For example: Because their bones are so weak, and their bodies so worn down, up to 90% of hens have broken bones or are hemorrhaging by the time they make it to slaughter. How do we figure out the actual number of hens? There's the 100% percentage. Tell me what you know and how to solve for numbers like this using the percentage.

Please help me answer the following problem.

A city, in the shape of a '+' sign, has 5 bus stations, one at each end of the cross and the depot in the middle. The east station is A, north is B, west is C and south is D, while the middle depot is O. All buses travel from O to A and back to O, then immediately O to B and back etc. When the bus travels from O to D and back, it instantly starts again and travels to A, continuing the course repetitively for 9 hours. The time it takes to travel to O to A and back is 11min, O to B and back is 4 min, O to C and back is 7 min while O to D and back is 4 min. A second bus leaves the depot O at 7:37, traveling the exact same route as the first bus, also for 9 hours. How many times between 8:00 and 3:00 do the buses meet?

Thanks for helping me.
If it is not clear enough, state it in your answer and I will add the details, or email me at my yahoo address.

Hello,
I am stuck on these two particular problems in dealing with radicals. I'm doing very well in algebra in general, but i'm getting stuck when it comes to roots and radicals. Could someone please check my work for me? I tried the best i could to figure them out. I would really appreciate it.

1.) Simplify-- √200x^3 = 10x^2√4x
2.) Find the product of (√3 -√2)(√3+√2) = √9 - √4

We are familiar with 3² + 4² = 5², right?
But there is also 20² + 21² = 29².

Is there a general algorithm that would generate x, y and z as solution to x² + y² = z² where x, y and z are co-primes into each other?

Please help me I really wanted to know.
