.6 because it is very low compared to the other numbers
A percent is just that number over hundred, so if it was 20%, it would be 20/100. That could be termed to differentiate the quantity amounts

A circle has an area of 40 square meters. Which answer is closest to the measure of its diameter?
Answer: Choice B 
=============================================
Explanation:
The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.
The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5
Put another way: x is either 4.5 or smaller
We write that as
which is read out as "x is less than or equal to 4.5"
Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"
All together we end up with the answer
which translates to "x such that x is less than or equal to 4.5"
Answer: 
Step-by-step explanation:
Let be "x" the amount of miles light will travel in 4,200,000 seconds.
Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:
According to the exercise, light travels
miles in 1 second.
Therefore, based on this data, you can set up the following proportion:

And finally, you must solve for "x" in order to find its value.
(Remember the Product of powers property:
)
Then:
