In the summer of 1974, a Hungarian architect invented a three dimensional object that could rotate about all three axis. He wrote up the details of the cube and obtained a patent in 1975. The cube is now known worldwide as the Rubik's Cube. When you purchase the cube (3x3), it is arranged so that each face is showing a different colour, but after a few turns it seems next to impossible to return to the start. A manufacturer claims there are 8.85801027 x 10^22 possible arrangements, of which only contains only one correct solution. Do you agree with the claim? If yes, show how you obtain that answer; If no, what is the possible arrangements. Show your working properly.

we have a circle with the center ( x-center , y-center ) and the radius ( r-circle ).
so how can we find the end points on this circle ( x-end , y-end ).
for example x-center = 20 , y-center = 20 , r-circle = 10 , what is the x-end and y-end. ( ( x-center , y-center ) is the central point and ( x-end , y-end ) is on of the points on circumference )

I recently took advantage of a local nursery's sale featuring "you pay no sales taxes".

I bought rose bulbs at $11.55/bag, and violet bulbs at $13.65/bag, as well as some gardenia at $21.45, camellia at $30.03 and japanese maple at $50.05. The final bill came to $600.92.

How many gardenia did I buy?
