How many years will it take $39,450 to double at an interest rate of 3.2%, continuously compounded? *
taurus [48]
Years = natural log (total / principal)  / rate
Years = ln (78,900 / 39,450) / .032
Years = ln (2) / .032
Years = 0.69314718056 / .032
Years = <span> <span> <span> 21.6608493925 </span> </span> </span>

5500 milliliters equal how many liters show work
Eva8 [605]

Answer:

5.5 liters

Step-by-step explanation:

1 milliliter equals to 1/1000 part of a liter, which is 0.001 liter.

1 milliliter = 1 * 0.001 liter

So if you have 5500 milliliters that means it equals to 5500 times one milliliters and 1 milliliter = 1 * 0.001 liter, so for 5500 milliliters it is 5500 times as much

5500 * 0.001

5500 * 1/1000

5500 / 1000

5.5 liters

As long as you know this number 0.001 , then it is easily to calculate between liters and milliliters.

EXTRA:

To convert from amount A which is given in a certain quantity, to another quantity, you sometimes have to multiply and in other cases you need to divide by a certain factor. The factor defines the relationship between the quantities.

Suppose you have 1000 times 1 milliliter then you can find the amount in liters by multiplying that number of milliliters times 0.001.

It is easy to see that

1000 * 1/1000

1000 / 1000

= 1 liter, but that is easy, because I choose an easy number for the amount of milliliters to convert into liters. But it works exactly the same for any amount!
