What are the approximate solutions of 2x^2-x+10=0? f) -2,2.5 g) -1.97,2.47 h)-2.5,2 i) no solution. me . : *

To solve this problem, Uuse the quadratic equation:  
(-b +/- sqrt(b^2 - 4ac))/2a, 
 where 
 a = 2
 b = -1
 c = 10 
 Solve: 
 (1 +/- sqrt(1 + 4*2*10))/4 
 (1 +/- 9)/4 
 The two solutions are  
 10/4 = 2.5
 (1-9)/4 = -2. The correct answer is f.

2/3 gallon

Step-by-step explanation:

you take 1/3, which is the amount you are looking for to fill the rest of the container, then you multiply that times 1/2.  this equals 1/6 of a gallon. then you add that to 1/2 a gallon to find out the total of all the water it takes to fill the bin.  1/2+1/6=3/6+1/6=4/6 or 2/3 gallon simplified. 

HOPE THIS IS CORRECT :)
