Take first derivative of area function and set it to zero
da/dx=24 - 2x=0
Now it is set to zero add -2x to both side
24 - 2x = 0
24 = 2x
Now divide by 2 in both sides
12 = Width
Your width now is 12
Plug 12 into you equation like this:
24 (12) - 12^2= A
288 - 144 = A
144 = Area
144 feets is the maximum area using the width 24
A) (32 4/5) / ( 8 1/5) = how many hours Mr. Maxwell wrote
B)
(32 4/5 ) / (8 1/5) = 4 hours
converting mixed numbers to fractions, the initial equation becomes,164 / 5 <span>÷ </span>41 / 51<span>

Simplifying 820/205, the answer is<span>=4</span>
Answer:
There is 1,120 grams of salt in 32 liters of seawater.
Step-by-step explanation:
32 / 2 = 16
16 * 70 = 1,120

Answer:
25 minute
Step-by-step explanation:
Speed is the ratio of the total distance traveled to the total time taken to reach this distance. The formula for speed is:
Speed = total distance / total time taken
The total distance covered by the sloth = 60 ft, and the time taken = 5 minutes, hence:
Speed = total distance / total time taken
speed of the sloth = 60 ft / 5 minutes = 12 ft per minute.
We can calculate the time taken for the sloth to travel the length of the football field (i.e. 300 ft)
speed = distance / time
12 ft/minute = 300 ft / time
time = 300 ft / (12 ft/minute)
time = 25 minute
Answer:
A. P/2 - L = W
B. 9/5C + 32 = F
Step-by-step explanation:
A. P = 2L + 2W
P = 2(L+W)
P/2 = L + W
(P/2)-L = W
B. C = 5/9(F - 32)
9/5C = F - 32
9/5C + 32 = F
