Find X So That L || M. Show Your Work.

Answers

Answer 1

Answer:

x = 22

Step-by-step explanation:

If l and m are parallel, then

(2x + 60) and 130° are same- side interior angles and are supplementary, thus

2x + 6 + 130 = 180 , simplify

2x + 136 = 180 ( subtract 136 from both sides )

2x = 44 ( divide both sides by 2 )

x = 22

Using the diagram above, what is the measure of ∠KPN?

Answers

Answer:

∠KPN = 62°

Step-by-step explanation:

If you look at ∠KPO, you can see that it equals 90°

Therefore, ∠KPN and ∠NPO add up to 90°

1. Add both expressions

2x + x- 3 = 90

3x - 3 = 90

2. Add 3 to the 90 to isolate variable x

3x = 93

3. Divide both sides by 3

x = 31

4. Plug in the value for x (31) into ∠KPN

2(31) = 62°

Use the side-splitter theorem to solve for x in the triangle below.

Answers

Answer:

[tex] x = 7 [/tex]

Step-by-step explanation:

According to the side-splitter theorem, the two sides of the triangle is divided proportionally if the line that intersects both sides is parallel to the third side of the ∆.

Therefore, based on this theorem, we would have the following:

[tex] \frac{x}{21} = \frac{8}{24} [/tex]

Solve for x

[tex] \frac{x}{21} = \frac{1}{3} [/tex]

Multiply both sides by 21

[tex] \frac{x}{21}*21 = \frac{1}{3}*21 [/tex]

[tex] x = \frac{21}{3} [/tex]

[tex] x = 7 [/tex]

A 0.450 L sample of nitrogen gas is collected under a pressure of 2.30 atm and a temperature of 60.0 degrees Celsius. The sample is transferred to a 0.600 L container and the pressure drops to 1.54 atm. What is the new temperature of this gas (in K)?

Answers

Answer:

326.56K

Step-by-step explanation:

Step one:

Given

V1=0.45L

P1=2.3atm

T1=60 °

V2=0.6L

P2=1.54atm

T2=?

Step two:

Required:

T2

Applying the partial gas formula

[tex]\frac{P1V1}{T1}=\frac{P2V2}{T2}[/tex]

[tex]\frac{2.3*0.45}{60}=\frac{1.54*0.6}{T2}[/tex]

cross multiply we have

T2=(1.54*0.6*60)/2.3*0.45

T2=55.44/1.035

T2=53.56 °

in kelvin, we need to add 273

=273+53.56=326.56K

T2=326.56K

The new temperature of this gas (in K) is 326.56K

Answers

Answer:

First graph's equation is: y=2/3x+3

Second graph's equation is: y=2/3x-1

Third graph's equation is: y=2/3x+1

Fourth graph's equation is: y=2/3x-3

Step-by-step explanation:

Well you didn't provide the equation so I can't give you the exact answer but I can tell you the equation for each graph and you can match that with the equation they gave you!

Here ya go:

The y intercept is where the line crosses the y axis(vertical axis)

The slope is rise/run (vertical/horizontal)

The first graph:

The line crosses the y axis at (0, 3)

To find the slope we need to take the (y) of one of the given coordinates and subtract the (y) of the other coordinate then divide that over (x) of one of the coordinates minus the (x) of the other coordinate.

5-1/3-(-3)

4/6

2/3 is our slope, apply that to slope-intercept formula (y=mx+b)

y=2/3x+3

The second graph:

The line crosses the y axis at (0, -1)

Do as we did with the first graph to find the slope.

1-(-3)/3-(-3)

4/6

2/3 is our slope

y=2/3x-1

The third graph:

The line crosses the y axis at (0, 1)

Find the slope

3-(-1)/3-(-3)

4/6

2/3 is our slope

y=2/3x+1

The fourth graph:

The line crosses the y axis at (0, -3)

Find the slope
