Algebra word problems

It was an x rated movie, my instructor showed the class this morning, or half of one to be continued. I would not be surprised if someone didn't report her. It was certainly out of place for class with kids, some right out of high school.

Here's one about carpet: They are mixed up, it seems.
Suppose carpet for a 6 ft. by 14 ft. room costs $500. Find the cost to carpet a room 24 ft. by 56 ft.
The cost to carpet the room is $_____.

Yikes, x-rated! She could be suffering from some sort of stress. Does she Mhaaawuaaahhh a lot like a mad scientist?

No, she is an older woman. She is not the typical teacher in college for sure. I do not understand her at all, as far as professors go. She has a doctorate.

bobbym · 2011-04-27 17:47:35

I will not tell on her. But tell her if she comes in here she will have to mind her p's and q's.

Thank you.
you are in another state. She does not do boards at all. LOL

Length is 48 inches.

Width is 24 inches.

Thank you.
How high is a tree that casts a 33-ft. shadow at the same time a 4-ft. post casts a shadow which is 3 ft. long?
The tree's height is ___ft.
(Round to nearest tenth, if necessary.)

bobbym · 2011-04-27 18:54:02

44 ft high.

Thank you! Did your movie turn out okay?
Given a right triangle with legs a and b, and hypotenuse c, find the missing side.
a = 14, b =48
c=_______
(simplify your answer, type as an integer or a decimal.)

bobbym · 2011-04-27 19:03:30

c = 50

I am only 3 / 5 through it.

Thank you.
Here is a complicated one. I hope i type it correctly.
If m is an odd positive integer greater than 1, then ( m^2 -1 m^2 + 1) is a Pythagorean triple.
(m ____._____________
2 2
Use this to find the Pythagorean triple generated when m = 15.

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

bobbym · 2011-04-27 19:38:22

You mean 2m.

survival · 2011-04-27 19:56:24

There's an m, before the rest and it's laid out like division. The m^2 is at the top after the first m, but they are not together. I hope that makes sense. I have never seen one like this.

bobbym · 2011-04-27 20:01:32

Hi;

It does not. The formula for the pythagorean triples from Euclids time is:

I need an m and a n. In other words I need two numbers.

You mean this expression:

This gives 15, 112, 113 as the pythagorean triple.

survival · 2011-04-27 20:07:51

It says If m is an odd positive integer greater than 1 (that could be one of the numbers you need) then later it says "Use this (the problem) to find the Pythagorean triple generated when m= 15. (15 could be the other one you need?)
It's beautiful, the way you typed it out. Like art. The first m had a comma after it, before the problem began, yet it was part of it.

Please check the post right above yours it answers the question fully.

survival · 2011-04-27 20:15:05

It's exact! You are a genius with Math.
Thank you!
I hope this is not tiring you out.

Nope! Just not a product of the new math. I remember I told you that.

survival · 2011-04-27 20:19:23

Yes, I think you did mention that.
I guess i will sleep now; it is late.
ps For real I dreamed about math the other night. In the dream, money was not money, people paid with math symbols. I know that is crazy!!!!See ya tomorrow which is now today.

I do not mind. I taught my brother and he is better than I am. A real expert in Vector Calculus and Differential Geometry. I am happy about that.

survival · 2011-04-27 20:49:32

To be able to know math would be a gift i think. I have always had trouble with math, especially algebra. It has a beautiful language of its own though.

That is not how it works. Everybody has to work hard at it.

survival · 2011-04-28 07:06:23

Hello,
I worked on one problem an hour this morning and when i got the right answer, it was incredible. I have to work them out step by step and this is a big problem with deadlines.

bobbym · 2011-04-28 08:09:31

Hi survival;

That is very good. I am glad you are trying on your own.

survival · 2011-04-28 12:37:30

Yes, I do most things myself, but you think faster with math so I ask for help.

Find the measure of the supplement of 77 degree angle.
The measure of the supplement of a 77* angle is ___*.
(Simplify your answer. Type and integer or a decimal.

Thank you and I hope your day was a good one.
