"Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answers
The slope of the line = rise of the line / run of the line = 2/2 = 1.
How to Find the Slope of a Line?The slope (m) of a line can be determined by finding the ratio of the rise of the line to the run of the line, which is, the change in y over the change in x.
Referring to the image attached below, the blue line in the given graph shows the rise of the line while the red line shows the run of the line.
Therefore:
Rise of the line = 2 units
Run of the line = 2 units
Slope of the line (m) = rise/run = 2 units/2 units

Answers
Given:
Numbers in the container: All integers from 10 to 50
Let's find P(Prime numbers| numbers between 11 and 30).
Here, we are to find the conditional probability.
Apply the formula:
P(Prime|between 11 and 30) = P(prime numbers and between 11 and 30) ÷ P(numbers between 11 and 30).
Where:
• Prime numbers between 11 and 30 = 11 , 13 , 17 , 19 , 23 , 29 =6 numbers
,• Intergers from 10 to 50 = 41 integers.
To find the probability, we have:
[tex]\begin{gathered} P(Prime|between11and30)=\frac{\frac{6}{41}}{\frac{20}{41}} \\ \\ =\frac{6}{41}\ast\frac{41}{20} \\ \\ =\frac{6}{20} \\ \\ =\frac{3}{10} \end{gathered}[/tex]Therefore, we have:

a street light is at the top of a ft. tall pole. a man ft tall walks away from the pole with a speed of feet/sec along a straight path. how fast is the tip of his shadow moving when he is feet from the pole?
Answers
[tex]\frac{dx}{dy} = \frac{5}{3}. 4\frac{ft}{s} = \frac{20}{3}\frac{ft}{s}[/tex] is moving at the speed of the shadow
x is the distance from the man to the pole, and y is the distance from the tip of the man's shadow to the pole. I assume the man and pole are standing straight up, which means the two cases are similar.
[tex]\frac{y-x}{y} = \frac{6}{15}[/tex]
15(y-x) = 6y
9y = 15x
[tex]\frac{5}{3}x\\[/tex] = y
differentiate both sides with respect to t or time.
[tex]\frac{dx}d{y} = \frac{5}{3}\frac{dx}{dt}[/tex]
you know [tex]\frac{dx}{dy} = 4\frac{ft}{s}[/tex] because the man is walking that speed away from the pole. you want to find [tex]\frac{dx}{dy}[/tex] , how fast the tip of the shadow is moving.
that means
[tex]\frac{dx}{dy} = \frac{5}{3}. 4\frac{ft}{s} = \frac{20}{3}\frac{ft}{s}[/tex]

How do I find the slope and Y-intercept of the line x+2y=-2
Answers
slope = -1/2
y-intercept = (0, -1)
Explanation:Given:
[tex]x\text{ + 2y = - 2}[/tex]To find:
the slope and the y-intercept
To determine the slope we will use the linear function formula:
[tex]\begin{gathered} y\text{ = mx + b} \\ m\text{ = slope} \\ b\text{ = y-intercept} \end{gathered}[/tex]We need to rewrite the given equation in the form above so as to get the slope
[tex]\begin{gathered} x\text{ + 2y = -2} \\ 2y\text{ = -x - 2} \\ y\text{ = -}\frac{x}{2}\text{ - }\frac{2}{2} \\ y\text{ = }\frac{-x}{2}-1 \end{gathered}[/tex]From the above, m = -1/2
Hence, the slope is -1/2
The y-intercept is the value of y when x = 0
To get the y-intercept, we will substitute x with 0:
[tex]\begin{gathered} y\text{ = }\frac{-0}{2}\text{ - 1} \\ y\text{ = 0 - 1} \\ y\text{ = -1} \\ \\ The\text{ y-intercept in ordered pair \lparen x, y\rparen:} \\ when\text{ x = 0, y = -1} \\ y-\text{ intercept = \lparen0, -1\rparen} \end{gathered}[/tex]For the cented functions g(x) = x + 3 and h(x) = (x-4, find the composition gºh and specify its domain using interval notation,

Answer
Part A
(g o h)(x) = x - 1
Part B
Domain of (g o h) = (-∞, ∞)
Explanation
Part A
We are given that
g(x) = x² + 3
h(x) = √(x - 4)
We are then asked to find (g o h)(x)
To do that, we need to note that (g o h)(x) means we write g(x), but instead of x, we write h(x). That is,
(g o h)(x)
= g(h(x))
= [h(x)]² + 3
= [√(x - 4)]² + 3
= x - 4 + 3
= x - 1
Part B
To find the domain
The domain of a function refers to the values of the independent variable (x), where the dependent variable [y or f(x)] or the function has a corresponding real value. The domain is simply the values of x for which the output also exists.
And for (g o h)(x) = x - 1, we know there will be an answer for all real number values of x. Hence,
Domain = (-∞, ∞)

