icang [17]

Answer:

Step-by-step explanation:

The water has to be 100% - 60% = 40%

100% represents both water alcohol (I think that's what you meant).

40% of 250 = 40/100 * 250 = 10000/100 = 100 mL

So 100 mL = water

150 mL = alcohol.

if alpha and beta are the zeroes of the polynomial f(x) = 6x² + x - 2, find the value of 1/alpha + 1/beta - alphabeta​
finlep [7]

Answer:

let alpha be x and beta be y

Step-by-step explanation:

x+y= -b/a

x+y=-1/6

and xy= c/a

xy= -1/3

according to question

1/x+1/y -xy =(x+y)/xy-xy

(-1/6)/(-1/3)-(-1/3)

1/2+1/3

the answer is 5/6
