I would round it to 81.1. If the .039 was 5 or over, I probably would have gone to 81.2.
Hope I helped! Have a nice day!
First, all the heights have to be converted to similar units, say feet.
Therefore,
Building= 20 feet
Tree = 252*0.083333 = 21 feet
Flagpole = 6*3 = 18 feet
The tallest of the three is the tree and thus should cast the longest shadow. However, it should be noted that at exactly noon when the sun is overhead, all the three will have equal length of shadow (that is, 0 feet long).
The bisector should be (5,4)
<em>x</em> = liters of 1% solution
<em>y</em> = liters of 5% solution
<em />
<em>x</em> + <em>y</em> = 16
0.01<em>x</em> + 0.05<em>y</em> = 0.04*16 = 0.64
<em />
<em>y</em> = 16 - <em>x</em>
<em />
0.01<em>x</em> + 0.05(16 - <em>x</em>) = 0.64
0.01<em>x</em> + 0.8 - 0.05<em>x</em> = 0.64
0.16 = 0.04<em>x</em>
<em>x</em> = 4
<em>y</em> = 12
