Question

1. how long does it take, in seconds, for the ball to drop?

$(12^2 + 6^2) \div 3$

Explanation:

Step1: Calculate the squares

First, we calculate the squares of 12 and 6.
\(12^2 = 144\) and \(6^2 = 36\).

Step2: Add the results

Then we add these two results together.
\(144 + 36 = 180\).

Step3: Divide by 3

Finally, we divide the sum by 3.
\(180\div3 = 60\).

Answer:

60
