<p>thanks a lot again!!!! (sorry if that's a lot at once hehe)</p>
<p>You'll probably get more answers if you post some of the problems (unless they're diagrams or something). Not everyone has a copy of the blue book (espcially those of us who took the old test)</p>
<p>oh okay! here i go:</p>
<h1>6- the eggs in a certain basket are either white or brown. if the ratio of the number of white eggs to the number of brown eggs is 2/3, each of the following could be the number of eggs in the basket except: 10, 12, 15, 30, or 60</h1>
<h1>7- if 18 x square root of 18= r x square root of t, where r and t are positive integers and r>t, which of the following could be the value of rt? 18, 36, 108, 162, or 324</h1>
<h1>16- let function h be defined by h(x)= 14 + (x^2)/4. if h(2m)= 9m, what is one possible value of m?</h1>
<p>*17- (this one involves a pic so i can't post it, but hopefully somoene has the blue book and can help me out hehe)</p>
<h1>18- if the 5 cards shown above are placed in a row so that the one solid card(third one in row) is never at the either end, how many different arrangments are possible?</h1>
<h1>8- also involves pic</h1>
<h1>12- pic</h1>
<p>okay thanks a lot!!!!!!!!</p>
<h1>6 should be 10. the number of eggs in the basket should be divisible by 3, or else when you divide into white and brown eggs, you'll be left with half or third eggs... and that'd be a very gooey mess. :)</h1>
<p>Number</a> 7 and 18
Number</a> 16</p>
<p>crash blair, thanks that was a really simple explanation that made things easier. thanks for your help :)</p>
<p>Actually the answer to #6 is 12.</p>
<p>If the ratio of white eggs to brown eggs is 2/3, that means that:</p>
<p>A) the ratio of white eggs to TOTAL eggs is 2/5 (2/ [3 +2])
B) the ratio of brown eggs to TOTAL eggs is 3/5 (3/ [2 + 3])</p>
<p>This shows that the total number of eggs should be divisible by 5 (If you want to check, set up a proportion: 2/5 = x/any number that is divisble by 5...x represents the number of white eggs out of the total number of eggs). 12 is not divisible by 5 so that is the answer (you can check this with a proportion if you want: 2/5 = x/12....you will not get a whole number answer).</p>
<p>lol wow thanks for catching that mistake lildez!! wow</p>
<p>No problem arbortrees06...I have time for one more:</p>
<p>Since 6, 7, 16, and 18 are answered I'll do 17:</p>
<p>From 7:15 to 8:45, there are:</p>
<p>1 "on the Hour" (8:00)
2 "Half Hours" (7:30 and 8:30)</p>
<p>That means in the first column, n is 8 because the nth hour is 8:00.</p>
<p>For the "Chimes n Times on the nth Hour," you have: 8 chimes x 10 Type A clocks = 80 chimes and 8 chimes x 5 Type B clocks = 40 chimes.</p>
<p>For the "Chimes Once on the Hour," you have 1 chime x 3 Type C clocks = 3 chimes.</p>
<p>For the "Chimes Once on the Half Hour," you have 2 chimes (remember there are 2 half hours between 7:15 and 8:45) x 10 Type A clocks = 20 chimes and 2 chimes x 3 Type C clocks = 9 chimes.</p>
<p>Now just add the chimes up: 80 + 40 + 3 + 20 + 6 = 149 chimes.</p>
<p>oh... whoops. xD sorry about that!! :( and this is why i never ace anything XD</p>
<p>lildez, thank you so much for that, i actually understand it now! ha! wonderful
crash blair: don't be so hard on yourself, it was just a small mistake, i bet your method works well for other problems :)</p>
