A computer manufacturer shipped a total of 50 machines to its two warehouses, one in west and one in east. It cost 20$ per machi ne to ship to west and 25$ per machine to ship to east. The manufacturer spent a total of 1090 in shipping. How many machines went where?
2 answers:
32 were shipped to the western warehouse and 18 shipped to the Eastern warehouse. 25x18=450 20x32=640 (400+600=1000) + (50+40=90) 1000+90=1090
E + w = 50.....w = 50 - e 25e + 20w = 1090 25e + 20(50 - e) = 1090 25e + 1000 - 20e = 1090 25e - 20e = 1090 - 1000 5e = 90 e = 90/5 e = 18 <=== the east got 18 w = 50 - e w = 50 - 18 w = 32 <=== the west got 32

A half-life of the isotope is 15 days and at start its mass is 32 g. A table: t: m: 0 32 g 15 16 g 30 8 g 45 4 g 60 2 g 75 1 g In the first column is used an arithmetic sequence ( a 1 = 0, d = 15 ). In the second column is used a geometric sequence ( a 1 = 32, r = 1/2 )
(180-x) + 18 + 30 + x/2 = 180 => 180 + 48 - x + x/2 = 180 => -x/2 + 48 = 0 => x/2 = 48 => x = 48×2 = 96°
