To be able to quickly solve this, we can temporarily make 5.47 into 547
Now, we can divide 547 by 12.

Now, we can round up from 45.5 to get 46.
However, we originally moved our decimal 2 places over, so now we must move it 2 places again.
46 ⇒ 0.46
The correct answer is $0.46
You would pay $33 for the bracelet
One way it's useful is in the application of phasors in physics. Phasors require you to add up vectors of two different angles, so the cosine angle addition formula can be used if you already know the cosine and sine of the original vector angles.
Answer: -2.1, -0.5, 5/100, 0.5, √5
Step-by-step explanation:
Start with the negative numbers. Take the absolute value - the ones with the largest absolute value are the farthest from 0, so they are the smallest numbers.
-2.1, -0.5
Then, convert the numbers not in decimals to decimals.
5/100 = 0.05
√5 is about 2.3.
5/100, 0.5, √5
