ANSWER
The ratio in the simplified form is
80:3
EXPLANATION
We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.
We obtain the ratio as follows:
![20:0.75](https://tex.z-dn.net/?f=20%3A0.75)
This is the same as
![20: \frac{3}{4}](https://tex.z-dn.net/?f=20%3A%20%5Cfrac%7B3%7D%7B4%7D%20)
We multiply each term in the ratio by 4 to obtain;
![20 \times 4:0.75 \times 4](https://tex.z-dn.net/?f=20%20%5Ctimes%204%3A0.75%20%5Ctimes%204)
This gives us,
![80:3](https://tex.z-dn.net/?f=80%3A3)
Answer:
22
Step-by-step explanation:
The standard form for an equation of a circle is
, where h is the x coordinate of the center of the circle, k is the y coordinate, and r is the radius of the circle. Therefore, the radius of this circle squared is 121, meaning that the radius of the circle is 11. Since the diameter of a circle is twice the radius, the radius of this circle is 22. Hope this helps!
