Find the slope of the line that passes through each pair of points
Answer:
-3
Step-by-step explanation:
Start at the y-intercept which is 1, and go down however many times it would take, for you to go across and get to a point. Basically to find the slope is rise over run. In this case you would "rise" -3 and run 1. I haven't done this in awhile. If its wrong, I apologize. Have a good night.

The float committee made a scale model of their float before they started construction. The float committee used the scale 1 inch: 3 feet to create their model. The actual float will be 18 feet long. What is the length of the scale model float in inches? Enter your answer in the box.
Answer: The float committee made a scale model of their float before they started construction. The float committee used the scale 1 inch : 3 Feet to create their model. The actual float will be 18 feet long.
So this being said.
Step-by-step explanation:
Your answer should be 6 inches. I hope this helps!
The length of the scale model of the float is required.
The length of the scale model would be 6 inches.
Scale diagramsIt is given that one inch of the scale model of the float is three feet of the actual float.
[tex]1\ \text{inch}=3\ \text{feet}[/tex]
Now, what 1 feet of the float represents in the scale model is required.
So, we divide both sides by 3
[tex]1\ \text{feet}=\dfrac{1}{3}\ \text{inch}[/tex]
The length of the actual float is 18 feet.
[tex]18\ \text{feet}=18\times \dfrac{1}{3}=6\ \text{inches}[/tex]

A telephone poll asked people whether they like playing golf. Of the 100 people polled,20 like playing golf. What percentage of the people like playing golf?
Given:
Of the 100 people polled, 20 like playing golf.
To find:
The percentage of the people who like playing golf.
Solution:
In the poll,
Total number people = 100
Who like playing golf = 20
Now, percentage of the people who like playing golf is
[tex]Required \%=\dfrac{\text{Number of people who like playing golf}}{\text{Total number people in poll}}\times 100[/tex]
[tex]Required \%=\dfrac{20}{100}\times 100[/tex]
[tex]Required \%=20[/tex]
Therefore, 20% of the people like playing golf.

A cake recipe calls for 1.5 cups of milk and 3 cups of flour. Seth made a mistake and used 5 cups of flour. How many cups of milk should he use to keep the proportions correct
Answer:
2.5cup of milkStep-by-step explanation:
Step one:
we are told that the ratio of milk to flour is 1.5cups to 3 cups
in other words, to prepare cake we need 1.5 cup of milk and 3 cups of flour
if we use 5 cups of flour we can balance up using the relation below
1.5cups of milk require 3 cups of flour
x cups of milk require 5 cups of flour
cross multiply we have
x=1.5*5/3
x=7.5/3
x=2.5cup of milk

Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well?
Answer:
The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].
Step-by-step explanation:
The point-slope form of the equation of the line is represented by the following expression:
[tex]y - y_{o} = m\cdot (t-t_{o})[/tex] (1)
Where:
[tex]t[/tex] - Time, measured in seconds.
[tex]y[/tex] - Height below the top of the well, measured in feet.
[tex]t_{o}[/tex], [tex]y_{o}[/tex] - Known information of the well, measured in seconds and feet, respectively.
[tex]m[/tex] - Slope, measured in feet per second.
If we know that [tex](t_{o},y_{o}) = \left( 1\,s, -1\,ft\right)[/tex] and [tex]m = 4\,\frac{ft}{s}[/tex], then the equation in point-slope form of the line is:
[tex]y + 1 = 4\cdot (t-1)[/tex]
The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].
An employee’s hourly raise went up from $11 per hour to $16 per hour. What is the rate of increase? Round to the nearest percentage.
Answer:
45%Step-by-step explanation:
Step one:
given data
intial pay= $11 per hour
final pay= $16 per hour
Required
% increase
Step two:
%increase= final-initial/initial*100
substitute
%increase= 16-11/11*100
%increase=5/11*100
%increase= 0.45*100
%increase= 45%
Hence the percent raise is 45%

Kelly is using a compass and straightedge to perform the Geometric construction below.
Which of the following best describes the figure Kelly is constructing?
Answer:
The answer is A
Step-by-step explanation:
The line is perpendicular to RS through S
There are several constructions that can be done with the straightedge and the compass.
The statement that describes the figure Kelly is constructing is: (c) a line parallel to RS through Q
From the figure, we have the following observations
Two arcs intersect on line RSAnother set of two arcs intersect on the same level as point Q.When a line is drawn from point Q through the intersection of these lines, the line would be parallel to line RS.
Hence. we can conclude that:
Kelly is constructing (c) a line parallel to RS through Q

An angle measures 48° more than the measure of its complementary angle. What is the
measure of each angle?
Answer:
The angles measure 21 degrees and 69 degrees.
Step-by-step explanation:
Complementary angles have a sum of 90 degrees when added together.
Let's call the complementary angle x. We can write the angle that we're looking for as in terms of x as x + 48.
Since these angles must sum to 90 we can write the equation and solve:
x + x + 48 = 90
2x + 48 = 90
2x + 48 - 48 = 90 - 48
2x = 42
x = 21
x + 48 = 69
21 degrees and 69 degrees.
Answer:
69° and 21° is the answer.

Given the replacement set:
b={4.4, 5.4, 6.4}
Which inequality is true?
b−6>10.4
b+6<10.4
b−8≥12.4
b+8≥12.4
Answer:
b+8≥12.4
Step-by-step explanation:
Here, we want to select the correct option
From what we have here;
b ≥12.4-8
b ≥ 4.4
Looking at the range of values in the set
We can see that the smallest of values is 4.4
This tells exactly the correctness of the last option as the values of b are 4.4 or greater
