Let x=0.166666...-----------(1equation)
Multiplying by 10 in both sides
10x=1.66666...-------------(2equation)
Multiplying by 10 in both sides
100x=16.6666...----------(3equation)
Subtracting 2equation from 3equation
100x-10x=16.666..-1.666..
90x=15
x=15/90
0.16666....=15/90
<span>120 - 36 is 84 just as 12(10 - 3) = 12 x 7 = 84.</span>
Answer:
we will divide the hectare of land bt 6to get the size of each property
90.18÷6 = 15.03
V=LWH
SA=2(LW+LH+WH)
V=240
first check that they are 240 volume
multiply numbers they should equal 240
the first one (A) can be eliminated since the dimentions are the same and therefor the surface areas are the same
2nd one check so far
3rd one (C) 6*4*15=360 which is wrong so eliminate this one
4th (d) 12*6*5=360 which is not 240 so eliminate
answer is B
