The sum of 3.0478 and 4.92 is 
, which have 5 significant digits.
<u>Step-by-step explanation:</u>
We have , 
and 
. The significant digits of a number are digits that includes all digits except:
- All leading zeros. For example, "013" has two significant figures: 1 and 3;
- Trailing zeros when they are merely placeholders to indicate the scale of the number and ,
- Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment supports.
Here and with significant digit rules 
. Now, Sum of both numbers = 
⇒Sum of both numbers = 
⇒Sum of both numbers =
∴ The sum of 3.0478 and 4.92 is , which have 5 significant digits.
Answer:
the greatest common factor is 50
Step-by-step explanation:
200 = 2 × 2 × 2 × 5 × 5 Find the prime factorization of 1650
1650 = 2 × 3 × 5 × 5 × 11 To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 5 × 5GCF = 50
5/15 x 3/15 = 1/3x 1/5 = 1/15
B is the answer.
