Mr. Becker loves to birdwatch. One day on his many bird-outings, he notices a gray- throated robin in the tops of a tree. Having been to this tree before, he knows that the
tree is 53 feet tall. If the angle of elevation between Mr. Becker and the top of tree is 42
degrees, how far away is Mr. Becker from the base of the tree? ROUND YOUR ANSWER
TO ONE DECIMAL PLACE.

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:

$9.41
