Answer:
There is 16 ounces in one pound.
52/16 = 3.25 lbs = 3lbs 4oz
Step-by-step explanation:
Answer:
30%
Step-by-step explanation:
150-105 = 45
(45 / 150 ) * 100 = 30%
Answer:
Length=16 ft
Width=8 ft
Step-by-step explanation:
Let width be w and length will be 128/w since area is product of length and width
Perimeter will be w+w+128/w. Note that along the river, fencing isn't needed that is why perimeter equals 2w+128/w
Getting the first differential of perimeter with respect to w then
![2-\frac {128}{w^{2}}](https://tex.z-dn.net/?f=2-%5Cfrac%20%7B128%7D%7Bw%5E%7B2%7D%7D)
At critical point
![2-\frac {128}{w^{2}}=0](https://tex.z-dn.net/?f=2-%5Cfrac%20%7B128%7D%7Bw%5E%7B2%7D%7D%3D0)
![2=\frac {128}{w^{2}}](https://tex.z-dn.net/?f=2%3D%5Cfrac%20%7B128%7D%7Bw%5E%7B2%7D%7D)
![w^{2}=64\\w=8](https://tex.z-dn.net/?f=w%5E%7B2%7D%3D64%5C%5Cw%3D8)
Therefore, since length is 128/w, length is 128/8=16 ft
Therefore, maximum length and width are 16 ft and 8ft respectively
