I suggest you adopt the decimal clock. 0.1 hour (6 minutes) will be $3.50 or 0.05 hour (3 minutes) will be $1.75 and once you have a policy of using those decimal units, time and therefore the cash amounts will be rounded up to the nearest 0.05 or 0.1 hour.

To answer your question use a calculator and divide the required amount by $35 to obtain a decimal fraction of an hour, in this case $23 will buy 0.657 hour which for practical purposes is an unwieldy figure and for most purposes be rounded up to 0.7 hour (42 minutes).

If greater accuracy is required 0.657 x 60 (minutes) = 39.06.

Lots of workshop environments use the decimal clock and vehicle standard repair times and the resulting charges are decimal, the majority to 0.1 but some to 0.05.

I hope this is helpful...

You cannot type a percentage sign, you must use the decimal form. 50%=.50, 35%=.35, etc.... (Divide you percentage by 100)

Seconds: Subtract 12 from 35 to get 23.

Minutes: Subtract 23 from 45 to get 22

Hours: Subtract 0 from 2 to get 2.

Put the three together to get 2.22.23

This one was easy because there was no need for carry. If you do have to carry, just make sure you carry 60. Otherwise, it's exactly the same as when you learned subtraction in second grade.

Some calculators have conversions between decimal degrees/hours and degrees/hours:minutes:seconds. If you have such a calculator, you can convert both numbers to decimal, subtract, and convert back. Since you didn't specify what calculator you have, I can't tell whether this is an option for you.

You just select [MODE] use your left arrow if needed to select [Norm]. You might want to look at the other mode settings to select the ones that apply to the type of math your doing. But, [Norm] will put you in straight decimal form. To escape out of the Mode screen after you select [Norm], just [2nd][Clear] to quit should take you to Home screen.

There is a button there that says "S<=>D". Compute it first and when the result is in fraction, press this and it will be in decimals. This button is just above the DEL button.

For a TI-86

Converting rectangular to polar

Press "2ND" and then "MORE" for the MODE screen

Highlight PolarC and press "ENTER"

Quit that screen.

Now ready to go.

A example of converting 5+j6

Enter "(5,6)" in the calculator and press "ENTER"

Should get (7.81024967591*angle*50.1944289077)

Converting polar to rectangular

Press "2ND" and then "MORE" for the MODE screen

Highlight RectC and press "ENTER"

Quit that screen.

Now ready to go.

A example of converting 5*angle*35

Enter "(5*angle*35)

Should get (4.09576022145,2.86788218176)

Note

*angle* is the symbol when you press "2ND" then ","

Note 2

To round the an decimal places press "2ND" then "MORE" for the MODE screen and on the line that says float, choose a number on that line for the number of decimal places you would like to have.

This is a common starter challenge in college and high school programming classes. While i'm not willing to code it for you, I can show you the methods you'll need to understand in order to approach the problem. The easiest way of doing this is by using a brute force method. Just keep testing the number to see if the remainder after dividing it with a number lower than it is zero. If so, it's a factor.

For example, If the number is 35 then pick a number just one lower than it that's not the number 1. Now divide the two numbers. 35/34 = a number with many decimal places after it, which means its not one of the factors of the number. However, eventually, you'll approach the number 7, and 35/7 = 5. This number has no decimal, meaning it IS a factor of 35, and also the largest non-zero factor of 35. Your algorithm can now stop, since it found the largest non-zero number.

Here's some pseudo-code:

int largestfactor(int number) {

int temp = number;

for(temp - 1; temp>=1; temp--) {

if (number % temp == 0) return temp

}

return temp

}

Something like that, with some bug tweaks will do it. The "%" sign is called a modulus. It's a standard c++ operator. Good luck, and remember to vote Fixya if you liked it.

The wikipedia article that helps you with better and more effecient algorithms can be found here.
