World war one lasted from august 4th 1914 until november 11th 1918 during this time an estimated 10 million lives were lost about how many people were dying per day

So first off you need to work out how many days there were in the war.
there are 365 days in a year, and 1916 was a leap year so it had 366 days.
You do 365 + 365 + 366 + 365 to work out how many days until august 4th 1918.
365 + 365 + 366 + 365 = 1461
now you need to calculate the days from august 4th until november 11th
you do (31 - 4) + 30 +31 + 11 = 99 days
total days = 99 + 1461 = 1560

to find out how many died per day you do 10000000/1560 = 6410

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
