Algebra word problems

103 degrees.

The day is not over yet.

survival · 2011-04-28 18:16:44

The day is over now. I guess the rooster will crow at sunup. I live in a residential neighborhood, yet someone used to have roosters and one would crow about 4 every morning. Sounded so strange, yet neat, like when i was a kid. We had chickens and foxes too. There used to be a pet skunk who would come to the back door and eat with the cats every night. It was cool and he was so beautiful. He was okay till he must have been in a bad mood, then he would release the skunk cologne.
I have not heard that rooster in a long time. I hope he's okay.
I finished my essay for tomorrow. Worked about 10 problems tonight. Thought I would leave you one.
*
A hotel is in the shape of a cylinder, with a circular foundation. The circumference of the foundation is 4 times the radius, increased by 104.88 ft. Find the radius of the circular foundation. Use 3.14 as an approximation for ii (symbol for pie. you know like pie r ^)
The radius of the foundation is ___ft.
(Simplify your answer. Type an integer or decimal rounded to the nearest hundredth as needed.)

Thank you. I hope you have a good night. Back to school tomorrow. Have to go in earlier so I will be sleepy.

Hi survival;

Roosters and chickens and foxes and skunks and cologne, I thought that was the math problem. Also it made me hungry, I love chicken. My Daddy was born in Bessemer Alabama so I have a little bit of Sgt. York in me. I might be a fixin to load my Kentucky rifle and head down your way to do some hunting.

r = 46 is what I get.

survival · 2011-04-29 10:41:00

It's a different world, but I don't live in Ala. I have ancestors who did though.
I hope your day was good. Mine was worse on the highway than anything else. Too much traffic.

If positive integers are chosen for r and s, with r>s, then the following set of equations generates a Pythagorean triple (a, b, c).
a= r^2 - s^2 b= 2rs c = r^2 + s^2
Use the values r =4 and s = 1 to generate a Pythagorean triple.
a=_____
Thank you.

bobbym · 2011-04-29 11:13:13

a = 15

It is early here and storming pretty violently.

survival · 2011-04-29 12:04:31

Do you have storm houses where you are?

What is the b part of the answer. It is asking for b.
Thank you.

bobbym · 2011-04-29 12:09:42

No, we do not have them. As you may have heard parts of the south are getting pummeled by severe weather conditions. As I understand it 328 people are dead.

b = 8 and c = 17

survival · 2011-04-29 13:08:18

Yes, the storms were tragic. I have a niece who lives near there, have not heard from her.

What is the diagonal is the diagonal of a rectangular room which measures 8ft. by 22 inches?
The length of the diagonal is ___ft. ___inches.
(Simplify your answer. Round to the nearest inch.)
Thank you.

bobbym · 2011-04-29 13:25:10

Hi;

Hope she is okay.

23 inches.

survival · 2011-04-29 13:29:55

She is only 19 and lives there with her b/f. Yes, I hope they are both okay.

It wants the Pythagorean theorem to determine the length in ft. and inches of that room.
Thank you.

bobbym · 2011-04-29 13:41:51

I am sorry, I read the problem wrong. 8 feet and 2 inches is the diagonal. Now what else does it want?

survival · 2011-04-29 13:59:56

Thank you.
it is not satisfied with the answer. It says, "use the Pythagorean theorem to determine the length of the diagonal in ft. and inches.

survival · 2011-04-29 14:13:52

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.

bobbym · 2011-04-29 14:18:51

I did.

8 ft = 96 inches.

Where c is the diagonal.

survival · 2011-04-29 14:36:42

Here's the mess I just made with the triple thing. It is a wrong answer.
For any integer n greater than 1, (2n,n^2 + 1) is a Pythagorean triple. Use this pattern to find the Pythagorean triple generated when n is 8.
I have _____16^2, 255^2, 257^2
Maybe that 16 should be 64^2?? or it's the other two that's wrong??
Thank you.

bobbym · 2011-04-29 14:42:36

Hi;

(2n,n^2 + 1) is a Pythagorean triple.

That is incorrect.

This is the formula I gave you.

So for any m > 1 then

is a pythagorean triple.

survival · 2011-04-29 15:01:05

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

8, 63 / 2 and 65 / 2 is a triple.

survival · 2011-04-29 16:04:33

Hey, it won't "take." Wonder why?

bobbym · 2011-04-29 16:15:53

Please write down the equation they give word for word. And the question word for word.

I am going to take a little break.

survival · 2011-04-29 16:25:00

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.)

16,63,65

survival · 2011-04-29 18:38:20

Thank you.
I am so tired. I have written so much today, my fingers hurt. My brain is tired too.

bobbym · 2011-04-29 18:38:43

Did it work?

survival · 2011-04-29 18:47:58

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.
