<p>the distance formula did work</p>
<p>the coordinates were (-10, 4) and (2,-1) </p>
<p>-10-2= -12
4--1=5
(-12)^2+(5)^2=144+25=169
square root of 169 is 13</p>
<p>wow, duh!! NEGATIVE 10.... I had 10 the whole time. Okay, I'm an idiot... and I checked my coordinates over and over again.</p>
<p>oh yikes.. ithought 9 was the answer..bc sometimes answers on the ACT can be decimals but they usually just round them off..</p>

How about the other math question about how many times did you have to take a marble or sth out to guarantee 1 of each color. Was it like 12?

</p>
<p>it was three. its three colors. you have to at least pick three in order to get all the colors. they ask for the minimum, remember?</p>
<p>lol
i did the same thing! when i finally figured it out, i almost screamed aloud! :)</p>
<p>wait..so distance formula DID work?</p>
<p>^^^i seriously cursed out loud when i figured it out.</p>
<p>this board should be a chat btw..better than refreshing every few seconds.</p>
<p>but the question said to GUARANTEE that you get all colors...there were like 8 blue, 3 green, and 2 red...so to guarantee that you get every color by drawing randomly you have to pick 12 right?</p>

<p>Yeah, but what if you picked red all three times... I think red had 8, something else was 3 and the last one was 2. So to guarantee picking one of each color, 8+3+1 -> all red plus all 3 and last one from the 2. idk, is this wrong?</p>
<p>no, its definitely not 3.. it said the minimum number to GUARANTEE you got all 3 colors. Picking 3 in no way guarantees you get 3 different colors.</p>
<p>nvm. (10char)</p>
<p>mhh, I agree :) and yes, spaz, it sucks to refresh every 1 second</p>
<p>but they asked for the minimum marbles you have to pick in order to get all three colors. you're thinking too much. i'm quite sure i read the question correctly. i can read.</p>
<p>i got 12 too, ticktock</p>
<p>y'all have AIM?</p>
<p>if you all have aim we can do a buddy chat haha</p>
<p>The answer is 12.</p>
<p>it didn't use the word "guarantee" without reason
you can pick 3 and not get 3 different colors, which means that its not guaranteed.</p>
<p>ticktock is right. the answer is 12. i had a question just like that in my SAT prep book. the key word is guarantee.</p>
<p>consider picking colors out of the bag.
first: blue
second: blue again
third: blue again
fourth: blue again
fifth: blue again
and so forth because there were eight blue. then all the greens. and finally one red. that makes twelve.</p>
