Answer:
The total number of voters was 7488
Step-by-step explanation:
Let us solve this question using the ratio method
∵ The ratio of yes votes to no votes was 4 to 5
∵ There were 4160 no votes
∵ We need to find the total number of votes
∵ The total of the ratio = 4 + 5 = 9
→ By using the ratio method
→ YES : NO : Total
→ 4 : 5 : 9
→ x : 4160 : y
→ By using the cross multiplication
∵ 5 × y = 4160 × 9
∴ 5y = 37440
→ Divide both sides by 5 to find y
∵
= 
∴ y = 7488
∵ y represents the total number of voters
∴ The total number of voters was 7488
Because the distance to both chords are the same (5.70) and both chords are 90 degrees from the 5.70 line, both chords are identical.
Chord AB = 5, so chord CD is also 5.
Answer:
(1) a+1/a=8a+2/8a+1
(2) a²-1/a²=(a+1)(a-1))a²
(8a+2)(8a)/(8a+1)²
