volunteers a, b, and c volunteered offered to stuff 838 envelopes with newsletters for a certain reelection campaign. volunteer a could assemble 170 per hour, volunteer b, 117 per hour, and volunteer c, 142 per hour. they worked a total of 6 hours. the sum of the number of hours that volunteers b and c spent was twice what volunteer a spent. how long did each of them work?

step-by-step explanation:

answer: just subtact the units and then add the non negative : happy to

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.

answer: i ! the answer is   9000 seconds, also d

hope i
