In the figure d, e, and f are parallel lines. What is the value of x?

Answers

Answer:

x = 150

Step-by-step explanation:

Corresponding angles

180 - 60 = x-30

120 = x-30

150 = x

X=150

Explanation:
You take 180 as a straight line is 180° and you make the equation 180-60=x-30 Then you subtract 180 and 60 which equals 120 then add 30 to both sides and the equation after that should look like 150=X and thats your answer.

180-60=x-30
120=x-30
+30. +30
150=X

Describe, in great detail, how you would put a line into slope-intercept form (y = mx + b) if it wasn't already, so that it would be ready to graph.

Use 2y - 4x = 104 as your example.

Answers

Answer:

y=2x+52

Step-by-step explanation:

you would put y to one side so subtract 4x from the side with y and move it to 104

2y=104+4x

Now divide by 2 so you have y alone

y=52+2x

answer y=2x+52

2 is m, and 52 is b

What is the value of x and y?

Answers

Answer:

x = 5/4

y = 15/16

Step-by-step explanation:

y = 3/4x

5/2 x + 2y = 5

Substitute the first equation into the second equation

5/2x + 2(3/4x) = 5

5/2x + 3/2x = 5

Combine like terms

8/2x = 5

4x = 5

Divide by 4

4x/4 = 5/4

x = 5/4

Now find y

y = 3/4 x = 3/4 ( 5/4) = 15/16

X=5/4
Y=15/16

Answers

Answer:

the value of x n lengh of pq is 12.6

Answer:

12.6

Step-by-step explanation:

They are similar, so their lengths are the same. Except that The second one is bigger, therefore, you need to find the scale in which it is bigger.

7.2 ÷ 4 = 1.8   (line RS ÷ line LM because they are the correlating sides)

3.6 ÷ 2 = 1.8   (line RQ ÷ line LK because they are the correlating sides)

5.4 ÷ 3 = 1.8   (line SP ÷ line MJ because they are the correlating sides)

This tells us the scale is 1.8. So you just multiply 7 by 1.8 to get 12.6

This can be represented as: y = 1.8

7y = x

7(1.8) = x

12.6 = x

The surface area of the sphere is 192 cm^2
so the radius is ______ cm
and the volume would be _____ cm^3

Answers

Answer:

radius = 3.91 cm; volume = 250.4 cm^3

Step-by-step explanation:

Surface area formula = 4πr^2
Since you have everything except the radius, r, divide the surface area, 192 cm^2, to get the radius.
After you’ve done that, take the radius, 3.91, substitute it into the formula for volume.
Formula for volume is = 4/3πr^3

you and 5 of you friends go out to dinner. the total bill is $89. the group also wants to leave a 15% tip. if the total bill and tip are split evenly, approximately, how much will each person pay?

Answers

About $17.05,
Since 89/100= 1% of the total bill= 0.89
0.89*15= the total tip= 13.35
Add the total bill and the tip together would be $102.35,
And then you divide that between the 5 of your friends and you, so
102.35/6 which would equal to $17.0583 (3 repeating) for each person.
Each person would pay $20.47. 15% tip= $13.35 + $89= $102.35/5= 20.47
