Find the time between 12:20 and 23:0 the same day

FrozenT [24]

I'm guessing you are using military time.

Note, 23:00 is the same as 11:00 pm, and 12:20 is the same as 12:20 pm

Also note: 1 hour = 60 minutes

1) Change 1 hour inside 23:00 to minutes

23:00 = 22:60

Subtract

22:60 - 12:20 = 10:40

The time between 12:20 and 23:00 is 10 hours and 40 minutes

hope this helps

103^2-102^2=_____×(103-102)=_____<br>pls help me...this is in factorization

Ray Of Light [21]

103^2-102^2

The property that applies here is a^2-b^2 = (a+b)(a-b)

so the answer is 103^2-102^2=(102+103)*(103-102)= numerically it is 205( as 103+102 = 205 and 103-102 = 1.....so 205*1 = 205)

The thing is that usually the factorization ends at (102+103)(102-103) ......
