Tomas makes balloon sculptures at a circus. in 90 minutes he makes 150 balloons to make 30 identical balloon sculptures how many minute does it take to make one balloon sculpture

The answer to your question is 3.

Alright! Starting out, we would first put the ratio 
90:150:30, then we simplify it, which gets us
30:50:1, so 30 minutes for 1 balloon sculpture.

Hope this helps and have a nice day:)

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
