Step-by-step explanation:
Let f represent the number of first-class tickets that Sarah bought. Then she bought (16-f) coach tickets. Her total spending for airfare was ...
1140f +160(16-f) = 9420
980f +2560 = 9420 . . . . simplify
980f = 6860 . . . . . . . . subtract 2560
f = 7 . . . . . . . . . . . . . divide by 980; number of first-class tickets
(16-f) = 9 . . . . . coach tickets
Sarah bought 7 first-class tickets and 9 coach tickets.

Answer: 12πins.
Step-by-step explanation:
Since the area if a circle = πr²
From the question
Area of the circle = 36πins²
To find the circumference of the circle, we need to find the common radius of the circle and this could be achieved from the area of the circle given above.
πr² = 36π, solving this gives. Divide through by π
r² = 36
r = +/-√36
= +/-6
Now to find the circumference of the circle, we substitute for r in the formula below.
Circumstances = 2πr
= 2 ×π × 6
= 12πins.
3+5=8
1200 voters
1200/8 = 150
Female: 5 x 150 = 750 voters
Male: 3 x 150 = 450 voters
