^ lol that was ages ago..its started already its going to be the second week tomorrow
 At a party 28 handshakes were exchanged. Each Preson Shook hands exactly once with each of the others. How many people were at the party? Is there an easier way other than drawing eveything out? i know the answer is 8 but i think there would be an easier way to do it 

LOVE, LOVE, LOVE, LOVE I'm in love


^ 8 people, and yes there is.
Though not at the level of maths you are doing. This is a combinations problem. You combine 8 people (r) in a way such that each combination takes up 2 people (n). This is written as a matrix, like this (8 2) but with the 8 above and the 2 below, within the brackets. The formula for this requires the reciprocal function. (!) which is n*(n1)*(n2)*...*(nn) = n! I shan't state it here as solving these is horrible, but just so you know there is some maths behind my answer. 

N/A


^ even though i don't understand..i thank you


LOVE, LOVE, LOVE, LOVE I'm in love


Does anyone know a good website to help with Advanced Algebra and Trig????


I can't believe I'm in love like a mom?


which subjects do you have in mind? i can probably find some for you. and i don't live in scotland, but is england good enough for you? XD 



7 + [2 + (2)]= 7 + 0
<Would the above be an example of the distributive property? If not, which property would it be? I completely forgot about properties on my Algebra 2 review worksheet x_x

^Oh, maybe I should have clarified. The directions are to identify the property shown.
Its either distributive, identity, associative, or communitive. 



hahahah i start i 2 weeks:P, but wen i need ur ppls help illl b sure 2 post

They employ 40 young people to hand them out and pay them £1.25 for every 50 leaflets they issue. Each person is given the same number of leaflets. How much does each one earn, and what is the total cost to the firm? (you get 5 marks for this) ok, here's what i think. basically there's only one unknown (what grade are you in?) 30 000 leaflets 40 employees 1.25 every 50 leaflets therefore: 30 000 / 40 = 750 leaflets each employee 750 leaflets / 50 = 15 15 x 1.25 = 18.75 (euros) each employee total: 18.75 x 40 employees = 750.00 (euros) 

lurking...


^ erm we don't use euros we use english money..is that still the same?


LOVE, LOVE, LOVE, LOVE I'm in love


^ thankyou to both..actually that isn't hard at all, i didn't try the question myself :X
cheat *coughs* xD erm here we don't work it that way..we don't say grades so i don't know what you call it..I'm 13 anyway :D A firm has 30000 leaflets to hand out.
