Answer:
72°
Step-by-step explanation:
There are 5 blades, equally spaced. So the angle between adjacent blades is 360° / 5 = 72°. So you can rotate the fan 72° and the blades will align again.
y = number of days
35.50 + 18.25 y = 163.25
18.25 y = 163.25 - 35.50
18.25y = 127.75
y = 127.75 / 18.25
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25

Step-by-step explanation:
<h3>
Answer: They're all the same</h3>
====================================================
Reason:
means we have 6 copies of "2" multiplied out as shown in choice B. That explains how A and B are the same, and we can say

The parenthesis are optional, but I find they're handy to count the '2's easier.
----------------
Now notice that

So,

The last step is possible because we have two copies of
multiplied together.
This shows that choice C is equivalent to A and B.
-------------------
Lastly,

The jump to the last step is possible because we have three copies of
multiplied together.
This shows choice D is equivalent to the others.
All four expressions are the same.
They represent different ways to say the same number. That number being 64.
