Percent of the total amount a per the given list price, documentation fee , registration fee and other payment paid by Charles is given by :
Option c. 16.70%
Cost of his old 2004 Dodge Neon = $6591
Sales tax = 6.88%
Dealer gives 80% trade in price on hos car
After tax selling price of the car
= 6,591 × (80/100) × [ 1 - (6.88/100) ]
= $4910.03
= $4,910
Vehicle registration amount = $1,089
List price of car = $21,450
Documentation fee = $124
Total cost of the car
= $21,450 + $1,089 + $124
= $22,663
Net amount Charles needs to pay
= $22,663 - $4,910
= $17,753
Monthly payment at the rate of 12.28% compounded monthly for 3 years
= 17753 [ 12.28%( 1+ 12.28%)^3 / [( 1+ 12.28%)^3 -1 ]
= $592
Total amount paid by Charles
= $592 × 36
= $21,312
Total interest paid by Charles
= $21,312 - $17,753
= $3,559
Percent of the total amount
= ( $3,559 / $21,312 ) × 100
= 16.699%
= 16.70%
Therefore, the percent of the total amount paid by Charles is equal to Option c. 16.70%.

Choose the correct answer below.
OA (x+1)(x-8)=56
OB. x(x +9)(4)=56
OC. (x+1)(x-8)(4)=56
OD. x(x +9)=56
OC (x+1)(x-8)(4)=56 indicates that the volume of the box is 56 in³ because it takes into account the length of the sides after the four corners were cut off, and the height of the box which is 4 in. The equation can be written as (length of sides)(width of sides)(height) = volume.
What is a volume?A volume is a three-dimensional space that contains a specific amount of material, which is commonly measured in liters, cubic meters, or gallons. It is frequently used to calculate the capacity of containers like tanks, bottles, and barrels. Volume may also refer to the quantity of space occupied by an item, such as the volume of a room or the volume of a sphere.
In the given question, OC is the correct answer: (x+1)(x-8)(4)=56.

Rocky has 7 bottles of water. he will buy more bottles of water from the store. the store has 8 cases in stock and each case contains 24 bottles of water. the store will not sell partial cases. the function that models the number of bottles of water rocky will have after his purchase is , where c is the number of cases of water he buys. what is the practical domain of the function?
Answer:
{1, 2, 3, 4, 5, 6, 7, 8}
Step-by-step explanation:
In this problem, we use the variable c to represent the independent quantity. This means that the domain is all possible values for c. Since the store only has 8 cases of water, the domain cannot be any number larger than 8. Since the store only sells complete cases, not partial cases, of water, the domain cannot be a fraction or decimal number. This means that the practical domain, or domain that makes sense for the problem situation, is {1, 2, 3, 4, 5, 6, 7, 8}.

Which the correct solution of the equation 1/2a + 2/3b = 50, when b=30
According to the given formula, the value of a is:
60
If b=30 then 1/2a+2/3b=50
How do you find the value of a in the given equation?First, replace the 30 in b.
1/2a+2/3(30)=50
According to the order of operations, we must first multiply 2/3 by 30. yes:
2/3 times 30 is equal to 20.
2/3 times 30/1. 3 is 10 times 30, so 2 times 10 = 20. Now it looks like this:
1/2a+20=50
20 and 50 are similar terms, so I'll put those two together. Move the positive 20 to the other side where the 50 is. 20 has moved to the other side, so it changes sign and becomes negative.
yes:
1/2a=50-20
50-20 = 30
1/2a=30
Multiply each side by 2, because only 2 makes the variable 1a.
1/2a × 2 = 1a
30 times 2 = 60, so:
1a=60, which is also a=60. So a perfect simplification is a= 60

Henry and Jessica skipping rocks across the surface of a pond for every nine rocks at Henry throws he got five of them to skip across the pond for every twelve rocks
Jessica throws she got seven of them to skip across the pond who gets more rocks to skip across the surface of the pond
Jessica gets more rocks to skip across the surface of the pond than Henry.
To determine who gets more rocks to skip across the surface of the pond, we will take the ratio of rocks that skip to rocks that are thrown for each person.
For Henry, the ratio is 5 rocks that skip to 9 rocks thrown i.e 5/9.
For Jessica, the ratio is 7 rocks that skip to 12 rocks thrown i.e 7/12.
Now to compare the ratios, we need to convert them into like fractions. We will do this by making the denominations of both the fractions same.
We will multiply the numerator and denominator of Henry's ratio by 12 to get -
5/9 x 12/12 = 60/108
Also, we will multiply the numerator and denominator of Jessica's ratio by 9 to get -
7/12 x 9/9 = 63/108
Comparing the numerators we get 60<63.
This implies that 60/108 < 63/108.
Therefore, Jessica gets more rocks to skip across the surface of the pond.

