Hi mari379,

pemdas

pedmas 

they are the same because the d and the m are interchangable.

In Australia we teach BODMAS that is the same too

brackets, of (as in power of) the rest is obvious.

your welcome Melody!

That is very nicely answered Rosala, thank you.

mmm 

All 5 digit numbers  5! = 120

All 4 digit numbers begining with 4,5 of 6:    3*4*3*2 = 3*4! = 72

Total = 120+72 = 192

Hola anónimo,

10 mas 20 es 30 

i thought it was pemdas*? @ melody?

What Stu has said is correct.

$$\begin{array}{rll}
360^0&=&2\pi\\\\
180^0&=&\pi\\\\
1^0&=&\frac{\pi}{180}\\\\
150^0&=&\frac{150\pi}{180}\\\\
150^0&=&\frac{5\pi}{6}\\\\
150^0&\approx&2.618\;\;radians\\\\

\end{array}$$

no. i never heard that song lol

Quite right Anonymous, there are 3600 seconds in a degree, not 360; brain fade on my part I'm afraid!  I've corrected my original post.

I guess I should note that this is the same as using kinetic energy = force*distance, but now you must use total force along the line of motion, not just the frictional force (in the case of the object on the horizontal floor the frictional force was the total force along the line of motion).

inverse tan is the same as atan.

so it is just 2nd atan

There is plenty of google answers for this. 

1. Therefore, there are  2 pi radians in a full circle. We also know that there are 360 degrees in a circle. So, there are 360 degrees per  2 pi radians. Dividing 360 by 2 pi give us the value of about  57.2957 degrees per radian.
   
   Additionally, you can use a calculator online to calculate this. If you want to know how to calculate it there should be a different question. 
   
   A calculated answer to op's question gives 2.617993878 radian for 150 degrees. Which is 150 / value for radian. 
   
   I do not know what anonymous post was describing. This is information you can check online. Hope that helps.

I am sorry but your question does not make sense.

Angles are directly related to time (due to the earth rotating on its axis)

they each have 

60 seconds in a minute and

then time has 60 minutes in an hour and

angles have 60 minutes in a degree.

---------------

so 60 secs in a minute 

60 minutes in a degree

60*60=3600seconds in a minute

13.6 billion light years

I don't know - Is this a trick question.

Won't it take 13.6 light years to travel 13.6 light years?

 5π
 6  = 5· π
6 = 5· 30° = 150°

is it a truck!(just guessing if wrong)

Melody now is my answer correct!

your welcome DragonSlayer !actually i too didnt know it but Zegroes told me what that is as i had first heard this from him only!
