A square field measuring 100.0 m by 100.0 m has an area of 1.00 hectare. an acre has an area of 43,600 ft2. if a lot has an area
liq [111]
The problem given above is simply a conversion problem. <span>We are asked to convert from units of acres to units hectares. To do this, we need a conversion factor which would relate the different units involved. We either multiply or divide this certain value to the original measurement depending on what is asked. For this case, we use the given values to determine the relation. We do as follows:

1 hectare = 100 m x 100 m = 10000 m^2
1 hectare = 10000 m^2 ( 1 ft / 0.3048 m )^2 = 107639.10 ft^2
107639.10 ft^2 ( 1 acre / 43600 ft^2 ) = 2.47 acre

Thus, 1 hectare = 2.47 acres

12.0 acres ( 1 hectare / 2.47 acres ) = 4.86 hectares

If im was born on june 9th of 1993 from 2015 she still alive how old is she now?
Vladimir79 [104]
If you're born on June 9th in 1993, on June 9th in 2015 you would have your 22nd birthday (2015-1993=22).

So you're 22 years old, and, as of today, 17 days tool (22 years 17 days).

3(2x-14) x=15-(-9x-5) solution?
nikklg [1K]

so what you have to do is multiply 3 and 2 and 3 and -14 which ends up being 6x-42x=, then do 15 times -9 and you then do 15 times -5 and that becomes -135x - (-7) then you show it like this= 6x-42x=135x-(-7) the solution would be 36x=-135 divide 36 each side and you get x= 2.28
