Dierdra saw a pole that was supported by a wire as shown. She calculated that the wire was the square root of 1,625 feet long. Between which two numbers is the value of square root of 1,625 located?

7. thatgirlisheres

does anyone know what it is

8. experimentX

yes ... it is 1.3333333333333333333333333............. can you write it down as ratio of two numbers?

9. thatgirlisheres

ok thanks

10. experimentX

when you have that bar ... over some numbers, then it means that number keeps repeating. eg |dw:1361550634265:dw|

11. experimentX

such repeating numbers are rational numbers ... just multiply it by 100 or (in your case 10) and subtract from the original number.

If I was on earlier then I would have gave the answer, but the others already did... v_v

18. experimentX

find two perfect squares below and above 1625 |dw:1361551481511:dw|
