Total selling price $1,238.45; sales tax rate 8 1/2%. what is the sales tax?

Step-by-step explanation:

The formula to calculate the future value of a present value deposit with compounding interest is:

FV = PV × (1 + r/n)^(n*t)

Where:

PV = Present Value (the initial deposit)

r = Annual interest rate (as a decimal)

n = Number of compounding periods per year

t = Number of years

Using this formula, we can calculate the future value of the $6000 deposit after 15 years:

PV = $6000

r = 6% = 0.06

n = 4 (compounded quarterly, i.e. 4 times per year)

t = 15 years

FV = $6000 × (1 + 0.06/4)^(4*15)

FV = $6000 × 1.458^60

FV = $6000 × 6.2565

FV = $37,539.00

Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.

Answer:

a. To the nearest whole inch:

To find the length of one side of the square frame, we need to take the square root of the area. So:

√(55) ≈ 7.4

Rounding 7.4 to the nearest whole inch, we get 7 inches. Therefore, the length of one side of the frame is 7 inches.

b. To the nearest tenth of an inch:

Again, we take the square root of the area:

√(55) ≈ 7.4161984

Rounding 7.4161984 to the nearest tenth of an inch, we get 7.4 inches. Therefore, the length of one side of the frame is 7.4 inches.

Step-by-step explanation:

Therefore , the solution of the given problem of  equation comes out to be (x, y) = (2, 5).

The foundation of a model of linear regression is the equation y=mx+b. The inclination is B, and the y-intercept is m. Although it is true that y and y are separate parts, the the above sentence is frequently referred to as a "mathematics problem with two variables". Only two factors are present in bivariate linear equations. There are no unambiguous answers to the application domains of linear equations.

Here,

=> 5y + 2x = 2 ...(1)

=> x = -2y + 3 ...(2) (2)

Equation (1) is completed by substituting the value of x from equation (2):

=> 5y + 2(-2y + 3) = 2

When we simplify the previous solution, we get:

=>y = 4/3

Adding the value of x to equation (2) now yields:

=> x = -2(4/3) + 3

When we simplify the previous solution, we get:

=> x = 2/3

As a result, the answer is (x, y) = (2/3, 4/3.

=> y + 2x = 9 ...(3)

=> y - 3x = -1 ...(4)

Equation (3) by 3 and Equation (4) by 2 are multiplied to yield:

=>3y + 6x = 27 ...(5)

=> 2y - 6x = -2 ...(6)

Equations (5) and (6) combined give us:

=>5y = 25

Consequently, x = 5.

Adding the number of y to equation (3) yields the following results:

=> 5 + 2x = 9

When we simplify the previous solution, we get:

=> x = 2

Consequently, the answer is (x, y) = (2, 5).

Answer:

Step-by-step explanation:

Answer:

the vertex form of the quadratic equation y=3x^2 + 12x + 14 is y = 3(x + 2)^2 - 2. The vertex of this parabola is located at the point (-2, -2).

Step-by-step explanation:

To rewrite the quadratic equation y=3x^2 + 12x + 14 into vertex form, we need to complete the square.

First, we can factor out the coefficient of x^2, which is 3:

y = 3(x^2 + 4x) + 14

Next, we need to add and subtract a constant term inside the parentheses that will allow us to complete the square. We can do this by adding and subtracting (4/2)^2 = 4:

y = 3(x^2 + 4x + 4 - 4) + 14

Now we can write the first three terms inside the parentheses as a squared expression:

y = 3((x + 2)^2 - 4) + 14

Finally, we can simplify this equation by distributing the 3 and combining like terms:

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

So the vertex form of the quadratic equation y=3x^2 + 12x + 14 is y = 3(x + 2)^2 - 2. The vertex of this parabola is located at the point (-2, -2).

Answer:

Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

Step-by-step explanation:

To calculate the break-even point, we need to find the total contribution margin, which is the difference between the total sales revenue and total variable expenses.

For Product R38T, the contribution margin is $33,000 - $8,840 = $24,160.

For Product X08S, the contribution margin is $54,000 - $32,050 = $21,950.

