Change 50% to a decimal, then a fraction. 0.05, 1/20 0.5, 1/2 0.05, 1/2 0.5, 1/20

0.5 and .

Step-by-step explanation:

Given : 50%.

To find : change 50% to a decimal, then a fraction.

Solution : We have given Number 50 %

In decimal form

We can convert percentage in to decimal by dividing by 100.

50% = .

0.5

50% = 0.5.

In fraction form :

.

On dividing both number by 50

.

Therefore, 0.5 and .

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.
