Use dimensional analysis to check your equation before multiplying. Convert 5021 centimeters to kilometers.

So in problem six, we need to convert 50 to 1 centimeter in tow. Equal INGE kilometers. So how many kilometers is equal to five? Zero to a one centimeter. So we can convert like this. 50 to 1 centimeter that now we need toe. Ah, eliminated the centimeter term. So? So we have one meter divided by 100 centimeters. So one meter is equal to 100 centimeter and we can convert Dutch into, um what one kilometer and divided by 1000 two meter. So one kilometer is equal to 1000 meter. Then now we can eliminate the common units like centimeters and a meter than we eliminate meters. So finally we get your in terms off. Kilometer is equal to toe 0.5 0 to 1 kilometers and we can further right in this particular form, like 5.0 to 1 into a tender pour minus two kilometer. So this is a scientific way off representing the number so 50 to 1 centimeter is equal to five points or 21

Okay, There's several unit conversions here, all with the metric system prefixes. If we have 357 milliliters, then there's 1000 milliliters per leader. So we have 10000.357 leaders. We have 25 killer grounds. For every kilogram there's 1000 grams and for every gram there is 1000 milligrams. Then we get 2.5 times 10 to the seven milligrams. Then we go to see see, we start with 3 35,007 metres cubed every centimeter cube. There's a mill leader and for every 1000 milliliters there's a leader. So it's just 35 leaders. Pretty. We have 2.46 leaders. There is 1000 milliliters per leader and for every Miller leader there's one centimeter cube. So 2460 centimeters cubed for E. We have 250 micrograms. Every micro for every gram. There is one times 10 with six micrograms. So we get 0.25 or 2.5 times 10 to the negative four grams. In the last one. We have 250 micrograms. For every Graeme, there's one times 10 of the six micrograms and for every kilogram there's 1000 grams. So we end up with 2.5 times 10 to the negative seven kilograms.

To answer this problem. I'm going to start by converting the time unit because there are 60 minutes in an hour. You know that there are four point a times 60 courts per hour. This is equal to 200 a. D A. Courts per hour. Now to convert cords two gallons, you know that there are four chords in a gallon, so there are 200 88 divided by four Galan's for our this is equal to 72 Galan's per hour, and that is your answer.

Hello. So today we're gonna be talking about how um dimensional analysis can be used to solve problems. So first, it's important to know what dimensional analysis is. Dimensional Analysis is a systemic approach to problem solving that uses conversions factors to move or convert from one unit to another. So, for example, let's say I have 34 inches and I want to know how many feet do I have? Well, if I know that you know, for every one foot there's 12 inches. Well, then I can use dimensional analysis to convert between the two units of measure. So here is a simple way that can do this 34 inches over one. And then I always want to put the unit that I'm trying to get rid of, in this case, inches on the bottom so that I can cross multiply that unit out. And I put the unit that I want to keep my answer in on top so that it stays in my final answer. So if I know that for every one foot there's 12 inches, then all I have to do is multiply across the top, multiply across the bottom and then divide the top by the bottom. So now it should be 34 divided by 12 which is equal to 2.83 feet. And that's your answer. I hope that helped.
