Amall distribution center processes as many as 150,000 pieces of mail each day. the mail is sent via ground and air. each land carrier takes 2000 pieces per load and each air carrier 1500 pieces per load. the loading equipment is able to handle as many as 200 loads per day.
let x be the number of loads by land carriers and y the number of loads by air carriers. which system of inequalities represents the situation?
options:
1500x+2000y> =150,000 x+y> =200
2000x+1500y> =150,000 x+y> =200
2000x+1500y< =150,000 x+y< =200
1500x+2000y< =150,000 x+y< =200

An eight-sided die, which may or may not be a fair die, has four colors on it; you have been tossing the die for an hour and have recorded the color rolled for each toss. what is the probability you will roll a brown on your next toss of the die? express your answer as a simplified fraction or a decimal rounded to four decimal places.
