Answer:
x = 112
y = 76
Step-by-step explanation:
x + 68 = 180
x = 180 - 68
x = 112
y = 76 (Because of alternate interior angles)

Answer:
12 boys
Step-by-step explanation:
4/(4+6) × 30
= 4/10 × 30
= 12
I forgot how to get the mean, help is appreciated :) I've got the other ones though! ^^
To find the mean, add up all the numbers in the data set. After, divide by how many numbers are in the data set. Try it out with your data. If you need help with the actual answer, feel free to write in the comment box.

whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
Hey there!
7/4 = 35/m
CROSS MULTIPLY BOTH of your NUMBERS
7(m) = 4(35)
7(m) = 7m
4(35) = 140
NEW EQUATION: 7m = 140
DIVIDE 7 to BOTH SIDES
7m/7 = 140/7
CANCEL out: 7/7 because that gives you 1
KEEP: 140/7 because that gives you the value of m
140/7 = m
Solve above and you have the answer of m
140/7 = 20
Therefore, the value of m = 20
Answer: m = 20
Good luck on your assignment and enjoy your day!

What is the volume of each cup in terms of u?
A. 157 cm
B. 45 cm
C. 135 cm
• D. 180 cm
9514 1404 393
Answer:
B. 45π cm^3
Step-by-step explanation:
The volume is given by ...
V = 1/3πr^2h
where r is the radius (half the diameter) and h is the height. With the given numbers, we have ...
V = (1/3)π(3 cm)^2(15 cm)
V = 45π cm^3 . . . volume of each cup

y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.
Answer:
y= -1.328
Step-by-step explanation:
15= k*-18
15=k*-18 (divide both sides by -18)
It doesn't go in evenly so you are left with a negative decimal
k= -0.83
Now find y
y= -0.83(1.6)= -1.328

QPR = 35º
QRP = 60º
Step-by-step explanation:
2x + 1 = x + 18
Subtract x from both sides
x + 1 = 18
Subtract 1 from both sides
x = 17
QPR = 2x + 1
QPR = 2(17) + 1
QPR = 35º
-------------------------------
8y - 4 = 4y + 28
Subtract 4y from both sides
4y - 4 = 28
Add 4 to both sides
4y = 32
Divide both sides by 4
y = 8
QPR = 8y - 4
QRP = 8(8) - 4
QRP = 60º

40, degrees. Nuha needs to push it the rest of the way.
Answer:
The answer is A
Step-by-step explanation: BIG BRAIN
The equation that will tell us the measure of the additional angle, a, that Nuha needs to push the door before she can get out is D: 160 - 40 - a.
To determine the equation that will give us the measure of the additional angle, a, that Nuha needs to push the door before she can get out, we can break down the information provided:
1. The door needs to rotate 160° for Nuha to pass through.
2. The wind pushed the door 40°.
To find the additional angle that Nuha needs to push the door, we can subtract the angle already rotated (40°) and the angle she needs to pass through (160°) from the total rotation angle:
Total rotation angle = Angle already rotated + Angle Nuha needs to push + Additional angle Nuha needs to push
Based on this equation, we can eliminate options A, B, and C since they do not accurately represent the situation.
The correct equation is option D: 160 - 40 - a. This equation represents subtracting the angle already rotated (40°) and the angle Nuha needs to pass through (160°) from the total rotation angle, leaving the additional angle (a) that Nuha needs to push the door.

Nuha is going through a revolving door that needs to rotate 160° to allow her to pass through. The wind pushed the door around 40°. Nuha needs to push it the rest of the way.
Which equation will tell us the measure of the additional angle, a, that Nuha needs to push the door before she can get out?
Choose 1 answer:
A: 160+40= a
B: 40 x 2 = a
C: 160 ÷ 40 = a

whats is the answer for 4x - 10 < 18
Answer:
x<7
Step-by-step explanation:
Answer: x=7, x<18, true
Step-by-step explanation: -10 becomes +10, then you add 10+18. 4x<28 is now the expressio. 28/4=7, x=7 and x or 7<28. This equation is true.

Answer:
100
Step-by-step explanation:
because 4, 3, and 2 all make 180 and 4 and 2 are both 40 so you add that which makes 80 and then you take 180 and subtract 80 which gives you 100
Answer:
100
Step-by-step explanation:
This is because angle 1 and angle 2 are congruent, so both of them are 40 degrees. To find angle 3, you do 40+40 which is 80. You then subtract 180-80=100. This is because angles 1, 2, and 3 are all on 1 straight line.

11 . (2c + 3d)
Answer:
A, C, and E
Step-by-step explanation:
For the first one, distribute -11 to each value. A negative times a negative is a positive, so -11×-2c is 22c. -11×-3d is 33d. So the first one is right. For the third one, distribute 1/3 to each value. 1/3 of 66c is 22c, and 1/3 of 99d is 33d, so the third one is correct as well. For the last one, distribute 11 again. 11×2c is 22c and 11×3d is 33d, so the last one is correct.
