A colony of bacteria has 10,000 bacteria and is growing exponentially. The inequality 10,000(4x) ≥ 320,000 represents the hours, x, for which the colony will have at least 320,000 bacteria. Which interval represents the hours when the colony will have at least 320,000 bacteria? a.) [2.5, ∞)
b.) [3, ∞)
c.) [32, ∞)

Required number = 1/2 (2/7 + 3/4) = 1/2 ((8 + 21)/28) = {1/2 × 29/28) = 29/56 Hence, 29/56 is a rational number lying halfway between 2/7 and 3/4.
