150% of a is equal to $120 and 120% of b is equal to $90

a=80 + b=75

Step-by-step explanation:

150% of A is equal to $120 and 120% of B is equal to $90

150%×A=$120 + 120%×B=$90

150/100×A=$120 + 120/100×B=$90

Cross multiply at each equal sign

150A×1=$120×100 + 120B×1=$90×100

150a=$12000 + 120b=9000

divide by 150 at A side and 120 at B side

150a/150=$12000/150 + 120b/120=9000/120

a=80 + b=75

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.

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!
