There are 200 ounces in 6 liters. How many milliliter (ml) are in 6 liters? (How to do in dimensional analysis?)

Dima020 [189]

9514 1404 393

Answer:

6000 mL

Step-by-step explanation:

The prefix "milli-" is an SI standard prefix meaning 1/1000. So, 1 mL = (1/1000)L.

When doing dimension changes, you always want to use scale factors that have a value of 1, which is to say the numerator is equal to the denominator. For converting liters to milliliters, the scale factor you want will have mL in the numerator and L in the denominator:

(1 mL)/(1/1000 L) or (1000 mL)/(1 L)

To do your conversion, multiply your liter volume by this factor.

$(6\text{ L})\times\dfrac{1000\text{ mL}}{1\text{ L}}=\dfrac{6\times1000\text{ mL$\cdot$L}}{1\text{ L}}=6000\text{ mL}$

6 liters is 6000 milliliters.

You will notice that the dimensions "L" cancel, which is the point of the exercise.

<em>Additional comment</em>

6 L is closer to 202.884 fluid ounces. The conversion factor is ...

$\dfrac{128\text{ fl oz}}{231\text{ in}^3}\times\dfrac{1\text{ in}^3}{(0.254\text{ dm})^3}\times\dfrac{1\text{ dm}^3}{1\text{ L}}=\dfrac{128\text{ fl oz}}{3.785411784\text{ L}}\quad\text{exactly}$

When solving a real word problem to find a person's age, would a negative solution make sense ?

mariarad [96]

NO, nobody could be negative something years old. For example, nobody could be -2 years old. That just means they are not even born yet.

Suppose seven pairs of similar-looking boots are thrown together in a pile. What is the minimum number of individual boots that

Vadim26 [7]

Answer:

8 individual boots must be picked to be sure of getting a matched pair.

Step-by-step explanation:

Step 1: Using the pigeonhole principle.

The pidgeonhole principle states that if n items are put into m containers, with n > m, then at least one container must contain more than one item.

A good illustration of the pigeonhole principle is the number of gloves one can have. For example, if one has three gloves, then one must have at least two right-hand gloves, or at least two left-hand gloves, because one has three objects, but only either a left hand or a right, two options of handedness to put on the gloves. Thus the third glove must be a pair of either the right-hand or left-hand glove

Step 2: Determining n and m

Since there are 7 pairs of boots, there will be 7 × 2 individual boots; n = 7

Now since there cannot be more than 7 pairs of the boot, m = 7

Step 3: Determining the minimum number of individual boots that must be picked in order to get a pair.

After all the 7 individual boots have been picked, the next individual boot picked must be a pair of one of the 7 boots picked. Thus, 7 + 1 = 8 individual boots must be picked to be sure of getting a matched pair.
