using the rule of 78 find the amount of unearned interest with finance charge 747 total payments 24 with remaining number of payments, when paid in full 8

Answers

Answer 1

If the loan is paid off in full after 8 remaining payments, the borrower is entitled to a refund of $218.87 of the finance charge.

The rule of 78:

The Rule of 78 is a method used by lenders to calculate how much of the finance charge on a loan should be refunded to the borrower if the loan is paid off early.

Formula to calculate the portion of the finance charge that has been earned by the lender so far. The formula is:

                     [ n / (n(n+1)/2) ] × I

Where n is the total number of payments in the loan and I is the finance charge.

Here we have

The finance charge = 747

Total payments = 24

First, Add up the number of payments made so far and the remaining number of payments to get the total number of payments in the loan:

=>  24 + 8 = 32.

Using the formula (n / (n(n+1)/2)) x I

[ 32 / (32(32+1)/2) ] x 747 = 0.707 x 747 = 528.13

This implies the lender has earned $528.13 of the finance charge so far.

Subtract the amount earned by the lender so far from the total finance charge to find the amount of unearned interest:

=> 747 - 528.13 = 218.87

Therefore,

If the loan is paid off in full after 8 remaining payments, the borrower is entitled to a refund of $218.87 of the finance charge.

Will replacing the car or the van save Paul's family more gas? How much money will it save them?

Answers

To calculate the number of gallons of gas a family will save over one year by replacing their old car with a new car, you will need to know the following information:

The current mileage of the old car: this will help you determine how many miles the car is driven in a year.

The miles per gallon (MPG) rating of the old car: this will tell you how many gallons of gas the car uses per mile.

The MPG rating of the new car: this will tell you how many gallons of gas the new car uses per mile.

The price of gasoline: this will allow you to determine the total cost of the gasoline used over the course of a year.

To calculate the number of gallons of gas saved, you will need to first determine the total number of miles driven in a year. Then, divide that number by the MPG rating of the old car to determine the number of gallons of gas used. Repeat the process using the MPG rating of the new car to determine the number of gallons of gas the new car would use over the same distance. Finally, subtract the number of gallons used by the new car from the number used by the old car to determine the total number of gallons of gas saved.

For example, if the old car gets 25 MPG and is driven 15,000 miles per year, it will use 600 gallons of gas (15,000 miles / 25 MPG = 600 gallons). If the new car gets 35 MPG, it will use 428.57 gallons of gas over the same distance (15,000 miles / 35 MPG = 428.57 gallons). The family would save 171.43 gallons of gas per year by replacing the old car with the new one (600 gallons - 428.57 gallons = 171.43 gallons).

Since the question was not complete, the answer is general. However, the solution is given with an example to make it simpler for you to solve.

The sum of square of two numbers is 85 the difference between the number is 1 find the numbers

Answers

Answer:

Let's assume that the two numbers are x and y, where x is greater than y.

From the given information, we can write two equations:

x^2 + y^2 = 85 (Equation 1)

x - y = 1 (Equation 2)

We can solve Equation 2 for x and substitute into Equation 1:

x = y + 1

(x = y + 1) into (Equation 1)

(y + 1)^2 + y^2 = 85

Simplifying this equation, we get:

2y^2 + 2y - 84 = 0

Dividing both sides by 2, we get:

y^2 + y - 42 = 0

Factoring this equation, we get:

(y + 7)(y - 6) = 0

Therefore, y = -7 or y = 6. Since x is greater than y, we can ignore the negative value.

So, y = 6 and x = y + 1 = 7.

Therefore, the two numbers are 6 and 7.

The equation of the ellipse graphed in the image is given as ((x-4)²/16) + ((y-6)²/4) = 1.

The standard form equation of an ellipse with center (h,k), horizontal axis of length 2a, and vertical axis of length 2b is,

((x-h)²/a²) + ((y-k)²/b²) = 1

Since the center is given as (4, 6), we have h = 4 and k = 6. The vertex is given as (0, 6) which means the horizontal distance from the center to the vertex is a = 4. Also, the co-vertex is given as (8, 6) which means the vertical distance from the center to the co-vertex is b = 2. Therefore, substituting these values in the equation of an ellipse, we get,

((x-4)²/4²) + ((y-6)²/2²) = 1

Simplifying, we get the equation of the ellipse,

((x-4)²/16) + ((y-6)²/4) = 1

Answers

Answer: 3200, less

Step-by-step explanation:

The rate at which the space explorers fly in miles per hour is the slope.

