Step-by-step explanation:
We must write an equation for Duke's expenses and an equation to represent Tennessee's expenses.
For Duke expenses we have:
A fixed expense of $ 111.60 per year
A variable expense of $ 4.00 for each movie.
The equation that represents the expenses is a linear equation like the one shown below
[tex]C = 111.60 + 4.00x[/tex]
Where C represents the cost and x the number of movies.
For Tennessee expenses we have:
A variable expense of $ 16.40 for each film.
The equation that represents the expenses is a linear equation like the one shown below
[tex]C = 16.40x[/tex]
Where C represents the cost and x the number of movies.
To know after how many movies have paid the same amount, we equate both equations and solve the variable x
[tex]111.60 +4.00x=16.40x\\\\16.40x - 4x = 111.60\\\\12.40x =111.60\\\\x =\frac{111.60}{12.40}\\\\x =9[/tex]
After 9 movies they will have paid the same amount
A landing pad for a helicopter is in the shape of a circle with a radius of 7 meters. Which of the following is closest to the area of the landing pad?
Answer:
The approximate value of the area is [tex]153.86\ m^{2}[/tex]
Step-by-step explanation:
we know that
The area of the circle (landing pad) is equal to
[tex]A=\pi r^{2}[/tex]
we have
[tex]r=7\ m[/tex]
substitute
[tex]A=\pi (7)^{2}[/tex]
[tex]A=49\pi\ m^{2}[/tex] ----> exact value of the area
Find the approximate value
assume [tex]\pi=3.14[/tex]
[tex]A=49(3.14)=153.86\ m^{2}[/tex] ------> approximate value of the area
Answer:
Area of Circular landing pad = 307.72 m^2
Step-by-step explanation:
Area of Circular landing pad = 2πr^2
where r = radius of circular landing pad = 7m
π = 22/7 = 3.14
by placing all these value in the formula
Area of Circular landing pad = 2*3.14*(7^2)
Area of Circular landing pad = 6.28*49
Area of Circular landing pad = 307.72 m^2

1.3
1.8
2.9
3.5
Answer:
1. 52
2. 2.9
Step-by-step explanation:
To find the mean, we take all the numbers, add them up then divide by the number of numbers.
1. mean height
mean = (50+54+52+56+48)/5
=260/5
=52
52 inches
2. mean score
There are 5+3+12+2+6+6+4 students = 38 students
Multiply the number of students times the score and add together
total points = (0*5+1*3+2*12+3*2+4*6+5*6+6*4)
= 111
The mean is the total points divided by the number of students
mean = 111/38
=2.92
Answer:
[tex]\bar x = 52inch\\\bar x_w = 2.92[/tex]
Step-by-step explanation:
According to the data recorded in the table, the average of the students' heights is calculated with the expression for the arithmetic mean:
[tex]\bar x =\frac{1}{n} \sum x_i[/tex]
[tex]\bar x = \frac{1}{5}(48 + 50 + 52 + 54 + 56) = \frac{260}{5} = 52[/tex]inch.
In the same way, the weighted average must be used to find the average football score:
[tex]\bar x_w = \frac{\sum x_i * w_i}{\sum w_i}[/tex], where wi are the frequencies of each response.
[tex]\bar x_w = (0 * 5 + 1 * 3 + 2 * 12 + 3 * 2 + 4 * 6 + 5 * 6 + 6 * 4) / (5 + 3 + 12 + 2 + 6 + 6 + 4) = \frac{111}{38} = 2.92[/tex]

f(x) = x3 − 2x2 − x + 2 Factor: x-2
f(x) = -x3 + 13x − 12 Factor: x+4
Step-by-step explanation:
f(x) = x^3 − 3x^2 − 13x + 15
Solving:
We will use rational root theorem: -1 is the root of x^3 − 3x^2 − 13x + 15 so, factor out x+1
x^3 − 3x^2 − 13x + 15 / x+1 = x^2-2x-15
Factor: x^2-2x-15 =(x+3)(x-5)
So, factors are: (x+1)(x+3)(x-5)
Factor: (x+5)
f(x) = x^4 + 3x^3 − 8x^2 + 5x − 25
Solving:
We will use rational root theorem: -5 is the root of x^4 + 3x^3 − 8x^2 + 5x − 25, so factour out (x+5)
x^4 + 3x^3 − 8x^2 + 5x − 25 / x+5 = x^3-2x^2 +2x -5
So, factors are (x+5) (x^3-2x^2 +2x -5)
Factor: x+5
f(x) = x^3 − 2x^2 − x + 2
Solving:
x^2(x-2)-1(x-2)
(x-2)(x^2-1)
(x-2) (x-1) (x+1)
Factor: x-2
f(x) = -x^3 + 13x − 12
Solving:
-(x^3 + 13x -12)
We will use rational root theorem:
The 1 is a root of (x^3 + 13x -12) so, factor out x-1
Now solving (x^3 + 13x -12)/x-1 we get (x-3)(x+4)
So, roots are: - (x-1)(x-3)(x+4)

What is the value of discriminant in the equation shown below? x2+3x-6=0
ANSWER
The discriminant is -3
EXPLANATION
The given quadratic equation is:
[tex] {x}^{2} + 3x - 6 = 0[/tex]
Comparing this equation to:
[tex]a {x}^{2} + bx + c = 0[/tex]
we have
a=1, b=3, and c=-6
The discriminant is calculated using the formula,
[tex]D = {b}^{2} - 4ac[/tex]
We substitute the values to get:
[tex]D = {3}^{2} - 4(1)(3)[/tex]
[tex]D = 9 - 12[/tex]
[tex]D = - 3[/tex]
Answer:
Discriminant = 33
Step-by-step explanation:
Solution of a quadratic equation ax² + bx + c = 0
Discriminant = (b² - 4ac)
It is given that, x² + 3x - 6 = 0
To find the value of discriminant
x² + 3x - 6 = 0
Here a = 1, b = 3 and c = -6
Discriminant = (b² - 4ac)
= (3² - 4 * 1 * (-6))
= (9 +24) = 33
Therefore discriminant of given equation is 33

Rounded back to 42
By using all the chocolate cream, at most the number of eclairs that can be made is:
C) 42
Step-by-step explanation:It is given that:
You have 12 cups of chocolate cream to fill eclairs.
Each eclair requires 2.25 ounces of filling.
We know that:
The universal conversion that is used is:
1 cups=8 ounces
and hence,
12 cups= 12×8=96 ounces.
Hence, the number of ounces of chocolate cream to fill eclairs= 96 ounces
Also,
amount of filling required by 1 eclair= 2.25 ounces.
Hence, Number of eclairs that can be made is:
[tex]Number\ of\ eclairs=\dfrac{96}{2.25}\\\\i.e.\\\\Number\ of\ eclairs=42.67[/tex]
This means that:

School A has 480 students and 16 classrooms. School B has 192 students and 12 classrooms.
How many Students would have to transfer from school Eddie to school be for the ratio of students to classrooms at both schools to be the same explain your reasoning
Answer:96
Step-by-step explanation:
A; 480/16 = 30 students per classroom
B: 192/12 =16 students per classroom
we need x such that [tex]\frac{480-x}{16} = \frac{192+x}{12}[/tex]
which means
(480-x )* 12 should be equal to (192+x) * 16
5,760 - 12x = 3,072+16x
5,760 - 3,072 = 12x + 16x
2,688 = 28x
x = 96
Gina is the costume manager for a large theater company. She has 12 different hats, including 2 helmets.
What is the probability that a randomly chosen hat from Gina's inventory will be a helmet?
Simplify your answer and write it as a fraction or whole number.
The probability that a hat randomly chosen from Gina's inventory will be a helmet is 2 out of 12, which simplifies to 1 out of 6.
Explanation:The subject of this question is probability, which is a branch of mathematics. Gina has 12 different hats, out of which 2 are helmets. The probability of an event happening is calculated as the number of ways the event can happen divided by the total number of outcomes.

Simplify (2√6÷√2+√3)+(6√2÷√6+√3)-(8√3÷√6+√3)
The given expression simplifies to 0.
To simplify the expression (2√6÷√2+√3)+(6√2÷√6+√3)-(8√3÷√6+√3), we need to simplify each term and then combine like terms. Let's break it down step by step:
Simplify 2√6÷√2 by realizing that √6÷√2 is equivalent to √3. So, 2√3 remains.
In the second term, 6√2÷√6, √6÷√6 simplifies to 1, so we just have 6√2.
For the last term, 8√3÷√6, √3÷√6 simplifies to √(3÷6), which simplifies further to √(1÷2), or 8÷√2.
Combine like terms with the common denominator of √3, resulting in:
(2√3 + 6÷√3 - 8÷√3).
The terms with the square root denominators can be combined into (-2√3).
After combining, we have (2√3 - 2√3), which simplifies to 0. Therefore, the simplified expression is 0.

Final answer:
To solve the given system of linear equations, the elimination method is used, resulting in the solution x = 63/26 and y = -97/26.
Explanation:
The system of equations presented by the student:
-4x + 5y = 8
6x - y = 11
belongs to the topic of algebra, specifically to solving systems of linear equations. To find the values of x and y that satisfy both equations, we can use methods like substitution or elimination. Let's use elimination in this case:
Multiply the second equation by 5 so that the y terms will cancel out when we add the two equations together. The second equation becomes 30x - 5y = 55.
Add the modified second equation to the first equation:
-4x + 5y = 8
+ 30x - 5y = 55
____________________
26x = 63
Solving for x, we find that x = 63/26.
Substitute x into one of the original equations to find y.
Using 6x - y = 11:
6(63/26) - y = 11
378/26 - y = 11
y = 378/26 - 286/26
y = 92/26
Therefore, the solution to the system of equations is x = 63/26 and y = 92/26.

3x^2-4x+21
Answer:
The given equation 3x^2-4x+21 has no factors.
Step-by-step explanation:
[tex]3x^2-4x+21[/tex] We need to factorize this equation.
For factorization we split the middle term such that their sum is equal to middle term and product is equal to product of first and last term of the given expression.
in Our case : 63x^2
We need to find two factors of 63x^2 whose sum is equal to -4x
Factors of 63= 1,3,7,9,21,63
1* 63
3*21
7*9
None of the above factors sum is equal to -4.
So, the given equation 3x^2-4x+21 has no factors.
Answer:
No factors.
Step-by-step explanation:
The polynomial is not factorable with rational numbers. If you are on some advanced math, you would be able to be able to factor this.
if x=2 and t=4, what is the value of 1/8 (x^3-4)(t^2+8)
When substituting x=2 and t=4 into the expression 1/8 (x^3 - 4)(t^2 + 8), it simplifies to 12.
If x=2 and t=4, to find the value of 1/8 (x3 - 4)(t2 + 8), we must substitute the values of x and t into the expression and simplify.
Firstly, calculate x3:
x^3 = 23 = 8
Then, calculate t2:
t^2 = 42 = 16
Now we substitute x^3 and t^2 into the expression:
1/8 (8 - 4)(16 + 8) = 1/8 (4)(24) = 1/8 * 96 = 12
Hence, the value of the expression is 12 when x = 2 and t = 4.
Amal drives her car for work.
She claim 40p per mile from her employer.
Amal’s car travels 52 miles for each gallon of petrol.
She pays £5,36 per gallon for petrol.
On one journey Amal drives 260 miles.
For this journey, how much more does she claim than she pays for petrol?
Answer:
£7,878
Step-by-step explanation:
she gets:
40p× 260 miles = 10,400p
she pays:
52 : 5.36= £9.70 per mile
260 x 9.70 = £2,522
to find out what she claimes more than she pays: 10,400 - 2,522 = 7,878
Amal claims £77.2 more than what she spends on petrol for a 260 miles journey for work.
Explanation:To solve this problem, we need to calculate how much Amal earns for the journey and how much she pays for petrol.
First, let's calculate how much she earns: she claims 40p per mile and she drives 260 miles. So, her earnings would be 40p/mile * 260 miles = £104.Next, we determine how much she spends on petrol. Her car travels 52 miles per gallon, and she pays £5,36 per gallon. As the total distance driven is 260 miles, she will need 260 miles / 52 miles/gallon = 5 gallons. Total cost for petrol then is 5 gallons * £5.36/gallon = £26.8.Finally, to determine how much more Amal claims than she spends on petrol we subtract the petrol costs from what she earns: £104 - £26.8 = £77.2.Learn more about Cost Analysis here:https://brainly.com/question/34407434

