What is the ratio of Grade 7 to Grade 8 students on Team A. * On Team A, of the students are in Grade 7, the rest are in Grade 8.
On Team B, of the students are in Grade 8, the rest are in Grade 7.

I can't answer this and I don't think anyone can, there is not enough information. (yet again I'm 12 so I can't say much)

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.

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
