Answer:
36
Step-by-step explanation:
⅔ ×3³/5
⅔×18/5

15 15
=36
A=πr^2s/360 multiply both sides by 360
360A=sπr^2 divide both sides by πr^2
s=360A/(πr^2)
A 180° rotation just means to switch the signs of x and y and then swap them.
So if you have (3,5) it would become (-5,-3)
Answer:
16 oil changes
Step-by-step explanation:
You can write this into ratio form to help explain this. The ratio 4:2 can be used to explain this problem with the 4 meaning 4 oil changes and the 2 meaning after every two hours. You want to make it to where the 2 hours is at 8 hours so you would multiply 4 on both sides of the ratio which will give you the new ratio of 16:8. The mechanic can do 16 oil changes within 8 hours.
