# Which equation can be used to find the perimeter of a regular octagon with sides of length 12 m? A. P = 8 + 12 B. P = 8(12) C. P = 12 ÷ 8 D. P = 2(8) + 2(12)

QUESTION POSTED AT 18/01/2020 - 07:14 AM

The basic definition of a perimeter is the boundary line of an object. For shapes and figures, this is basically the sum of the outermost sides that define the object. Since an octagon has eight sides, with each side measuring 12m, the perimeter can be obtained by multiplying 12 m by 8 sides, or in equation form:

P = 8(12)

Among the choices, this is letter B.

### Explain why the graphing calculator cannot be used to solve or approximate solutions to all polynomial equations.

Did your explanation include the following?

Some polynomial equations have complex solutions.

Therefore, complex solutions cannot be found by graphing the related system or function in the Cartesian (x-y) plane.

Polynomial functions with all complex solutions do not have x-intercepts, and the related system of equations will not intersect.

### In 4 years, harry’s age will be the same as jim’s age is now. in 2 years, jim will be twice as old as harry will be. find their ages now.

The answer to this question would be:
Jim     =6 years
Harry =2 years

To answer this question, you need to translate the description into a  mathematical equation. If H= Harry's ages and J= Jim's ages, then the equation should be look like this:

1. H+4= J
2. (J+2)= 2(H+2)
J+2= 2H+4
J= 2H +2

If you put the 1st and 2nd equation together, the result would be:
H+4= J
H+4= (2H +2)
H-2H= 2-4
-H= -2
H=2

After that insert the H value to either 1st or 2nd equation.
H+4= J
2+4=J
J= 6

The two fractions that we can extract from the given rates above are:
(1) 12 pages / 20 minutes
(2) 20 pages / 32 minutes
We can reduce the fractions or rates to their lowest term by dividing the numbers by 4 such that,
(1) 3 pages / 5 minutes
(2) 5 pages / 8 minutes
Therefore, the rates are not equivalent.

### Charles has 24 marble. he has 6 more yellow marbles than blue marbles. what is the equation

Required Equations are x + y = 24 & x - y = 6

Step-by-step explanation:

let x be the no of yellow marbles that Charles has.

and y be the no of blue marbles that Charles has.

Total Marbles that Charles has = 24

⇒ x + y = 24 ..............(1)

Charles has 6 more yellow marbles than blue marbles.

⇒ x = y + 6

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

Therefore, Required Equations are x + y = 24 & x - y = 6

### Ill give a tip please explain the steps Use this table as a reference for your interest rate percentages. Secured Unsecured Credit APR (%) APR (%) Excellent 4.80 5.25 Good 5.15 5.65 Average 5.85 6.20 Fair 7.00 7.65 Poor 8.20 9.15 8. You (or your parents) purchase a new car for $19,725.00 plus 4.75% sales tax. The down payment is$2,175.00 and you (or your parents) have an average credit rating. How much interest is accrued after the first month? (2 points) 9. You (or your parents) purchase a used car for $15,867.00 plus 5.25% sales tax. The down payment is 10% of the total cost and you (or your parents) have an excellent credit rating. What is your principal balance at the start of the loan? (2 points) 10. You (or your parents) are debating about whether to buy a new car for$19,072.00 or a used car for $15,635.00. Sales tax is 4.5%. You (or your parents) plan to make a down payment of$1,200.00 and your credit rating is fair. What is the difference in interest accrued by the end of the first month? (

Divide the APR by 360 days and multiply it by 30 days to get the monthly interest. Each loan is usually secured by the car you bought. So we will use the secured APR.

8. Average rating secured apr: 5.85% divide by 360 multiply by 30:  0.4875% monthly rate
Cost of car: 19,725 ; sales tax: 4.75% ; down payment: 2,175

19,725 x 1.0475 =  20,661.94 - 2,175 = 18,486.94 loan amount
18,486.94 x 0.4875% = 90.12 accrued interest for the 1st month.

9. Excellent rating secured apr: 4.80% divide by 360 multiply by 30: 0.40% monthly rate
Cost of car: 15,867 ; sales tax: 5.25% ; down payment: 10% of total cost

15,867 x 1.0525 =  16,700.02 x 90% = 15,030.02 the principal balance at the start of the loan.

10. Fair rating secured apr: 7% divide by 360 multiply by 30: 0.5833% monthly rate
Cost of new car: 19,072 ; sales tax: 4.5% ; down payment: 1,200
Cost of used car: 15,365; sales tax: 4.5% ; down payment: 1,200

19,072 x 1.045 = 19,930.24 - 1,200 = 18,730.24
18,730.24 x 0.5833% = 109.25 accrued interest

15,365 x 1.045 = 16,056.43 - 1,200 = 14,856.43
14,856.43 x 0.5833% = 86.66 accrued interest

109.25 - 86.66 = 22.59 is the difference in interest accrued by the end of the first month.
