Answer:

The selling price of the car is $152,220.

Step-by-step explanation:

To find the selling price of a car that is sold at a loss of 14% on the cost price, we can follow these steps:

Calculate the amount of the loss:

Loss = 14% of the cost price

Loss = 14/100 * $177,000

Subtract the loss from the cost price to find the selling price:

Selling Price = Cost Price - Loss

Selling Price = $177,000 - (14/100 * $177,000)

Simplify the expression:

Selling Price = $177,000 - ($24,780)

Selling Price = $152,220

Answer: To determine when the delayed watch will meet the accurate watch again, we need to find the number of hours it takes for the delayed watch to catch up by 9 minutes.

Since the delayed watch falls behind by 9 minutes per hour, it will catch up by 9 minutes after every hour. Therefore, it will take 1 hour for the delayed watch to catch up by 9 minutes.

Hence, the delayed watch will meet the accurate watch again after 1 hour.

Answer:

5 weeks

Step-by-step explanation:

the two linear equations are:

sibling (A)      and  sibling (B)

y = 10x + 25   and y = 5x + 50

where y = mx + c

and x represents the number of weeks

after how many weeks will their savings accounts have the same amount of money i.e. for which value of x will both equations have the same value

inserting the value of x in both equations:

for x = 2.5  A = 50 and B = 62.5

for x = 5     A = 75  and B = 75

for x = 15    A = 175 and B = 125

for x = 75   A = 775 and B = 425

thus, after 5 weeks both siblings A and B will have the same amount of money in their accounts

A specific X-value for the solution ,-4 is not equal to -3/2.

The x-value of the solution to the system of equations, we need to solve the given equation and the line represented by the data in the table. Let's begin by examining the first equation, 2x + 4y = 0.

We can rewrite this equation in terms of y:

4y = -2x

y = (-2/4)x

y = (-1/2)x

Now, let's use the data from the table to create a system of equations:

For the first data point (-1, 8):

y = (-1/2)x

8 = (-1/2)(-1)

8 = 1/2

Since 8 is not equal to 1/2, the first data point does not satisfy the equation.

For the second data point (3, -4):

y = (-1/2)x

-4 = (-1/2)(3)

-4 = -3/2

Again, -4 is not equal to -3/2, so the second data point does not satisfy the equation.

We can continue this process for the remaining data points, but from the information given, it seems that none of the data points satisfy the equation. Therefore, there is no solution to the system of equations.

The  length of boundary ABCD is 23.1

The length BC is the length of an arc subtended by angle 120 degrees at the center of a circle of radius 5.

The length of an arc, l, subtended by an angle, x degrees, in the center is given by l = 120 / 360 x pi x 2r

Thus, BC = 120 / 360 x 3.14 x 2 x 5 = 10.4667

Similarly, length DA is the length of an arc subtended by angle 30 degrees at the center of a circle of radius 5.

DA = 30/360 x 3.14 x 2 x 5 = 2.6167

Therefore, the approximate length of boundary ABCD

The perimeter of a rectangle with a length of Eight and one-sixth feet and a width of Six and two-thirds feet is  twenty-nine and four-sixths

The length of the rectangle is [tex]8\frac{1}{6}[/tex] feet, which can be written as a mixed number: 8 + 1/6 = 49/6 feet.

The width of the rectangle is [tex]6\frac{2}{3}[/tex]  feet, which can also be written as a mixed number: 6 + 2/3 = 6 2/3 = 20/3 feet.

To find the perimeter, we add twice the length and twice the width:

Perimeter = 2(length) + 2(width)

Perimeter = 2(49/6) + 2(20/3)

Perimeter = (98/6) + (40/3)

Perimeter = 98/6 + 80/6

Perimeter = 178/6

To simplify the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 2:

Perimeter = (178/6) ÷ 2

Perimeter = 89/3

So, the perimeter of the rectangle is 89/3 feet. To express it as a mixed number:

Perimeter =[tex]29\frac{2}{3}[/tex] feet

Answer:

(12 × 3) × 8 = 12 × (3 × 8)

Step-by-step explanation:

The associative property of multiplication states that the way in which factors are grouped in a multiplication expression does not change the product. In other words, if we have three or more numbers to multiply, it doesn't matter which order we multiply them in.

