The shortest possible height of tower is 24 cm.
Tim used 4 blue blocks and his brother used 3 green blocks.
Step-by-step explanation:
Given, 
Height of blue block = 6 cm 
Height of green block = 8 cm 
We will take least common multiple to find the shortest possible height.
6 = 2*3
8 = 2*2*2
LCM = 2*2*2*3 = 24 cm
The shortest possible height of tower is 24 cm.
Number of blue blocks used = 
Number of green blocks used = 
Tim used 4 blue blocks and his brother used 3 green blocks.

Answer:
0.4kg, 1.4kg and 1.8kg
Step-by-step explanation:
 Given parameters: 
          Mass of alloy = 3.6kg 
          Ratio of elements in the alloy = 2:7:9 
Unknown: 
Mass of each element in the alloy = ? 
Solution: 
To find the mass of each element in the alloy, first find the sum of the ratio;
               2+7+9 = 18 
Mass of nickel  =  x 3.6 = 0.4kg
 x 3.6 = 0.4kg
Mass of zinc =  x 3.6 = 1.4kg
 x 3.6 = 1.4kg 
Mass of copper =  x 3.6 = 1.8kg
 x 3.6 = 1.8kg 
The mass of each metal is 0.4kg, 1.4kg and 1.8kg
