The animals I chose are the squrriel and mouse. the linear equation for the squrriel is y = 12x
and for the mouse its y = 8x
Can I please get help with number 4? Im not sure how to graph it
Answers
The linear equation that can be given for squirrel y is the value of 12x.
How to solveAccording to the question,
Animal Mouse Squirrel
Speed(mph) 8 12
SInce "x" the time goes along with x-axis and "y" is the distance covered by the animal.
The mouse time and distance would plot the graph (1,8)(2,16)(3,24)....
The squirrel time and distance would plot the graph (1,12)(2,24)(3,36)....
Let us consider the track is a straight line and the shorter distance is 50 meters.
The formula for straight line equation y = mx + b where 'b' is the base value, 'x' is the time and 'y' is the distance.
The linear equation for squirrel y = 12x+b and the squirrel starts at 0 meters per hour. so the equation becomes y = 12x.
The linear equation for mouse y = 8x + b and the mouse starts at 0 meters. so the equation becomes y = 8x.
Distance covered by the mouse and the squirrel at time x = 3 we can find the distance covered by the mouse and the squirrel.
y =12x
y = 12(3)
y = 36.
The distance covered by the squirrel is 36km at time 3hours.
For mouse, at time x = 3 hours.
y = 8(3)
y=24.
The distance covered by the squirrel is 24km at time 3hours.
Hence, The linear equation for squirrel y = 12x.
The linear equation for mouse y = 8x
The distance covered by the squirrel is 36km at time 3hours.
The distance covered by the squirrel is 24km at time 3hours.

A recipe calls for 14 teaspoons of sugar to make 168 milliliters of coffee what is the constant of proportionality that relates the number of milliliters of coffee made y to the Numbers of teaspoons of sugar used x
Answers
Answer:
Step-by-step explanation:kk
The constant of proportionality that relates the number of milliliters of coffee made y to the number of teaspoons of sugar used x is 12.
Why is that, therefore, if K is the proportionality constant?When two variables are directly or indirectly proportional to one another, their relationship can be represented as y = kx or y = k/x, where k denotes the direction of the relationship between the two variables. It is known as the proportionality constant, or k.
We must determine the ratio of the two amounts in order to determine the constant of proportionality that connects the number of teaspoons of sugar used x to the number of millilitres of coffee brewed y.
Considering the information provided, we understand that:
168 millilitres of coffee require 14 tablespoons of sugar.
As a result, the following is the relationship between the quantity of coffee prepared and the quantity of sugar used in teaspoons:
y/x = 168/14
Reducing the ratio:
y/x = 12
This indicates that 1 teaspoon of sugar is needed to make every 12 millilitres of coffee.
As a result, 12 is the constant of proportionality that links the quantity of coffee created (y) to the quantity of sugar utilised (x).

Bobbi owes a total of $10,455.75 in taxes.
What is taxes?Taxes are compulsory financial charges imposed by governments on individuals or entities based on income, property, or goods/services.
To compute the tax owed by Bobbi, we can use the following steps:
Calculate Bobbi's taxable income by subtracting the standard deduction and personal exemption from her total income:
Taxable income = $68,000 - $6,350 (standard deduction) - $4,050 (personal exemption) = $57,600
Determine the tax bracket in which Bobbi's taxable income falls:
Bobbi's taxable income of $57,600 falls in the 25% tax bracket.
Calculate the tax owed by Bobbi by applying the marginal tax rates to her taxable income. We can use the following formula:
Tax owed = (Taxable income - Previous tax bracket limit) x Marginal tax rate + Previous tax amount
In Bobbi's case, we need to calculate the tax owed in three steps, since her taxable income falls in the 10%, 15%, and 25% tax brackets:
For the first $9,325 of her taxable income, Bobbi owes 10% in taxes:
Tax owed = ($9,325 - $0) x 0.10 + $0 = $932.50
For the next $28,625 of her taxable income (up to $37,950), Bobbi owes 15% in taxes:
Tax owed = ($37,950 - $9,325) x 0.15 + $932.50 = $3,825.75
For the remaining $19,650 of her taxable income (up to $57,600), Bobbi owes 25% in taxes:
Tax owed = ($57,600 - $37,950) x 0.25 + $3,825.75 = $5,697.50

The number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.
The equation h(t) = -16t² + 6t+ 3 models the height of the ball thrown in the air, with h(t) measured in feet and time, t, measured in seconds. The number 3 in this equation refers to the height from which the ball is thrown. This is represented by the constant term 3, which is added to the equation after the sum of the variables. The formula h(t) = -16t² + 6t+ 3 can be broken down into three parts. The first part is the constant term, 3, which denotes the initial height of the ball. The second part is the linear term, 6t, which represents the acceleration of the ball due to gravity. Lastly, the quadratic term, -16t², is used to describe the rate at which the ball’s acceleration slows down due to air resistance. Therefore the number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.

