There are 48 students attending band camp, 18 girls and 30 boys. what is the
ratio of girls to boys at band camp?
a. 5: 3
b. 3: 2. c. 3: 5

18 : 30

Divide both sides by 2

9 : 15

Divide both sides by 3

3 : 5

C. 3 : 5

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

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.
