In a study of over 15,000 teens, 62% of boys and 55% of
girls consumed sugar-sweetened soda on the previous
day. (source: nalini ranjit et al. “dietary and activity correlates of sugar-
sweetened beverage consumption among adolescents," pediatrics published
online sep. 27, 2010.) when asked to compare the boys'
percentage with the girls' percentage, two students gave
the answers below. show how each student computed
the percentage.
alma: the boys' percentage is 7% bigger than the girls'.
bill: the boys' percentage is about 113% of the girls'.

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

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
