He is buying 6 different types of rockets, tiny, small, medium, large, huge and gargantuan. All quantities of rockets bought are positive whole numbers. He buys 2 more large rockets than medium rockets. The number of small rockets he buys is equivalent to the square root of the number of large rockets he buys. The number of tiny rockets he buys is equivalent to the number of large rockets he buys plus the number of small rockets he buys plus twice the number of medium rockets he buys. The number of huge rockets he buys is equivalent to (number of medium rockets he buys + number of tiny rockets he buys + number of small rockets he buys)</span></span></span><span style="font: 8.0px Helvetica; letter-spacing: 0.0px;"><sup><span class="Apple-style-span" style="font-size: small;"><span class="Apple-style-span" style="font-family: Times, 'Times New Roman', serif;">0.5</span></span></sup></span><span style="letter-spacing: 0.0px;"><span class="Apple-style-span" style="font-size: small;"><span class="Apple-style-span" style="font-family: Times, 'Times New Roman', serif;">.

There is a sales tax of 8% on each rocket. Joe does not buy more than 300 rockets. How much does he spend on the rockets?</span></span></span></div>Caleb N.http://www.blogger.com/profile/06412691014953572832noreply@blogger.com0tag:blogger.com,1999:blog-6489325605624459987.post-9444139380423749992011-10-13T11:11:00.000-04:002011-10-13T15:48:22.159-04:00Tetra Terror<span class="Apple-style-span" style="font-family: Times,'Times New Roman',serif;">Here is a new math puzzler.

If you think that you know the answer, please post it in the comments section.<br /><br />Blokies are a small, block like creature. Blokies are either orange or green. All blokies have a number on their back. Every hour, a blokie spawn happens. If the number of blokies the same color as a blokie is less than or equal to the number on that blokie, that blokie spawns a new blokie. The number on a new blokie depends on the blokie spawning it. If the spawner is orange and has an odd number on it, the number on the new blokie is three times the number on the spawner minus 1. If the spawner is orange and has an even number on it, the number on the new blokie is two times the number on the spawner minus 1. If the spawner is green and has an odd number on it, the number on the new blokie is three times the number on the spawner plus 1. If the spawner is green and has an even number on it, the number on the new blokie is two times the number on the spawner plus 1. There is an orange blokie and a green blokie, each with the number 1 on them. After 9 spawns, what will be the value of (sum of the numbers on green blokies)/(sum of numbers on orange blokies)? Please give your answer rounded to the nearest humdredth.<br /><br />The answer will be posted on Thursday.Caleb N.http://www.blogger.com/profile/06412691014953572832noreply@blogger.com0tag:blogger.com,1999:blog-6489325605624459987.post-21041556460207625872011-05-27T10:30:00.001-04:002011-05-27T10:30:02.299-04:00Schrodinger's M&Ms AnswerContained within this post is the answer to the puzzle posted on May 24th.
