$110,000
I got this answer from multiplying 10,000 by 10 then adding 10% of 10,000 (which is one thousand) 10 times, which got me an additional 10,000, and that's how I got my answer. Please comment on this answer and tell me if it is wrong, I really hope it isn't wrong. I also hope this helps you on your way, have a great day!
The answer is 3/5 meters per hour

ANSWER
![3\pi sq.\: in.](https://tex.z-dn.net/?f=3%5Cpi%20sq.%5C%3A%20in.)
EXPLANATION
Let R be the radius of the bigger circle and r, be the radius of the smaller circle.
Then their ratio is given as,
![R:r=3:1](https://tex.z-dn.net/?f=R%3Ar%3D3%3A1)
We can rewrite it as fractions to get,
![\frac{R}{r} = \frac{3}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7BR%7D%7Br%7D%20%3D%20%5Cfrac%7B3%7D%7B1%7D%20)
We make R the subject to get,
![R = 3r](https://tex.z-dn.net/?f=R%20%3D%203r)
The area of the bigger circle can be found using the formula,
![Area=\pi {r}^{2}](https://tex.z-dn.net/?f=Area%3D%5Cpi%20%7Br%7D%5E%7B2%7D%20)
This implies that,
![Area=\pi ({3r})^{2}](https://tex.z-dn.net/?f=Area%3D%5Cpi%20%28%7B3r%7D%29%5E%7B2%7D%20)
![Area=9\pi {r}^{2}](https://tex.z-dn.net/?f=Area%3D9%5Cpi%20%7Br%7D%5E%7B2%7D%20)
But it was given in the question that, the area of the bigger circle is 27π.
![27\pi=9\pi {r}^{2}](https://tex.z-dn.net/?f=27%5Cpi%3D9%5Cpi%20%7Br%7D%5E%7B2%7D%20)
We divide through by 9π to get,
![3 = {r}^{2}](https://tex.z-dn.net/?f=3%20%3D%20%7Br%7D%5E%7B2%7D%20)
This means that,
![r = \sqrt{3}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%7B3%7D%20)
The area of the smaller circle is therefore
![= \pi {( \sqrt{3}) }^{2}](https://tex.z-dn.net/?f=%20%3D%20%5Cpi%20%7B%28%20%5Csqrt%7B3%7D%29%20%7D%5E%7B2%7D%20)
Answer:
y= 1
Step-by-step explanation:
primero tienes que subtituir 3 en la x 2×3+y=7
6+y=7
-6. -6
y=1
