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:
t = d/r
Step-by-step explanation:
Given the equation, d = rt for <em>t</em><em>:</em>
Switch sides:
rt = d
Divide both sides by r to isolate<em> t</em>:<em> </em>
t = d/r
I'm not too sure if this a a question for school but i think it really depends on what Sammy wanna wear.

If you mean like a method to solve it fast here I have 1 solution I usually use;
3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.
=8.1
