Yes you are most likely correct Hectictar    

I am not sure if there is any specific meaning to those symbols.  I did not think of your interpretation  :)

Hi Mellie :)

I am really not convinced Hectictar,  

Your angles are correct but I do not think that there is enough info to give the arc lengths.

Your s relates to angles subtended from the centre.  The 360 is 360 degrees. It is not related to the length of the circumference.

 \(\text{You could say that } arc {PQ}= \dfrac{\pi r} {6}\\ \text{and } \qquad \qquad \qquad arc \;{QR}= \dfrac{2\pi r} {6}\\ \text{and } \qquad \qquad \qquad arc \;{RS}= \dfrac{4\pi r} {6}\\ \text{and } \qquad \qquad \qquad arc \; {SP}= \dfrac{5\pi r} {6}\\ \)

Where  r is the radius but I do not see how you can give exact values for these.  :/

(9x^2y^3) (12x^-3y^5) (2xy)

\((9x^2y^3) (12x^{-3}y^5)(2xy)\\ =9x^2y^3* 12x^{-3}y^5*2xy\\ =9*12*2\;x^2 x^{-3}x^1y^3y^5y^1\\ =216\;x^{2+-3+1}y^{3+5+1}\\ =216\;x^{0}y^{9}\\ =216\;y^{9}\\ \)

Ask this guy, he has his log all sorted. :)

Put more simply:

The calculator is correct  

Hi Bshirel,

When you get near 200 points you can prompt me again :)

5x+9+7x+3=180

5x+7x+9+3=180

12x+12=180

12x+12-12=180-12

12x=168

x= 168/12

x=14

Well Jane's question is more statistical because statistics is about making sense of data. (information) So, for example, if you asked lots ot people how many times they visited the park you could draw conclusions about how well used the park is. 

When is your birthday asinus ?

Let the numbers be a and b where b is bigger than a

a+b = 12    (1a)            b=12-a   (1b)

b+5a=32    (2)

Sub    b=12-a    into (2)

12-a +5a =  32

12 +4a     = 32

        4a    = 20

          a   =  5

b=12-a = 12-5  =7
