Atree casts a shadow 7.5 long. awomen 5 ft. tall casts a shadow 3 ft. long. the triangle shown for the tree and its shadow is similar to the triangle shown for the women and her shadow. how tall is the tree?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
