Answer:
20 + 1 + 0.9 + 0.07
Step-by-step explanation:
Given the number 21.97 ;
To wite in expanded form:
Tens ___ Unit ____ tenth ____ hundredth
2_______ 1 _______ 9_________ 7
2 = 20
1 = 1
9 = 0.9
7 = 0.07
Hence,
20 + 1 + 0.9 + 0.07
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>
