Kira new chatted online with all her friends for 2/3 of a hour on Saturday and 1/4 of an hour on Sunday. She chatted with Penelope for 1/8 of the time. Which fraction of an hour did Koran apes chatting with Penelope?

of an hour.

Step-by-step explanation:

Given:

Koran new chatted online with all her friends on Saturday for  = 2/3 of a hour.

Koran new chatted online with all her friends on Sunday for  = 1/4 of an hour.

She chatted with Penelope for = 1/8 of the total time.

Question asked:

Which fraction of an hour did Koran apes chatting with Penelope ?

Solution:

Koran new chatted online with all her friends on Saturday for = of an hour

Koran new chatted online with all her friends on Sunday for = of an hour

Total time of chatting =

                                    =       ( By taking LCM of 3 and 4 we get 12 )

                                    = of an hour

Now, She chatted with Penelope for = of an hour

Therefore, Koran chat of an hour with Penelope.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

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.
