	4 carpenters can build 8 houses in 10 days.		2016-04-05
		From Kenneth: Hello: Here is my question: 4 carpenters can build 8 houses in 10 days. 2 carpenters can build how many houses in 15 days? Here is one solution: The number of houses built is jointly proportional to the number of carpenters and the number of days. So h = kcd where k is a constant. Substituting the given: 8 = k*40, so k = 1/5. Our formula is then h = cd/5. I'm not sure how to determine whether or not one unit is jointly proportional to any other unit. However, if 2 carpenters are unknown as in 4 carpenters can build 8 houses in 10 days. How many carpenters can build 6 houses in 15 days? What is the solution using this method? And likewise, if days are unknown, as in 4 carpenters can build 8 houses in 10 days. 2 carpenters can build 6 houses in how many days? I thank you for your assistance. Answered by Penny Nom.

	Compound interest		2010-04-21
		From Kenneth: Let's say that an investor has $1000.00 to invest for 3 years at a rate of 5% at compound interest. Here is the formula: M = 1000(1 + 0.05)^3 = $1157.62 If I want to change 1000(1 + 0.05) to (1000 + 0.05*1000) three times in a calculation instead of using (1 +0.05)^3, how would this be done? I cannot get (1000 + 0.05*1000) + (1000 + 0.05*1000) + (1000 + 0.05*1000) to equal $1157.62. I know that 1000(1.05)(1.05(1.05) will produce the answer, but I want to try to use the above non-factored calculation. Answered by Penny Nom.

	Building a pyramid		2000-02-26
		From Francis X. Hines Jr.: I am presently trying to build a pyramid. I can understand that the base has 90 degree angles on the first plane which is the outline of the square that makes up the floor. As close as I can figure the slope of each wall face is 35 degrees or 35.7 to be exact if I am correct by using 360 as the total of the three interior angles.Now , I run into a compound angle where the corners meet what would be the angle created by the two 35 degree angles that would allow for the 90 degree edge to continue. Because I'm working in three dimensions I also need to be sure that my math would be correct when I substract 35 from 90 to aquire the angle of the narrow edge as to allow for a 90 degree surface to be present ..to allow for another level to be added with only the base line being shortened. I hope you can understand what it is that I'm asking assistance with.I would greatly appericate your help. Answered by Chris Fisher.
