Pence is how much? Just .01? And what's the AE? 6 apples + 4 bananas = £1.00 Find: a) 1 of each b) 5 of each c) The cost of one banana d) The cost of one apple e) The rise in difference between apples and bananas. Answers: and you also said: "and the lenght of BC is given by the cube of the largest x-value in the following equation: " I thought you meant the maximum value( which are the solutions of the derivative) So I searched for the derivative instead of the roots. Correct solution (I hope :P) edit: I did some attempt, but it's probably wrong, as I asumed that the angle C = 90° then the surface of both is 969,376915 m². if C is not 90° then it would be impossible to define AB and so the surface, I think, or I'm seeing something over my head. I'll try to use words instead of symbols then. [edit] Better? Triangle ABC is not included in the circumference, lg was a writing mistake and is the same as log which is normal logarythms. Binarylog is binary logarythms and is only found once in the equation.  A field has the shape of a rectangle with a semi-circle at one end. The circumference of the field is 200m. At the other end, the field borders a triangularly shaped field congruent to the triangle ABC where angle A = 42,454 degrees and the lenght of BC is given by the cube of the largest x-value in the following equation: (sqr root (x^2 + 3^3)^2 * log 10^x - binarylog 4)/(10^2logx + sqr root (9x^2) - ((2^0,75)^4 + 2)) = 8 ^ 2/3 + y Where y is given by: log sqr root 10 * log (4y + 8)^2 = 1 AB = The short side of the rectangle = The diameter of the semi-circle Calculate the combined surface area of the two fields.  Win for you, Simon. :P More questions once i'm done with my homework. For Example: 55 (5 + 5) = 10 (1 + 0) = 1 Or: 28 (2 + 8) = 10 (1 + 0) = 1 Try it! :) Also there are more possibilities, but they would be unlikely, because there would be an age difference of 22 or 33 or 44, etc... Another solution(quite unlikely(22 year difference between sisters)): The sister would be 38 years old in 12 year. Now she's 26 years old. Megan is now 48 years old. (48 + 7) / 11 = 5, (26 + 7) / 11 = 3 The age of Megan can be defined by solving this equation: x = 22*n + 4 (where x is the age of Megan and n is an integer greater than 0) 7 years later, both of the ages are a multiple of 11, that means that the difference between the two ages is a multiple of 11. x - ((x + 4) / 2) = 11*n <=> x - (1 / 2)*x - 2 = 11*n <=> (1 / 2)*x = 11*n + 2 <=> x = 2*(11*n + 2) <=> x = 22*n + 4 The age of the sister after 12 years would be: x = ((22*n + 4) + 4) / 2 + 12 = 11*n + 4 + 12 = 11*n + 16 (where x is the age of the sister after 12 years and where n is an integer greater than 0) I will be in the smart section now. :p I forgot... :X Question time! :D 5 points: Megan's sister is half as old now as Megan will be 4 years from now. In 7 years, both ages will multiples of 11. How old is Megan's sister in 12 years? theyre called pyramid numbers ;D oh, also manufan, no point trying to get on that leaderboard...AK is barely active if ever, and ive been stuck 2nd for at least 2 months...in fact, its so old, it has my old username there... What is special about all the triangle numbers that are not the multiples of 3? An eleven year old pwned his maths teacher today with this (me), and if no-one gets it, then you're not good at lateral thinking. | GeneralFirst post of the topic Here we go! First question(1p) 6-2=?

I have an idea for topics like this, you could try to find people that want to help you maintain it, you quote a message of theirs and they can edit it, which will change the text in the first post.
