Convert 17.47° to degrees, minutes, and seconds..
never [62]
For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,

0.47 degrees * 60 minutes per degree= 28.2 minutes

Now you have 17 degrees 28.2 minutes but you can replace fractions of a minute with seconds
 
0.2 minutes * 60 seconds per minute= 12 seconds

So the answer for 17.47º is equal to 17º 28' 12".

I hope this helps.

Katena32 [7]

Answer:

The answer is 28/9

And we are expected to find f(6), that is substitute the value of x with 6

Step two:

f(6)= 2/3(6)+3\\\\f(6)=2/18+3\\\\f(6)=1/9+3\\\\f(6)=1+27/9\\\\f(6)= 28/9
