Amail distribution center processes as many as 180,000 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 1250 pieces per load the loading equipment is able to handle as many as 150 loads per day. let x be the number of loads by land, y the number of loads by air.

i know its b or d but which one is it?

a)1250x+2000y> =18 x+y> =150
b) 2000x+1250y< =18 x+y< =150
c) 1250x+2000y< =18 x+y< =150
d) 2000x+1250y> =18 x+y> =150

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
