Answer:
a) see below
b) 40x20 meters
Step-by-step explanation:
Write down what you know:
- The area of the enclosure is length*width, so

- The length of the fencing is 80 meters, so

Now we have to combine these two equations above, and get rid of y in the process.
First rewrite the second as:

Then substitute for y in the first:

b) To maximize A, find the zero of the first derivative:

So y = (80-40)/2 = 20 meters.
Answer:
Groceries Galore
Step-by-step explanation:
1) Find the value of 1 egg for each shop.
<u>Max's Market: </u>
2.04 ÷ 6
= £0.34
<u>Groceries Galore:</u>
2.64 ÷ 8
= £0.33
<u>Fancy Foodstuffs:</u>
4.08 ÷ 12
= £0.34
Therefore, Groceries Galore's price per egg is cheaper.
If the diameter is 16, then the radius is 8.
A=(pi) r^2
8*8=64
64*3.14159265359=201.06
201.06 is your answer.

The number of unique cookout trays are possible is 500
<h3>How many unique cookout trays are possible?</h3>
The given parameters are:
Main items = 10
Sides = 10
Drinks = 5
The number of unique cookout trays are possible is
Cookout trays = Main items * Sides * Drinks
So, we have:
Cookout trays = 10 * 10 * 5
Evaluate
Cookout trays = 500
Hence, the number of unique cookout trays are possible is 500
