Biology

The earth’s climate is changing because of human impact. For example, because of our extensive use of cars and fossil fuels, the carbon dioxide builds up in the atmosphere. When that happens, it creates a “blanket” trapping in heat and that makes the temperature rises.

Flock X Flock Y Flock Z Total Pieces of Food Eaten (from previous page) 123 99 78 Food Percentage*  %  %  % Simulated Number of
HACTEHA [7]

Answer:

Flock X  - 41 % - 12

Flock Y - 33% -  10

Flock Z - 26% -  8

Explanation:

All you really need to do is follow the instructions.

Here is the information given:

               Total pieces of

                Food Eaten            Percentage(%)                             Number of birds      

Flock X              123             123/300 = 0.41 x 100% = 41%          0.41 x 30 = 12

Flock Y               99              99/300 = 0.33 x 100% = 33%        0.33 x 30 = 10

<u>Flock Z               78              78/300 = 0.26 x 100% = 26%        0.26 x 30 = 8   </u>

Total                 300                                                    100%                           30

In the percentage portion you need to multiply it by 100% if you want to get the percentage in percent. By multiplying it by the total number of birds, you will be able to get the number of birds in each flock.
