An adventure company wants to run a zip line from the top of one building that is 95 feet tall to the top of another building that is 55 feet tall. the two buildings are 30 feet apart. estimate the length (in feet) of the zip line. round your answer to the nearest tenth .

The difference of the length between the 2 buildings
D=L1-L2
D=95-55
D=40 feet
we use Pythagoras formula
D^2+X^2=Z^2
X=distance between buildings
Z=length of the zip line
Z=50 feet

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
