Answer:
x = 6
y = 24
z = there is no z?
Step-by-step explanation:
All angles of a polygon add up to 360 degrees
The 2 parellel lines on top and bottom mean that there are 2 right angles on the left side
3y + 18 = 90
3y = 72
y = 24
15x + 30 + 10x = 180
25x = 150
x = 6
The formula for geometric mean is nth root of the product of all terms. n denotes the number of data. Since you have only two points, 99 and 11, n = 2. The product of both terms is 99 × 11 = 1089. The square root of 1089 is 33. Thus, the answer is 33.
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>
Yes it is a rational number it can be expressed as a fraction