How can I send a pic of my work
You pess the thing that looks like a paperclip. Then you take a picture and crop it
Please help thx so much
Answer:
(- 1, 3)
Step-by-step explanation:
To find the y- coordinate, substitute x = - 1 into the equation
y - 3 = 2(x + 1) ( add 3 to both sides )
y = 2(x + 1) + 3 ← substitute x = - 1
y = 2(- 1 + 1) + 3 = (2 × 0) + 3 = 0 + 3 = 3
2 friends share 7 cookies equally how many cookies does each person get
3.5 cookies
Friend one: 3 Friend two: 3
One leftover cookie
Split in half give one to each and that makes 3.5
Each of the 2 friends gets 3.5 cookies when sharing 7 cookies equally.
When 2 friends share 7 cookies equally, you divide the total number of cookies by the number of friends. Here, you need to divide 7 cookies by 2 to find out how many cookies each person gets. The calculation would be:
Divide 7 by 2: 7 \/ 2 = 3.5
So, each friend gets 3.5 cookies. However, since you cannot share a cookie perfectly in half without changing its state, we assume this division is hypothetical. In a real-world scenario, they might have to decide how to divide the last cookie or simply share it equally, giving each friend half of the last cookie.
Which algebraic expression will solve for the blue area of this square figure?
A. -12x
B. -2x+30
C. 10x+18
D. 20x
Answer:
Option B. [tex]-2x+30[/tex]
Step-by-step explanation:
we know that
The blue area is equal to the area of complete rectangle minus the area of the white rectangle
so
[tex]A=(5+3x)(6)-(5)(4x)\\\\ A=(30+18x)-(20x)\\ \\A=-2x+30[/tex]

For an equation to be linear, the slope has to be the same/constant.
To find the slope (m), you use the slope formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] and substitute in 2 points
(1 , 60) [x₁ , y₁] and (5 , 70) [x₂ , y₂]
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{70-60}{5-1}[/tex]
[tex]m=\frac{10}{4} =\frac{5}{2}[/tex] or 2.5
Try a different point to see if the slope is the same:
(5, 70) and (20, 80)
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{80-70}{20-5}[/tex]
[tex]m=\frac{10}{15} =\frac{2}{3}[/tex] or 0.6666666
Since the slopes are different, a linear equation can not be used
what measures of the three angles of a triangle are given by 4x,2x, and 6x. what is the measure of the smallest angle?
Answer:
2x=30 degrees
Step-by-step explanation:
Add up all of the angles and set them equal to 180 degrees, because triangles are always made up of angles with a sum of 180 degrees.
2x+4x+6x=180
12x=180
x=15
smallest angle is 2x
2(15)=30
Determine the digits of Y from these clues.
The digits of Y add to 18.
The first digit is 3 times the third digit.
The second digit is 2 times the third digit.
Y is a three digit number.
Answer:
Y = 963
Step-by-step explanation:
The digits of Y add to 18. The first digit is 3 times the third digit. The second digit is 2 times the third digit. Y is a three digit number.
Let Y a three digit number be: abc
First digit = a , Second digit = b, Third digit = c
Also given,
The digits of Y add to 18. => a+b+c = 18 eq(i)
The first digit is 3 times the third digit. => a = 3c eq(ii)
The second digit is 2 times the third digit. => b = 2c eq(iii)
Putting value of a and b in eq(i)
3c + 2c + c = 18
6c = 18
c= 18/6
c = 3
Putting value of c in eq(ii) and eq(iii)
a= 3c => a=3(3) => a= 9
b= 2c => b=2(3) => b = 6
Thus, Y = abc
Y = 963
