Four penguins would satisfy a polar bear's appetite for 12 hours. A polar bear has a
julsineya [31]

Answer:

0.04%

Step-by-step explanation:

If there are 1000 penguins per square miles, <em>the total number of penguins in a  10 square miles will be 1000*10 = 10,000 penguins/10square miles</em>

Since a polar bear has a territory of 10 square miles, and<em> can only eat four penguins within the 10square miles;</em>

<em />

Percentage of penguins that the polar bear can eat will be expressed as;

number of penguin eaten per 10square miles/total number of penguin per 10square miles * 100

Percentage of penguins that the polar bear can eat = 4/10,000 * 100%

Percentage of penguins that the polar bear can eat = 4/100%

<em>Hence, the percentage of penguins that the polar bear can eat in the 10 square miles is 0.04%</em>
