1 and 2 are 1/4 and 90 degrees
3. 360 degrees and 4/4
4. 180 degrees and 2/4
Karmin will make $18.4 for working an hour after the increase.
Step-by-step explanation:
Step 1:
First, we need to determine how much Karmin made an hour.
Karmin's hourly rate 
So Karmen made $16 every hour that she worked. She worked for 30 hours and earned $480.
She will get a 15% increase in her hourly rate this month.
Step 2:
We need to determine how much 15% of $16 is.
15% of $16 
So her 15% increase amounts to $2.4.
So the hourly rate for this month 
So Karmin will make $18.4 for working 1 hour.
Subtract 15 from both sides
You want to focus on isolating the variable (x)
Since it’s a 10 team league and each team plays with the other team twice then 10+10=20, thus there would be 20 games played
