Answer:
The value of given expression is 1.
Step-by-step explanation:
Consider the given expression is
[tex]\dfrac{e}{4}+2f-3[/tex]
When e=12 and [tex]f=\dfrac{1}{2}[/tex].
Substitute e=12 and [tex]f=\dfrac{1}{2}[/tex] in the given expression.
[tex]\dfrac{12}{4}+2(\dfrac{1}{2})-3[/tex]
On simplification we get
[tex]3+1-3[/tex]
[tex]1[/tex]
Therefore, the value of given expression is 1.
The evaluated result of the expression e/4 + 2f - 3, given specific values e = 12 and f = 5, is 13.
To evaluate the expression e/4 + 2f - 3, we need to follow a systematic procedure. First, we replace 'e' and 'f' with their respective values or expressions, if provided. Once these values are substituted, we perform the mathematical operations in the given order: division, multiplication, and subtraction.
Assuming we have specific values for 'e' and 'f', let's say e = 12 and f = 5. Substituting these values into the expression, we get:
e/4 + 2f - 3
= 12/4 + 2 * 5 - 3
Now, we simplify each part of the expression step by step:
12/4 = 3 (division)
2 * 5 = 10 (multiplication)
3 - 3 = 0 (subtraction)
Summing up the simplified components, we get:
3 + 10 - 0
Finally, performing the remaining additions and subtractions:
3 + 10 = 13
13 - 0 = 13
So, when e = 12 and f = 5, the evaluated result of the expression e/4 + 2f - 3 is 13.

Area = [tex]\frac{5}{12}[/tex] x²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = [tex]\frac{5}{6}[/tex] x and h = x, thus

Suppose that y varies directly with x
and y = 10 when x = 20. What is y
when x = 15?
It’s a fraction
Answer:
15/2
Step-by-step explanation:
y varies directly as x can be written as:
y & x
y = Kx
K = y/x
But from the question, we were told that:
y = 10
X = 20
K = y/x
K = 10/20
K = 1/2
The formula for the expression is:
y = Kx
y = 1/2 x
Now let us solve for y, when:
x = 15
y = 1/2 x
y = 1/2 x 15
y = 15/2
Final answer:
To find the value of y when x = 15, we first determined the constant of proportionality (k) using the given y and x values, which was found to be 0.5. We then plugged x = 15 into the direct variation formula y = kx, resulting in y = 7.5.
Explanation:
If y varies directly with x and y = 10 when x = 20, then we can write this direct variation as y = kx, where k is the constant of proportionality. To find k, we substitute the known values of x and y and solve for k:
10 = k × 20
k = 10 / 20
k = 0.5
With k found, we can now determine what y is when x = 15:
y = k × x
y = 0.5 × 15
y = 7.5

