A = pi r^2
a = 3.14 * 97^2
a = 29,544.26 mm^2
Answer:
He has food for 9 days.
Hence, yes he has enough dog food to last one week.
Step-by-step explanation:
I believe the answer is A. I'm not too sure though. How did I come to this conclusion? ¯\_(ツ)_/¯
Depends on what you're trying to study
A+c=100
3a+2c=275, from the first c=100-a making the 2nd equation become:
3a+2(100-a)=275 perform indicated multiplication on left side
3a+200-2a=275 combine like terms on left side
a+200=275, subtract 200 from both sides
a=75, and since c=100-a
c=100=75=25
So the answer is D. 25 children and 75 adults
Equation 1: a+c=100
Equation 2: 3a+2c=275
