The storage shed shape of a half-cylinder of radius r and length l.

the shed is filled with sawdust whose density (mass/unit volume) at any point is proportional to the distance of that point from the floor. the constant of proportionality is k. calculate the total mass of sawdust in the shed.

Let w=23 . what is the value of w + 45 ?

Many newspapers carry a certain puzzle in which the reader must unscramble letters to form words. how many ways can the letters of emdangl be arranged? identify the correct unscrambling, then determine the probability of getting that result by randomly selecting one arrangement of the given letters.
