What is the value of the missing angle in the triangle?
A) 156 Degrees
B) 66 Degrees
C) 142 Degrees
D) 150 Degrees
Answers
Answer:
A
Step-by-step explanation:
We know that the sum of the interior angles of a triangle must equal 180°. So:
[tex](12)+(12)+x=180[/tex]
Solve for x. Add on the left:
[tex]24+x=180[/tex]
Subtract 24 from both sides:
[tex]x=156\textdegree[/tex]
Our answer is A.
And we're done!
Answer:
A) 156 Degrees
Step-by-step explanation:
All angles in a triangle ALWAYS adds up to 180°.
Step 1: Set up equation
12° + 12° + x° = 180°
Step 2: Solve for x
Combine like terms: x° + 24° = 180°Subtract 24° on both sides: x° = 156°Step 3: Check
All angles should add up to 180°. Plug it in and check.
156° + 12° + 12° = 180°
156° + 24° = 180°
180° = 180°

2/5 t is the probability that the balloon will be either red or blue.
Thus option A is correct.
What is probability?The mathematical discipline known as probability specializes in determining the possibility of an event occurring. Probability, which expresses the probability of a risk, is calculated by dividing the total possible combinations by the frequency of favorable events. Composite reliabilities vary from 0 to 1, with 1 representing certainty and 0 representing hesitation.
The probability of the event will be taken as
The fact that the data of red and blue will have a chance of occurring in the event
The first draw chance would be 20/100 = 1/5
The second draw would be 20/100 = 1/5
P = 20 / 100 + 20 / 100
P = 1/5 + 1/5
P = 2/5
Therefore, option D is the correct option.

Lazarus’ Boat Rentals charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. Robert’s Boat Rentals does not charge a yearly fee but charges $14.75 every time a member rents a boat. How many times would a person have to rent a boat for Lazarus’ and Robert’s charges to be equal
Answers
Answer:
The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal = 20 times
Step-by-step explanation:
Answer: The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal is 20 times
Step-by-step explanation:
The given information are:
For the Lazarus' Boat Rentals company
The yearly charges by Lazarus' boat company = $105
The charge each time a member rents a boat = $9.50
For the Robert's Boat Rentals company
The yearly charges by Robert's boat company = $0
The charge each time a member rents a boat = $14.75
Let the number of times required before the charges for both Lazarus' Boat Rentals company and Robert's Boat Rentals company to be equal, we have:
$105 + $9.50 × t = $14.75 × t
∴ t = $105/($14.75 - $9.50) = 20 times
The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal = 20 times.

Answer:

5 7
1/2 -2
-1 -5
Step-by-step explanation:
You have to plug the numbers in to find out the chart
2(3)-3=y
6-3=y
3=y
2x-3=(7)
add the 3 on both sides to make the x by its self
2x=10
divide both sides by 2
x=5
2(1/2)-3=y
1-3=y
y=-2
2x-3=(-5)
add the 3 to both sides
2x=-2
divide the 2 on both sides
x=-1
We get 2(3)-3=y
6-3=y
So, y=3
next, substitute y=7 in the equation
We get 2x-3=7
2x=7+3
2x= 10
X= 5
Keep substituting the values..
When x= 1/2, Y = -2
When y= -5, x= -1
