A glacier advanced 12 feet during a 16-day period in January. The same glacier advanced 18 feet during a 24-day period in February. Are the ratios of feet to days proportional for these two periods of time?

Drag and drop to correctly complete the statement.

3 feet : 4 days  

Explanation:

Ratio of feet to days in January:   Ratio of feet to days in February:

        12 feet to 16 days                            18 feet to 24 days

Now let us reduce both to the lowest terms and compare;

 Divide by 4                                              Divide by 6

    3 feet : 4 days                                     3 feet : 4 days  

For both time periods, the ratio of feet to days are the same.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
