The correct option is
The center is located at (1, 3), and the radius is 6.
By making the given equation as in the general equation of the circle as following
x^2 -2x +1+ y^2-6y+9=26+1+9
(x-1)^2+(y-3)^2=36=6^2
So, the coordinates of the center (1,3)
And the radius=6
Answer: room 101 and room 107
Step-by-step explanation:
In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3
In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.
In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3
Therefore, room 101 and room 107 have the same ratio.
15/20 and 16/20
4/5 or 16/20 is greater
Okay so -6 + Y = 0
Y = his total score on the first day
so you can do 0- (-6)= Y
answer Y= 6
first day he got a score if 6
