    hmm... don't know this method, so dont really understand it. :D actually, hum logon nai addmaths main jis tarah sai kia hai, i was telling him to do it like that, i always did it like that, so it is much simpler for me (and to other addmaths students, i think) :)

    i used the same formula, completed part (a) in three lines, then forgot that we had to find n in terms of p, and then filled the whole page trying to find actual value of n. actually, i first found out n in terms of p, then replaced (2p+2) in 360/n! :D

    for these types of questions, they dont usually use one variable, two variables are always used.(remember mew and lamda?) anyway, if u have to solve for colinear, you usually have 2 variables. if not, you should add one yourself. :)

    you both have got the logic correct but are doing it wrong! for the first three co linear points B C and D, they have given the variable "k" . you cant assign the same variable to a different set of colinear points, ie F E and D. so you have to intriduce a new variable, eg "c" FD = c FE...

    just like square where we had to get all powers divisible by two, for cube we have to get all powers divisible by 3. so multiply it by 3*5*5 so it becoms 2^3 * 3^3 * 5^3(all powers divisible by three!)

    GAC is 90 degrees, ok? (tangent through centre) EAC is 180-128 = 52 ( Cyclic quadrilateral : opposite angles equal 180 degrees) GAE is GAC - EAC = 38 degrees.

    first convert both to either 10^7 form or 10^6 form so that they can be added or subtracted If u convert both to 10^7, then the amount of rice in brazil will become 0.76 * 10^7 (because you are multiplying by an extra 10, you have to divide the number beside it by 10 to keep the value same) the...

    area of shaded region = area of medium circle - area of smallest circle = 4*pie*x^2 - pie*x^2 = 3(pie)x^2 let perpendicular distance from A to DE be x cm. then perpendicular distance from A to CB is x+4 use proportionality for similar triangles so that 9 : 12 :: x : x+4 3x=36 x=12 x+4 = 16
