Chad and his two friends are picking blueberries at a local farm. chad picked 2 1/2 pounds of blueberries, and one of his friends picked 1 3/8 pounds. if they ended up with a total of 5 1/4 pounds, how many pounds did chad's other friend pick? express your answer as a mixed number.

Number of pounds the other friend picked  =

5 1/4 - 1 3/8 - 2 1/2

= 21/4 - 11/8 - 5/2  The LCD of 2, 4 and 8 is 8 so we have:-

=  42/8 - 11/8 - 20/ 8

=  11/8

= 1 3/8 pounds Answer

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

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.
