Answer:

  C.  168°

Step-by-step explanation:

The exterior angle at any vertex of an n-gon will be ...

  360°/n

So a 30-gon will have exterior angles of ...

  360°/30 = 12°

The adjacent interior angle is supplementary to this, so is ...

  180° -12° = 168°

_____

<em>Using the reasonableness test</em>

You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.

Find the coordinates of point, P, which divides the line segment from A = (0, 4) to B = (6, 8) in a ratio of 2:1.
anastassius [24]
When a point divide a line segment A (x1,y1) B (x2,y2) into a ration of a:b, the coordinates of that point is x1+[a/(a+b)](x2-x1), y1+[a/(a+b)](y2-y1)
so x=0+(2/3)(6-0)=4
y=4+(2/3)(8-4)=6&2/3 (mixed number 6 and 2 over 3)
(4, 6&2/3) is the answer.

Nember 1: 2/7 as decimal
MariettaO [177]

Answer:

Number 1: <em>0.28571428571429</em>

Number 2: <em>2.1666666666667</em>

Number 3: <em>0.1875</em>

Number 4: <em>0.75</em>

Number 5: 0.5

Number 6: <em>13.875</em>

Number 7: <em>8.66666666667</em>

Number 8: <em>0.625</em>

Step-by-step explanation:

To get decimal

You have to divide numarator with denominator

2 : 7

5/10 = 5:10 = 0.5

When you have mixed number you have to multiply number not fraction with denominator and then add numarator

2 1/6 = 12 + 1 / 6 = 13/6 = 13 : 6 = 2.1666667

2x6 + 1

It doesn't matter how many numbers you'll add. At the end of the Number is best to add this

_

6

It means that number is repeating. You can still round it tho :-)

We can also say that

6

-- is same as 6:12

12

Solutions:

2/7 = 2:7 = 0.28571428571429

2 1/6 = 12 + 1 / 6 = 13/6 = 13 : 6 = 2.1666667

2x6 + 1

3/16 = 3 : 16 = 0.1875

3/ 4 = 3 : 4 = 0.75

5/10 = 5 : 10 = 0.5

13 7/8 = 104 + 7/8 = 111/8 = 111 : 8 = 13.875

13 x 8

8 10/15 = 120 + 10/15 = 130/15 = 130 : 15 = 8.66667

5/8 = 5:8 = 0.625

Maybe it can seems hard but it's pretty easy! I hope you will read whole explanation :-)

Have a nice day!