Answers
1) How many ways can 4 candy bars be chosen from a store that sells 30 candy bars?
In this case we can combine 30 types of candy bars in a set of 4 bars.
This can be calculated as a combination of 30 in 4 with no repetition:
[tex]\begin{gathered} C(n,r)=\frac{n!}{(n-r)!r!} \\ C(30,4)=\frac{30!}{(30-4)!4!}=\frac{30!}{26!4!}=\frac{30\cdot29\cdot28\cdot27}{4\cdot3\cdot2\cdot1}=\frac{657720}{24}=27405 \end{gathered}[/tex]Answer: 27,405 possible combinations (C).
2) How many ways can 13 students line up for lunch?
In this case we have a permutation of 13 in 13 with no repetition.
We can calculate this as:
[tex]\begin{gathered} P(n,r)=\frac{n!}{(n-r)!} \\ P(13,13)=\frac{13!}{(13-13)!}=\frac{13!}{1}=6227020800 \end{gathered}[/tex]Answer: 6,227,020,85)00 possible permutations (P).
3) How many ways can you make a 3-letter arrangements out of the letters in the word TRAPEZOID.
In the word we have 9 letters with no repetition, so we have to calculate a permutation (as order matters) of 9 letters in 3 places.
We can calculate this as:
[tex]P(9,3)=\frac{9!}{(9-3)!}=\frac{9!}{6!}=9\cdot8\cdot7=504[/tex]Answer: 504 possible permutations (P).
4) How many ways can you choose 2 books from a shelf of 40 books.
In this case, the order does not matter, so it is a combination of 40 in 2.
This can be calculated as:
[tex]C(40,2)=\frac{40!}{(40-2)!2!}=\frac{40!}{38!2!}=\frac{40\cdot39}{2\cdot1}=\frac{1560}{2}=780[/tex]Answer: 780 possible combinations (C)
5) How many ways can 12 swimmers finish in first, second, and third place?
In this case, the order does matter, so we have a permutation of 12 in 3:
[tex]P(12,3)=\frac{12!}{(12-3)!}=\frac{12!}{9!}=12\cdot11\cdot10=1320[/tex]Answer: 1320 permutations (P)
6) How many ways can Mrs. Sullivan choose two students from 27 to help put away calculators at the end of class?

A machine in a factory makes 2 1/4 pounds of nails in 1 1/2 hours. At what rate, in
pounds per hour, does the machine make nails? Show your work.
Answers
The rate of pounds per hour of the machine is 1.5 pounds per hour
How to determine the rate of pounds per hour?From the question, we have the following parameters:
Pounds of nails = 2 1/4 pounds of nail
Number of hours = 1 1/2 hour
From the above parameters, the rate of pounds per hour can be calculated using the following formula of constant of proportionality
The constant of proportionality is calculated as
Constant of proportionality = Pounds of nails/Number of hours
In this case, we have
Rate of pounds per hour = Pounds of nails/Number of hours
Substitute the known values in the above equation
Rate of pounds per hour = (2 1/4)/(1 1/2)
So, we have
Rate of pounds per hour = 1.5
Hence, the rate is 1.5 pounds per hour

A local movie theater sells tickets at different prices for an adult and for a child. The price of an adult’s ticket is $10.50 and the price of a child’s ticket is $6.50 . If the theater sells a total of 65 tickets for a total price of $594.50 in an afternoon, how many child tickets did the theater sell?
Answers
Answer:
6.50 × 65 tickets.
Answer = $422.5
The theater sells 43 adult tickets and 22 child tickets.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let us assume,
The number of adult tickets sold is x
The number of tickets sold for children is y
Since the total number of tickets sold is 65,
x + y = 65 .....(i)
Charge per adult ticket=$10.50,
So the amount collected by selling adult tickets is 10.50×x
Charge per child ticket=$6.50,
So the amount collected by selling tickets for children is 6.50×y
We know that the total amount earned by the theater is $594.50
So, 10.5x +6.5y = 594.50 ......(ii)
After solving equations (i) and (ii), we get the values of x and y as
x = 43 and y = 22
Therefore, the theater sells 43 adult tickets and 22 child tickets.

The measure of the lableled angles are x = 202 and (x - 44) = 158
What are the values of the labeled angles?Before we can solve this question, we need to understand the geometry of the shape.
The shape we have here is a pentagon. The sum of angles in a pentagon is 540. The angle with a red square is a right angle and the value is 90.
Therefore:
x + 90 + 90 + (x - 44) = 540
x + 180 + x - 44 = 540
2x + 136 = 540
2x = 540 - 136
2x = 404
x = 404/2
x = 202
Also:
(x - 44) = 202 - 44 = 158
Therefore, the angles x and (x - 44) measure 202 and 158 respectively.

The unknown angle in the triangle is as follows;
∠H = 38 degrees.How to find angles in a triangle?The angle H can be found using the exterior angle theorem.
The exterior angle theorem states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.
In other words, an exterior angle of a triangle is equal to the sum of the two opposite interior angles.
Hence,
∠DFG = ∠G + ∠H
∠DFG = 14x + 1
∠G = 89°
∠H = 5x - 7
14x + 1 = 89 + 5x - 7
14x + 1 = 89 - 7 + 5x
14x - 5x = 89 - 7 - 1
9x = 81
divide both sides by 9
x = 81 / 9
x = 9
Therefore,
∠H = 5(9) - 7 = 45 - 7 = 38 degrees.

.The bicycle costs $250.
Eva already has $125 saved.
She plans on washing cars for $25 per car.
Ereed wash c cars to have enough to purchase the bicycle.
Select the 3 orrect equations below that can be used to represent when she will be able to purchase the bicycle she wants
Answers
The correct equations which can be used to represent when she will be able to purchase the bicycle she wants are:
250 = 125+25c125 = 25cc = 5Given, Eva wants to buy a bicycle.
The cost of bicycle is = $250
Saving's of Eva = $125
Eva plans on washing cars for $25 per car.
Eva wash 'c' cars to have enough to purchase the bicycle.
cost of bicycle = saving's of Eva + Eva washing 'c' cars for $25 per car.
⇒ 250 = 125 + 25c
arrange the like terms on one side.
⇒ 250 - 125 = 25c
⇒ 125 = 25c
⇒ 25c = 125
⇒ c = 125/25
⇒ c = 5
hence Eva washes 5 cars to earn $125 which gets added to the savings and becomes the cost of the bicycle she wants to purchase.
⇒ cost of bicycle = 125+25(5)
⇒ cost of bicycle = 125+125
⇒ cost of bicycle = $250
Hence we got the required answers.
