So her friend runs 3/5 the distance of Nicole's, and that happens to be 3/8 of a mile.
now, a whole will be 5/5, or 1 whole, and that's how much Nicole runs.
we know that 3/5 of Nicole's distance is 3/8 of a mile, what is 5/5 or 1 whole?
1. Check the picture attached. Consider the half of the 8-sided die, that is the pyramid ABCDE:
2. The perimeter of the base is 6, so each side of the base is 6/4=3/2
3. The distance between the tallest points is 2 cm, si the height of Pyramid ABCDE is 1 cm.
4. Consider the right triangle EOM in the figure:
EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is
(cm)
5. So side EBC has area
6. The total area is 8*Area(EBC)=
