Let c be children and a adults.
3.5c + 7a = 1771 (the total revenue is equal to the amounts made off of people)
c + a = 331 (total number of people)
The second formula becomes a = 331 - c. This can be substituted into the first formula.
3.5c + 7(331 - c) = 1771 = 7*331 - 3.5c = 1771. 7*331 = 2317, so 3.5c = 2317 - 1771 = 546.
546/3.5 = 156 = c (number of children).
c + a = 156 + a = 331 => a = 331 - 156 = 175 (number of adults).
There are 156 children and 175 adults
option c) The line segment AC is the diameter of circle F.
<u>Step-by-step explanation</u>:
- The 'diameter' is the line segment that passes through the center of the circle.
- In the circle shown, F is the center of the circle.
- The line segments EB and AC passes through the center point F.
- Therefore, both EB and AC are the diameters of the given circle.
- From the options given, option c) AC is the correct answer.
