Best ResponseYou've already chosen the best response.04/8 = a/b for the first eqn yes?

Best ResponseYou've already chosen the best response.0well , we can find the distance between (12,0) and (3,9) , and that distance should be equal to a+b

Best ResponseYou've already chosen the best response.0distance between the points = sqrt [ ( 123)^2 + (09)^2 ] = sqrt [ 9^2 + 9^2] = sqrt( 2 x 9^2) = 9sqrt(2)

Best ResponseYou've already chosen the best response.0so a/b = (1/2) > ie b =2a , and a+b = 9sqrt(2) 2 eqns, two unknowns, pretty easy to solve yes?

Best ResponseYou've already chosen the best response.0it doesnt help if u dont say what it is you are confused about. nevertheless , this questionn is pretty similar to the other ones you put up ( though it is a bit harder ). The first eqn came from ratios of intersections of parallel lines

Best ResponseYou've already chosen the best response.0then we needed to find another eqn to relate a and b , because you need two eqns to solve two unknowns , and we obverse from the picture that a+b was a distance between two points

Best ResponseYou've already chosen the best response.0(h/H)2 = 9/25; Volume of large prism/Volume of small prism= (h/H)3

Best ResponseYou've already chosen the best response.0:S, dont really undertand what u want

Best ResponseYou've already chosen the best response.0my bad n it not that one up there a + b = sq root of (123)2 + (09)2. Once you have solved for a + b, then 4/12 = a/a+b .

Best ResponseYou've already chosen the best response.0I guess that would have been another way to get the second eqn

Best ResponseYou've already chosen the best response.0what? the answers to the question are a=3sqrt(2) b= 6sqrt(2)
