An angle passes through the point (-7,-5). what is the compass heading of this angle?
(round to the nearest hundredth).

215.53

Step-by-step explanation:

Take the inverse tangent of the plot point:

tan^-1 (-5/-7) = 35.5377

Add the answer to 180 (because a compass heading is found from going clockwise from the North Point) to get the final

215.53 degrees

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:
