Answer:

x = 7

Step-by-step explanation:

When two parallel lines are cut by a transversal, the corresponding angles are equal.

8x +2 = 7x + 9

Subtract 2 from both sides

8x = 7x + 9 - 2

8x = 7x + 7

Subtract 7x from both sides

8x - 7x = 7

x = 7

Answer:

x=7

Step-by-step explanation:

The 2 given angles are vertical to each other, so that means they are equal to each other.

To solve, set up an equation:

[tex]7x+9=8x+2[/tex]

Solve by isolating the variable. [Subtract and divide]

[tex]7x=8x-7[/tex]

[tex]-x=-7[/tex]

Multiply both sides by -1 to get rid of the negative sign.

[tex]x=7[/tex]

I hope this helps!

Step-by-step explanation:

Step-by-step explanation:

First, we may wonder, what does the term margin of error mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.

It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to increase the sample size of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.

Answer:

2 [tex]\frac{1}{3}[/tex] planes

Step-by-step explanation:

Set up a ratio.

planes over time.

Because the time is given in minutes. No conversion necessary.

[tex]\frac{planes}{time}[/tex] = [tex]\frac{3.5}{60}[/tex] = [tex]\frac{x}{40}[/tex]

Cross Multiply

60 (x) = 3.5 (40)

60x = 140      Divide by 60, both sides.

x = 2.333 repeating also know as 2 [tex]\frac{1}{3}[/tex].

Answer:

32/33

Step-by-step explanation:

We first need to find out how many square yards are vacuumed every one minute.

Let's set up a chart:

yards        minutes

8/11      -->    3/4

y          -->     1

Here, y is the number of yards it takes to vacuum in one minute. Next, we can use cross-multiplication to find out y.

1. Multiply 1 by 8/11 to get... 8/11

2. Multiply 3/4 by y to get... 3/4y

3. Equate them: 8/11 = 3/4y

4. Divide both sides of the equation by 3/4 OR multiply both sides of the equation by 4/3 to isolate y, the variable

5. This gives us 32/33 = y

Answer:

[tex]\boxed{\sf Distance_{AB}= 8.24 \ units }[/tex]

Step-by-step explanation:

Here two points are given to us and we need to find the distance between the two points . The given points are , A(0,0) and B(8,2) . The distance between the two points can be found out using the Distance Formula , which is ,

Distance Formula:-

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

Therefore on substituting the respective values ,we can find the Distance as ,

[tex]\sf\longrightarrow Distance = \sqrt{ ( 0 - 8)^2 + (0-2)^2} [/tex]

Simplify the brackets ,

[tex]\sf\longrightarrow Distance =\sqrt{ (-8)^2+(-2)^2}[/tex]

Square the numbers inside the squareroot ,

[tex]\sf\longrightarrow Distance =\sqrt{ 64 + 4} [/tex]

Add the numbers inside the squareroot ,

[tex]\sf\longrightarrow Distance = \sqrt{68} [/tex]

Find the value of squareroot,

[tex]\sf\longrightarrow \boxed{\blue{\sf Distance = 8.24 \ units }}[/tex]

Hence the distance between the two points is 8.24 units .

Answer:

Step-by-step explanation:

The domain includes all the "allowed" x values. Looking at the graph, it appears to start a tiny tiny bit to the right of 0, so it doesn't include 0. It also does not go to the left of 0. Therefore, the domain of the graph is x > 0

Answer:

[tex]x = 16[/tex]

Step-by-step explanation:

Step 1:  Add 79 to both sides

[tex]10x - 79 + 79 = 2x + 49 + 79[/tex]

[tex]10x = 2x + 128[/tex]

Step 2:  Subtract 2x from both sides

[tex]10x - 2x = 2x - 2x + 128[/tex]

[tex]8x = 128[/tex]

Step 3:  Divide 8 from both sides

[tex]\frac{8x}{8} = \frac{128}{8}[/tex]

[tex]x = 16[/tex]

Answer:

b = 74

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles in a triangle

b-44 + b+18 = b+48

2b-26 = b+48

Subtract b from each side

2b-b-26 =b+48-b

b-26 = 48

Add 26 to each side

b-26+26 = 48+26

b =74

Answer:

[tex] 3^{ -x+3}[/tex]

Step-by-step explanation:

We need to simplify out the given exponential expression . The given expression to us is ,

[tex]\rm\implies \dfrac{\dfrac{1}{3}}{3^{x-4}} [/tex]

We can use the Law of Exponents to simplify the given expression . Recall that ,

[tex]\rm\implies \red{\dfrac{a^m}{a^n}= a^{m-n}}[/tex]

Note that , we can write ,

[tex]\rm\implies \dfrac{1}{3}= 3^{-1}[/tex]

Therefore our expression becomes ,

[tex]\rm\implies \dfrac{ 3^{-1}}{3^{x-4}}[/tex]

Simpify using the Law of Exponents ,

[tex]\rm\implies 3^{ -1 - ( x - 4 )}[/tex]

Open the brackets in exponent ,

[tex]\rm\implies 3^{ -1 - x +4 }[/tex]

Simplify to get final expression ,

[tex]\rm\implies \boxed{\quad \blue{ 3^{-x+3} \quad}}[/tex]

Step-by-step explanation:

Answer:

The volume of the figure is 905 cubic units.

Step-by-step explanation:

Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.

volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

where r is the radius of the sphere.

Given that AB = 6, then the radius of the sphere = 6

volume of sphere = [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](6)^{3}[/tex]

                              = [tex]\frac{88}{21}[/tex] x 216

                              = 905.14

volume of sphere = 905 cubic units

The volume of the figure is 905 cubic units.

Answer:

A

Step-by-step explanation:

Answer A. Logically speaking there is no fair chance unless they use all the names but we can rule out C by the higher chance of students crowding, B is less likely as selecting winners from students who arrive first would be nearly the same as who bought their tickets first. D, selecting a grade excludes (estimating) around 1500 students or more from being included. A is the only logical answer left and by dividing them randomly you give everyone a full chance.
