Answer:
12.5H
Step-by-step explanation:
Number of hours worked per day:
Tuesday = 3 hours
Wednesday =5 hours
Thursday = 4.5 hours
H = hourly pay rate
Total amount earned = 3 hours × H + 5 hours × H + 4.5 hours × H
= 3H + 5H + 4.5H
= 12.5H
The expression which shows the total amount she earned = 12.5H
Answer:
$20.40
Step-by-step explanation:
15 percent of 24 = 3.6
24 - 3.6 = 20.4
= $20.40

Step-by-step explanation:
Given
![Shape: Nonagon](https://tex.z-dn.net/?f=Shape%3A%20Nonagon)
Required
Angles of rotation that would not map the shape on itself
Side of a nonagon is:
![Sides = 9](https://tex.z-dn.net/?f=Sides%20%3D%209)
and a complete rotation is:
![Complete\ Rotation = 360\°](https://tex.z-dn.net/?f=Complete%5C%20Rotation%20%3D%20360%5C%C2%B0)
To start with, we calculate a possible angle of each rotation:
This is calculated by dividing the complete rotation by number of sides
![Each\ Rotation = \frac{360}{9}](https://tex.z-dn.net/?f=Each%5C%20Rotation%20%3D%20%5Cfrac%7B360%7D%7B9%7D)
![Each\ Rotation = 40](https://tex.z-dn.net/?f=Each%5C%20Rotation%20%3D%2040)
The question lacks option; so, it's difficult to give a specific answer.
However, I'll give a generalized answer
For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)
i.e.
![Possible\ Angles = 40,80,120,160,200,240,280,320,360......](https://tex.z-dn.net/?f=Possible%5C%20Angles%20%3D%2040%2C80%2C120%2C160%2C200%2C240%2C280%2C320%2C360......)
<em>Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.</em>
