Answer:
Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes: 12.5 hours = 750 minutes. Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute? This requires you to set up the question as a proportion: (775 steps/ 750 minutes) = (x steps/1 minute)

For number 1, I think its C because that makes the number 55000
Step-by-step explanation:
Centre of circle(h,k)=(1,-4)
radius of the circle(r)=2
Equation of the circle is,
(x-h)^2+(y-k)^2=r^2
(x-1)^2+(y+4)^2=2^2
x^2-2x+1+y^2+8y+16=4
x^2+y^2-2x+8y+13=0 is the req.equation of the circle.
