Step-by-step explanation:

Angle GHI + Angle IHK = 180 (Angles on the same straight line)

(x + 30) + (x+10) = 180

x+x+30+10 = 180

2x + 40 = 180

Answer:2x+40=180

Step-by-step explanation:

You want to equate everything for 180 since it's on a straight line

Therefore

(x+30)+(x+10)=180

x+x+10+30=180

2x+40=180

The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?

Answers

Answer:

x = 7

Step-by-step explanation:

The 2 angles are adjacent and sum to 180° , that is

11x + 8 + 12x + 11 = 180

23x + 19 = 180 ( subtract 19 from both sides )

23x = 161 ( divide both sides by 23 )

x = 7

What is the simplified slope for (3,2) and (5,12)

Answers

To find Y intercept
You do y2-y1/ x2-x1
Your y2 is 12, y1 is 2
Your x2 is 2 , x1 is 3
So 12-3/2-3
12-3 is 9
2-3=-1
9/-1 is -9
So your slope is -9

Answer:

-5

Step-by-step explanation:

Recall that slope = rise/run.

Here the change in y (the rise) is -10 (y changes from +12 to +2), and the  change in x (the run) is 2, since x increases from 3 to 5).

The slope of the line through these points is m = rise / run = -10/2 = -5

Find the missing side. Round to the nearest tenth when necessary.

Answers

Answer:

15.6

Step-by-step explanation:

Because it is a right triangle, you can use the Pythagorean Theorem. The theorem is c^2 = a^2 + b^2, with c being the hypotenuse, and a and b being the legs. So plug in the values and you will get 18^2=9^2 + b^2. Solve for b and you will get 15.6.

Answer:

x=15.59

Step-by-step explanation:

using the pythagorean theorem we know a²+b²=c²

also that c²-a²=b². in this case we're using the second one. c² is 18², and a² is 9². 18²-9² is 243. we then find the square root of that number to get x (b²). x=15.59 rounded to the nearest hundreth.

Answers

Answer: 1300 cm^3, 850 cm^2

Step-by-step explanation:

With a triangular prism, you need to calculate the surface area of the triangle first and then the length. Here's how to solve for the volume (A):

Triangles is b*h/2, plug in the equation

10*13/2

130/2

65

Now use the length of the rest of the shape, which is 20 cm.

65*20=1300

the volume is 1300 cm^3.

for B, finding the surface area requires you to analyze each individual part of the shape.

Each part colored in represents a different shape:

Red:

10*20=200

Blue:

13*10/2=65

65*2=130 (Two triangles)

Green:

13*20=260

260*2=520 (Two rectangles)

Add them all up together.

200+130+520= 850 cm^2

The net of a square pyramid is shown below. What are the possible areas for a single face in this net? Check all that apply.

A net with a square base with sides lengths of 5 meters, and 4 triangles with heights of 6 meters.
11 square meters
15 square meters
24 square meters
25 square meters
30 square meters

Answers

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.

Does one equal to zero?

Answers

Answer: 1 = 0

Step-by-step explanation:

The following is a “proof” that one equals zero.

Consider two non-zero numbers x and y such that

x = y.

Then x2 = xy.

Subtract the same thing from both sides:

x2 – y2 = xy – y2.

Dividing by (x-y), obtain

x + y = y.

Since x = y, we see that

2 y = y.

Thus 2 = 1, since we started with y nonzero.

Subtracting 1 from both sides,

Answer:

Yes, one does equal to zero

Step-by-step explanation:

Consider two non-zero numbers x and y such that

x = y. 

Then x2 = xy. 

Subtract the same thing from both sides: 

x^2 – y^2= xy – y^2.

Dividing by (x-y), obtain 

x + y = y. 

Since x = y, we see that 

2 y = y. 

Thus 2 = 1, since we started with y nonzero. 

Subtracting 1 from both sides, 

1 = 0.
