Equation 1: L+D=(8x60) L+D=480 D=480-L Equation 2: D=L+((4x60)+40) D=L+(280) 480-L=L+280 -280 -280 200-L=L +L +L 2000=2L ----- ------ 2 2 100=L D=480-L D=480-100 D=380 it takes L 100 minutes and D 380 minutes it takes L 1hr 40min and D 6 hr 20 min.
They can also be expressed C D and L and they represent 100 500 and 50 respectively
Neither X, L, nor D, are 5 in roman numerals. X is 10, L is 50, and D is 500. 5 is always represented as a V in roman numerals.
L=50 c=100 d=500 m=1000
If d is the diagonal and h is the height Let, l=length of rectangle we have By pythagrous theorem d square= l square + h square therefore l square= d square - h square
