What is the relationship between corresponding angles if parallel lines are cut by a transversal 
_ Linear pair
_Congruent
_Supplementary
_Complemantary
Answer:
(b) _Congruent
Step-by-step explanation:
You want to know the relationship between corresponding angles where a transversal crosses parallel lines.
Corresponding anglesThe Corresponding Angles theorem tells you that corresponding angles at a transversal are congruent if and only if the lines are parallel.
Corresponding angles are congruent.
__
Additional comment
This fact is the basis for the simplest method of constructing a line parallel to a given line through an external point. (A transversal is drawn, and the angle is copied, making congruent corresponding angles.)
All of the other angle relationships at a transversal can be derived from this one using the usual relationships of linear pairs and vertical angles.

Answer:
15 years old45 liters of sugar solutionStep-by-step explanation:
You have ages in the ratio 3:5:7, with the average age being 25, and you want to know the age of the youngest. You have 45 L of a solution in the ratio sugar : salt = 1 : 2, and you want to know how much sugar solution to add to make the ratio 2 : 1.
AgesThe age ratios are an arithmetic progression with an odd number of terms, so the middle one is the average. That is, the average age of 25 years corresponds to 5 ratio units. Then the youngest boy is ...
3/5 × 25 = 15 . . . . years old
SolutionThe ratio 1 : 2 of sugar solution to salt solution tells you that the fraction that is sugar is 1/(1+2) = 1/3 of the whole amount, or ...
sugar solution = 1/3 · 45 L = 15 L
Then the salt solution is ...
salt solution = 45 L -15 L = 30 L . . . . . . . or (2/3·45 L)
To make the solution have twice as much sugar solution as salt solution, we need a total of 2·(30 L) = 60 L of sugar solution. We already have 15 L, so we need to add ...
added sugar solution = 60 L -15 L = 45 L
45 L of sugar solution must be added to make the sugar : salt ratio be 2 : 1.
__
Additional comment
The "solution" problem can also be worked by considering "ratio units." The original sugar:salt ratio is 1:2. To make it be 2:1 while keeping the salt constant, we need to increase the ratio from 1:2 to 4:2. That is, we need to add 4-1 = 3 units of sugar solution. The 45 L amount is the amount of 1+2=3 units of solution, so we need to add 45 L of sugar solution.

The SC Electric Company has bid on two electrical wiring jobs. The owner of the company believes that: the probability of being awarded the first job (event A) is 0.17; the probability of being awarded the second job (event B) is 0.5; the probability of being awarded both jobs (A and B) is 0.375. If the owner's beliefs are correct, which of the following statements must be true concerning event A and event B?
Statements must be true concerning event A and event B are that event A and B are independent and not mutually exclusive.
Define mutually exclusive event.Events that do not take place at the same time are said to be mutually exclusive. For instance, if a coin is tossed, the outcome will either be head or tail; we cannot obtain both outcomes. Since they do not occur at the same time, such occurrences are also known as disjunct events. Two events are mutually exclusive or disjoint in logic and probability theory if they cannot both occur at the same time. The results of a single coin flip, which can result in either heads or tails but not both, serve as an obvious illustration.

