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)
Step-by-step explanation:
Use completion of sq method
x^2+y^2+14x+10y-7=0
(x+7)^2+(y+5)^2=7+49+25
(x+7)^2+(y+5)^2=81
so centre is(-7,-5) radius is9

Answer:
46.6 gallons
Step-by-step explanation:
351.6 miles = 16.4 gallons
1000 miles = x gallons
simply cross multiply
351.6 × x = 1000× 16.4 gallons
351.6x = 16400 gallons
x = 16400÷ 351.6
x= 46.643913538
x = 46.6 gallons (rounded to the tenth place)
