Counting money what is cents

what are cents, one cent is 1 unit of money subdivide by 100 if you have dollars one cent is 1/100 of a dollar, if you have Brazillian money one centavo is one real subdivide by 1/100. So you are counting cents when you have 100 cents is the same that one dollar for American money and one real for Brazillian money, 2 coins of 50cents is one dollar or one real in Brazilian money, and 1000 in cents are 10 dollar or 10 real, 2000 cents is 20 dollar.

Ps.:Would be always that way I think that when in Brazil was reis the bill worth a lot and the coin was 1/1000 of the bill.

In calculus how to convert the broken part of the hour

And is that let's say that you are working with a function that deals with time like hours and in one point the time isn't integer like 5,34 hours, looking for that number I know that I have 5 hours but what is 0,34 hours isn't minutes here the hour is divide by one hundred and not for 60 so haven't resemblance, so what do with the fraction portion you only have to get the fraction and multiply by 60 so 0,34x60 and the result is minutes and you gonna find 20,4 the integer is minutes 20 minutes and the fraction you still can multiply for 60 to have seconds and is 0,4x60 = 24 seconds. So we have 5:20:24. Rute Bezerra de Menezes Gondim

Ps.: I find a so beautiful number that hasn't broken part after the seconds but if have what I could call it you can call it centesimos of seconds and let be, at that point isn't divide by 60 but by one hundred. And 40graus12'23'' - only one apostrophe is minutes and two is seconds.

como converter km/h em m/s

How to convert the velocity of one system to another 

For an instance the km/ in m/s, how I already said one kilometer is 1000 meter.

1 hour is the same that 60minute multiply for 60seconds that gives us 3600 seconds.

So in one hour, we have 60 minutes and in one minute we have 60 seconds how many seconds we have in one hour 60x60 that give us 3600 seconds, in one hour we have 3600 seconds.

one kilometer is 1000meters and one hour is 3600, so one kilometer/hours so let's make our formula where is km replace by 1000meters and where is 1 hour replace by 3600seconds, and we gonna have 1000meters/3600seconds. Rute Bezerra de Menezes Gondim

Algorithm how to memorize ordination

And is that the aux the number 'a' and the number 'b'.

And is that the command is aux receive 'a' and 'a' receive 'b' and 'b' receive aux, that is 'a' so 'b' receive the 'a'.

something like that 

aux = a; a = b; b = aux;

And to memorize if aux is equal 'a' the aux is erased and 'a' and aux have 'a';

And if 'a' equal 'b' what is in 'a' gonna be erased and 'b' and 'a' gonna have 'b'.

and for the end 'b' equal to aux so what is in 'b' will be erased and 'b' and aux gonna have the same value that was what aux receive from 'a', but what matters is 'b' and who cares what is in aux that is there only to make the swap. Rute Bezerra de Menezes Gondim
