Answer:
2) 44°Step-by-step explanation:
CA and CB are perpendicular to OA and OB, so the angles A and B are right angles.
Angles AOB and ACB sum to 180°
3x + 10 + 38 = 1803x = 180 - 483x = 132x = 132/3x = 44Correct option is 2) 44°

Given: B is the midpoint of AC
C is the midpoint of BD
Prove: AD=3AB
This one hurts to look at
Answers
Answer:
The proof is shown below.
Step-by-step explanation:
Given: B is mid point of AC and C is mid-point of BD.
To prove: AD=3AB
It is given that B is mid-point of AC.
⇒ AB = BC ...(1)
Also, C is mid-point of BD.
⇒ BC = CD ...(2)
From (1) and (2),
AB = BC = CD
Now, AD = AB + BC + CD
⇒ AD = AB + AB + AB (∵ AB = BC = CD )
Hence proved.

Answer:
s=2
Step-by-step explanation:
Simplify both sides of the equation.
8s−10=3(6−2s)
8s+−10=(3)(6)+(3)(−2s)(Distribute)
8s+−10=18+−6s
8s−10=−6s+18
Add 6s to both sides.
8s−10+6s=−6s+18+6s
14s−10=18
Add 10 to both sides.
14s−10+10=18+10
14s=28
Divide both sides by 14.
14s/14=28/14
s=2

[tex]-\frac43[/tex]
Step-by-step explanation:
Hello!
Slope is calculated by the formula [tex]\frac{Rise}{Run}[/tex].
Rise is the change in y between two pointsRun is the change in x between two points.The two points I'm picking is (0,0) and (3,-4).
The change in y (0 and -4) is -4.The change in x (0 and 3) is 3.Therefore, the slope is [tex]-\frac43[/tex].

2 lines are parallel unless both lines have the same slope and different y-intercept
If our line is y = 1/2x - 8
Then the other line should have (1/2)x as their slopes thus the first choice meet the requirement since it has same slope and different y-intercept.

1) No
2) Yes
3)No
4)Yes
Step-by-step explanation:
1) 3(8) is simplified to 24
But 24 < 24 is not a true statement because they are both equal.
2) 3(5) is simplified to 15
15 < 40 is a true statement because 15 is less than 24
3) 3(11) simplifies to 33
33 < 24 is not a true statement because 33 is more than 24
4) 3(6) simplifies to 18
18 < 24 is a true statement because 18 is less than 24

The constant of proportionality for the sales is 1/5. Therefore, option D is the correct answer.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
The given table shows the amount of money raised and the number of tickets sold by each of four students.
The constant of proportionality for the sales is

Judy is selling small candles at the fair for $4 each and large candles for $6 each. She collected $144 selling a
total of 28 candles. How many of each candle did she sell? Use x for the small candles and y for the large
candles.
Answers
HOW TO SOLVE
Let x = the number of small candles sold
Let y = the number of large candles sold
You are given two pieces of information:
(1) Number of candles sold: x + y = 28
(2) Revenue based on cost per candles sold: 4x + 6y = 144
Two equations, two unknowns - Solving by substitution (x = 28 - y)
4 * (28-y) + 6y = 144
112 - 4y + 6y = 144
112 + 2y = 144
2y = 32
y = 16
If y = 16, back substitute to find x = 12
Double check using revenue generated:
4x + 6y = 144
4(12) + 6(16) =? 144
48 + 96 = 144
