See each answer bolded below
Step-by-step explanation:
1. Area of the rectangle is 20 * 30 = 600
Area of the 6 circles is 6(25pi)
150pi/600 = 0.7854
1 - 0.7854 = 0.2146
convert to percentage 21.46%
2. 6/16 -> 3/8
Roughly 38% (37.5)
3. 10/24 = 0.41666666667 or 0.4167
41.66
roughly 42%
4. 12/36 -> 1/3
33.3333
33%

Answer:
a₁₂ = - 4194304
Step-by-step explanation:
the nth term of a geometric sequence is
= a₁ 
where a₁ is the first term and r the common ratio
here a₁ = 1 and r = 
= - 4 , then
a₁₂ = 1 × 
= - 4194304
