Door for the small cabinet are 11.5 inches long. door for the large cabinet are 2.3 times as long as the doors for the small cabinets. how many large doors can be cut from a board that is 10 feet long?

So if you take the small cabinet door length which is 11.5 inches long and multiply by a factor of 2.3 you get the total length of the large cabinet doors, which is 26.45 inches. So you're asked how many times will 26.45 inches go into 10 feet or 120 inches. 120 divided by 26.45 is about 4.5. So 4 large doors can be cut from a 10 foot long board.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
