Answer:
C) 42/7 = n
Step-by-step explanation:
A week is 7 days, so, to figure out how many cups of dog food she gives her dog daily, we would need to do her weekly amount, 42, divided by 7, the amount of days in a week :)
Answer:
2.6 hours
Step-by-step explanation:
use distance formula: d = r * t
83 = 32t
83/32 = t
2.6 = t
2.6 hours is 2 hours, 36 minutes
Let width = w
Let length = l
Let area = A
3w+2l=1200
2l=1200-3w
l=1200-3/2
A=w*l
A=w*(1200-3w)/2
A=600w-(3/2)*w^2
If I set A=0 to find the roots, the maximum will be at wmax=-b/2a which is exactly 1/2 way between the roots-(3/2)*w^2+600w=0
-b=-600
2a=-3
-b/2a=-600/-3
-600/-3=200
w=200
And, since 3w+2l=1200
3*200+2l=1200
2l = 600
l = 300
The dimensions of the largest enclosure willbe when width = 200 ft and length = 300 ft
check answer:
3w+2l=1200
3*200+2*300=1200
600+600=1200
1200=1200
and A=w*l
A=200*300
A=60000 ft2
To see if this is max area change w and l slightly but still make 3w+2l=1200 true, like
w=200.1
l=299.85
A=299.85*200.1
A=59999.985
