<span>Find
which of the following cereal is best buy
a. 28 oz for 4.29 dollars
=> 28 / 4.29
=> each 1 oz of cereal cost 6.5
dollars
b. 32 for 4.59 dollars
=> 32 / 4.59
=> 6.97 or 7.00 dollars
=> each 1oz of cereal cost 7.00 dollars
c. 36 oz for 4.79 dollars
=> 36 / 4.79
=> 7.4 dollars
=> each 1oz of cereal costs 7.4
d. 24 for 3.59 dollars
=> 24 / 3.59
=> 6.7 dollars
=> each 1 oz of cereal cost 6.7 dollars
Thus, the best buy cereals is d. 24oz for 3.59 dollars</span><span>

So use pythagorean theorem
a^2+b^2=c^2
a=base
b=height
c=legnth of ladder
a=2
b=c-0.5
subsitute
2^2+(c-0.5)^2=c^2
4+c^2-c+0.25=c^2
add like terms
c^2-c+4.25=c^2
subtract c^2 from both sides
-c+4.25=0
add c to both sides
4.25=c
the legnth of the ladder is 4.25 m
28.95 is 14.7 greater than 14.25
