Answer: 48-39= 9
9 inches
Step-by-step explanation:
It should take 45 minutes. 18/12=1.5
30 times 1.5 is 45
The ratio between the amount of blue and yellow paint needed to make green paint is 2: 3.
That is, for every 2 liters of blue paint you need 3 liters of yellow paint.
In the same way, for every 4 liters of blue paint, 6 liters of yellow paint are needed.
Then, to continue filling the table, you must consecutively sum 2 liters of blue paint and 3 liters of yellow paint in the corresponding column. This will increase the amount of green paint by a factor of 5 liters.
The same procedure is followed until 45 liters are summed to the green paint column. Then, the data in that row will indicate how much blue and yellow paint is needed:
18 liters of blue paint
27 liters of yellow paint
To verify the result divided 18/27
The result should be 0.6667 = 2/3, which is the ratio sought
