Answer:
It'll take a bucket loads of
to empty world's ocean
Step-by-step explanation:
Given



To get the number of bucket loads, we simply divide the size of the ocean by the size of the bucket;


Expand the numerator

Recall that 
So, the expression becomes

Simplify the numerator using laws of indices


Expand the denominator


Split fraction


Simplify fraction using laws of indices



Hence, it'll take a bucket loads of
to empty world's ocean
<u>Answer:</u>
The correct answer option is D. 120°, 240°.
<u>Step-by-step explanation:</u>
We are given the information about x that
.
We know that [tex]cos x=-\frac{1}{2}[/tex ] is actually the ratio of adjacent side to the hypotenuse. It means that here, adjacent is -1 and hypotenuse is 2.
A negative cosine tells us that the angle is either in Quadrant II or Quadrant III.
So if it is in 2nd quadrant, then x = 120° and if its in 3rd quadrant then x = 240°.
