How many meters are in a kilometer? math class ! a man is running in a triathlon. he runs 500 meters, swims 300 meters and cycles 10 kilometers. what is the total distance of the race in kilometers? ?

1 Kilometer = 10 Hectometers
= 100 Dekameters
= 1000 Meters
1 Meter = 10 Decimeters
= 100 Centimeters
1 Decimeter = 10 Centimeters
1 Centimeter = 10 milimeters

Just to give you a table of conversion.

Now to get the answer.

500 Meters + 300 Meters = 800 Meters
800 Meters + 10 Kilometers

You can't add numbers with different units, so you're going to have to convert. So the equation would end up being:

800 Meters + 10000 Meters = 10800 Meters

Since you have to answer it in Kilometers, you're going to have to convert it again to Kilometers. Since 1 Kilometer is equal to 1000 Meters, yo would have to divide 10800 by 1000. So it would turn out like this:

= 10.8 Kilometers

Now, here's what we've done:

500 Meters + 300 Meters + 10 Kilometers
= 500 Meters + 300 Meters + 10000 Meters
= 10800 Meters
= 10.8 Kilometers

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
