The circumference of circle p is 800 mm, the circumference of circle q is 200 cm, and the circumference of circle r is 4 m. what is the sum of the distances around each circle? media53aa96a6ceba9.jpg a. 24.2 m b. 7.5 m c. 6.8 m d. 31.4 m

circle P has a circumference of 800mm which is equal to 80cm

circle Q is 200cm

circle R is 4m which is equal to 400cm

You will get the sum of the distances by placing the figures under one measurement that is meters

And so add the figures in cm(200+400+80) and get 680

Then convert this to meters and get 6.8m

Hence your answer is C

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:
