At the seventh meeting there would be 20 members. If you think about the question carefully there were 12 members at the first meeting, then they skipped 6 meetings, with each meeting being skipped or not written down they added 1 member, so you would add 2 members for the next 2 meetings. making 20 members.
Hope this helps!

Answer:
D
2*6 is not a decimal
1.1*6.5 equals 7.15
3.2*6.3 equals 20.16
3.1*3.9 equals 8.99
8.99 is the closest to 12
Answer:
B
Step-by-step explanation:
Circumference of a circle is:
C = 2πr
Area of a circle is:
A = πr²
The circumference of the well is 47 ft and the area of the well in the drawing is 0.641 cm². If we say r is the radius of the circle on the drawing in centimeters and R is the actual radius of the well in feet, then:
47 = 2πR
0.641 = πr²
Solving for each:
R = 47 / (2π) ≈ 7.48 feet
r = √(0.641 / π) ≈ 0.452 cm
The scale is the ratio of R / r:
R / r = (7.48 ft) / (0.452 cm) = 16.6 ft/cm
So 1 cm = 16.6 ft.
This isn't one of the options. Are you sure you copied the problem correctly?
Maybe you meant that the circumference is 4π feet, and the area is 0.64π cm². If so:
R = 4π / (2π) = 2 feet
r = √(0.64π / π) = 0.8 cm
R / r = (2 feet) / (0.8 cm) = 2.5 ft/cm
So 1 cm = 2.5 ft.
