Answer:
Inductive
Step-by-step explanation:
The given argument presented is an example of inductive reasoning.
What is inductive reasoning?Inductive reasoning entails drawing broad generalizations based on a small number of observations, and the conclusion is not necessarily guaranteed to be correct, but simply likely based on the data.
The argument presented is an example of inductive reasoning, because it is based on a specific observation and a generalization that goes beyond the available evidence.
While the previous and current mayors may be honest, based on this limited evidence, it is not necessarily true that all mayors are honest.
The argument makes the assumption that the honesty of these two persons is indicative of all mayors, which is a conclusion based on little evidence.

Andrew can paint the neighbor's house 5 times as fast as Bailey. The year Andrew and Bailey worked together, it took them 2 days. How long would it take each to paint the house?
Answer:
12 days for Bailey
2.4 days for Andrew
Step-by-step explanation:
If Andrew is 5 times as fast, then Andrew + Bailey are 6 times as fast as Bailey alone.
That means Bailey would take 2*6 = 12 days to paint alone.
Since Andrew is 5 times faster, he'd only take 12/5 = 2.4 days.

$6.25. Simone wants to buy 15 tickets. At
these rates, how much more will she spend
if she only buys packs of 3 tickets?
She will spend 5 dollars extra if she only buys packs of 3 tickets.
What is a numerical expression?A numerical expression is written in form of numbers and their operations.
According to the given question we can buy 15 tickets in two ways either buying 5 packs which contain 3 tickets and cost 6.25 dollars each pack or we can buy 3 packs which contain 5 tickets which costs 8.75 dollars.
For the first case if we buy 5 packs of tickets that contain 3 tickets it will cost (5×6.25) dollars = 31.25 dollars.
In the second case buying 3 packs of tickets that contain 5 tickets that will cost us (3×8.75) = 26.25 dollars.
∴ She will spend (31.25 - 26.25) = 5 dollars she will spend extra if she only buys packs of 3 tickets.

11. Descartes
has $9. He works 5 hours
and earns $8 each hour. Write an
expression
to represent the situation
Answer: y = 8x + 9
Step-by-step explanation: Descartes begins with only $9.00, so 9 is the y-intercept. He makes $8.00 every hour, so that is the slope.
y = mx + b
m is the slope, and b is the y-intercept.
y=8x + 9
The expression that represents the given situation is y = $49.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it isgiven that,
Descartes has Money = $9
Each hour earning = $8
Total time of work = 5 hours
So, total money earned in 5 hours = 8*5 = $40
Let y be the total money Descartes has.
So total money Descartes has = Money + total money earned in 5 hours
⇒ y = $9 + $40
⇒ y = $49
This is the required expression for the present situation.
Thus, The expression that represents the given situation is y = $49.

∠1 and ∠2 form a linear pair. If m ∠1 is eight more than m ∠2 find the measures of both angles
A linear pair is formed of ∠1 and ∠2. The measures of the angle ∠1 is 20 and ∠2 is 160.
Given that,
A linear pair is formed of ∠1 and ∠2.
We have to find the measurements of both angles if m∠1 is eight more than m∠2.
When they refer to something as "linear," they mean that two angles create a straight line (or, 180 degrees). In other words, the two angles add up to 180.
Let us take the ∠1 as x
Then ∠2 will be 8x.
Now, we can write as
x+8x=180
9x=180
x=180/9
x=20
Therefore, the measures of the angle ∠1 is 20 and ∠2 is 8×20=160.

Answer: 4.5
Step-by-step explanation:
To break even, we need the total profit to be equal to 0. If we make x dollars in 2012, then we need to solve
2.5 + 1.75 + (-3.3) + (-1.4) + x = 0
This gives us x = 0.45 in thousands.
Since the question asks us to give the answer in hundreds, we multiply by 10 and get 4.5. Thus the profit in 2012 must be 4.5 (in hundreds) to break even.