The total contribution margin for both products is $24,160 + $21,950 = $46,110.

To calculate the break-even point, we divide the total fixed expenses by the total contribution margin:

Break-even point = Total fixed expenses / Total contribution margin

= $36,130 / $46,110

= 0.784

Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

Yes triangles are similar.

SAS theorem is used to prove triangles are similar.

The SAS similarity theorem states that if any two sides of the first triangle are exactly proportional to any two sides of the second triangle and the angle created by these two individual triangles is identical, then the two triangles must be similar. When we only know the length of two sides and the angle produced between those two sides in each triangle, this rule is often implemented.

ΔRST and ΔHJK triangles are similar.

According to the SAS theory,

∠ S=∠J (angles are equal)

The two tangent with common external point theorem indicates that the relationships between the lengths of the segments are;

5·x - 8 = 8·x - 35

8·x - 35 = 5·x - 8

8·x - 5·x = 35 - 8 = 27

Answer:

The following items would be decreased by the mortgage payment:

Notes payable (or long-term debt)

Interest expense

Cash (or checking account, or bank account)

Step-by-step explanation:

The mortgage payment has two components: a principal payment and an interest payment. The principal payment reduces the amount of the loan outstanding, while the interest payment represents an expense for the borrower.

Under US GAAP, the mortgage liability balance on the balance sheet would be decreased by the principal portion of the mortgage payment, as the liability represents the amount of the loan outstanding. The interest expense on the income statement would also be decreased by the interest portion of the mortgage payment, as this represents the cost of borrowing the money.

Therefore, the items that would be decreased by the mortgage payment are:

Mortgage liability on the balance sheet (by the principal portion of the payment)

Interest expense on the income statement (by the interest portion of the payment)

The amount of money you pay for your mortgage, which is $36,721, would become smaller for these things:

Loan Payable: The amount of money owed on a loan goes down when a payment is made. So, the amount of money owed for the loan would go down by $36,721.

Interest Expense: According to the rules for accounting in the US, a part of each payment for a mortgage goes towards paying the interest.

Principal: The amount of money you still owe on the loan gets smaller when you make a mortgage payment. So, the amount of money the Principal decreases by is $36,721.

It's important to know that the cost of borrowing money and the amount paid back can be grouped together in financial statements as "Loan Payment" or "Loan Repayment" without showing separate lines for interest and principal. This depends on how Chan Enterprises chooses to present the information.

Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².

Surface area is the measure of the total area that the surface of a three-dimensional object occupies.

To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:

Surface area = 2(lw + lh + wh)

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

So, if we have a rectangular prism with the following dimensions:

Length (l) = 3.5 inches

Width (w) = 4 inches

Height (h) = 6 inches

The surface area can be calculated as follows:

Surface area = 2(lw + lh + wh)

= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)

= 2(14 + 21 + 24)

= 2(59)

Answer:

the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

Step-by-step explanation:

To find the missing 10%, you can use the fact that 100% is equal to the whole amount, and set up a proportion:

90/100 = 144/x

Simplifying this proportion, you can cross-multiply:

90x = 100 * 144

Then, you can solve for x:

x = (100 * 144) / 90

x = 160

Therefore, the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.

The radius of the circle is r = 3.75

The radius of a circle is the distance from its center to its circumference.

To find the radius of the circle, we see that there is a right-angle triangle there. So, using Pythagoras' theorem, we have that

AC² = AB² + BC²

(6 + r)² = 9² + r²

Expanding the brackets, we have that

36 + 12r + r² = 81 + r²

Cancelling out r², we have that

36 + 12r = 81

Subtracting 36 from both sides, we have that

12r = 81 - 36

y represent the total spend on seeing movies.  Seth's dad pays a one time 40 fee and then 1 for each movie.  The x represents the number of movies that he goes to see.

Examples:

His total cost if he goes to see one movie is

y = x + 40

y = 1 + 40

y = 41

His total cost if he goes to see 10 movies is

y = x + 40

y = 10+ 40

y = 50

His total cost if he goes to see 15 movies is

y = x + 40

y = 15 + 40

y = 55
