2 answers:
Answer:
t = 23 seconds
Explanation:
It is given that, you roll a bowling ball down the lane and it takes 23 seconds to reach the pins. The ball moves under the action of gravity. The value of acceleration due to gravity on the surface of Earth is
The total time taken by the ball to move is equal to the time taken by th bowling ball down the lane.
So, total time it takes the ball to move is 23 seconds.

Answer:
It would take approximately 289 hours for the population to double
Explanation:
Recall the expression for the continuous exponential growth of a population:
where N(t) measures the number of individuals, No is the original population, "k" is the percent rate of growth, and "t" is the time elapsed.
In our case, we don't know No (original population, but know that we want it to double in a certain elapsed "t". We also have in mind that the percent rate "k" would be expressed in mathematical form as: 0.0024 (mathematical form of the given percent growth rate).
So we need to solve for "t" in the following equation:
Which can be rounded to about 289 hours
