Answer:

He can make it with Max's audio goods

44.575 miles < 45 miles

Step-by-step explanation:

The angle of the truck driver = 180 - (60 + 69) = 51°

By using sin Rule:

40/sin51 = Max's auto goods/sin60 = Jimmy's car supply/sin69

∴ Max's auto goods = 40(sin60)/sin51 = 44.575 miles

∴ Jimmy's car supply = 40sin(69)/sin51 = 48.052 miles

∵ The truck driver can travel another 45 miles

∴ He can make it with Max's audio goods because 44.575 < 45

A bin has 5 white balls and k black balls in it, where k is an unknown positive integer. A ball is drawn at random from the bin.
crimeas [40]

Answer:

Step-by-step explanation: The expected loss is 50 cents, we know that it is more likely to lose than win. It is therefore difficult to get-50, so the overall difference between the two possibilities is 2, 50/200=1/4, and the probability to win is 1/4, and the probability to lose is 3/4. Since (1/4)*3=3/4, the number of black balls is 3 times the number of white balls, so k=15.
