Answer:
490.0...
Step-by-step explanation:
4.9 x 10^2
(squared)
4.9 x 10 x 10

About 3 gallons of blue paint will be needed because if you add 175+175 it equals 350 and then add another 175 it equals 525.
We have been given that the upstream speed is 
and the down stream speed is 
.
Let the fisherman traveled a distance of x miles.
The total time of the trip is 6 hours.
Relations between speed (s), time (t) and distance (d) is 
Hence, 
Time upstream + time downstream = 6
lcm = 10
=> 
Cross multiplying, 
x = 20 miles .. Answer.
Answer:
The next number would be 256
Keep Change Flip!!!
Keep: the first fraction 5 or 5/1
