Answer:
<h2>2. Combining old and new observations.</h2>
Step-by-step explanation:
Through the passage, Nicholas Copernicus is introducing to the reader a new worlds, based on observations from the pass, and recent observations made by scientists. Basically, he's talking about a work where the reader is going to able to learn and be aware about the stars and planets movements in a way that no one could imagine before.
Copernicus specifically states that those observations are based on ancient and new data.
Therefore, the right answer is 2, because it's a combination of old and new observations.




First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .
Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .
So now our maths problem looks as follows :

Now turn the fraction you are dividing by over :

Now multiply the numerator of the first fraction times the numerator of the second fraction :
4
Perform the same operation with the denominators :
-4/14
So the result is :

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :


A rectangle would have two sides 12 meters long and two sides 9 meters wide.
The perimeter is the sum of the four sides.
12 + 12 + 9 + 9 = 42
The perimeter is 42 meters
The answer for 378 x 9 = 3402
