Use the side-splitter theorem to solve for x in the triangle below.
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]
Using the diagram above, what is the measure of ∠KPN?
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°

Find the area of the shape shown below.
Step-by-step explanation:
There are 4 shapes shown in figure i.e Rectangle, Triangle two times and a square .
Dimensions of rectangle length = 9
Breadth = 5
Square = 2
Find the measure of triangle's third side in both .
Find area of all figures then add .
Answer:
42.5 unit²
Step-by-step explanation:
[tex]A_{1}[/tex] = 9 × 3.5 = 31.5
[tex]A_{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = 2
[tex]A_{3}[/tex] = 2² = 4
[tex]A_{4}[/tex] = [tex]\frac{2*5}{2}[/tex] = 5
[tex]A_{1}[/tex] + [tex]A_{2}[/tex] + [tex]A_{3}[/tex] + [tex]A_{4}[/tex] = 42.5 unit²

Answer: m1 m2 and m5 all equal to 135 as well
While m3 m6 and m4 are 45
Why: since they are on a line the two angles together should equal 180. So 180- 135= 45

Which is the graph of the equation ?
a
b
c
d
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
-1-(-5)/3-(-3)
4/6
2/3
y=2/3x-3

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)?
Answer:
326.56KStep-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
