What is the perimeter of polygon ABCD?

Answers

Answer:

The perimeter is the sum of the length of the sides of a certain shape. In this case, the perimeter of the polygon would be the sum of the lengths of sides AB, BC, CD, and DA.

Step-by-step explanation:

Lets start computing the length of each side of the polygon. Using points A and B as a first example, we find that the distance between them will be:

d_(AB)=√((x_A - x_B) ^2+(y_A - y_B) ^2 )

Where (x_A , y_A ) and (x_B , y_B ) are the coordinates of points A and B respectively.

From the graph we can see that point A has coordinates (5, 12), B has coordinates (9, 9), C has coordinates (12, 5), and D has coordinates (0, 0). Puting values and computing the lengths we find that:

Lenght AB:

d_(AB)=√((x_A - x_B) ^2+(y_A - y_B) ^2)=√((5 - 9) ^2+(12 - 9) ^2)

d_(AB)=√((-4) ^2+(3) ^2 ) =√(16 + 9 )=√(25)

d_(AB)=5

Lenght BC:

d_(BC)= √((x_B - x_C) ^2 + (y_B - y_C) ^2 ) = √((9 - 12) ^2 + (9 - 5) ^2 )

d_(BC)=√((-3) ^2 + (4) ^2 )=√(9 + 16 ) =√(25)

d_(BC)=5

Lenght CD:

d_(CD)= √((x_C - x_D) ^2 + (y_C - y_D) ^2 ) = √((12 - 0) ^2 + (5 - 0) ^2 )

d_(CD)=√((12) ^2 + (5) ^2 ) = √(144 + 25 ) = √(169)

d_(CD)=13

Lenght DA:

d_(DA)= √((x_D - x_A) ^2 + (y_D - y_A) ^2 ) = √((0 - 5) ^2 + (0 - 12) ^2 )

d_(DA)=√((-4) ^2 + (-12) ^2 ) = √(25 + 144 ) = √(169)

d_(DA)=13

Therefor the result will be:

Perimeter = d_(AB) + d_(BC) +d_(CD) +d_(DA)= 5 + 5 + 13 + 13 = 36

Work the following pricing problems for services rendered. (Round to tenths.)Labor rate = $8.00 per hour
Labor time = 6 hours
Retail price of parts = $0
Total job cost = $86.00
Overhead rate?

Answers

Answer:

Overhead rate = $6.3

Step-by-step explanation:

Given : Labor rate = $8.00 per hour


Labor time = 6 hours


Retail price of parts = $0


Total job cost = $86.00

To find : Overhead rate

Solution:

Overhead cost =  Total Cost - The cost of all inputs

The Overhead Rate is this number divided by total labor hours.

Total job cost = $86.00

Labor Cost = labor rate × labor time = 8 × 6 = $48

Retail price of parts:$0

Overhead Costs = total cost - labor cost= $86 - $48 = $38

Now, we divided overhead cost by labor hours to get overhead rate,

Overhead Rate =(38)/(6)=6.33

Therefore, Overhead rate is $6.3

Answer:

55.8

Step-by-step explanation:

8x6= 48

48/86 into percent= 55.814%

therefore it would be rounded to 55.8

Guy decides to get in shape by running. The first day, he runs 1 mile in 12 minutes. Two months later he has decreased his mile time by 25%. What is his mile time now?

Answers

If you would like to know what is his mile time two months later, you can calculate this using the following steps:

25% of 12 minutes = 25% * 12 = 25/100 * 12 = 3 minutes

12 minutes - 3 minutes = 9 minutes

The correct answer would be 9 minutes.

Answer: 9 minutes.

Step-by-step explanation: 12-3=9.

3 x 4 = 12, 3 x 3 x 3=9, 3 x 3 x 3 x 3=12, 4+4+4=12. So if you think about it, three goes into twelve four times, just like a quarter goes into a dollar four times, or 25 goes into 100 four times. So, if you take twelve minus three and equal it, it is nine.

Given the roll of paper towels below how much plastic would be needed to cover the role so it can be sold given the diameter of the role is 10 inches and the height is 13 inches

Answers

Answer:

Amount of plastic need to cover paper role = 565.2 inches

Step-by-step explanation:

Given:

Diameter of paper role = 10 inch

Height of paper role = 13 inch

Find:

Amount of plastic need to cover paper role

Computation:

Radius of paper role = Diameter of paper role / 2

Radius of paper role = 10 / 2

Radius of paper role = 5 inch

Amount of plastic need to cover paper role = Total surface area of cylinder

Amount of plastic need to cover paper role = 2πr(h+r)

Amount of plastic need to cover paper role = 2(3.14)(5)(13+5)

Amount of plastic need to cover paper role = (3.14)(10)(18)

Amount of plastic need to cover paper role = 565.2 inches

Which of the following fractions is equivalent to 3/8?A.6/14
B.9/24
C.4/9
D.15/35

Answers

I'm going to suggest that we take these and "UN-simplify" them.

For each choice, divide the numerator by 3 and the denominator by 8.

Look at this:

A).  6/14

      6 ÷ 3 = 2  
    14 ÷ 8 = 1.875      ===>  2/1.875     not interesting


B).  skip B for just a second

C).  4/9

       4 ÷ 3 = 1.33
       9 ÷ 8 = 1.125        ===>  1.33/1.125    not interesting

D).  15/35

       15 ÷ 3 = 5
       35 ÷ 8 = 4.375    ===>   5/4.375         not interesting

But now look at choice-B:

B).  9/24

       9 ÷ 3 = 3
     24 ÷ 8 = 3        ===>  1/1    interesting !

-- To simplify  9/24, the top and bottom were divided by 3, giving 3/8.

-- To UN-simplify  3/8, the top and bottom were multiplied by 3, giving 9/24.

-- Choice-B  is the one that's equivalent to 3/8.
______________________________________________

OK.  All of that wasn't really necessary.
All you really need to do is take each choice and simplify it.

A).  6/14
       Divide top and bottom by 2  ===>  3/7

B).  9/24
       Divide top and bottom by 3  ===>  3/8 

C).  4/9
       Can't be simplified.  Already in simplest form.

D). 15/35
     Divide top and bottom by 5  ===>  3/7