Space explorer B flies at a rate of 6400 miles per hour. This is because

y=mx+b, where m is the slope.

Space explorer A flies at a rate of (32000-16000)/(10-5) = 3200 miles per hour.   Slope is (y2 - y1) / (x2 - x1) where the coordinates are (x1,y1) and (x2,y2).

Space explorer B - Space Explorer A = 6400 - 3200 = 3200.

Therefore space explorer A travels 3200 miles per hour less than explorer B.

Answer:

Step-by-step explanation:

From the graph A find slope = (32000-16000)/(10/5)=3200

So for the equation y=3200x  plug 1 in you get 3200

For B if you plug in 1 you get 6400 miles per hour

Write your answer in this form: (x1,Y1),(×2,Y2).
If necessary, round to the nearest hundredth.
the orrect answer

Answers

y = a(x + 4)^2 + 12

where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use the y-intercept (0,-36):

-36 = a(0 + 4)^2 + 12

-36 = 16a + 12

-48 = 16a

a = -3

Therefore, the equation of the parabola is:

y = -3(x + 4)^2 + 12

To find the x-intercepts, we can set y = 0 and solve for x:

0 = -3(x + 4)^2 + 12

3(x + 4)^2 = 12

(x + 4)^2 = 4

x + 4 = ±2

x = -4 ± 2

So the x-intercepts are (-6,0) and (-2,0). Therefore, the answer is:

The percentage of values in the distribution between 28 and 30

Answers

Therefore, we can estimate that approximately 34.1% of values in this distribution fall between 28 and 30 and approximately 99.7% of values in this distribution fall between 24 and 36.

What is percent?

Percent is a unit of measurement that expresses a part-to-whole ratio as a fraction of 100. It is denoted by the symbol "%". Percentages are commonly used to express changes, proportions, and rates in many fields such as mathematics, science, economics, and finance. They are often used to compare values of different sizes and scales, and to convey information in a clear and concise way.

Here,

(a) To find the percentage of values in the distribution between 28 and 30, we need to determine the z-scores corresponding to these values and use the empirical rule to estimate the proportion of values that fall between these z-scores.

First, we calculate the z-score for a value of 28 as:

z = (28 - 30) / 2

= -1

Next, we calculate the z-score for a value of 30 as:

z = (30 - 30) / 2

= 0

According to the empirical rule for a normal distribution, approximately 34.1% of values fall between a z-score of -1 and 0. Therefore, we can estimate that approximately 34.1% of values in this distribution fall between 28 and 30.

(b) To find the percentage of values in the distribution falling between 24 and 36, we need to determine the z-scores corresponding to these values and use the empirical rule to estimate the proportion of values that fall between these z-scores.

First, we calculate the z-score for a value of 24 as:

z = (24 - 30) / 2

= -3

Next, we calculate the z-score for a value of 36 as:

z = (36 - 30) / 2

= 3

According to the empirical rule for a normal distribution, approximately 99.7% of values fall between a z-score of -3 and 3. Therefore, we can estimate that approximately 99.7% of values in this distribution fall between 24 and 36.

Since you cannot make a fraction of a round trip, you will need to make 5 round trips (back and forth) between Seattle and Miami to earn a free flight.

A rectangle has an area of 126 cm² and a perimeter of 50 cm.
What are its dimensions?
Its length is
Its width is
cm
cm, where length > width

Answers

Answer:

The rectangle is 7 cm x 18 cm

Step-by-step explanation:

w = width

l = length

(1)  A = wl = 126 cm²

(2) P = 2w + 2l = 50 cm

Solve equation (2) for w:

2w = 50 - 2l

w = (50 - 2l) / 2 = 25 - l         plug this in to equation (1)

(25 - l)(l) = 126

-l² + 25l - 126

Use quadratic formula to find the 2 roots of l:  a = -1, b = 25. c = -126

l = 7, 18

Since l > w, then l = 18

Solve for w:

w = 126/18 = 7

The numbers 4 and 40 has the highest common factor of 4 and lowest common factor of 40. second pair of numbers also has highest common factor of 4 and lowest common factor of 40.

