Ellen is playing a video game in which she captures butterflies. there are 3 butterflies on screen, but the number of butterflies doubles every minute. after 4 minutes, she was able to capture 7 of the butterflies

Step-by-step explanation:

Ellen is playing a video game in which she captures butterflies.there are 3 butterflies on screen, but the number of butterflies doubles every minute.after 4 minutes, she was able to capture 7 of the butterflies

Initial buttlerfies =3

Since doubles every minute, the no of butterflies follow a geometric progression, with first term =3, and common ratio =2

Hence in 4 minutes no of butterflies = 3(2)^(4-1) = 3(8) =24

So in 4 minutes no of butter flies =24

NO of buttlerflies captured = 7

Remaining butterflies = 17

i dont know

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
