The number of ways to select a chair person, a vice chairperson, a secretary, and a 4-person advisory committee is 303600 ways.

It should be noted that from the information, the engineering department of a large company has 25 members and the members must select a chair person, a vice chairperson, a secretary, and a 4-person advisory committee.

Therefore, the number of different ways that this can be done will be:

= 25P4

= 25! / (25 - 4)!

= 25! / 21!

= 25 × 24 × 23 × 22

= 303600 ways

The measure of the angle of the straight line is equal to 180 degrees. the measure of the ∠HLI and ∠ILM is equal to the which is 30 degrees. Thus option 4 is the correct option.

An endlessly long row of evenly spaced dots that spans in both directions makes up a line. Its length is the only dimension it has. A geometry called an angle is created when two line segments, lines, or rays intersect.

Given information-

The measure of the angle KLH is 120 degrees.

The image is attached below for the given problem.

The angle of the straight line

The measure of the angle of the straight line is equal to 180 degrees.

The line KLM is a straight line thus the angle of the line KLM is equal to 180 degrees.

The value of the angle ILH is 30 degrees given in the figure.

The value of the angle KLH is given in the question which is equal to 120 degrees. Thus,

∠KLM = ∠ILM + ∠KLH + ∠ILH

Take the angle KLH and the angle ILH on the other side,

∠ILM = ∠KLM - ∠KLH - ∠ILH

∠ILM = 180 - 120 - 30

∠ILM = 30

Thus the measure of the is 30 degrees.

As the measure of the is equal to the which is 30 degrees. Thus option 4 is the correct option.

Step-by-step explanation:

:)

Step-by-step explanation:

the area of any triangle is

baseline × height / 2

so, in our case

12 × height / 2 = 48

6 × height = 48

height = 48/6 = 8 units

m with the height and half of the baseline creates a right-angled triangle. and we can use Pythagoras to get m.

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle), which is m for this right-angled triangle.

a and b are the legs, which are in our case the height of the main triangle and half of the baseline of the main triangle.

so we get

m² = 8² + (12/2)² = 8² + 6² = 64 + 36 = 100

m = 10 units

By using the concepts of line segment and collinearity of line segments, the numerical length of the line segment JK within the line segment IK is 21 units.

In this problem we find two collinear line segments IJ and JK, two line segments are collinear if they are contained by the same line. The mathematical expression that represents the two collinear line segments are shown below:

IJ + JK = IK

If we know that JK = x + 6, IJ = 9 and IK = 2 · x, then the numerical length of JK is:

9 + (x + 6) = 2 · x

x + 15 = 2 · x

15 = 2 · x - x

15 = x

x = 15

JK = x + 6

JK = 15 + 6

JK = 21

Given that, the translation is 3 units right and 4 units down.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving the shape from one place to other, there is no change in the shape.

The coordinates of the given figure are R(-3, 0), S(-1, 4), T(0, 4) and U(1, 3).

If the translation is 3 units right and 4 units down, then the coordinates become (x+3, y-4).

That is, R'(-3+3, 0-4)=(0, -4)

S'(-1+3, 4-4)=S'(2, 0)

T'(0+3, 4-4)=T'(3, 0)

U'(1+3, 3-4)=U' (4, -1)

So, the coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1)

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

======================================================

Explanation:

Part (a)

Pick any two points on line p. I'll go for points A and V. They lead to the name "line AV". The order doesn't matter so we could say "line VA"

Or you could pick points A and R to get line AR, and so on.

There are 6 different ways to name this line. We found 2 so far, and I'll let you find the other four.

-------------------------------

Part (b)

To name a plane, we need 3 points that reside in it. Points R, S and Z are in the vertical plane W. So we could call it "Plane SRZ". The order of the points doesn't matter.

-------------------------------

Part (c)

The term "collinear" means the points are on the same straight line. This applies to points S, R and Q. Also, it applies to points A, R, and V.

We cannot say something like "points S, R, and V are collinear" since they are on different lines. The points need to be on the same straight line.

