Math Is Fun Forum

hey, no, I don't know what that is. Tell me.

Oh wow, thanks for posting the pics. I saw red clay in the first one. This last pic? Have you ever climbed it or trailed there? Found anything interesting there? I would love to see Egypt someday and an actual cave wall. I am a sponge for learning that stuff. Took both Geo. courses and an anthropology one thus far. Nature is the best!

I love to search for fossils. In Dec., it was about 24* when I went to see my Mother. I climbed in and out of creekbeds and never felt the cold at all. I guess it's the euphoria. My son sits in the car while I wander around in the creek. It's one of those deep beds that is dry in places, yet the water still flows. It is a high for me, since a kid there. Same place. I am going when school is out. Weather will be hot this time.

It is neat when you think about it. The earth has gone through many changes since the beginning. Ice age, dinosaurs, extinction. It was under water, and someday after humans are gone, it will be again.

Hello, so if there are bats, there are caves. Do you have pictures of the bats? I would be dragging out the camera and observing them, no doubt.

It's beautiful! How did you do that?
It is late and I am still typing.

Hello, yes it looks like that X. The numbers are horizontal in the center across the x.
Sorry about your connection problems. I know what you mean.

Good morning. My eyes are not open, I can feel the keys though. Went to sleep with pc on, woke up with all the web windows still open.

Just need sleep, i think.

Thank you. I am still awake.
At a point on the ground 15 ft. from the base of a tree, the distance to the top of the tree is 1 ft. more than 2 times the height of the tree. Find the height of the tree.
The height of the tree is ___ft.
(Simplify your answer. Round to the nearest foot as needed.)

Yes, it was exact. Wonderful!
Here's another from a tired person. LOL

If the hypotenuse of a right triangle is 2 m more than the longer leg, and the shorter leg is 10 m long, find the length of the longer leg.
The longer leg is ____ m.

Will try.
For any integer n greater than 1, (2n, n^2 -1, n^2 + 1) is a Pythagorean triple. Use this pattern to find the Pythagorean triple generated when n = 8.

The Pythagorean triple is (____,____,____)
(Simplify your answer. Use ascending order.)

Thank you. I am not meant for math, yet it is necessary. So what is the answer, it's a beautiful formula, but it won't take it for sure. I guess I am just tired.
It still refused to take the other answer too. LOL

I don't really understand the Pythagorean thing, I am working on another one of them now. A triangle. I think we had this in Algebra last semester. Now, it resurfaces in this math class too. I appreciate your help. I think I have only worked five or six this evening, have to finish this up so I can finish the other math project.
