• ### Using all 7 pieces of a tangram set, what design would have the smallest perimeter?

I have been working on this already, but I'm not sure if my answer is the smallest perimeter possible. I know the square is not the smallest since some of the shape's largest sides are exposed to be part of the perimeter. I have gotten the perimeter to be smallest using a hexagon shape (as seen here: http://etc.usf.edu/clipart/64500/64535/64535_hexag... ) but I don't know if there is a design with a smaller perimeter. Does anyone know how I could prove the design is the smallest perimeter?

• ### How long would it take to recover from a very late payment 90 days late on a cc? It's been a rough year. I went from a 749 to a 626.?

I also got a letter from another cc that they are closing the account (had balance totally paid off and \$3500 line of credit) due to the other card's very late payment dropping my credit score.

How long does it usually take to make regular payments to bring up the score?

• ### I'm looking for the name of a kids/teen book. I believe it is about fourth grade level.?

The boy picks the pocket of the wizard and, although he touches a magic stone, surprises the wizard by surviving. He becomes the wizard's apprentice. The wizard has been called in to town because of a very bad problem. He had been banished and his castle/house is not badly damaged. I did not get very far in the book before I left it somewhere, but I'd like to read the rest of it. Anyone recognize this?

• ### How do you describe the nth term of the pattern: 2, 2, 4, 4, 6, 6, 8, 8, 10, 10, etc.?

Alternatively, how would you find the nth term of the pattern:

0, 2, 2, 4, 4, 6, 6, 8, 8, 10, 10, 12, etc. ?

• ### Need help with a rational function?

Here are the directions:

Write a rational function g with vertical asymptotes at x = 3 and x = -3, a horizontal asymptote at y = -4.

I know the denominator has to be (x - 3)(x +3) in order to get the vertical asymptotes. I know the numerator needs to have the same degree as the denominator and the coefficient must be -4. So I got as far as -4x^2 on the top. However, I do not see where the answer has -4x^2 - 6 on the top. Where does the -6 come from?

• ### How do I ge the old version of Yahoo answers back?

I hate the new listings. It is too hard to find questions I can answer. The list of previously asked questions no longer seems to note which ones were selected as the best answer. Has that been removed?

The new format is confusing. How do I revert to the old version?

• ### Real life math - credit cost to me?

I am thinking about charging a computer to a high interest credit card to get a sale price. I'm trying to determine if I really will save in the long run, due to the interest. However, I'm not sure if I'm calculating this correctly. Is this correct? If not, an you explain what the actual cost to me would be?

\$830 - amount I need to pay. I will get a \$50 rebate in about two months, so actual cost is about \$780.

The regular price of the computer is about \$1200. So I am looking at an initial savings of 1200 - 780 = \$420.

Now, the problem is that I'd have to use a high interest credit card to do this. The interest rate is 19.99%. It is billed monthly. I expect to pay \$100/month, approximately paid off in 9 months.

Here is where I get confused:

Is this the correct way to calculate the total interest I will pay for the purchase?

A= P(1+ (r/n)^(nt)

assuming for 9 months, I figured

A= 830(1+(.1999/12)^(12*.75) I used t = .75 since 9months /12 months = .75

A = 830(1.01665833333)^9= 830(1.16031317) = \$963.06 with interest.

This looks like I would pay about \$130 in interest over the 9 months, but I don't understand how to figure in the fact I am paying off \$100/month, so each month the actual amount that would have interest charged would be less.

Is this the correct formula to determine the interest on a credit card? I posted this in the credit card section of Yahoo Answers, but I did not get any mathematical responses, so I'm posting it here. Please understand I already know I will pay no interest if I pay in cash. I also know that paying for non-essentials on credit is a bad idea, however this is needed for work so I have to buy it in the next two months. I really just want help with a formula and calculation of the interest that will accrue when \$100 payments are made with a 19.99% interest rate credit card. Thanks.
