The number of cows are 9 and the number of chickens are 13.
Given that, a farm has 22 cows and chicken altogether.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Let the x be the number of cows and y be the number of chicken.
Now, x+y=22 -------(I)
The farmer counted 62 legs total.
So, 4x+2y=62 -------(II)
Multiply equation (I) by 2, we get
2x+2y=44 -------(III)
Subtract equation (III) from equation (II), we get
4x+2y-(2x+2y)=62-44
⇒ 2x=18
⇒ x=9
Substitute x=9 in equation (I), we get
9+y=22
⇒ y=13
Hence, the number of cows are 9 and the number of chickens are 13.

Assuming that a personal space is 3ft squared. Estimate how many people can fit into a circular arena a diameter of 100 yards?
Answer
2617.
Step-by-step explanation
To estimate the number of people that can fit into a circular arena with a diameter of 100 yards, we first need to find the area of the arena. To do this, we can use the formula for the area of a circle, which is equal to pi times the radius squared. Since the diameter of the arena is 100 yards, the radius would be half of that, or 50 yards. Plugging this value into the formula for the area of a circle, we get:
Area = pi * 50^2
Since pi is approximately equal to 3.14, we can plug this value into the equation to get:
Area = 3.14 * 50^2
This simplifies to:
Area = 3.14 * 2500
Which gives us an area of approximately 7850 square yards.
Since one person requires a personal space of 3 square feet, we can divide the total area of the arena by 3 to find the number of people that can fit in the arena. This gives us:
7850 square yards / 3 square feet/person = 2616.666... people
Rounded to the nearest whole number, this means that approximately 2617 people could fit in the circular arena with a diameter of 100 yards.

Write and find the general solution of the differential equation that models the verbal statement. Evaluate the solution at the specified value of the independent variable.
The rate of change of P is proportional to P. When t = 0, P = 8,000 and when t = 1, P = 5,200. What is the value of P when t = 6?
Be sure to:
1) Write the differential equation (use k for the constant of proportionality)
2)Solve the differential equation
3) Evaluate the solution at the specified value of the independent variable. (Round your answer to three decimal places.)
1) The differential equation is: dP/dt=kP
2) P(t)=8000[tex]e^{-0.28t}[/tex]
3) The solution at the specified value of the independent variable is 1490.991
What is meant by differential equation?In practical contexts, derivatives frequently represent the rates of change of physical quantities, and the differential equation establishes a relationship between the two. As a result of the frequent occurrence of these correlations, differential equations are widely employed in a wide range of disciplines, including engineering, physics, economics, and biology.
Only the simplest differential equations can be resolved explicitly, but many aspects of a given differential equation's solutions can be determined without doing an exact calculation.
1) The differential equation is: dP/dt=kP
Here k is the proportionality constant
2) Now, we have to solve the differential equation on dP/dt=kP
∫dP/P=∫kdt+lnP₀
lnP₀=kt+lnP₀
lnP/P₀=kt
P=P₀[tex]e^{kt}[/tex]
Here P₀ is the constant of integration.
P(t)=P₀[tex]e^{kt}[/tex]
And they have given that,
P(0)=8000=P₀e⁰
P₀=8000
P(1)=5200
5200=8000[tex]e^{k}[/tex]
k=-2log(2)+log(3)≈ -0.28
Therefore, the required function is:
P(t)=8000[tex]e^{-0.28t}[/tex]
3) Now, we have to put t=6 in the above equation:

