Well,
The distance from the earth to the moon, FYI, is over 200,000 miles. That is a LONG distance. We are trying to find a reasonable unit of measurement.
What do we mean by "reasonable?" We mean that that unit should be able to express the distance as a number that is not huge or tiny. In other words, we want it to be as close as possible to 1.
mm, or millimeters, is a tiny unit. It is not reasonable.
cm, or centimeters, is also a tiny unit. It also is not reasonable.
m, or meters, is also a relatively small unit. It also is not reasonable.
km, or kilometers, is the largest of the four. In km, the distance from the earth to the moon is about 363,000 km. That's not too bad.
However, if these weren't the only options, I would choose Mm, or megameters, which would put the distance at 363 Mm.
The correct option is D.
Answer:
4500
Step-by-step explanation:
multiply the amount of times the heart beats every minute and multiply it by how many minutes which is 60 so 75 times 60 is 4500
Answer:
60
Step-by-step explanation:
A circle is 360 degrees
1/6 of 360
1/6 * 360 = 60
SO EASY 60 people = 10 minutes in line 240 people = 40 minutes in line

Answer: Choice D. 
</h3>
This is because we want to avoid having negative numbers under the square root. So we make the radicand to be 0 or larger.
The +1 at the end doesn't affect the domain.
