Knowing that an exterior angle of a triangle is equal to the two interior angles that are away from the angle it is touching,
we get our equation:
6x+8=30+4x+2
Simplifying,
2x=24
x=12
So, we get the variable x is 12.
It's not over yet, since we were asked to calculate
6x+8
Substituting, we get

200 random people were surveyed at an amusement park and asked if they ride roller
coasters and if they play games while at the park. 130 of those surveyed ride roller
coasters. 86 of those surveyed play games. 70 of those surveyed ride roller coasters and
play games. Use the formulas in the text to answer the following questions.
a) What is the probability a person at the amusement park rides roller coasters or plays
games?
b) What is the probability a person at the amusement park does ride roller coasters?
c) Are the events of a person riding roller coasters and playing games mutually exclusive?
Answers
Answer:
let the P(ride roller coaster) be A and P(play games) be B
a. P(AUB) = P(A) + P(B) - P(AnB)
= 130/200 + 86/200 - 70/20.
= 146/200
= 73/100
b. P(A) = 130/200
= 13/20

[tex]14- 2.5f = 50\\\\14-50=2.5f\\\\-36=2.5f\\\\f=\frac{-36}{2.5}\\\\f=-14.4[/tex]
Hi!
14-2.5f=50
Move 14 to the right, using the opposite operation:
-2.5f=50-14
-2.5f=36

Explain why a change from 20 to 40 is a 100% increase, but a change from 40 to 20 is a 50% decrease. I don't under stand it
Answers
Answer:
Step-by-step explanation:
40 to 20 is a 50% decrease because you are halving it
20 to 40 is a 100% increase because you are adding 100% of 20 to 20 and you get 40.
Answer:
I hope this helps :)
Step-by-step explanation:
For 20 to 40, how much are you adding to your first number (20) to get your second number (40)?
You are adding 20 to your original number, which is the same amountSince you add the same amount to your original number (100% of your original number,) it is a 100% increase.For example: a 50% increase from 20 would be adding 50% of your original number (20) to the original number (e.g. 20 + (20/2) = 30 --> 50% increase)For 40 to 20, how much are you decreasing from your first number (40) to get your second number (20)?
You are subtracting 20 from your original number, which is half of the amountSince you subtract half (50%) of your original number, it is a 50% decreaseFor example: a 50% decrease from 30 would be taking away 50% of your original number (30) (e.g. 30 - (30/2) = 15 --> 50% decrease)[tex] \: [/tex]

Which of the following represents a function
Answers

All of the examples define relations between a domain and range.
Such a relation will be a function if and only if each value in the domain corresponds to at most one value in the range.
In the first example, the value
−
1
in the domain is associated with two values in the range, namely
−
5
and
1
.
In the second example, the value
−
1
in the domain is associated with two values in the range, namely
7
and
1
.
In the third example, the value
3
in the domain is associated with two values in the range, namely
2
and

In the fourth example, each of the values in the domain is associated with one value in the range, so this describes a function. Note however that the values
−

are both mapped to

The fraction of the project that the student can complete per hour is 8/15
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
For this case the problem is asking about the amount of project that can be completed per hour.
The independent quantity is the time spent by student on the project.
The dependent quantity here is the amount of the project completed by the student in the time spent.
Thus, we get the unit rate of amount of project completed per unit amount of time (unit time is one hour here) as:
[tex]R = \dfrac{\text{Amount of project completed}}{\text{Time taken}} = \dfrac{2/5}{3/4} = \dfrac{2}{5} \times \dfrac{4}{3} = \dfrac{8}{15} \: \rm project / hour[/tex]
We used the fact that:
[tex]\dfrac{a}{b} = a \times \dfrac{1}{b}\\\\and\\\dfrac{1}{a/b} = \dfrac{b}{a}[/tex]
Thus, that student can complete the considered project's 8/15 part per hour.

What single amount on April 1, 2012, is equivalent to a series of equal, semiannual cash flows of $5200 that starts with a cash flow on January 1, 2010, and ends with a cash flow on January 1, 2019? The interest rate is 6% and compounding is quarterly?
Answers
The single amount on April 1, 2012 that is equivalent to a series of equal, semiannual cash flows of $5200 is; $57,023.2
Compound Interest FactorWe are given;
Semi annual cash Flow; A_sa = $5200
Interest rate; r = 6%
From April 1, 2012 to January 1 2019 is 6.75 years
Thus; Period; T = 6.75 years
Cash flows is semi annual. Thus; t_a = 1/2
Thus; n_sa = 6.75 * 2
n_sa = 13.5
i_sa = 6% * 1/4 = 1.5%
Thus;
Single amount = 5200 * (P/A, 1.5%, 13.5)
From compound interest tables, P/A at n = 13.5 and at i = 3% by interpolation gives 10.966. Thus;
Single amount = 5200 * 12.137
Single amount = $63,112.4

find y=mx+b for line parallel to AB.
The line that is parallel will have the same slope as line AB:
the slope of line AB is
m=(8-3)/(-10-2)
=5/-12
=-5/12
Since the line going through X is parallel the vertical distance of the new line to AB is the same for all values of the domain(x-axis).
at x=-5 the point X has the y value of 10 which is 4 more than the y value for AB based on the graph.
To find the intercept b of the line going through X that is parallel to AB we just add 4 to the intercept of AB, which is 4 so

A van is delivering sacks of potatoes to two different shops in the ratio of 3:7.

How many bags of potatoes are on the van at the start.

How many bags of potatoes are on the van at the start.
The total number of bags the van have at the starting is 70.
What is ratio?Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.
According to the given question.
The sacks of potatoes delivered in two different shops are in the ratio 3:7.
Also, one shop has 28 more bags than the other.
Let the number of bags of potatoes at one shop be x.
Then, the bags of potatoes in another shop = x + 28
Therefore,
[tex]\frac{x}{28 + x } =\frac{3}{7}[/tex]
⇒ [tex]7x = 3(28 + x)[/tex]
⇒ [tex]7x = 84 + 3x[/tex]
⇒ [tex]4x = 84[/tex]
⇒[tex]x = 21[/tex]
So, the total number of bags
[tex]=x + (x + 28)[/tex]
[tex]=2x + 28[/tex]
[tex]= 2(21) + 28[/tex]
[tex]= 42 + 28[/tex]
[tex]= 70[/tex]
Hence, the total number of bags the van have at the starting is 70.

product of nine and a number means 9x.
three times the number means 3x.
The difference between the product of nine and a number and three times the number means that 9x - 3x.
9x - 3x = 6x
2) Let the number be x.