a) It is known that in a sports club, there are 1000 registered members.
60% of members play Tennis, 50% of members play Cricket,
70% of members play Football, 20% of members play Tennis and Cricket,
40% of members play Cricket and Football and 30% of members play Football and Tennis.
If someone claimed that 20% of members play all the three sports,
what is your opinion and why?
[Use inclusion and exclusion principle to provide your opinion]
Answer:
Using the inclusion and exclusion principle, we can calculate the percentage of members who play all three sports as follows:
60% of members play Tennis, 50% of members play Cricket, and 70% of members play Football.
Therefore, 60% + 50% + 70% = 180% of members play at least one of the sports.
However, this count includes members who play more than one sport, so we need to subtract out the members who play two sports and add back in the members who play all three sports.
20% of members play Tennis and Cricket, 40% of members play Cricket and Football, and 30% of members play Football and Tennis.
Therefore, 20% + 40% + 30% = 90% of members play at least two sports.
Subtracting this number from the total number of members who play at least one sport gives us 180% - 90% = 90% of members who play at least one sport but not all three sports.
To find the number of members who play all three sports, we need to subtract this number from the total number of members who play at least one sport:
180% - 90% = 90% of members who play at least one sport but not all three sports
180% - 90% = 90% of members who play all three sports
Therefore, according to the inclusion and exclusion principle, 90% of members play all three sports.
If someone claimed that 20% of members play all three sports, this would be incorrect based on the calculations using the inclusion and exclusion principle. The correct number of members who play all three sports is 90%, not 20%. This can be verified by using the given information about the percentage of members who play each individual sport and the percentage of members who play two sports in combination.
To clarify, the inclusion and exclusion principle states that to find the number of elements in a union of sets (in this case, the number of members who play at least one sport), we can add the number of elements in each set (the percentage of members who play each individual sport) and then subtract the number of elements that are counted multiple times (the percentage of members who play two sports in combination). We then add back in the elements that were subtracted out in the previous step (the percentage of members who play all three sports).
Using this principle, we were able to calculate that 90% of members play all three sports, rather than the 20% claimed by someone.

Answer:
We can conclude that there are 300 members who play tennis only. (total of 600 but 200 for members who play all 3 and 100 for players who play tennis and football)Only X = X - ( (X∩Y - X∩Y∩Z) + X∩Y∩Z + (Z∩X - X∩Y∩Z) )
Only X = 600 - ( (200-200) + 200 + ( 300-200) )
Only X = 600 - (0 + 200 + 100)
Only X = 600 - (300)
Only X = 300
There are 100 members who play cricket only. (total of 500 but 200 for members who play all 3 games and 200 for players who play cricket and football)Only Y = Y - ( (Y∩Z - X∩Y∩Z) + X∩Y∩Z + (X∩Y - X∩Y∩Z) )
Only Y = 500 - ( (400-200) + 200 + ( 200-200) )
Only Y = 500 - (200 + 200 + 0)
Only Y = 500 - (400)
Only Y = 100
There are 200 members who play football only. (total of 700 but 100 for tennis and football players, 200 for 3 games players, and 200 for cricket and football players.Only Z = Y - ( (Y∩Z - X∩Y∩Z) + X∩Y∩Z + (Z∩X - X∩Y∩Z) )
Only Z = 500 - ( (400-200) + 200 + ( 300-200) )

What is the solution to f(x) = -4 when f(x) = 3x + 5 ?
Answer: x=-3
Step-by-step explanation:
-4=3x+5
isolate x by moving all other variables to the right
-4-5=3x+5-5
-9=3x
x=-3
Answer:
-7
Step-by-step explanation:
To find the solution you'd have to plug in the -4 for every x you see but in this solution there is only one x so then you'd plug it in for that x. So then you'd have f(-4= 3(-4) + 5 and then you'd solve it. To solve it you would first multiply the 3 with the -4 because when something is in a parenthesis and there is a number beside with no sign that means you multiply. When you multiply you should get -12. After you get -12 you add 5 and your answer is -7.
When they give you an equation with an f(x) they sometimes give you inputs which you plug in to get your output. -4 was an input and -7 (your answer) is an output.

How to calculate Compound Interest?The interest charged on a loan or deposit is known as compound interest. It is the idea that we employ the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The major distinction between compound and simple interest is this.
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
Annual amount, A=P(1+[tex]\frac{r}{n}[/tex])∧nt
Calculation:Given,
P=1000$
A=1500$
r=13%=0.13
A=P(1+[tex]\frac{r}{n}[/tex])∧nt

