Acity has a population of 320,000 people. suppose that each year the population grows by 3.5%. what will the population be after 12 years?
use the calculator provided and round your answer to the nearest whole number.

First find what 3.5% is of 320,000 is. That is 11,200. If it grows by 3.5% each year for twelve years, then it is growing by 11,200 * 12. Over 12 years the growth is 134,400. Total population would then be 320,000 + 134,000 so 454,400.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
