How to convert 3mm into cm

0.3 cm

Step-by-step explanation:

1 cm = 10 mm

1) Using proportion:

1 cm 10 mm

x cm  3 mm

x = 1 cm * 3 mm/10 mm = 0.3 cm

2) 3 mm * 1cm/10mm = 0.3 cm

3mm = 0.3 cm

Step-by-step explanation:

1 cm = 10 mm

3mm = 3/10 = 0.3cm

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:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
