Let the person's arm length be = x
Condition is : sleeve lengths available from 20 inches to 40 inches and the length of the sleeves should be about 1.2 times a person's arm length.
So, the inequality equation becomes:
This gives x=
or 
or x=
=33.33 or 
Hence, the shop does not provide tuxedos to people with arm length less than 16.66 inches and greater than 33.33 inches.
Since the
density =mass /volume
if volume is constant we can rewrite the density equation as
volume=mass / density
since volume is just a constant
c*density=mass
where c is some constant that denotes the constant volume
mass and density will be proportional to each other or in other words will be have exactly in the same way if one increase the other will increase if one decreases the other will decrease if one stays constant the other will stay constant
only the fourth choice satisfies the proportionality condition so it must be the correct choice
Step-by-step explanation:
the second one, they are in proportion to each other in respect to the interfere values
