Tristy scored 95% in her maths exam .If the exam was out of 120 ,how many marks did she score?

X = 114

Step-by-step explanation:

Set the problem up like this: x/120 = .95 (same as 95/100).

solve for x.  You multiply both sides by 120 because multiplication undoes division.  You are left with x = 114.

answer: it is d

step-by-step explanation:

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.
