Question

Tracy is observing the altitude of various birds as they descend in the air.The change in altitude is shown in the table. Select all of the birds that descended less than 15 feet.

Answer 1

The birds are Hawk and Falcon respectively.

Step-by-step explanation:

Descending is represented by a negative

A bird descending 15 feet = - 15feet

We are to pick birds that descended less than 15 feet. This means numbers less than -15 would be considered.

On a number line: the bigger the negative number, the lesser the value of the number.

-13 feet > -15feet

-21 feet < -15feet

-11 feet > -15feet

-17 feet < -15feet

-14 feet > -15feet

The altitude less than -15 feet are -21 feet and -17 feet

The birds are Hawk and Falcon respectively.
