The table shows how long it took melinda to do her math homework each day over four days. table) monday: 3/4, tuesday: 5/6, wednesday: 2/3, thursday: 1/2 what is the ratio of the time it took melinda to do her math homework on wednesday to the time it took her to do it on tuesday. me, i struggle with this topic in school.

4/5

The question is asking you to find the ratio of Wednesday's time (2/3) to Tuesday's time (5/6). To do that, you divide the fractions:

... Wednesday / Tuesday = (2/3) / (5/6)

There are a couple of different methods you can use to divide fractions.

1. Invert the denominator and multiply.

When we invert 5/6, it becomes 6/5. So our division problem is now a multiplication problem:

... (2/3) × (6/5) = (2×6)/(3×5) = 12/15

This result can be reduced by removing a factor of 3 from numerator and denominator:

... Wednesday/Tuesday = 4/5

___

2. Make both fractions have the same denominator, then drop the denominators.

The denominators of the fractions in our ratio are 3 and 6. If we multiply 3 by 2, it becomes 6, so we can rewrite the numerator fraction as ...

... 2/3 = (2/3)×(2/2) = 4/6

Now, it has a denominator of 6 and our division problem is

... (2/3) / (5/6) = (4/6) / (5/6)

Dropping the (same) denominators gives ...

... Wednesday/Tuesday = 4/5

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.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
