2/8 + 5/6 = 6/24 + 20/24 = 26/24 = 13/12 or 1 1/12

Do I have to use every number?

5+5+5     Add 5,  3 times

          Or

3+3+3+3+3   Add 3,  5 times

27*9=243

My name is Ethan, if thats what you're asking.

What model of calculator DO you have? I may be able to help, and this place does have scientific mode too...

4√63 / 6√36

Let us look at your examples:

4sqrt(63)=4sqrt(9 x 7). Notice that 9 is a perfect square. You can take its sqrt, which is 3 and multiply it by 4 outside the sqrt. So, it becomes: 3 x 4sqrt(7)=12sqrt(7), which is the same as: 4sqrt(63).

Now, the second example: 6sqrt(36)=6sqrt(6 x 6). Since 36 is a perfect square, you can take its sqrt, which 6. Then multiply this 6 by the 6 outside the sqrt, and you get: 6 x 6=36, which is the same as: 6sqrt(36). And that is it.

Use the key that says: √x. Enter your number first, then press that key followed by = key.

Since he is driving at 90 km/hr and his house is 30 km away, then he should cover that distance in 30/90=1/3 of an hour. Or,

1/3 x 60 minutes=20 minutes, he should be home.

Algebraic Equivalent:

ab=c, Where a is the amount of materials, and b is the number of people; c is the answer, essentially the amount of materials needed total to sustain everyone.

10 * $3 = $30

10 * $1 = $10

$30 + $10 = $40

$2/$40 = .05

You didn't ask, but the function would have a local minimum at A and a local maximum at B.

math is cool

The first part of your question is very simple. We simply find the PV of her 7 payments of $50,000 each @ 5% comp. annually=PV=$289,318.67. You use the common TVM formula to calculate this, which is:

PV=P{[1 + R]^N - 1.[1 + R]^-N} R^-1=PV OF $1 PER PERIOD.

The second part is a little more involved. However, there is also a TVM formula to calculate it directly, which I'm sure is in your textbook. However, we may not need it in this case. Because, her father's monthly payments double every month for 12 months, then we can solve directly for the first payment. If we put the first payment as P, then we have:

P x 2^12=$289,318.67. Solve for P.

P=$289,318.67 / 2^12

P=$70.63. This should be his first payment minus interest. Since the interest he got was 10% comp. annually, we have to convert this to a monthly compound, which comes to about 9.57%. 9.57/(12 x 100) +1=1.007975. This is the monthly interest rate. We divide the above payment by this and we should get his initial deposit: $70.63/1.007975=$70.08, which is his initial deposit.
