One way is to estimate
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
the number 61 is between 49 and 64 therefor the square root of 61is between the intigers 7 and 8 or -7 and -8
12.25 inches. the equation to find that would be 3.5 squared or 3.5 times 3.5
Let the number of years after 2001 be x, then
1280000 + 19500x = 1700000
19500x = 1700000 - 1280000 = 420,000
x = 420000/19500 = 22 years.
x = 22 years.
55.04 is 256% of 21.5
Hope it helps and hope its right...---
4*200+4*70+4*5, or you can just use a calculator.