f) No.
What is an expression?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
Given that
the number of yellow tile in figure 1 is 8.
The number of yellow tile in figure 2 is 12.
The number of yellow tile in figure 3 is 16.
(a) The table is
Figure 1 2 3
Number of tiles 8 12 16
(b)
The number of tiles increase at a constant rate.
The rate is (12 - 8) = (16 - 12) = 4
The relation with the figure and number of tiles is
The number of tiles is = 4 + (the number of figure - 1)4
C)
Assume that y represents total number of tiles.
x = Number of figure
Rewrite "The number of tiles is = 4 + (the number of figure - 1)4" in term of x and y:
y = 8 +(x - 1)4
y = 8 + 4x -4
y = 4x + 4
d) Putting x = 24 in y = 4x + 4
y = 4×24 + 4
y = 96 + 4
y = 100
e)
Putting y = 176 in y = 4x + 4
176 = 4x + 4
Subtract 4 from both sides:
172 = 4x
Divide both sides by 4
x = 43
f)
Putting y = 54 in y = 4x + 4
54 = 4x + 4
Subtract 4 from both sides:
50 = 4x
Divide both sides by 4
x = 50/4
The value of x is not a whole number. Thus it is not possible that a figure has with 54 yellow tiles.

Robin worked his 40 regular hours last week plus 20 overtime hours at the time-and-a-half rate. His gross pay was $16,203. What is his regular hourly rate?
Answer:
His rate is a whopping $231.47 per hour.
:)
Step-by-step explanation:
We can conclude that.
[tex]r*t_1=p_{reg}[/tex] is the gross pay from his regular hours.
[tex]1.5r*t_2=p_{ovt}[/tex] is the gross pay from his overtime hours.
So all together we can say
[tex](r*t_1)+(1.5r*t_2)=p[/tex]
We are looking for his hourly rate.
Lets solve for [tex]r[/tex].
Multiply the terms in the parenthesis.
[tex]rt_1+1.5rt_2=p[/tex]
Factor [tex]r[/tex] out of [tex]rt_1[/tex].
[tex]r(t_1)+1.5rt_2=p[/tex]
Factor [tex]r[/tex] out of [tex]1.5rt_2[/tex].
[tex]r(t_1)+r(1.5t_2)=p[/tex]
Factor [tex]r[/tex] out of [tex]r(t_1)+r(1.5t_2)[/tex].
[tex]r(t_1+1.5t_2)=p[/tex]
Divide each term in [tex]r(t_1+1.5t_2)=p[/tex] by [tex]t_1+1.5t_2[/tex] and simplify.
[tex]\frac{r(t_1+1.5t_2)}{t_1+1.5t_2} =\frac{p}{t_1+1.5t_2}[/tex]
Simplify the left side. Cancel the common factor of [tex]t_1+1.5t_2[/tex]
[tex]r=\frac{p}{t_1+1.5t_2}[/tex]
Now we have an equation to find his regular hourly rate.
We are given
[tex]p=16203[/tex]
[tex]t_1=40[/tex]
[tex]t_2=20[/tex]
Lets plug these numbers into our equation for [tex]r[/tex].
[tex]r=\frac{16203}{40+1.5*20}[/tex]
[tex]r=\frac{16203}{70}[/tex]

Using the exponent's rule we know that x = 5.
What are exponents?Exponentiation is a mathematical process that involves the base b and the exponent or power n.
It is represented as bn and is pronounced as "b to the n."
A number's exponent indicates how many times to multiply that particular number.
It appears as a little number above and to the right of the basic number.
For instance, 82 = 8 x 8 = 64.
(The exponent "2" instructs us to multiply by two and use the number eight.)
Another illustration is 53 = 5 * 5 * 5 = 125.
So, we have: 2ˣ = 32
We know that:
2 * 2 * 2 * 2 * 2 = 32
2 is multiplied 5 times which means:
2⁵ = 32
Hence, x = 5.
Therefore, using exponents we know that x = 5.

What are linear models?
A response variable can be described in terms of a linear combination of predictor variables using linear models. The response ought to be continuous and at least roughly regularly distributed. Although these models are widely used, they are unable to handle clearly discrete or skewed continuous data.
In the table, we see that as x increases, y values change in a steady manner. The slope of this function is approximately 1860.
We use straight lines to visually illustrate linear relationships. Typically, a linear model has two parameters: the slope, also known as the growth factor or rate of change, and the y-intercept, often known as the beginning value. The linear model can be expressed as a linear function, y = mx + b or y=mx+b, where m is the slope and b is the y-intercept.