-------------------------------

Part (d)

Coplanar points are part of the same plane. Pick your four favorite points in plane W that is shaded. You cannot select W since it's not a point.

-------------------------------

Part (e)

A line segment has a fixed length. Neither endpoint goes on forever. Technically there aren't any segments shown on this diagram since we have lines only. Though if we focus on a subset of say line AV, then segment RV is one possible line segment.

-------------------------------

Part (f)

Like with part (e), there are technically only lines here and nothing else. But we could break the line apart to get 2 rays.

A ray has one fixed endpoint and it points forever in one direction only. Think of a ray of light. An example of a ray is to start at point R and go forever toward point V. This forms ray RV. A similar situation happens with ray RA.

The order is important. The notation Ray RV is different from Ray VR since the first letter tells us the fixed endpoint that doesn't go on forever.

Notice how rays RV and RA, when joined together, form a straight line. They point in opposite directions. You could think of it like one is pointing north and the other points south.

Answer:

[tex]\textsf{a.} \quad \overleftrightarrow{AV} \; \textsf{and} \; \overleftrightarrow{RV}[/tex]

[tex]\textsf{b.} \quad STZ, \; RTZ, \;QTZ[/tex]

[tex]\textsf{e.} \quad \overline{AR}[/tex]

[tex]\textsf{f.} \quad \overrightarrow{RA} \; \textsf{and} \; \overrightarrow{RV}[/tex]

Step-by-step explanation:

A line can be named by using two points on the line or by a (lowercase) letter.

Therefore, two other names for line p are:

A plane can be named by using three non-collinear points in the plane or by a (capital script) letter.

Therefore, three other names for plane W are:

Collinear points are points that lie on the same line.

The collinear points on the given diagram are: A, R & V, and S, R & Q.

Therefore, three points that are collinear are:

Coplanar points are three or more points that lie in the same plane.

The coplanar points on the given diagram are: Q, R, S, T and Z

Therefore, four points that are coplanar are:

A line segment is part of a line that has two endpoints, and is named by its two endpoints.

The line segments on the given diagram are:

Therefore, a line segment is:

A ray is a part of a line that has one endpoint (so continues infinitely in the direction without an endpoint).  

Opposite rays are two rays that have a common endpoint and form a line.  They are named by the common endpoint followed by any other point on each ray.

The pairs of opposite rays on the given diagram are:

[tex]\overrightarrow{RA} \; \textsf{and} \; \overrightarrow{RV}, \quad \overrightarrow{RS} \; \textsf{and} \; \overrightarrow{RQ}[/tex]

Therefore, a pair of opposite rays are:

Answer:

Step-by-step explanation:

Multiply to move the decimal, therefore giving you a whole number.

Answer:

AB and CD are congruent.

Step-by-step explanation:

Given points:

After plotting the given points (see attachment), we can easily determine that AB is 7 units and CD is 7 units.  Therefore, AB and CD are congruent.

Alternatively, as points A and B share the same x-coordinate, the length of AB is the difference between the y-coordinates:

⇒ AB = 8 - 1 = 7 units

Similarly, as points C and D share the same y-coordinate, the length of CD is the difference between the x-coordinates:

⇒ CD = 5 - (-2) = 7 units

Finally, we can prove that AB and CD are congruent by calculating their lengths using the distance formula.

[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}\implies AB & =\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& =\sqrt{(-4-(-4))^2+(8-1)^2}\\& =\sqrt{(0)^2+(7)^2}\\& =\sqrt{0+49}\\& =\sqrt{49}\\& =7\end{aligned}[/tex]

[tex]\begin{aligned}\implies CD & =\sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\ & =\sqrt{(5-(-2))^2+(-5-(-5))^2}\\ & =\sqrt{(7)^2+(0)^2}\\ & =\sqrt{49+0}\\ & =\sqrt{49}\\ & =7\end{aligned}[/tex]

Therefore, as AB = CD, this proves that AB and CD are congruent.
