<p>^Yeah, it had to be less than 30 degrees. But it was 42/60 * 30 = 21</p>
<p>oh dang! I misunderstood it.</p>
<p>You could basically just figure it out by estimating. I mean if 60 mins is 30 degrees its easy to estimate the 42 mins especially since the answer choices made it obvious. Thats what I did at least.</p>
<p>i think i just set up a proportion, which I think is the right thing to do…</p>
<p>
</p>
<p>If you set up a proportion equation just for the hour hand only, that would’ve done the job.</p>
<p>I got 252 first. Then I realized the hour hand does not move that much in 42 min.</p>
<p>wHAT IS the circle probability question?? 1/9 thing?</p>
<p>3 circles are concentric (have the same center) with the smallest have a radius of 1, the next a radius of 2, and the last a radius of 3.</p>
<p>What is the probability that the point selected is INSIDE of the largest circle AND INSIDE of the smallest circle.</p>
<p>Smallest circle area = pi *r^2 = pi * 1^2 = 1 pi
Biggest circle area= pi * r^2 = pi * 3^2 = 9pi</p>
<p>Probability = 1pi/9pi = 1/9</p>
<p>can anyone go over the gallons of gas problem? dont remember it too well, want to make sure i got it right</p>
<p>@ nymets71993 : I believe the answer was 9.4, but I don’t remember the actual numbers used to get it.</p>
<p>When a car is 66% of its fuel, it uses X gallons, when it is 70% is uses Y gallons</p>
<p>how much would it use if it was 60.</p>
<p>The answer was D, 9.4</p>
<p>From finding the slope from the points and using point slope formula and plugging 60 into the equation and finding the gallons used, which is 9.4</p>
<p>The question said something like that I dont remember it exactly.</p>
<p>Oh, right! I’m pretty sure i got it. so far 6 wrong… i assume though that the 30 talked about on the thread were the toughest anyways</p>
<p>^Yeah definitely, no one remembers the easy questions.</p>
<p>I think this question was extremely tough for an easy question:</p>
<p>If Bob buys 2 boxes of candy worth 8 dollars each, and he has a 10 dollar bill, how much change would he expect to get?</p>
<p>hey guys for the ratio of the ball dropping i thought it went 270 120 80</p>
<p>Well, if he came to my store, he wouldnt get any change back. and if he asked for change, I would take his money and the candy bars and tell him to get an attitude adjustment.</p>
<p>Jokes aside, free, that question wasn’t on the exam right? Cus I dont remember it lol</p>
<p>And no, it went 270, 180…</p>
<p>^yes it definitely went from 270 to 180 - and was a geometric sequence with a difference of 2/3</p>
<p>oh drats haha ^
missed 1 then</p>
<p>Could someone explain the question asking for a number that would give you infinite ways or something like that? How do you do that??</p>
