Lea and marie are washing all the windows in their house. it would take lea 80 minutes to wash the windows by herself, and it would take marie 60 minutes to wash them by herself. lea creates a table so she can find out how long it will take to wash the windows if they work together. what is the missing value in the table that represents the rate for marie?

The answer to your question is 1/60t just took the test

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

won't that be plagrisim thought?