A college student borrows $1500 for 9 months to pay for a semester of school . if the interest is $92.81 find the monthly payment
The monthly payment for the loan of $1500 with $92.81 interest over 9 months is $176.98.
To calculate the monthly payment for a $1500 loan with $92.81 in interest over 9 months, we must first find the total amount to be paid back, which includes both the principal and the interest. The total repayment amount will be $1500 (the original loan) plus $92.81 (the interest), making the total amount $1592.81.
We can then divide this total amount by the number of months the loan will be held to find the monthly payment:
Monthly Payment = Total Repayment Amount ÷ Total Months
Monthly Payment = $1592.81 ÷ 9
Monthly Payment = $176.98
Therefore, the student needs to pay $176.98 every month to pay off the loan in 9 months.
If the 3 longest bulletin boards were side by side, what would their total length be?
The total length of the three longest bulletin boards when placed side by side would be 180 inches.
To calculate the total length of the three longest bulletin boards when placed side by side, we first need to determine the average length of a bulletin board and then multiply it by three.
The length of bulletin boards can vary widely depending on their purpose, but let's assume a standard size commonly found in schools or offices.
A typical bulletin board might measure around 4 feet (48 inches) in length.
However, some bulletin boards can be longer, reaching up to 6 or 8 feet.
Let's take a conservative estimate of 5 feet (60 inches) for our calculations.
So, if we have three bulletin boards each measuring 5 feet (60 inches) in length, the total length when placed side by side would be:
Total length = Length of one bulletin board × Number of bulletin boards
Total length = 60 inches × 3
Total length = 180 inches
Therefore, the total length of the three longest bulletin boards when placed side by side would be 180 inches.
Sanchez applied 6 fluid Ounces of an herbicide per acre on 300 acres of com. How many gallons
did he apply
Click here to enter text.
Answer:
Sanchez applied 1,800 fluid ounces of herbicide to his 300 acres of corn.
Step-by-step explanation:
Let's identify what we already know:
1) Sanchez has 300 acres of corn
2) For every 1 acre, Sanchez applies 6 fluid ounces of an herbicide.
So, we need to figure out how many fluid ounces Sanchez used for the entire six acres. We can create a formula for this:
300 acres x 6 fluid ounces = x
x equals total number of fluid ounces. We multiple the number of acres by the fluid ounces, to get 1,800 fluid ounces for the entire 300 acres of corn.
Final answer:
Sanchez applied a total of 14.0625 gallons of herbicide on 300 acres of corn, after converting the total amount of herbicide from fluid ounces to gallons using the equivalence of 1 gallon equal to 128 fluid ounces.
Explanation:
Sanchez applied 6 fluid ounces of herbicide per acre on 300 acres of corn. To determine how many gallons he applied, we'll use the unit equivalence that 1 gallon = 128 fluid ounces. First, we'll calculate the total amount of herbicide in fluid ounces by multiplying the rate of application by the number of acres:
6 fluid ounces/acre imes 300 acres = 1800 fluid ounces total.
Next, we'll convert fluid ounces to gallons:
1800 fluid ounces imes (1 gallon / 128 fluid ounces) = 14.0625 gallons.
Therefore, Sanchez applied 14.0625 gallons of herbicide on the 300 acres of corn.
Suppose f(x) = x+1. Find the graph of f(1/4x)
The graph of the equation [tex]f(\dfrac{1}{4}x)=\dfrac{1}{4}x+1[/tex] has a slope of 1/4 and y-intercept of 1.
What is the graph of a linear equation.
The graph of a linear equation is a straight line graph. It can be expressed as function of x i.e. f(x) = y = mx + b.
Given that: f(x) = x + 1, we are to graph the function of f(1/4x). We will have to replace (1/4x) into the original equation.
[tex]f(\dfrac{1}{4}x)=\dfrac{1}{4}x+1[/tex]
It implies that the graph of f(1/4x) has a slope of 1/4 and the y-intercept is 1. So it will be less steeper than the equation f(x) = x + 1.
If you get a loan of $1,500 at an interest rate of 10% and the monthly payment is $131.85, what is the new principal after the first payment? (please explain how you got it)
Answer:
The new principal after the first payment is $ 1,380.65
Step-by-step explanation:
1. We calculate the amount of interest to pay in the first payment, this way:
Interest = Amount of loan * (interest rate/months in a year)
Replacing with the real values we know:
Interest = 1,500 * (0.1/12)
Interest = 1500 * 0.0083 = $ 12.50
2. Now we subtract the Interest from the monthly payment, as follows:
Payment to principal = 131.85 - 12.50
Payment to principal = $ 119.35
3. Finally we subtract that 1st payment to principal from the initial principal to get the new principal, this way:
New Principal = 1,500 - 119.35
New Principal = $ 1,380.65
The new principal after the first payment is $ 1,380.65

Answer:
Hours inequality (solution set): 0 ≤ x ≤ 7
Cost inequality: $2 ≤ y ≤ $100
Step-by-step explanation:
The babysitter charges $14 dollars per hour + bus fare
Price per hour = $14
Bus fare = $2
Mr. Tyler wants to spend no more than $100
Subtract the bus fare from the total amount, as that will not contribute to the babysitter's hours
$100 - $2 = $98
Divide by $14 per hour
$98 ÷ $14 = 7 hours
The maximum amount of time that Mr. Tyler could hire the babysitter for is 7 hours
This means that the hours cannot be greater than 7. It is given that x cannot be less than 0, because the babysitter cannot work negative hours.
0 ≤ x ≤ 7
This inequality shows that the Mr. Tyler will not have the babysitter work for less than 0 hours, or more than 7 hours. He will have to pay $2 minimum, or $100 max. Below is the inequality to represent this:
(y represents amount Mr. Tyler will pay)
$2 ≤ y ≤ $100

a book store cost $80 a day to keep open, and it spends $15 for each book that it sells. if each book sells for $23, what is the break-even point for this booksotre?
The break even point for this book store is 10
Solution:
Given that, book store cost $80 a day to keep open, and it spends $15 for each book that it sells
Cost to open the book store = $ 80
The formula for solving the break even point (BEP) is:
[tex]BEP = \frac{\text{Fixed cost}}{\text{Selling price - variable cost}}[/tex]
Fixed Cost is the cost that remains constant whether the services provided or products sold increases or decreases
Variable Cost is the cost that varies or differs in proportion to the products or services produced, whether they increased or decreased
In this problem,
Fixed cost = $ 80
Selling price = $ 23
Variable cost = $ 15
Therefore,
[tex]BEP = \frac{80}{23-15}\\\\BEP = \frac{80}{8}\\\\BEP = 10[/tex]
Thus break even point for this book store is 10
In order for the bookstore to continue its business, it should sell at least 10 books to meet its $80 cost

Ty sells signs in a monthly craft fair,and he can make 7 signs every 2 hours. Harrison can sign 15 signs every 4 hours. Who has the greater rate?
Answer:
If Ty can make 7 signs in 2 hours that means in 4 hours he could double that output to make 14 signs. Harrison, on the other hand, makes 15 signs every 4 hours. Therefore, by default - Harrison makes 1 more sign every 4 hours than Ty. Harrison has the greater rate. You have to figure out how many signs Ty can make in 4 hours, by multiplying 2 x 7 = 14. Hope that helps.

