Section 2.1: Exercise 96 Exercise 96 World grain demand. Freeport McMoRan projects that in 2010 world grain supply will be 1.8 trillion metric tons and the supply will be only ¾ of world grain demand. What will world grain demand be in 2010? (1.8).75=1.35 trillion metric ton/world grain demand for 2010 Section 2.2: Exercise 94 Exercise 94 Fahrenheit temperature. Water boils at 212°F. a) Use the accompanying graph to determine the Celsius temperature at which water boils. 100 degrees Celsius b) Find the Fahrenheit temperature of hot tap water at 70°C by solving the equation F=158 70=5/9 (F-32) (9/5) (70/1) = (5/9)(9/5)(F-32) (9)(14)= F-32 126=F-32 +32 +32 ____________________ 158=F Section 2.3: Exercise 16, 28, 76, 84 Exercise 16: a/4 – a/2 = -5 (4) a/2 – (4)a/2 = -5(4) 1a – 2a = -20 -1a = -20 -1a/-1 = -20/-1 a = 20 Exercise 28: 0.4x – 1.6 = 0.6x (100)0.4x – (100)1.6 = (100)0.6x 40x – 160 = 60x 40x – 160 – 160 = 60x – 160 40x = -100 40x/40 = -100/40 X = -2.5