6. Interpret your solution. How many days does it take Amir to catch Jesse? At that time, how many pages have they read? (2 points)
Answers
1. The equation to represent the number of pages Amir has read is y = 35x, where x is the number of days Amir has been reading and y is the number of pages he has read.
2. Let's say that Jesse started reading on Saturday, and Amir started reading on Sunday. If x is the number of days Amir has been reading, then Jesse has been reading for x + 1 days. The equation to represent the number of pages Jesse has read is y = 30(x + 1), where y is the number of pages Jesse has read.
3. The system of equations is:
y = 35x
y = 30(x + 1)
4. We will substitute y in the second equation with y from the first equation. We can do this because both equations represent the number of pages each person has read. So we have:
35x = 30(x + 1)
5. Solving for x:
35x = 30x + 30
5x = 30
x = 6
So it will take Amir 6 days to catch up to Jesse.
To find the number of pages they have read, we can use either of the original equations. If Amir has been reading for 6 days, he has read:
y = 35x = 35(6) = 210 pages
If Jesse has been reading for 7 days (one day more than Amir), he has read:
y = 30(x + 1) = 30(7) = 210 pages
So when Amir catches up to Jesse, they will both have read 210 pages.
6. Amir will catch up to Jesse in 6 days. At that time, they will each have read 210 pages.
Answer: i got number 1 :)
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Then mathematically;
y = 35x
For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)
To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that
Also; y = 30(x + 1)
Equating the two situations
35x = 30(x + 1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 days
This means that it will take Amir 6 days to catch Jese.
The number of books they would have read by then is y = 35x = 30(x + 1)
= 35 * 6 or 30(6+1)

Answers
The ham will bounce to a height of 0.16 meters after the impact.
Define Potential Energy.It is the energy that an object possesses by virtue of its position or configuration, or as a result of its composition. The potential energy of an object can be converted into kinetic energy, which is the energy of motion.
initial potential energy of the ham:
PE = mgh
where m is the mass of the ham, g is the acceleration due to gravity, and h is the initial height from which the ham is dropped. Substituting the given values, we get:
PE = (9.25 lbs)× (1 kg/2.205 lbs) × (9.81 m/s²) × (1.45 m) ≈ 61.8 J
At the moment just before the ham hits the ground, all of this potential energy is converted into kinetic energy:
KE = (1/2)mv²
where v is the velocity of the ham just before impact. Substituting the given values, we get:
KE = (1/2) × (9.25 lbs) × (1 kg/2.205 lbs)×(5.33 m/s)²≈ 87.8 J
After the impact, some of this kinetic energy is lost due to the coefficient of restitution, which is the ratio of the velocity after impact to the velocity just before impact:
e = v'/v
where v' is the velocity after impact. Substituting the given values, we get:
0.35 = v'/5.33
Solving for v', we get:
v' ≈ 1.86 m/s
Now, we can use the conservation of energy to find the maximum height to which the ham bounces. At this point, all of the remaining kinetic energy has been converted back into potential energy:
KE = (1/2)mv'² = mgh'
where h' is the maximum height to which the ham bounces. Substituting the given values, we get:
(1/2) × (9.25 lbs) × (1 kg/2.205 lbs) ×(1.86 m/s)² = (9.81 m/s²) ×h'
Solving for h', we get:
h' ≈ 0.16 m
Therefore, the ham will bounce to a height of approximately 0.16 meters (or 16 centimeters) after the impact.

Which chart has an equation of y = 2.75x?
Answers
Answer:
None of it.
Step-by-step explanation:
Notice the slope is 2.75 this means for EVERY X the graph goes up by 2.75 in the Y axis. For example.
If at X=1 y=0
Then for X=2 y=2.75
and for X=3 y=2.75+2.75=5.5
also the graph must pass thought point (0,0), the origin, and none of the graph follow this.
You can also compare the slopes of each equations
for graph A, from x=1 to x=2 the height Y goes from 3 to 3.5, this is a slope of 0.5 (not the 2.75 we are looking for)
for graph A, from x=1 to x=2 the height Y goes from 1 to 2.5, this is a slope of 1.5 (not the 2.75 we are looking for)
for graph A, from x=1 to x=2 the height Y goes from 1 to 2.75 this is a slope of 1.75 (not the 2.75 we are looking for)
notice the last is similar to equation y=1.75X+b, just in case.

which expression does not belong? explain
Answers
The expression that does not belong with the other three is B. x ² - 8 ˣ because C. The different expression is the one that is not a polynomial.
How to find the expression ?Expression 2 is not a polynomial because it contains a term (8^x) with a variable in the exponent, which is not allowed in a polynomial. All the other expressions are polynomials. This expression therefore does not belong.
Polynomials are mathematical expressions that consist of variables and coefficients, where the variables are raised to non-negative integer powers and the coefficients are constants.
