Q12: At Burns High School, 35 of the students are females. Of the female students, 13 of them play volleyball. What fraction of the students in Burns High School are girls that play volleyball? of the students

Step-by-step explanation:

we don't know the numerator. so we should find the scale factor.

to find scale factor divide the 100 by 35

we get the scale factor as 2.86

now multiply the previous fraction by this scale factor

13 out of 35 girls play the volleyball in burns high school or we can put it as 37.18 % of the girls at Burns Highschool

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

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.
