In the pipe flange shown to the right, the ten bolt holes are equally spaced. What is the spacing of the holes, in degrees?
1 answer:
The Solution:
The total degree of the pipe flange is 360 degrees.
It is given that the pipe flange has 10 bolt holes that are equally spaced.
This means that the spacing between the 10 bolt holes can be calculated as below:
Thus, the spacing of the bolt holes (in degrees) is 36 degrees.
Therefore, the correct answer is 36 degrees.

Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= a
where re a is the first term and r the common ratio
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3 ← common ratio
and a = - 3, thus
[te x]a_{n}[/tex] = - 3 ← explicit formula
