Q = 2D

Q = 4N

N = ??

Q + D + N = 2.50

(4N) + (2N) + N = 2.50

Answer:

9

Step-by-step explanation:

Mean = sum of number / total number

6 = (2 + x + 2 + 7 + 4 + 12) / 6

Multiply both sides by 6

36 = 27 + x

Solve for x

x = 36 - 27 = 9

Answer:

2160°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 14, so

sum = 180° × 12 = 2160°

Answer:

30

Step-by-step explanation:

area of triangle =1/2×sino×25×16

100=200sino

100/200=sino

sino=1/2

sino=sin30

o=30°

Here is the complete question.

[tex]Consider \ circle \ Y \ with \ radius \ 3 m \ and \ central \ angle \ XYZ \ measuring \ 70°. \\ \\ What \ is \ the \ approximate \ length \ of \ minor \ arc \ XZ?\\ \\ Round \ to \ the \ nearest \ tenth \ of \ a \ meter. \\ 1.8 meters \\ 3.7 \ meters \\ 15.2\ meters \\ 18.8 \ meters[/tex]

Answer:

3.7 meters

Step-by-step explanation:

From the given information:

The radius is 3m

The central angle XYZ = 70°

To calculate the circumference of the circle:

C = 2 π r

C = 2 × 3.142 × 3

C = 18.852 m

Let's recall that:

The circumference length define a central angle of 360°

The approximate length of minor arc XZ can be determined as follow:

Suppose the ≅ length of minor arc XZ = Y

By applying proportion;

[tex]\dfrac{18.852}{360} = \dfrac{Y}{70}[/tex]

Y(360) = 18.852 × 70

Y = 1319.64/360

Y = 3.66

Y ≅ 3.7 m

Answer:

s=40

Step-by-step explanation:

Combine s and 1/2.

150−s/2=120+1/4s

Combine 1/4and s.

150−s/2=120+s/4

Move all terms containing s to the left side of the equation.

150−3s/4=120

Move all terms not containing s to the right side of the equation.

−3s/4=−30

Multiply both sides of the equation by −4/3.

−4/3 x (−3s/4)=−4/3 x−30 => S=40

Answer:

40

Step-by-step explanation:

First, get all the s on the same side

add 1/2s to both sides

[tex]150 = 120 + \frac{3}{4}s[/tex]

Next, subtract 120 from both sides to get s by itself

[tex]30 = \frac{3}{4}s[/tex]

Now, multiply both sides by 4 to get rid of the fraction

120 = 3s

Lastly, divide both sides by 3 to get s by itself

s = 40

Using a proportional relationship, the graph of the proportional relationship [tex]y = -2.1x[/tex] is sketched at the end of this answer.

"y varies directly with x", hence, the equation is modeled by:

[tex]y = ax[/tex]

y = -8.4 when x = 4, hence, we can use it to find a.

[tex]-8.4 = 4a[/tex]

[tex]a = -\frac{8.4}{4}[/tex]

[tex]a = -2.1[/tex]

Hence, the equation is:

[tex]y = -2.1x[/tex]

The graph is sketched at the end of this answer.

Answer:

y=17

Step-by-step explanation:

We move all terms to the left:

23-(y+40.)=0

We add all the numbers together, and all the variables

-(y+40)+23=0

We get rid of parentheses

-y-40+23=0

We add all the numbers together, and all the variables

-1y-17=0

We move all terms containing y to the left, all other terms to the right

-y=17

y=17/-1

y=-17

Answer:

C = (3, -3), D = (-2, -3)

Step-by-step explanation:

The distance between two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is given by:

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Points ABCD form a rectangle with an area of 30 unit². Points A and B are located at A(-2, 3) and B(3, 3). The distance between A and B is:

[tex]|AB|=\sqrt{(3-(-2))^2+(3-3)^2}=5\ units[/tex]

|AB| = width = 5 units

Area of ABCD = |AB| * |BC|

30 = 5 * |BC|

|BC| = length = 6 units

Let point C be located at (c, d). Since point C is below point B, hence the c coordinate of point B would be the same as that of C. Hence C = (3, d)

[tex]|BC|=\sqrt{(3-3)^2+(d-3)^2} \\\\\sqrt{0+(d-3)^2}=6\\\\square\ both\ sides:\\\\(d-3) ^2=36\\\\take\ square\ root\ of\ both\ sides:\\\\d-3=\pm 6\\\\d=6+3\ or\ d=-6+3\\\\d=9\ or\ d=-3\\\\[/tex]

Since point C is vertically below point B, hence the y coordinate would be negative

d = -3

C = (3, -3)

Point D would have the same y coordinate as point C since they are on the same horizontal line. Also, point D would have the same x coordinate as point A since it is vertically below point A. Hence:

D = (-2, -3)
