Answer from: Quest
an = 22 + (n-1) *6
110 seats
step-by-step explanation:
an=a1+(n-1)(d)
a1 = 22 this is the first item in the sequence
d =6 this is how the sequence goes up
a) an = 22 + (n-1) *6
b) a12 = 22 + (12-1) *6
a12 = 22+11*6
a12 = 22 +88
a12 = 110

The key is the word about, they want an estimation.63 is closer to 60, 71 is closer to 7060 + 70 = 130ryan counted about 130 birds
Answer from: Quest
the formula for converting absorbance to transmittance goes as:
a = log (1/t) a = 2 - log(%t) 10^a = 1/t t = 10^-a %t = 100(10^-a)
so at the given value of a, a = 1.5
%t = 100(10^-1.5)
%t = 3.16%
