Answer 1

Answer:

Below in bold.

Step-by-step explanation:

The angle in a regular octagon =  180 - (360/8) = 135.

Using trigonometry  sin (135/2) = k/2 / EF

sin 67.5 = k / 2EF

2EF = k / sin 67.5

EF = k / 2 sin 67.5 = k/1.8478

Perimeter of octagon = 8 * k/1.8478

= 4.33k to the nearest hundredth.

What is the area of the base of this figure?

Answers

Answer:

12 cm²

Step-by-step explanation:

The base face of the trriangular prism is a triangle with base (of the triangle) 8 cm and height (of the triangle) 3 cm.

area of triangle = base × height / 2

area = (8 cm)(3 cm)/2

area = 12 cm²

It should be 12cm^2

Add them up and it’s 234 :]

Answer:

215.7176 ft^2

Step-by-step explanation:

One step at a time.

First, let's figure out what the square area is.

12 ft by 15 ft = A=wl=15·12=180 ft^2

Now we add the tringle area: K = 35.7176 ft2

Add: 215.7176 ft^2

Sides:

a = 12 ft

b = 7.93725 ft

c = 9 ft

Other:

P = 28.9373 ft

s = 14.4686 ft

K = 35.7176 ft2

Answers

Answer:

105 shifts

Step-by-step explanation:

Hourly net rate of pay = $12

1 shift = 8 hours

⇒ net pay per shift = $12 × 8 = $96

Total cost  = tuition + residence + books

                  = $4500 + $4800 + $700

                  = $10,000

To calculate how many shifts Joanne needs to work, divide the total cost by the pay per shift and round it up:

Number of shifts = total cost ÷ net pay per shift

                            = $10,000 ÷ $96

                            = 104.1666666...

                            = 105 shifts

Note: we need to round up, as if Joanne works 104 shifts, she will earn $9,984 which is not quite enough to pay for tuition, residence and books.

what is the next two term in the sequence 6, 10, 14, 16

Answers

Answer:

Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

The arithmetic sequence is 6, 10, 14 , 16

First term (a) = 6

Subtract the first term from the second term:

10 - 6 = 4

Subtract the second term form the third term:

14 - 10 = 4

Subtract the third term from the Fourth term:

16 - 14 = 4

Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.

So,

Next two terms are:

16 + 4 = 20

20 + 4 = 24

Hence,

Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

Given Sequence :- 6 , 10 , 14 , 16

To find :- Next 2 terms in the sequence

Solution :-

D( common difference ) = a2 - a1

D = 10 – 6

D = 4

Next two terms ,

16 + D ; 16 + 4 = 20

20 + D ; 20 + 4 = 24

The two angles form a straight line of 180 degrees.

This means they add to 180

115 + (4n-5) = 180

4n+110 = 180

4n = 180-110

4n = 70

n = 70/4

n = (35*2)/(2*2)

n = 35/2 is the answer as a fraction

n = 17.5 is the answer in decimal form
