The 'I need a distraction' thread.

thats why i liked it, i wasn't bullied THAT much for being different

[Shirayuki]

kindergarteners were still jerks though...

A segment with endpoints G(-2, 3) and H(4, 7) is dilated by a scale factor of 2/3 with center of dilation (0, 0). What is the sum of all the coordinates of G’ and H’?

the fluff is this?

[Shirayuki]

i love how i've been playing so much in the arcade but i still don't know how to delete my scores

[nonperson]

The answer is 42.

Why do you want to delete your scores?

[Shirayuki]

it says to delete all but your highest score

[Cacoethes]

In all my over 10 years on this site, I have never played in the arcade!

[nonperson]

Going to start now? =P

[Cacoethes]

Not while I'm at my nanny's but maybe when I get home!

[chinahorse]

Shall I have cocopops or toast?

[nonperson]

Cocopops! Or both.

[chinahorse]

I got coco pops. Too cold downstairs to wait for toast.

[Cacoethes]

Mmmm coco pops

[Shirayuki]

np you were so close! the answers actually 8, and here's why (it was on a mathcounts website and they just answered it)

A segment with endpoints G(-2, 3) and H(4, 7) is dilated by a scale factor of 2/3 with center of dilation (0, 0). What is the sum of all the coordinates of G’ and H’?

When a point is dilated by a scale factor of k about the origin, we multiply both the x- and y-coordinate by k to determine the coordinates of the image. So, the image of G(-2, 3) dilated by a factor of 2/3 about (0, 0) is G’((-2)(2/3), (3)(2/3)) = (-4/3, 2). The image of H(4, 7) dilated by a factor of 2/3 about (0, 0) is H’((4)(2/3), (7)(2/3)) = (8/3, 14/3). The sum of the coordinates of G’ and H’ is -4/3 + 2 + 8/3 + 14/3 = (-4 + 6 + 8 + 14)/3 = 24/3 = 8. Alternatively, we could multiply the sum of the coordinates of G and H by 2/3 to get (2/3)(-2 + 3 + 4 + 7) = (2/3)(12) = 8.

wow, i guess i'm the only one who's played in the arcade- ALOT ^^"

[nonperson]

Nah, the answer is always 42.

[Shirayuki]

hows it always 42?

[chinahorse]

Morning all :)

[nonperson]

Because 42 is the meaning of life, the universe and everything. =)

Morning Lillie! How're you?

[tamobhuuta]

Morning china, how are you?

[tamobhuuta]

Morning np too :)
