Question 335852: I have a chance to buy a 23 inch or 24 inch diagonal monitor for my computer system. Each monitor has a 16:10 ratio (Wide screen). What are the measurements (L, W, and Area) of each monitor? Which has the biggest area?
The only thing I could think of to try would be to use the pythagorean theorem as a first step, but then that leaves out the ratio part of the question, so I think that may be wrong. We have recently studied quadratic equations, so maybe I'm supposed to put it in that form to solve? I'm really lost!

Question 337092: Hi- I teach Adult Basic Education, mostly I help students pass the GED test. I am no Mathematician, and sometimes I get a question that I can not explain the Mathematics behind solving. This is an example of one such problems.
James Torres works in an electircal equiptment factory and does the final assembly on power trasfer units. He keeps a log of the number of units he completes each day. He works five days a week. Below is his log for the week of October 2 through October 6.
Production Log
Name: James Torres
Week: 10/2-10/6
Date No. units Assembled
10/2 12
10/3 15
10/4 18
10/5 17
10/6 16
Weekly total ______
Daily average ______

Here is the question:
The total for 10/3 is how much higher than the total for 10/2?
a. 3%
b. 12.5%
c. 20%
d. 25%

The answer is d. 25%.. . but WHY? The only rational I can come up with is 3 is the difference of 15 and 12, and 3 is 25% of 12. But why do I do that to solve this problem? How do I explain this to my students? Most of my students are visual learners so anything I can do to help me understand this, will in turn help them..
Thanks so much for taking the time to explain this to me, I really appreciate it.
