The length of a rectangle is three times its width.
If the perimeter of the rectangle is 80 find its length and width.
The length is 30 unit and width is 10 unit.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
length of a rectangle is three times its width.
Perimeter of the rectangle = 80
let the width be x then length = 3x
So, Perimeter of the rectangle = 80
2( x+ 3x) = 80
4x= 40
x= 10

Iker runs laps on the track each week and increases what he runs by the same amount each Saturday. He began by running 24 laps and on the next Saturday he ran 35. A) How many laps did he start running?
b) How many more laps did he run each week?
c) Write the equation for this situation that models this type of growth:
A) Iker started running 24 laps on the track each week. This is mentioned in the question.
B) Iker ran 11 more laps each week.
C) The equation for this situation would be: y = 11x + 24
Determine the number of lapsTo find out how many more laps he ran each week, we can subtract the number of laps he ran on the first week from the number of laps he ran on the second week: 35 - 24 = 11 So, Iker ran 11 more laps each week.
To write an equation that models this type of growth, we can use the following formula: y = mx + b
Where y is the number of laps he runs, m is the number of additional laps he runs each week, x is the number of weeks, and b is the number of laps he started running.
In this case, m = 11 (the number of additional laps he runs each week) and b = 24 (the number of laps he started running).
So the equation for this situation would be: y = 11x + 24 This equation shows that the number of laps Iker runs each week (y) is equal to 11 times the number of weeks (x) plus the number of laps he started running (24).

Step-by-step explanation:Simple interest is the amount of money earned based on the initial amount invested.
Simple Interest Formula
The formula for simple interest is A = P(1 + rt). Let's define each of these variables.
A is the total amount of money in the accountP is the principal or the initial amount depositedr is the interest rate expressed as a decimalt is time in yearsTo solve for simple interest, we need to plug in the information we are given.
Solving Simple Interest
In the question, we're told that $3000 is the initial amount deposited, so P = 3000. The rate is 2%, which means that r = 0.02. Also, this interest is earned over 10 years, thus t = 10. Now, plug this into the formula above.
A = 3000(1 + 0.02*10)Then, just simplify the right side of the equation.
A = 3000(1 + 0.2)A = 3000 * 1.2A = 3600This means that after 10 years, there will be a total of $3600 in the account.

1) Chelsea and Matt each improved their yards by planting daylilies and ivy. They bought their
supplies from the same store. Chelsea spent $81 on 1 daylily and 8 pots of ivy. Matt spent $189
on 10 daylilies and 11 pots of ivy. Find the cost of one daylily and the cost of one pot of ivy.
Answer:
One daylily costs $9, and one pot of ivy costs $9.
Step-by-step explanation:
Step 1: Write a System of Algebraic Equations
We are given 2 different variables, or "unknowns", that we need to find the value of here - the cost of one daylily, and the cost of one pot of ivy. We know that the cost of each plant remains constant (doesn't change), and we are given the following information:
1 daylily and 8 pots of ivy cost $81.10 daylilies and 11 pots of ivy cost $189.We can see that we have a system of equations in the making. The first thing to do when writing a system is assign letters to variables. Let's let the cost of one daylily be denoted as [tex]d[/tex], and the cost of one pot of ivy be denoted as [tex]i[/tex] (in dollars for each). From the above information, we can write the system:
[tex]d+8i=81 \hspace{0.8cm} (1)\\10d+11i=189 \hspace{0.1cm} (2)[/tex]
Step 2: Solve the System (with Substitution)
Now that we have a solution, let's use it to solve for the value of each variable. There are many ways to do this (addition, subtraction, etc), but it seems that the quickest way to solve this particular system is using the substitution method. This is where you write one variable in terms of the others by manipulating one equation, and then substituting that expression in for the isolated variable in the other equation. It's easy to do this here because we already have a [tex]d[/tex] in (1).
Isolating [tex]d[/tex] in (1) by subtracting [tex]8i[/tex] from both sides, we get:
[tex]d+8i=81\\d=81-8i\hspace{0.5cm} (3)[/tex]
Substituting (3) into (2) and solving for i, we get:
[tex]10d+11i=189\\10(81-8i)+11i=189\\810-80i+11i=189\\810-69i=189\\-69i=-621\\\bf i=9[/tex]
Substituting this value into (3), we get:
[tex]d=81-8i\\=81-8*9\\=81-72\\=\bf9[/tex]
Therefore, one daylily costs $9, and one pot of ivy costs $9.
name the point of concurrency of the angle bisectors
The point of concurrency of the angle bisectors is called the incenter. The incenter is the center of the incircle of a triangle, which is the largest circle that can be inscribed within the triangle.
The center present in the largest circle that can be inscribed in the triangle is defined as incircle. It is in the equal distance from all the sides present in the triangle , which makes it unique comparing to others.
The line that bisects the angle which is also called as angle bisector is one of the method to find the incenter. It divide the entire triangle into three triangles of same area and length. The triangle includes three bisectors to each angle.
These bisectors are intersected at the same point in the triangle , which is also termed as incenter of the triangle. This is because the incenter is in equal distance from each of the every side of the triangle, and this makes the angle bisectors to divide the triangle into parts which makes the incenter equidistant from all three sides of the triangle.

