At 3:00 PM a man 144 cm tall casts a shadow 146 cm long. At the same time, a tall building nearby casts a shadow 171 m long. How tall is the building?
Give your answer in meters. (You may need the fact that 100 cm = 1 m.)
Cant you use a ratio here?
h1/s1=h2/s2 solve for h2
a rectangular lot is bounded at the back by a river . No fence is needed along the river and three is to be a 24-ft. opening in front. if the fence along the front costs $1.50 per ft.,along the sides $1 per ft. find the dimensions of the largest lot which can be thus fenced in for $300
