Answer:
Sean got 63/81 questions right as a fraction.
Step-by-step explanation:
Sean got 63/81 correct. If there was a total of 81 questions, you put that as your denominator.
Now ask yourself: Can you simplify?
Yes you can.
You divide each number from the fraction by 9.
63 / 9 = 7
81 / 9 = 9
7/9 questions that Sean got correct.
If you also want a percentage + grade, Sean would get 77% which would be a C+

Answer:
1/11
Step-by-step explanation:
First you have to times 1/3 and 1/2 and then you get 1/6. Then you add 1/3 and 1/2 and that's 1/5. then you add them both.
The standard equation of the circle is:
(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...
so
30.
(x-2)^2+(y-7)^2=16
31.
We need to find the radius...(I'll just use the Pythagorean Theorem)
r^2=6^2+8^2
r^2=36+64
r^2=100 (so the radius is 10) and its center is (-6,-8) so
(x+6)^2+(y+8)^2=100
