The box plots show theo's math scores and language arts scores.
about 50% of theo's scores are in which range for each subject?
a. 60 to 85 for math; 60 to 80 for language arts
b. 55 to 90 for math: 50 to 90 for language arts
c. 55 to 60 for math: 50 to 60 for language arts
d. 85 to 90 for math; 80 to 90 for language arts

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

3; 9 is 8 to -4

step-by-step explanation:

step-by-step explanation:

5389/6 = 898.1666667

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.
