This past winter, 643 flamingos migrated to Gordon Lake. A researcher states that the number of flamingos migrating to the lake
is decreasing by 12 birds every year. Which of the following represents the number of flamingos, n, that will migrate to the lake t winters from last winter if the researcher’s trend continues? A. t = 643 - 12n B. n = 643 - 12t C. t = 12 - 643n D. n = 12 - 643t
Okay so the circumference of a circle is pi×the diameter or 2×radius× pi. In this case we are given the radius so C=2×20×3.14 C=40×3.14 C=125.60 The circumference is 125.60cm
