Alength of rope is stretched between the top edge of a building and a stake in the ground. the head of the stake is at ground level. the rope also touches a tree that is growing halfway between the stake and building. if the tree is 16 feet tall, how tall is the building? 32 8 24 16

You can see that the tree is at the half way point of the rope.The double lines on each side of the tree means that both sides are equal. The problem states the tree is 16 feet tall so you would multiply the tree's height by two and get 32 feet!

I hope this helps <3

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