Applying the net operating income ratio, the rent per unit needs to be $8,354.22 to generate an NOI of $100,000.
What is the NOI?The net operating income (NOI) is the result of the subtraction of the operating expenses from the gross operating income.
The net operating income ratio can be computed by subtracting the given operating expenses ratio from the operating gross income, which represents 100%.
Total
Rent per unit (per month) = $696.19 ($8,354.22/12) $150,376
Vacancy Rate (5% of Potential Gross Income) 7,519
Effective Gross Income $142,857
Operating Expenses (30% of Effective Gross Income) 42,857
Net Operating Income (NOI) $100,000
Number of Units 18
Working Backwards:Gross operating income = net operating income + operating expenses
Operating expenses = 30% of effective gross income
Net operating income = 70% of effective gross income (100 - 30%)
= $100,000
Effective Gross Income (100%) = $142,857 ($100,000 ÷ 70%)
Vacancy rate = 5% of potential gross income
Effective Gross Income = 95% (100 - 5)
Potential gross income = $150,376 ($142,857 ÷ 95%)
Number of units = 18
Rent per unit = $8,354.22 ($150,376/18)
Rent per month = $696.19 ($8,354.22 ÷ 12)
Thus, a rent of $8,354.22 per unit can generate a Net operating income of $100,000.

1. A sports team has 65 men and 35 women as members. A new activity has just begun and some new members have joined. Given that the number of men is now 60% of the total members, how many of the 50 new members were women?
2. A rectangle is 50cm long and 40cm wide. Its length is extended by 12% and its width is reduced by 15%. Does the perimeter of the rectangle change? Does the area of the rectangle change? Justify your answer.
Answer:
1) 25 women joined;2) Perimeter stayed same but area became smaller.-----------------------
Question 1Initial number of sports team:
65 + 35 = 100Number after new members joined:
100 + 50 = 15060% of 150 members are men, number of men is:
150*60/100 = 90Number of women:
150 - 90 = 60Number of newly joined women:
60 - 35 = 25Question 2Perimeter of the rectangle:
2(50 + 40) = 2(90) = 180 cmArea of rectangle:
50*40 = 2000 cm²New dimensions:
50 + 12% = 50*1.12 = 56 cm,40 - 15% = 40*0.85 = 34 cm.New perimeter:

A certain volcano has an elevation of 13,410 feet. A nearby oceanic trench has an elevation of 21,795 feet below sea
level. Find the difference in elevation between those two points.
For the piecewise function below, which of the following statements are true?
Please help will give brainlist if correct!
The correct option is (b) i.e. f(0) > f(2).
What is Domain?
The entire range of independent variable values is the domain of a function. In straightforward terms, this definition means The collection of all x-values that can cause the function to "work" and produce actual y-values is known as the domain.
We have,
f(x) = (x+2)^2 - 1 , -4 ≤ x ≤ 0
-x + 1 , 0 ≤ x ≤ 2
5/2 log ( -x +5) - 1 , 2 < x < 5
Now, f(0) = (x+2)^2 - 1
= (0+2)^2 - 1
= 4 - 1 = 3
Similarly, f(2) = - x +1
= - 2 + 1
= - 1.
Hence, f(0) > f(2) because 3 > -1.
∴ The correct option is (b).

A line goes through (minus 3, 0) and (0, 3). Another line goes through (minus 1, minus 3) and (1, 3). Both the lines intersect at (1.5, 4.5).
In the given equation, Y = 3x is at (0, 3) and a line passes through (-3, 0).
What do you mean by Equation?A mathematical statement known as equation is given by joining two expressions with the equal sign. For instance, 3x - 5 = 16 is an equation. This equation can be solved, and the result shows that the value of the variable x is 7.
A mathematical equation links the two phrases on either side of the sign. It typically only contains an equal sign and one variable. similar to 2x - 4 = 2.
Either identities or conditional equations can be used to classify equations. Each value of the variables corresponds to a specific identity. A conditional equation can only be true for a certain range of variable values. An equation is represented by two expressions being separated by the equals sign ("=").
A line goes through (- 3, 0) and (0, 3)
The equation is
y - y1 = y2 - y1/ x2- x1
