The circumference of circle A is 400 meters. The circumference of circle B is 800 meters. What is the relationship
between the radius of circle A and the radius of circle B? Justify your answer.

Circle B is 2 times bigger then circle A

Step-by-step explanation:

This is because

Circle A

400/pi= about 127.3

Circle B

800/pi= about 254.6

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:
