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]

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°

(ANSWER ASAP) Solve the inequality. ​

Answers

Answer:

y > -6

Step-by-step explanation:

A farmer has a square field that is 1 mile wide by 1 mile long. Her irrigation system can water the northern 0.5 miles of her field. If her tomatoes are planted in a strip 0.3 miles wide, what is the area of her watered tomatoes?

Answers

Answer:

0.15mile^2

Step-by-step explanation:

Step one:

Given

lenght of field L= 1mile

width of field W= 1 mile

Required

The area that can be watered

we are told that the system can water 0.5miles North

This represents the length that can be watered

and the width of the tomatoes area is 0.3miles

Therefore the area that can be watered is

A= 0.5*0.3

A=0.15mile^2

Which is the graph of the equation ?

a


b


c


d

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

-1-(-5)/3-(-3)

4/6

2/3

y=2/3x-3
