All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1080 degrees (from above)... And there are eight angles... So, the measure of the interior angle of a regular octagon is 135 degrees.

Answer:

2nd option

Step-by-step explanation:

You're goal is to isolate b by itself. The only part you need to worry about is the equation, the rest of the word problem is irrelevant.

The whole process of solving this is to do PEMDAS in reverse.

So first add/subtract all the values that does not have a <em>b</em> attach to it to the other side.

then multiply/divide all the values that is not a <em>b</em> to get the b-value by itself

What is the equation of the line containing the points (3, 1), (9, 3), and (27, 9)?
lutik1710 [3]

From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is

x= 3y

And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get

\frac{x}{3} = \frac{3y}{3}

\frac{x}{3}=y

or

y=\frac{x}{3}

Bus A and Bus B leave the bus depot at 9 am. Bus A takes 30 minutes to complete its route once and bus B takes 40 minutes to com
kirill [66]

Answer:

11 am

Step-by-step explanation:

Bus A and Bus B leave the bus depot at 9 am.

Bus A takes 30 minutes to complete its route once

Bus B takes 40 minutes to complete its route once.

We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route

30 = 3 × 10

40 = 4 × 10

= 3 × 4 × 10

= 120 minutes

120 minutes after 9 am is

60 minutes = 1 hour

60 minutes = 1 hour

= 2 hours.

9am + 2 hours

= 11 am.

Therefore, they be back at the bus depot together at 11 am
