Answer:
2.7%
Step-by-step explanation:
Actual width = 45.5 meters.
Incorrect width = 44.25 meters.
Error = 45.5 - 44.25 = 1.25
Percentage error = 

= 2.74
≈ 2.7%
Hence, the percentage error = 2.7% which is given in the third option.
Answer:
A
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 100 = 256
a^2 = 156
a = 12.48
a = 12.5
Answer:
a₈ = 39366
Step-by-step explanation:
The terms have a common ratio between consecutive terms
r = 54 ÷ 18 = 162 ÷ 54 = 3
This indicates the sequence is geometric with nth term
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 18 and r = 3 , then
a₈ = 18 ×
= 18 × 2187 = 39366
