Answer:
The numerator is 57 ⇒ B
The denominator is 78 ⇒ B
The value of the fraction is 73.1% ⇒ A
Step-by-step explanation:
Let us solve it step by step
∵ The loan is 12 month
∵ The numerator is after 6 month
- Put n = 1 in each bracket
∴ The numerator = {(1 + 11) + (1 + 10) + (1 + 9) + (1 + 8) + (1 + 7) + (1 + 6)}
∴ The numerator = {12 + 11 + 10 + 9 + 8 + 7}
∴ The numerator = {57}
The numerator is 57
∵ The denominator = {(n) + (n + 1) + (n + 2) + .......... + (n + 11)}
- Do the same as the numerator put n = 1
∴ The denominator = {1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12}
∴ The denominator = {78}
The denominator is 78
Now find the value of the fraction
∵ The fraction = [tex]\frac{57}{78}[/tex]
∴ Its value = 0.730769230
- Multiply it by 100%
∴ Its value = 0.730769230 × 100% = 73.0769230%
- Round it to the nearest tenth
∴ Its value = 73.1%
The value of the fraction is 73.1%

–2(5n + 7) + 8n = 2(1 – 3n)
Answer:
n = 4
Step-by-step explanation:
Solve using the distributive property. This means you can multiply the number outside the brackets with each number inside the brackets. Then isolate "n" by moving all other numbers to the right side, leaving "n" alone on the left.
–2(5n + 7) + 8n = 2(1 – 3n) Distribute
(5n)(-2) + (7)(-2) + 8n = (1)(2) – (3n)(2) Multiply with each number in brackets
–10n + (–14) + 8n = 2 – 6n Remove brackets around –14
–10n – 14 + 8n = 2 – 6n Adding a negative is subtracting it's positive
–14 –2n = 2 – 6n
–14 + 14 –2n = 2 + 14 – 6n Add 14 to both sides
–2n = 16 – 6n
–2n + 6n = 16 – 6n + 6n Add 6n to both sides
4n = 16
4n/4 = 16/4 Divide both sides by 4
n = 4 Solved for "n"
Check answer by substituting "4" whenever there is "n" in the original equation. Then solve each side.
–2(5n + 7) + 8n = 2(1 – 3n)
–2(5(4) + 7) + 8(4) = 2(1 – 3(4)) Solve inside brackets
–2(20 + 7) + 32 = 2(1 – 12) Distribute
(20)(–2) + (7)(–2) + 32 = (1)(2) – (12) (2) Multiply where necessary
–40 + (–14) + 32 = 2 – 24 Simplify
–22 = –22 Same answer

The answer we found is correct.
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.

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.

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 bag contains blue marbles and red marbles, 58 in total. The number of blue marbles is 4 more than 5 times the number of red marbles. How many blue marbles are there?
Answer:
49 blue marbles
Step-by-step explanation:
From the question we are given;
Total number of marbles = 58 Blue marbles are 4 more than 5 times the red marblesWe need to determine the number of blue marbles;
Assuming the number of red marbles is x
Then, blue marbles will be 5x + 4
Therefore;
x + 5x + 4 = 58
6x + 4 = 58
6x = 54
x = 9
5x + 4 = 5(9) + 4 = 49
Therefore, the red marbles are 9 while the blue marbles are 49
Hence there are 49 blue marbles
Mateo has drawn a line to represent the parallel cross-section of the triangular prism. Is he correct? Explain.
Answer:
No
Step-by-step explanation:
A triangular prism has a uniform cross-section.A parallel cut of the solid will produce a cross section which is parallel to the triangular base.
A right prism contains uniform cross-sections, meaning the area of each cross-section is the same.
In this case, the position of the line indicating a cut will not produce polygons congruent to the base.

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.

–x and –8x
–2x and –7x
–3x and –6x
–4x and –5x
Answer:
The missing terms are - 3x and - 6x.
Step-by-step explanation:
The table represents the factorization of x2 – 9x + 18. It is partially completed.
So, the unknown term in the first row and second column will be the product of -3 and x i.e. -3x.
And the unknown term in the second row and first column will be the product of -6 and x i.e. -6x.
Therefore, the missing terms are - 3x and - 6x. (Answer)
The two terms that are missing in the diagram are –3x and –6x
How to determine the missing term Method 1The two missing term can be obtained as follow:
Multiply –3 and x together. The result is –3xMultiply –6 and x together. The result is –6xThus, the two missing term are –3x and –6x
Method 2The missing term can be obtained by doing a partial factorisation of the expression. This can be obtained as follow:
x² – 9x + 18
Multiply the 1st term (i.e x²) and the last term (i.e 18) together. The result is 18x².Find the two factors of 18x² such that the sum of the factors is equal to –9xThe factors are –3x and –6xSubstitute –3x and –6x in place of –9x in the equation above. We havex² – 9x + 18

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 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)

taxi B is given by c= 3d + 5. For what distance is
the cost of each taxi ride the same? How much would
this trip cost?
Answer:
(3 , 2.5)
the trip would cost $12.5
12.5 = 3.5 (3)+2
12.5 = 3 (2.5)+5
Step-by-step explanation:
The distance at which the cost of each taxi is the same is 6 miles.
The trip would cost $23.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
Taxi A:
c = 3.5d + 2
Taxi B:
c = 3d + 5
Where c is the cost of the taxi after d distance.
Now,
The cost of the taxi is the same.
3.5d + 2 = 3d + 5
3.5d - 3d = 5 - 2
0.5d = 3
d = 3/0.5
d = 30/5
d = 6
The cost of the taxi at d = 6.
c = 3.5d + 2 = 3.5 x 6 + 2 = 21 + 2 = 23
c = 3d + 5 = 3 x 6 + 5 = 18 + 5 = 23
Thus,
The cost of both taxis is the same after 5 miles.

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.

ABCD is a parallelogram. Segment AC = 4x + 10. Find the value of x and y.
Answer:
The values of x and y in the diagonals of the parallelogram are x=0 and y=5
Step-by-step explanation:
Given that ABCD is a parallelogram
And segment AC=4x+10
From the figure we have the diagonals AC=3x+y and BD=2x+y
By the property of parallelogram the diagonals are congruent
∴ we can equate the diagonals AC=BD
That is 3x+y=2x+y
3x+y-(2x+y)=2x+y-(2x+y)
3x+y-2x-y=2x+y-2x-y
x+0=0 ( by adding the like terms )
∴ x=0
Given that segment AC=4x+10
Substitute x=0 we have AC=4(0)+10
=0+10
=10
∴ AC=10
Now (3x+y)+(2x+y)=10
5x+2y=10
Substitute x=0, 5(0)+2y=10
2y=10

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.