The function represents g(c) a reflection of ff(c) = 6 (1/3)ˣ across the y axis is g(c) = -6(1/3)⁻ˣ and option B is the correct answer.
What is reflection of a function?A function can be transformed by flipping its graph around an axis, which is known as a reflection function. Reflecting or reflection in mathematics, and more precisely in geometry, refers to flipping. Hence, a function's reflection is essentially the mirror image of the supplied function or graph. As a result, reflecting functions are a common name for them.
The given function is: f(c) = 6 (1/3)ˣ.
When a function is reflected along the y-axis the coordinates of the graph change as follows:
(x, y) → (-x, y)
The function f(c) = 6 (1/3)ˣ when reflected will have the function g(c) as:
g(c) = -6(1/3)⁻ˣ
Hence, the function represents g(c) a reflection of ff(c) = 6 (1/3)ˣ across the y axis is g(c) = -6(1/3)⁻ˣ and option B is the correct answer.

The point G( – 5, – 1) is rotated 180° counterclockwise around the origin. What are the coordinates of the resulting point, G'?
Answer:
the coordinates of the resulting point G' are (5, 1).
Step-by-step explanation:
When a point is rotated 180° counterclockwise around the origin, it is reflected across the x-axis and y-axis. This means that the x-coordinate and y-coordinate of the point are both negated.
So, for the point G(-5, -1), the x-coordinate becomes -(-5) = 5 and the y-coordinate becomes -(-1) = 1.
Answer:
(5,1)
Step-by-step explanation:
Rotating 180 degrees about the origin means that there is a reflection against the y-axis and x-axis. Therefore, the x and y values will change their signs.
Hence, the new coordinate would be (5,1)

The solution to the system of equations is x = 35/9 and y = -20/27.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
I assume the second equation is supposed to be equal to zero, so the system of equations is:
-2x + 3y = -10
-7x + 3y = -25
To solve this system of equations using elimination, we can add the two equations together. This will eliminate the y variable and give us an equation in terms of x:
-2x + 3y + (-7x + 3y) = -10 - 25
-9x = -35
x = 35/9
Now that we know x, we can substitute it into either equation to solve for y. Let's use the first equation:
-2x + 3y = -10
-2(35/9) + 3y = -10
-70/9 + 3y = -90/9
3y = -20/9
y = -20/27
Therefore, the solution to the system of equations is x = 35/9 and y = -20/27.

