The height of the pole is 12.5 feet.
<h3>What is Unitary method?</h3>
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cindy's shadow is 5 feet.
length of the shadow of the pole at the same time, she finds it to be 12.5 feet.
So,
12.5/5=x/5,
62.5=5x
x= 12.5 feet.
Hence, the height of the pole is 12.5 feet.

Using the order of operations, we will have to do 24/8 first, which will result in the answer of 3. Then, we just work from left to right.
3-3+42
0+42
42 <-- will be your final answer.
Half-Life = ln (.5) / k
Half-Life = .693147 / .00011

For a radioactive substance to decay to 25%, it has to go through 2 halflives.
2 * 6,301 = 12,602 years
approximately 12,600 years
