Final answer:
The height between the table and the ceiling is 8 feet.
Step-by-step explanation:
To find the height between the table and the ceiling, we can use the given ratio of 1:4 for the chandelier's height to the distance from the table to the bottom of the chandelier. Let's say the height of the chandelier is 'x', then the distance from the table to the bottom of the chandelier would be 4 times 'x'.
Given that the height of the dining room table is 2.5 feet, and the height from the floor to ceiling is 12.5 feet, we can set up the following equation:
2.5 + 4x + x = 12.5
Simplifying the equation, we get:
5x + 2.5 = 12.5
5x = 10
x = 2
Therefore, the height between the table and the ceiling is 4 times 'x', which is 8 feet.