What is the sum of the second pair of numbers?

Answers

The highest common factor (HCF) of 4 and 40 is 4, which means that 4 is the largest positive integer that divides both 4 and 40. The lowest common multiple (LCM) of 4 and 40 is 40, which means that 40 is the smallest positive integer that is a multiple of both 4 and 40.

Since the second pair of numbers also has an HCF of 4 and an LCM of 40, we can assume that those numbers are of the form 4a and 40b, where a and b are positive integers.

To find the values of a and b, we can use the fact that the HCF of 4a and 40b is 4. This means that a and b must have a HCF of 1, since 4 is not divisible by any number greater than 4. The only pair of positive integers that have a HCF of 1 and whose product is 10 (since 40/4 = 10) are 1 and 10. Therefore, a = 1 and b = 10.

So, the second pair of numbers is 4 x 1 = 4 and 40 x 10 = 400. The sum of these numbers is 4 + 400 = 404.

Therefore, the sum of the second pair of numbers is 404.
Final answer:

The second pair of numbers with a highest common factor (HCF) of 4 and lowest common multiple (LCM) of 40, other than 4 and 40, could be 8 and 20. Their sum is 28.

Explanation:

The highest common factor (HCF) of two numbers is the largest number that divides both numbers without leaving a remainder. It is also known as the greatest common divisor (GCD). On the other hand, the lowest common multiple (LCM) is the smallest common multiple of two numbers.

For the numbers 4 and 40, the HCF is indeed 4, and the LCM is 40. Let's denote our second pair of numbers as 'a' and 'b'. Given that these two numbers share the same HCF (4) and LCM (40), we could set up these equations:

HCF of 'a' and 'b' is 4, then 'a' and 'b' are multiples of 4.LCM of 'a' and 'b' is 40, then the product of 'a' and 'b' is equal to the product of their HCF and LCM, i.e., 'a' * 'b' = 4 * 40.

Given these constraints, the possible pairs ('a', 'b') could be (4, 40) or (8, 20). Since 4 and 40 have been provided as examples, we'll take the second pair. Therefore, the sum 'a' + 'b' = 8 + 20 = 28.

A bagel store orders cream cheese from three suppliers, Cheesy Cream Corp. (CCC), Super Smooth & Sons (SSS), and
Bagel's Best Friend Co. (BBF). One month, the total order of cheese came to 100 tons. (The store does do a booming
trade.) The costs were $80, $50 and $65 per ton from the three suppliers respectively, with the total cost amounting to
$5,900. Given that the store ordered the same amount from CCC and BBF, how many tons of cream cheese were ordered
from each supplier?
Cheesy Cream Corp.

tons

Answers

The number of tons of cream chees  ordered by each supplier are 20 tones

How to determine the number?

The given parameters are

x = tons of CCC **AND** BBF (can use same variable for both since these amounts [CCC & BBF] are the same)

y = t

2x+y = 100                         <== tonnage

80x + 65x + 50y = 5900       <== cost

  2x +     y = 100   <== multiply all by -50

145x + 50y =  5900

-100x - 50y = -5000

145x + 50y = 5900

------------------------

  45x  +   0   = 900

Making x the subject of the relation we have

x = 810/45 = 20 tones

if given f(x)= 2x^(2) +5 and g(x)= 1/2x
whats:
f+g
f-g
fg
f/g​

Answers

To find f+g, we need to add f(x) and g(x):

f(x) + g(x) = (2x^(2) +5) + (1/2x)

f+g = 2x^(2) + (1/2)x + 5

To find f-g, we need to subtract g(x) from f(x):

f(x) - g(x) = (2x^(2) +5) - (1/2x)

f-g = 2x^(2) - (1/2)x + 5

To find fg, we need to multiply f(x) and g(x):

f(x) * g(x) = (2x^(2) +5) * (1/2x)

fg = x + (5/2)x^(-1)

To find f/g, we need to divide f(x) by g(x):

f(x) / g(x) = (2x^(2) +5) / (1/2x)

f/g = 4x + 10x^(-1)
