Answer:
18, 9, 27
Step-by-step explanation:
36 ÷ 2 = 18. Dividing by 2 is the same as multiplying by 50%.
36 ÷ 4 = 9. Dividing by 4 is the same as multiplying by 25%.
Since 25% • 3 = 75%, you can do 9 (from previous) • 3 to get 27.
Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation: 
where r is the radius
Plug in the given area 161 in.²
Divide both sides by π to isolate r²
Take the square root of both sides to isolate r
Therefore, the radius of the circle is approximately 7.16 in.
I hope this helps!
Answer:
2/5
Step-by-step explanation:
From the two points we have marked, they are clearly 10 units apart from -5 to 5, and the change in the y-axis is 4. So the change between the two points is 4/10 (rise over run).
4/10 simplifies to 2/5.
