There are numerous videos and web sites that can show you the process of copying an angle. Some are animated. The best we can do here is show you a diagram with instructions. Of course, your curriculum materials already provide that

__

1. Set the compass to a convenient radius. Use that to draw an arc through rays ED and EF, using point E as the center.

2. Without changing the compass setting, draw a similar arc using S as the center, making sure it crosses the line containing S and extends far enough to accommodate the following steps. (In the attached, we show a full circle, because the tool we used won't draw an arc with a specific radius.)

3. Mark the points where the arc crosses ED as G, and where it crosses EF as H. Mark the point where the arc crosses the line containing S as I.

4. Set the compass radius to the distance GH. Using I as the center draw an arc with that radius so that it crosses the one made in step 2. Call that intersection point J. (Again, we have shown a circle because of the limitations of the tool being used for our diagram.)

5. Draw ray SJ to complete the angle copy.

Answer:

30 c + 100 m = 700

c+ m = 14

Step-by-step explanation:

The product of the number of movies where the song was played (m) multiplied by the earnings per movie (30) plus the product of the number of commercials where the song was played (m) multiplied by the earnings per commercial, must be equal to $700.

30 c + 100 m = 700

The number of movies (m) plus the number of commercials (c) is equal to 14.

c+ m = 14

The system is:

30 c + 100 m = 700

c+ m = 14

The solution to start fraction x over negative 6 end fraction = 10 is -60.

Here the equation will be

x/-6 = 10

We have to solve for the value of x. So, in order to solve for the value of x we simply have to multiply -6 by the RHS of the equation i.e., 10.

⇒x = -6x10

⇒x = -60

Therefore, the solution to start fraction x over negative 6 end fraction = 10 is -60.

This can sometimes result in 2 possible values when using the Law of Sines, since sin(180°-x)=sin(x)

C.It is zero.

The net force is the sum of all of the forces exerted on an object.

Identifying Forces

Force is measured in newtons, which is shortened to N. Additionally, force will always have a direction, like 5N up or 3N to the left.

Sometimes force will be negative to represent direction. A force moving down or to the left might be negative because moving down or to the left on an axis moves towards negative numbers.

Net Force

As stated above, the net force is the sum of all of the forces acting on an object. For example, if one object is being moved 5N to the left and 4N to the right, the net force will be 1N to the left.

On the other hand, if the forces are balanced, like 5N on both the left and right, then the forces cancel out. This leaves a net force of 0.

The midpoint of diagonal AC is (5,-3).

Given A(3,-1) and C(7,-5)

Let the midpoint of diagonal AC be represented by P (say). Then the coordinate of P can be calculated by using the formula listed below:

let us suppose the coordinates of A be (a, b) and B be (c, d) and P is the midpoint of AC then the coordinate of P will be (a+c/2, b+d/2).

Now, by using the above formula, we get

x-coordinate of P be (3+7)/2 = 10/2 = 5

y-coordinate of P be (-1+(-5))/2 = -6/2 = -3

If a long run athlete can run 1/2 km in 3 minutes then he can run 10 km in an hour.

Given, a long distance athlete can run 1/2 kilometer in 3 minutes.

How much distance can he cover in an hour = ?

How quickly something or someone is moving is determined by their speed. If you know how far an object has traveled and how long it has taken, you can calculate its average speed. Speed equals distance times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.

Time = 60 minutes.

we know that 3 minutes = 1/2 km

therefore, distance covered in an hour = 1/2 ÷ 3/60

= 1/2 × 60/3

= 1/2 × 20

= 10

distance covered in an hour = 10 km.

hence we get the distance covered by the athlete in an hour as 10 km.

The expected raise a union wage negotiator feels that   the union members will get is $1.22.

The probability of each pay raise is given below

P ($1.50 raise) = 0.40

P ($1.00 raise) = 0.30

P ($0.50 raise) = 0.20

P (no raise) = 0.10

The probability of each pay raise is then multiplied by the pay itself

Expected raise for each hour = $1.50(0.40) + $1.00(0.30) + $0.50(0.20) + $0.00(0.10)

E(x) = 0.6 + 0.52 + 0.1 + 0 (The probability of no pay at all gives 0 since the pay amount has no value)

E(x) = $1.22

               The value of the star = 7

               The value of the rhombus = 18.

               The value of the circle  = 4,

               The value of the right angle triangle  = -5

Step-by-step explanation:

Define Linear equation:

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.

An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Given that,

Let us assume the values is,

(Option 1) : A shape puzzle is given that,

Let's assume, the triangle shape represents = a

Let's assume, the square shape represents = b

Let's assume, the star shape represents = c

The equation becomes,

clue 1 : 2a-1 = 5

clue 2 : a + b = 1

clue 3 : a-2b = c

First take, clue 1 :         2a-1 = 5

                                       2a = 5+1

                                        2a = 6

                                         a = 6/2

                                          a = 3

Therefore,       triangle (a) = 3

Take, clue 2 :                      a + b = 1

Replace 'a' value in this equation,

                                            a + b = 1

                                            3+b = 1

                                              b = 1-3

                                              b = -2

 Therefore,         square (b) = -2

Take clue 3 :                     a-2b = c

Replace with 'a' and 'b' values in this equation,

                                          a-2b = c

                                           3-2(-2) = c

                                            3+4 = c

                                              c = 7

Therefore,             star (c) = 7

we can substitute these values,

Then,      clue 1 : 2(3) -1 = 6-1 = 5

               clue 2 : 3 + (-2) = 3-2 = 1

               clue 3 : 3-2(-2) = 3+4 = 7

Thus, The value of the triangle = 3.

         The value of the square is = -2,

          The value of the star = 7

after using the concept of linear equation in two variables.

(Option 2) : A shape puzzle is given that,

Let's assume, the rhombus shape represents = x

Let's assume, the circle shape represents = y

Let's assume, the right angle triangle shape represents = z

The equation becomes,

clue 1 : x+2 = 5y

clue 2 : 3y = 12

clue 3 : 2y = x+2z

Take, clue 2 :                     3y = 12

                                            y = 12/3 = 4

Therefore,      circle (y) = 4

First take, clue 1 :         x+2 = 5y

                                      x+2=5(4)

                                      x+2=20

                                      x = 20-2 = 18

Therefore,       rhombus (x) = 18

Take clue 3 :                      2y = x+2z                

Replace with 'x' and 'y' values in this equation,

                                         2y = x+2z

                                         2(4) = (18)+2z

                                          2(4) = (18)+2z

                                           8 = (18)+2z

                                            8-18 = 2z

                                             -10 = 2z

                                              z = -10/2

                                              z = -5

Therefore,         right angle triangle (z) = -5

we can substitute these values,

Then,      clue 1 : 18+2=5(4)

                            20 = 20

               clue 2 : 3(4) = 12

                             12 = 12

               clue 3 : 2(4) = 18+2(-5)

                             8 = 18-10

                             10+8 = 18

                              18 = 18  

Thus, The value of the rhombus = 18.

         The value of the circle  = 4,

          The value of the right angle triangle  = -5

after using the concept of linear equation in two variables.
