5-10                              8

10-15                            9

15-20                          15

20-25                          10

25-30                           8

30-35                           6

total                           56

Average =

[5+10]/2*8+[10+15]/2*9+[15+20]/2*15+[20+25]/2*10+[25+30]/2*8+[30+35]/2*6

The hypotenuse of a right triangle is √18 units. what are the lengths of the legs of the triangle? How many different answers ca
storchak [24]
Since a right triangle has special rules to it such that the hypotenuse squared equals the sum of the squares of the other 2 sides. In other words, if the hypotenuse = c, and the 2 smaller sides are a and b, then:
{c}^{2}  =  {a}^{2}  +  {b}^{2}
Solving for c (hypotenuse), we get:
\sqrt{({c}^{2})} =   \sqrt{({a}^{2}+{b}^{2} )} \\ c =  \sqrt{({a}^{2}+{b}^{2} )}
Therefore c is the root of the square of the other sides. So by having root18, it's like saying:
\sqrt{18} =  \sqrt{({a}^{2}  +  {b}^{2} )}  \\ 18 = {a}^{2}  +  {b}^{2}
Getting rid of the square root, so sides a and b must have their squares total 18:
the only squares < 18 are: 16 (4×4), 9 (3×3), 4 (2×2), and 1 (1×1)
of those above added in any order of two of them, only 16+4
18 = 17 + 1 -  -  >  \sqrt{17}  \: and \: 1 \\ 18 = 16 + 2 -  -  >  \sqrt{16} \: and \:  \sqrt{2}  \\ ... \: 4 \: and \:  \sqrt{2}  \\ 18 = 15 + 3 -  -  >  \sqrt{15} \:  and \:  \sqrt{3}
18 = 14 + 4 -  -  >  \sqrt{14} \:  and \:  \sqrt{4}  \\ ... \sqrt{14} \: and \: 2  \\ 18 = 13 + 5 -  -  >  \sqrt{13} \: and \:  \sqrt{5}   \\ 18 = 12+ 6 -  -  >  \sqrt{12} \:  and \:  \sqrt{6}
18 = 11 + 7 -  -  >  \sqrt{11} \:  and \:  \sqrt{7}  \\ 18 = 10 + 8 -  -  >  \sqrt{10} \:  and \:  \sqrt{8}  \\ ... \sqrt{10} \:  and \: 2 \sqrt{2}  \\ 18 = 9 + 9 -  -  >  \sqrt{9}  = 3 \: and \: 3
