If a transversal crosses three non-parallel lines, how many pairs of vertical angles are formed? Explain your answer
Answer: Each transversal crossing a line generates 2 pairs of vertical angles and for 3 transversal crossing the same line it will be 3 x2 = 6 pairs (or 12 angles)
Step-by-step explanation:
Simple Answer: Six pairs of vertical angles are formed, two for each line crossed by the transversal.

A coffee shop needs to purchase custom cups. Company C charges a flat fee of $155 plus $15 perrl cup. Company D does not have a flat fee but charges $30 per cup.
What is the minimum number of cups that must be ordered for company C to be a better deal than company D?
Answer:
11 cups
Step-by-step explanation:
Not really a method just started at 10 and then realised deal d was better so go up by one so 11 and c worked out better as I timed 30 by 11 and 15 by 1 + the flat fee.
Giovanni justifies whether the expression –4x – 8 is equivalent to Negative 2 (x + 1) minus 2 (x + 3) by letting x = 3 in both expressions. What is the value of each expression when x = 3?
Answer:
They are equivalent
Step-by-step explanation:
-4(3)= -12 -8 = -20
-2 (3+1)= -6-2 = -8
-2(3+3)= -6-6 = -12 -8+-12=-20
both equal -20.
Answer:
-20 -20
Step-by-step explanation:
Item 1 A discounted concert ticket costs $14.50 less than the original price p . You pay $53 for a discounted ticket. Write an equation that can be used to find the original price. Equation: =53 Find the solution to your equation. The original price of the ticket was $.
Answer:
$53 + $14.50 = x
x = $67.50
Step-by-step explanation:
Let us assume the original price be x
It is given that
The discounted ticket is $53
And, the discounted concert ticket cost is $14.50 lower than the orginial price
So, the equation is
$53 + $14.50 = x
Now the x is
= $53 + $14.50
= $67.50
Hence, x denotes the original price of the ticket
We simply added the above two amounts
Antoine made $33,284 last year. He received a 4.5% annual raise. What will his new salary be for the coming year?
Answer:
$34,781.78
Step-by-step explanation:
the annual salary is $33,284 which is 100%and the raise is 4.5%which you add 100% .u add the 100% because it is a profit .then it becomes 104.5% .
the equation is: $33,284=100%
? =104.5%
Cross multiply then the equation is:
$33,284×104.5%/100%=34,781.78
You got to McDonald's and order some food for you and your friends.Your friends give you a list of what you need to order: 1 cheeseburger, 2 orders of fries, 3 cheeseburgers, and 3 orders of fries. How can you simplify this order so that way you don't have to read of the exact list they gave you.
Answer:
4 cheeseburgers and 5 fries.
Step-by-step explanation:
Here, the orders given are as follows:
1 cheeseburger,
2 orders of fries,
3 cheeseburgers, and
3 orders of fries
If we observe closely, it can be seen that there are orders of cheeseburgers 2 times and orders of fries also 2 times.
In order to simplify the given list, we must add the similar kind of orders together.
Therefore the given order list can be written as:
1 cheeseburger + 3 cheeseburgers, and
2 orders of fries + 3 orders of fries
OR
In other words:
4 cheeseburger, and 5 orders of fries
Therefore, the simplified order is:
4 cheeseburger, and 5 orders of fries
The nth term of an arithmetic sequence is given by an
an= 4 + 5(n-1). If you were to graph ordered pairs where x is the term number and y is the term, what linear equation would describe the line that passes through the points?
Answer:
y = 5x - 1Step-by-step explanation:
aₙ = y n = x
aₙ = 4 + 5(n-1)
y = 4 + 5(x - 1)
y = 4 + 5x - 5
y = 5x - 1

Ms. Jackson’s class is going to the zoo. The zoo charges $10 for an adult and $6 for each student. If the total was $118, how many students went to the zoo?
Answer:
so that means 10 parents went and 3 children went
Step-by-step explanation: first you count by 10,s to get to 100 like this 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 and then 10 parents went and then you would count by 6 to get to 18 like this 6, 12, 18.

Look at △STU on this coordinate grid. Suppose that △S'T'U' is the result of a dilation of △STU with a scale factor of 2. What are the coordinates of point S'? *
Answer:
(4,2)
Step-by-step explanation:
THIS IS ASSUMING you are scaling it around 0,0
S is 2,1.
(x',y') = (2,1)
You want to find the coords with a scale factor of 2.
(x',y') = 2(2,1)
x',y' = 4,2

Someone I need it asapppp
Answer: is II and III an option those are the ones that would be correct.
Step-by-step explanation:
You can only have one of each domain. For example you cannot have (0,0) and (0,1) since that won’t pass the vertical line test, you can have (0,0) and (4,0) as long as the domains are different, they can still have the same ranges.

What value of x is in the solution set of 3(x – 4) = 5x + 2?
A0 -10
B-5
C5
D10
Answer:
-5?
Step-by-step explanation:
3(x - 4) = 5x - 2
3x - 12 = 5x - 2
3x - 5x = -2 + 12
-2x = 10
x = -5

What is the solution to 10(2x - 4) = 100x? Please do your best.
10(2x-4)=100x
20x-40=100x
-40=100x-20x
-40= 80x
-40/80x= -0.5
10(2x-4)=100x
20x-40=100x
20x=100x+40
20x-100x=40
-80x=40

Find the range of allowable values based on the given information.
Round to the nearest tenth.
15; can vary by 2%
Answer:
14.7 to 15.3
Step-by-step explanation:
To find the range of values that can are permitted to vary by 2% of 15, first,
find the value of 2% of 15:
[tex] \frac{2}{100} * 15 = \frac{30}{100} = 0.3 [/tex]
The range of values allowed would either be 0.3 less than 15 or 0.3 more than 15.
Thus, the values would be:
15 ± 0.3
= 15 - 0.3 or 15 + 0.3
= 14.7 or 15.3
This means the minimum value allowed is 14.7, while the maximum value allowed is 15.3.
Therefore, the answer is:
14.7 to 15.3
Answer:
14.7 to 15.3
Step-by-step explanation:
Step-by-step explanation:

find the value of 2% of 15:
The range of values allowed would either be 0.3 less than 15 or 0.3 more than 15.
Thus, the values would be:
15 ± 0.3

This means the minimum value allowed is 14.7, while the maximum value allowed is 15.3.
Therefore, the answer is:
14.7 to 15.3

03.01 MC) A surveyor randomly interviewed 65,439 people who live in Virginia to gather information on whether national healthcare is accomplishing its goals. Part A: What are the population and sample in this survey? (4 points) Part B: The survey found that 71% of females and 88% of males visited a family doctor at least once in the past year. Do you think these approximations of the sample are close to approximations of the entire population? Explain. (6 points)
Answer:
Part A: The population and the sample of the survey are;
The population = The entire population of the country
The sample = 65,439 people in the state of Virginia
Part B: Given that the survey was based on only one state and only one model of health care delivery, the approximations of the sample will not be close to the approximations of the entire population
Step-by-step explanation:
The given information are;
The number of people interviewed in the survey = 65,439 people
The location of the people surveyed = Virginia
The goal of the survey = The effectiveness of the national healthcare
The number of females that visited a family doctor at least once in the past year = 71%
The number of males that visited a family doctor at least once in the past year = 88%
Part A: The population and the sample of the survey are;
The population = The entire population of the country
The sample = 65,439 people in the state of Virginia
Part B: Given that the survey was based on only one state and only one model of health care delivery, the approximations of the sample will not be close to the approximations of the entire population.
