The equation of a circle is <em>(x-h)^2+(y-k)^2=r^2</em>, where <em>(h,k)</em> is the center and <em>r</em> is the radius. Our equation will be (x-3)^2+(y+2)^2=25 (remember to always square the radius).

Answer:
Martina has 18,000
Step-by-step explanation:
- Set up the 4/5 the amount Tamara has as a proportion. 4/5 = x/20000
- Then cross multiply
- 4 * 20,000 = 80,000
- 80,000 = 5x
- Divide and get 16,000 (This is 4/5 of what Tamara has)
- Set up what Martina has as a proportion. 8/9 = 16,000/x
- Cross multiply 8x = 16,000 * 9
- 8x = 144,000
- Divide by 8
- 18,000 :)
Answer: A is the correct answer
12/6 + 2/3 + 3/4
MMC of 6, 3 and 4 is 12
So 24+8+9/12 = 41/12 = 3,41 approximately.
