To convert 23,000 seconds into hours which two ratios could you multiply by ?

You can get to this answer doing it like this:
if 1 hour = 3600 seconds 
Then
23 000 seconds = 6 hours 23 minutes 20 seconds
Or
multiply by 1/3600
or 
1 minute = 60 seconds 
1 hours = 60 minutes 

1 minute 1 hour 
23000 seconds x x = 
60 seconds . 60 minutes 

 
23000 x (1/60) x (1/60)
I hope all of this info can help you

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
