

Step-by-step explanation:

Given

[tex]YV = 28in[/tex]

[tex]\angle WZX = 15^\circ[/tex]

See attachment

Required

Determine the length of [tex]VYX[/tex]

First, calculate the major angle VZX

[tex]\theta = \angle VZX = 360 - \angle WZX[/tex]

[tex]\theta = \angle VZX = 360 - 15[/tex]

[tex]\theta = \angle VZX = 345[/tex]

[tex]\theta = 345[/tex]

The length of arc VYX, is:

[tex]L=\frac{\theta}{360} * 2\pi r[/tex]

Where

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * YV[/tex]

[tex]r = \frac{1}{2} * 28[/tex]

[tex]r = 14[/tex]

So:

[tex]L=\frac{\theta}{360} * 2\pi r[/tex]

[tex]L=\frac{345}{360} * 2 * \frac{22}{7} *14[/tex]

[tex]L=\frac{345}{360} * 2 * 22 *2[/tex]

[tex]L=\frac{345* 2 * 22 *2}{360}[/tex]

[tex]L=\frac{30360}{360}[/tex]

[tex]L=84.3in[/tex]

Hence, the length of VYX is:

[tex]VYX=84.3in[/tex]

Answer:

El resultado eres: [tex]R(x) + S(x) = -6x^2 - 2x - 2[/tex]

Step-by-step explanation:

Se dan las siguientes funciones

[tex]R(x) = -5x^2 + x - 2[/tex]

[tex]S(x) = -x^2 - 3x[/tex]

Cuál es el resultado de R(x) + S(x) ?​

Se soman los fatores en comun. Entonces:

[tex]R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2[/tex]

El resultado eres: [tex]R(x) + S(x) = -6x^2 - 2x - 2[/tex]

Answer:

k = 140 degrees.

The missing INTERIOR angle is 40 degrees.

Step-by-step explanation:

The missing interior angle would be 40.

Triangle angle sum theorem states the 3 interior angles of a triangle sum to 180.

64+76+40 = 180

The exterior angle theorem states the exterior angle of a triangle is equal to the sum of the two remote interior angles of the triangle.

Exterior angle k = 64+76

k= 140

Step-by-step explanation:

Going off the graph I was given, there was a peak at 2. There are no outliers. The data is also not symmetrical.

Answer:

274

Step-by-step explanation:

Hey There!

So if you didnt know the median is the middle number ( in value) of the set

So first we would like to arrange the numbers in order from least to greatest

187 , 199 , 211 , 250 , 298 , 331 , 347 , 362

Then we take the middle number(s)

if there is just one then that is the answer but if there is two than we add them together and divide that by 2

In this case there are two which would be 250 and 298

So we add them together

250+298=548

Then we just divide that by 2

[tex]\frac{548}{2} =274[/tex]

Therefore the median is 274

Step-by-step explanation:

It is 1200 increased by 13%

Answer:

hindi ko po maintin dihan sorryyyyyyyyyy

Answer:

9/11 = 45/55

4/5 = 44/55

Obviously, 45 is more than 44, so 9/11 is greater than 4/5.

Answer:

8p

Step-by-step explanation:

8 • p = 8p

Answer:

a) Yes

Step-by-step explanation:

Because, 3+7=10

Answer: yes

Explanation: In this problem, to determine whether c = 3

is a solution to the equation, we substitute 3 in for c.

So we have (3) + 7 = 10.

Simplifying the left side of the equation, (3) + 7 is 10.

So we have 10 = 10 which is a true statement so our answer is yes.

Hey there!

The mean would probably best represent the data.

This is because the mean of data is the average, which would show what the average temperature throughout the week was.

Answer:

Ratio of the area of MIKE to TEAM = 9 : 1

Step-by-step explanation:

Ratio of similar shapes = square of the ratio of their corresponding sides

Since TEAM ~ MIKE, therefore the ratio of their areas = square of the height of MIKE : square of the height of TEAM

Ratio = 33² : 11²

Ratio = 1089 : 121

Ratio = 9 : 1

Answer:

it is 15,000

Step-by-step explanation:

15,000 because there is 1,000 milliliters in one liters and 15 liters = 15,000 milliliters

Answer:

3/8

Step-by-step explanation:

3/8 of 16 is 6

1/4 of 16 is 4

6+4 = 10

16-10 = 6

3/8 of 16 = 6

Answer:

1,728cm squared  

Step-by-step explanation:

1. Break the Composite Figure into smaller shapes such as, rectangles, triangles, and squares.

2. Use the area formula for rectangles, triangles, and squares to find the area of each smaller shape.

3. Add the area of the smaller shapes together to get the area of the entire Composite Figure.

Hope this is correct and helps :[]).
