3.508 g/1000 g = .003508 kg
Answer:
x= 251
Step-by-step explanation:
300x= 190x + 27,610
300x-190x= 27,610
110x= 27610
x= 27610/110
x= 251
X2+5x+y2-y=-2
X2+2*5x2+(5/2)^2-(5/2)^2+y2-2*y/2+(1/2)^2-(1/2)^2=-2
(x+5/2)^2+(y-1/2)^2-13/2=-2
(x+5/2)^2+(y-1/2)^2=9/2
So centre =(-5/2,1/2)
Radius=(9/2)^(1/2)
I’m pretty sure the answer is A I hope that helps :)
