Answer:

$n=\frac{S}{180}+2$

Step-by-step explanation:

Hi there!

$S=(n-2)180$

We can isolate <em>n</em> by performing inverse operations on both sides to cancel out values.

First, divide both sides by 180 to isolate n-2:

$\frac{S}{180}=n-2$

Now, add 2 to both sides to isolate n:

$\frac{S}{180}+2=n\\n=\frac{S}{180}+2$

I hope this helps!

Determine whether the lines passing through the pairs of points are parallel, perpendicular or neither. Line a: (−4,4) and (8,−1

mario62 [17]

Answer:

Perpendicular.

Step-by-step explanation:

Find the slopes of each line through $m = \frac{(y_2-y_1)}{(x_2-x_1 )}$

Line a:

m = (-10-4) / (8--4)

= -14/12

= -7/6

Line b:

m = (20-8) / (18 -4)

= 12/14

= 6/7

When lines are parallel, they have the same slope. Since -7/2≠6/7, they are not parallel.

When lines are perpendicular, the product of the slopes equals -1.

-7/6 x 6/7 = -1

The product is -1, hence they are perpendicular lines.

How many 3 number combinations are possible if you can't repeat the numbers? The numbers range from 0-39

TEA [102]

Answer: 49600

Step-by-step explanation: There are 40 ways to choose the first number

and there are 40 ways to choose the second number.

Now we take some examples to determine how many choices there are for

the third number

If the second number is 23, then the 3rd number cannot be any of these

9 numbers 19,20,21,22,23,24,25,26,or 27, since they are not at least 5

numbers away from 23. Same for all other 40 second numbers.

Let's look at a second example which includes some on both sides of 0.

If second number is 2, we couldn't choose any of the 9 numbers 38,39,0,1,2,3,4,5,6.

So thats 40-9 or 31 choices for the 3rd number.

Answer 40*40*31 = 49600 ways.