I know that the first term of the sequence is -2, and the fifth term is -1/8. What do you know?Type of sequence : Common ratio or difference : Explicit equation : Recursive equation :
Answer:
Type of sequence: Geometric
Common ratio: [tex]\mbox{\large \dfrac{1}{2}}[/tex]
Explicit equation:
[tex]a_n = a_1 \cdot \left(\dfrac{1}{2}\right)^{n-1 }[/tex]
Recursive Equation:
[tex]\mbox{\large a_n = \dfrac{1}{2} \cdot a_{n-1}}[/tex]
Step-by-step explanation:
Looking at the first and fifth terms it appears to be a geometric sequence where each successive term is r x previous term
r is referred to as the common ratio = aₙ/aₙ₋₁ where aₙ is the nth term and aₙ₋₁ the previous term
The nth term can be found by using the formula
aₙ = a₁ x rⁿ⁻¹
where a₁ is the first term
We have a₁ = -2
a₅ = - 1/8
Plugging these into the general equation for a geometric sequence we get
[tex]-\dfrac{1}{8} = -2 \cdot r^{5-1}\\\\\\-\dfrac{1}{8} = -2 \cdot r^{4}\\\\r^4 = -\dfrac{1}{8} \div -2\\\\\\r^4 = \dfrac{1}{16}\\\\\\r = \sqrt[4]{\dfrac{1}{16}} \\\\r = \dfrac{1}{2} \;\;\;\;\textrm(since \; 2^4 = 16)[/tex]
Recursive equation relates the nth term to the (n-1)th term and is
[tex]a_n = \dfrac{1}{2} \cdot a_{n-1}[/tex]
If we start at the first term
a₁ = -2
a₂ = 1/2 x (-2) = - 1
a₃ = 1/2 x (-1) = - 1/2
a₄ = 1/2 x (-1/2) = -1/4
a₅ = 1/2 x (-1/4) = - 1/8
So everything pans out fine
Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A) = 0.30 and P(B) =0.40.
1. What is P(A B)?
2. What is P(A | B)?
3. Is P(A | B) equal to P(A)?
4. A student in statistics argues that the concepts of mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent. Is this statement accurate?
5. What general conclusion would you make about mutually exclusive and independent events given the results of this problem?
1) The value of P(A∩B) = 0.
2) The value of P(A|B) = 0.
3) P(A|B) is not equal to P(A). A and B are independent events.
4) The statement "Mutually exclusive events and independent events are really the same, and that if events are mutually exclusive they must be independent." is not accurate.
5) We can conclude that mutually exclusive events have a probability of intersection of zero and are not independent.
1) Since A and B are mutually exclusive, they cannot occur at the same time, so P(A∩B) = 0.
2) The conditional probability of A given B is defined as the probability of A occurring given that B has occurred. Since A and B are mutually exclusive, if B has occurred, then A cannot occur. Therefore, P(A|B) = 0.
3) No, P(A|B) is not equal to P(A). Since B has occurred, the sample space has been reduced to only those outcomes in which B has occurred. Therefore, the probability of A given that B has occurred can only be determined from the portion of the sample space in which both A and B occur.
However, since A and B are mutually exclusive, this probability is zero. Therefore, P(A|B) ≠ P(A).
4) The statement is not accurate. Mutually exclusive events and independent events are different concepts. Two events are mutually exclusive if they cannot occur at the same time, whereas two events are independent if the occurrence of one event does not affect the probability of the other event.
If two events are mutually exclusive, they are not independent because the occurrence of one event precludes the occurrence of the other event.
5) Mutually exclusive events have a relationship where if one event occurs, the other cannot. In contrast, independent events are events where the occurrence of one event does not affect the probability of the other event occurring.
Therefore, we can conclude that mutually exclusive events and independent events are not the same concept, and we must be careful not to confuse them.

find the surface area of a Sphere of diameter
36 cm. tak x=22 7
Answer: The surface area of a sphere can be calculated using the formula:
A = 4 * π * r^2
Where r is the radius of the sphere.
The diameter of the sphere is 36 cm, so the radius can be found by dividing the diameter by 2:
r = 36 cm / 2 = 18 cm
Now that we have the radius, we can plug it into the formula:
A = 4 * π * r^2 = 4 * π * (18 cm)^2 = 4 * π * 324 cm^2 = 1296 * π cm^2
Since π is approximately equal to 3.14, we can get an approximate answer:
A ≈ 1296 * 3.14 = 4071.84 cm^2
So the surface area of the sphere with a diameter of 36 cm is approximately 4071.84 square centimeters.
