You compare the sizes of two MP3 players. The old model is 34 inch thick. The new model is 25 inch thick. How much thinner is the new model than the old model?

 or 0.35

Step-by-step explanation:

"Thinner" and "than" suggest subtraction. So find the difference:

Find the least common denominator to subtract

4, 8, 12, 16, 20

5, 10, 15, 20

20 is the lowest common denominator. Multiply the fractions until they have the same denominator of 20. Don't forget to do the same with the numerator:

Simplify

Now subtract, but don't change the denominator:

The newer model is 0.35 inches thinner than the old model.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

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.
