$ 1 U.S. dollar = 0.76 euros
so $ 30 U.S. dollars = (30 * 0.76) = 22.8 euros <==
Answer:
B. (x-9)^2 + (y + 7)^2 = 4
Step-by-step explanation:
The standard form of a circle is (x-h)^2 + (y-k)^2 = r^2. Hopefully you can memorize that, because it's very helpful in these problems!
(h,k) is our center, and r is our radius, so plug those values into the standard form:
(x - 9)^2 + (y + 7)2 = 2^2
2^2 = 4, so
<u>B. (x - 9)^2 + (y + 7)2 = 4 is our answer!</u>
There is a 1/3 chance. Add up the shaded parts for a total of 120 degrees. 120/360 is 1/3