Answer:
w = 11 , x = 25
Step-by-step explanation:
for Δ ABC ≅ Δ TUV, then corresponding sides must be congruent, that is
AB = TU and BC = UV ( using these to create 2 equations )
- 9x + 20w + 89 = 4w + x + 15 ( subtract 4w + x + 15 from both sides )
- 10x + 16w + 74 = 0 → (1)
and
x + w + 41 = - 18w + 11x ( subtract - 18w + 11x from both sides )
- 10x + 19w + 41 = 0 → (2)
multiplying (2) by - 1 and adding to (1) will eliminate x
10x - 19w - 41 = 0 → (3)
add (1) and (3) term by term to eliminate x
0 - 3w + 33 = 0 ( subtract 33 from both sides )
- 3w = - 33 ( divide both sides by - 3 )
w = 11
substitute w = 11 into either of the 2 equations and solve for x
substituting into (1)
- 10x + 16(11) + 74 = 0
- 10x + 176 + 74 = 0
- 10x + 250 = 0 ( subtract 250 from both sides )
- 10x = - 250 ( divide both sides by - 10 )
x = 25
thus the values x = 25 and w = 11 will make the triangles congruent
Roberto and Maeko open a pet store and start with 5 hamsters for sale. Hamster populations usually triple every cycle. One cycle is equal to 4 months. Write an equation in function notation to represent the change in the number of hamsters as a function of the cycle number, c. Explain how you determined your equation.
The number of hamsters as a function of the cycle number, c, can be represented by the equation:
f(c) = 5 * 3^c
This equation was determined by the fact that the population triples every cycle and the starting number of hamsters is 5. The function notation is f(c) which represents the number of hamsters as a function of the cycle number. The base of the equation is 3, which represents the rate at which the population triples. The exponent is c, which represents the cycle number. The coefficient is 5, which represents the starting number of hamsters.
how does the graph of f(x)=2^x+2 compare to the graph of g(x)=2^x +2
Answer: The graph of f(x) = 2^x and g(x) = 2^x +2 are the same.
Explanation: The functions f(x) = 2^x and g(x) = 2^x + 2 are identical. The only difference between them is the constant term in the second function. This constant term does not change the shape, direction or the relative position of the graph of the function, it only shifts the graph along the y-axis. Because both functions have the same base, the graphs will have the same shape, direction and relative position, regardless of the constant term.

Find the 9th term of the arithmetic sequence -5x + 2,
-11x - 3,-17x -8,...
Answer: An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. We can call this constant difference "d".
In this sequence, we can see that the difference between consecutive terms is -6x - 5.
The 9th term of an arithmetic sequence can be found by using the formula:
a_n = a_1 + (n-1)d
Where a_n is the nth term of the sequence, a_1 is the first term of the sequence and d is the common difference.
Given the sequence -5x + 2, -11x - 3, -17x -8, ...
The 9th term is:
-5x + 2 + (9-1) (-6x-5) = -5x + 2 - 48x - 40 = -53x -38
Therefore the 9th term of the arithmetic sequence is -53x -38.

$1,496. 70
$1,682. 94
$870. 83
The monthly payment during the initial period is about $1,682.94
The type of loan Jackie obtains is an Adjustable Rate Mortgage, ARM, loan, which is a 4/2 ARM
The introductory interest rate of 5% is fixed for the first 4 years, and will be adjusted every 2 years after the first four years.
Let us assume that m represents the initial monthly payment.
[tex]M=\frac{P.(\frac{r}{12} ).(1+\frac{r}{12} )^n}{(1+\frac{r}{12} )^n - 1}[/tex]
where, M is the monthly payment during the initial period
P is the amount on loan
r is the interest rate = 5% = 0.05
n is period = 30 × 12 = 360
Here, P = $313,500
r = 5%
r = 0.05
n = 30 × 12
n = 360
Substituting these values in the above formula we get,
[tex]M=\frac{313500\times (\frac{0.05}{12} ).(1+\frac{0.05}{12} )^{360}}{(1+\frac{0.05}{12} )^{360} - 1}[/tex]
