Joe went to the hobby shop and bought 2 sport cars at %8.95 each and some paints. if he spent a total of %23.65,what was the coast of the paint? ?

I'm assuming that % means $:

8.95*2 = 17.9

23.65 - 17.9 =  5.74

The cost of the paint was $5.74

his chances of getting a coin of higher value is 4/19

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.
