In a canteen the ratio of pies to hot dog rolls is 2:1. The ratio of hot dogs to sausage rolls is also 2:1. There are 63 sausage rolls. How many pies are there?

answer: the answer is 23

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

yes   because as the functions are graphed they eventually will intersect unless otherwise