Out of the given number sentences, the example of the associative property of multiplication is:

(12 × 3) × 8 = 12 × (3 × 8)

This is because we can group the factors in either of the two ways and get the same product.

I) 1. The slope (m) of a line is 150.

2. The equation of the line is y = 150x.

II) 1. The slope (m) of a line is 100.

2. The equation of the line is y = 100x.

To estimate the line of best fit using the given points (1, 150) and (6, 900), we can follow these steps:

1. The slope (m) of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:

m = (900 - 150) / (6 - 1)

m = 750 / 5

m = 150

2. We can use the point-slope form of a linear equation to write the equation of the line:

y - y₁ = m(x - x₁)

So, y - 150 = 150(x - 1)

y - 150 = 150x - 150

y = 150x

So, the equation of the line is y = 150x.

3. The slope of the line represents the change in y (sales) for each unit increase in x (TV ads). In this case, the slope is 150, which means that for every TV ad, CD sales increase by about 150 units.

Similarly, using the points (1, 100) and (8, 800) to estimate the line of best fit:

II) 1. the slope of the line:

m = (800 - 100) / (8 - 1)

m = 700 / 7

m = 100

and, the equation of the line:

y - 100 = 100(x - 1)

y - 100 = 100x - 100

y = 100x

So, the equation of the line is y = 100x.

and, the slope of the line represents the change in y (sales) for each unit increase in x (magazine ads). In this case, the slope is 100, which means that for every magazine ad, CD sales increase by about 100 units.

Answer:

Therefore, Marge's finance charge on the computer is $97.

Step-by-step explanation:

To calculate Marge's finance charge on the computer, we need to find the total amount she will pay for the computer through the installment plan and subtract the original purchase price.

Down payment = $100

Total amount paid for the computer = Down payment + Monthly payment * Number of months

Total amount paid = $100 + ($58 * 12)

Total amount paid = $100 + $696

Total amount paid = $796

Finance charge = Total amount paid - Purchase price

Finance charge = $796 - $699

Finance charge = $97

Therefore, Marge's finance charge on the computer is $97.

The volume of the larger cylinder is 201 cm³.

Given that,

Ratio of the heights of two cylinders = 1 : 3

We have to find the volume of the larger cylinder.

The formula to find the volume of a cylinder is,

Volume of cylinder = π r² h, where r is the radius and h is the height of the cylinder.

Let height of smaller cylinder = h

Height of larger cylinder = 3h

π r² (h) = 67

Volume of larger cylinder = π r² (3h)

                                          = 3 [π r² (h)]

                                          = 3 × 67

To find the volume of the empty space in the box, we need to subtract the volume of the basketball from the volume of the box.

Volume of the basketball = (4/3) * π * r^3

= (4/3) * 3.14 * (4.75 in)^3

Volume of the box = side length^3

= (9.5 in)^3

Empty space volume = Volume of the box - Volume of the basketball

Empty space volume = (9.5 in)^3 - (4/3) * 3.14 * (4.75 in)^3

Calculating this equation will give us the volume of the empty space in cubic inches. Rounding the answer to the nearest cubic inch will provide the amount of packing foam needed to fill the empty space.

The monthly loan payment for a $60,000 loan with a $4,000 down payment, 13% interest rate, and a term of 60 months is approximately $1,289.49.

To calculate the monthly loan payment, we need to use the loan amount, down payment, interest rate, and term.

Loan amount: $60,000

Down payment: $4,000

Principal amount: Loan amount - Down payment = $60,000 - $4,000 = $56,000

Interest rate: 13% per annum (or 0.13 as a decimal)

Monthly interest rate: 13% / 12 = 0.0133 (approx.)

Term: 60 months (5 years)

Now, let's calculate the monthly loan payment using the formula for a fixed-rate loan:

Monthly payment = P * (r * (1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal amount

r = Monthly interest rate

n = Total number of payments

Substituting the values into the formula:

Monthly payment = $56,000 * (0.0133 * (1 + 0.0133)^60) / ((1 + 0.0133)^60 - 1)

Using a calculator, the approximate monthly loan payment comes out to be $1,289.49.

Therefore, the monthly loan payment for a $60,000 loan with a $4,000 down payment, 13% interest rate, and a term of 60 months is approximately $1,289.49.