a relation contains the points (-5,-10) (-2,-4) (-1,-2) (4,8) (5,10) is this a function?
Answer:
This is a function and there is no value of x for which we will get two or more different values of y.
Step-by-step explanation:
A relation contains the points (-5,-10), (-2,-4), (-1,-2), (4,8), and (5,10).
So, if we want to model the equation that includes those points then we will get the equation of a straight line passing through the origin {Since the rate of change of y with respect to x is uniform.
The equation is y = 2x
Now, this is a function and there is no value of x for which we will get two or more different values of y. (Answer)

Which statement describes the graph of f(x) = x² - 6x + 9?
a line with an x-intercept of (-3, 0)
a parabola with an x-intercept of (-3, 0)
a line with an x-intercept of (3, 0)
a parabola with an x-intercept of (3, 0)
Answer:
A parabola with an x-intercept of (3, 0)
Step-by-step explanation:
We can immediately rule out the first and third options, because the equation of a second degree function is a parabola.
Your equation is
ƒ(x) = x² - 6x + 9 = 0
We can factor this equation as
ƒ(x) = (x - 3)²
The parent parabola, y = x², has its x-intercept at (0,0).
Your function subtracts three from x, so the intercept is shifted three units to the right.
The graph of your function is a parabola with an x-intercept of (3, 0).
The figure below shows the graph of your function shifted three units by subtracting three from x.

the arlington drama club is selling tickets to an upcoming play. They can sell at most 250 tickets. The adult tickets for $15 each and student tickets costs $5 each. They would like to raise at least $2000. It x represents the number of adult tickets and y represents the number of student tickets.
Number of adult tickets = 75
Number of student tickets = 175
Solution:
Let x represents the number of adult tickets and
y represents the number of student tickets.
Total number of tickets sold = 250
⇒ x + y = 250 – – – – (1)
Cost of adult ticket = $15
Cost of student ticket = $5
Total cost of collection = $2000
15x + 5y = 2000 – – – – (2)
Multiply equation (1) by 5
⇒ (1) × 5 5x + 5y = 1250 – – – – (3)
Subtract equation (3) from equation (2), we get
15x + 5y – 5x – 5y = 2000 – 1250
⇒ 10x = 750
⇒ x = 75
Substitute x = 75 in equation (1), we get
⇒ 75 + y = 250
⇒ y = 250 – 75
⇒ y = 175
Number of adult tickets = 75
Number of student tickets = 175
Test corner points for maximum revenue. The optimal solution is 250 adult tickets and 0 student tickets, yielding $3750.
To solve this problem, let's set up the equations based on the given information:
1. The total number of tickets sold cannot exceed 250:
[tex]\[ x + y \leq 250 \][/tex]
2. The total revenue must be at least $2000:
[tex]\[ 15x + 5y \geq 2000 \][/tex]
Now, let's solve this system of inequalities step by step:
Step 1: Graph the constraints:
Let's graph the lines corresponding to the equations:
x + y = 250 and 15x + 5y = 2000
Step 2: Find the feasible region:
The feasible region is the area that satisfies all the given constraints. In this case, it will be the region below or on the lines ( x + y = 250 ) and ( 15x + 5y = 2000 ), and within the boundaries of the axes.
Step 3: Identify the corner points:
The corner points of the feasible region are the points where the lines intersect or touch the boundary lines.
Step 4: Test the corner points:
Substitute the coordinates of each corner point into the objective function (the total revenue) to find which one yields the maximum revenue.
Let's start with the calculations:
1. **Graph the constraints:**
We'll need to find the intercepts of each line and draw them on the graph.
For ( x + y = 250 ):
When ( x = 0 ), ( y = 250 )
When ( y = 0 ), ( x = 250 )
For ( 15x + 5y = 2000 ):
When ( x = 0 ), ( y = 400 )
When ( y = 0 ),[tex]x = \frac{2000}{15} = \frac{400}{3} \)[/tex]
Now, let's plot these points and draw the lines.
2. **Find the feasible region:**
Shade the region below or on the lines ( x + y = 250 ) and ( 15x + 5y = 2000 ), and within the boundaries of the axes.
3. **Identify the corner points:**
The corner points of the feasible region are the points where the lines intersect or touch the boundary lines.
4. **Test the corner points:**
Substitute the coordinates of each corner point into the objective function ( R = 15x + 5y ) to find which one yields the maximum revenue.
Let's calculate the corner points:
Corner Point 1: (0, 0)
[ R = 15(0) + 5(0) = 0 ]
Corner Point 2: (250, 0)
[ R = 15(250) + 5(0) = 3750 ]
Corner Point 3: (0, 400)
[ R = 15(0) + 5(400) = 2000 ]
Now, let's compare the revenues:
- Corner Point 1: $0
- Corner Point 2: $3750
- Corner Point 3: $2000
The maximum revenue is $3750, which occurs at the corner point (250, 0).
Therefore, to maximize revenue while satisfying the given constraints, the Arlington Drama Club should sell 250 adult tickets and 0 student tickets.
