The ratio of team leaders to players is 1:18. How many team leaders will be
needed for 72 players?

4

Step-by-step explanation:

if the ratio is 1:18 that means for every 18 players there will be 1 team leader. A simple way to find the answer to problems involving ratios is to simply plug in the numbers. In this case the ratio is 1:18, so first plug in the number you have by dividing the amount of players by the original ratio given, so 72/1 = 1. This makes 72:18, then divide 72/18 = 4.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