You invested $27,000 in two accounts paying 4% and 7% annual interest, respectively. If the total interest earned for the year was $1440 how much was invested at each rate?
a = amount invested at 4%.
b = amount invested at 7%.
we know that whatever "a" and "b" may be, they total 27000, so we can say that a + b = 27000, likewise we can say that b = 27000 - a.
how much will it be for 4% of "a"? well, that's just (4/100) * a, or 0.04a.
how much will it be for 7% of "b"? well, that's just (7/100) * a, or 0.07b.
we also know that the earned interest by those two interest amounts is 1440, so
[tex]\begin{cases} a + b = 27000\\ b = 27000 - a \end{cases}\hspace{5em}0.04a~~ + ~~0.07b~~ = ~~1440 \\\\\\ \stackrel{\textit{substituting "b"}}{0.04a~~ + ~~0.07(27000-a)~~ = ~~1440}\implies 0.04a+1890-0.07a=1440 \\\\\\ 1890-0.03a=1440\implies -0.03a=-450\implies a=\cfrac{-450}{-0.03} \\\\\\ 15000=\textit{\LARGE a}\hspace{15em}\stackrel{27000~~ - ~~15000}{\textit{\LARGE b}=12000}[/tex]
Find the slope(m) and y-intercept (b) of each representation below.
m= 15
b= 45
y= 15x +45
Concept:Overall equation
The equation of a line in slope-intercept form is given by y= mx +b, where m is the slope and b is the y-intercept.
Slope, m
The slope is the measure of how steep the line is. It also defines how the y-axis changes with respect to the x-axis. The formula for finding slope is as shown below.
[tex]\boxed{\text{Slope}=\frac{y_1-y_2}{x_1-x_2} }[/tex]
where [tex](x_1,y_1)[/tex] is the first coordinate and [tex](x_2,y_2)[/tex] is the second coordinate
y-intercept, b
This is the y-value in which the line cuts through the y-axis (vertical axis).
Working:Slope, m
Let's identify two pairs of coordinates on the line.
2 square units on the y-axis represent $30. Thus, 1 unit on the y-axis represents $15.
The 2 points are: (0, 45) and (5, 120)
Substitute the 2 points into the slope formula:
Slope
= [tex]\frac{120-45}{5-0}[/tex]
= [tex]\frac{75}{5}[/tex]
= 15
Thus, m= 15.
y-intercept, b
From the graph, the line cuts through the y-axis at y= 45.
Thus, b= 45.
Overall equation
Substitute m= 15 & b= 45 into y= mx +b:
∴ The equation of the line is y= 15x +45.

Identify the segment bisector of
__
XY
The segment bisector of line segment XY is line n.
The length of the line segment XY is 6 units.
How do you define the line segment?A line segment is a section of a line with two endpoints. A line segment, unlike a line, has a fixed length.
A line segment's length can be measured in metric units including such millimeters and centimeters, or in customary units such as feet or inches.A bisector is a line that separates a straight line or perhaps an angle into two equal parts. A segment's bisector always contains the segment's midpoint.As per the given diagram in the question.
It is clear that the line segment XY is being divided by another line named n.
Thus,
The two segment of the line segment XY must be equal.
XM = MY
Substitute the values from the diagram;
5x + 8 = 9x + 12
Simplifying;
4x = -4
x = -1
Put the values in each segment;
XM = 5x + 8
XM = 5(-1) + 8
XM = 3 units.
Put the value in MY
MY = 9x + 12
MY = 9(-1) + 12
MY = 3 units.
As, it is clear from above values that the both segment are equal of 3 units each.
XY = XM + MY
XY = 3 + 3 = 6
Therefore, the value of XY is 6 units.

Explain your answer!
Do not spam answers!
Show your work!
Nonsense answers will be reported and delete your answers.
Thanks!
Answer:
5 hours and 48 minutes
Step-by-step explanation:
The equation for finding average speed is: [tex]\frac{\text{Total Distance}}{\text{Total Time}}[/tex]
Let x represent the distance for both the journey from Riley's college to home and back. We can use one variable to represent this because both distances are the same.
We also know that the total round trip took 12 hours. Let y represent the time it took for Riley to drive from college to home. Therefore the time it takes for Riley to drive from home to college is 12 - y.
Using this information, we can set up a system of equations.
Setting up a System of Equations[tex]65.1=\frac{x}{y}\\\\69.6=\frac{x}{12-y}[/tex]
Multiply both sides of the first equation by "y" and both sides of the second equation by "12 - y".
[tex]65.1y=x\\\\835.2-69.6y=x[/tex]
Since both 65.1y and 835.2-69.6y are equivalent to x, we can set them equal to each other.
[tex]65.1y=835.2-69.6y[/tex]
Now, we have to solve the equation for time or "y".
Solving for Time[tex]65.1y=835.2-69.6y[/tex]
Add 69.6y to both sides
[tex]65.1y+69.6y=835.2[/tex]
[tex]134.7y=835.2[/tex]
Divide both sides by 134.7
[tex]y\approx6.2 $ hours = Six hours Twelve Minutes[/tex]
This is the time it took for Riley to drive from college to home, therefore the time it took for Riley to drive from home back to college is:
[tex]12-6.2=5.8=5$ hours and 48 minutes[/tex]
5 hours and 48 minutes
