<h3>
Answer: -2w^2 + 25w = 25 or -2w^2 + 25w - 25 = 0</h3>
================================================================
Explanation:
Refer to the diagram below. The width is w. We have two opposite and parallel sides equal to this. The other two parallel congruent sides are L = 25-2w meters long. We start with the total amount of fencing, and then subtract off the two width values, so 25-w-w = 25-2w.
The area of the rectangle is
Area = length*width
Area = L*W
Area = (25-2w)*w
Area = 25w - 2w^2
Area = -2w^2 + 25w
Set this equal to the desired area (25 square meters) to get
-2w^2 + 25w = 25
and we can subtract 25 from both sides to get everything on one side
-2w^2 + 25w - 25 = 0
side note: The two approximate solutions of this equation are w = 1.0961 and w = 11.4039 (use the quadratic formula or a graphing calculator to find this)
Complete question :
Chef Charming and his mother sell cheese steak sandwiches at their food truck. They use fresh onions, and cook them slowly to caramelize them before putting them on their sandwiches.
Charming found a pre-cooked onion that was $8.3 per pound AP$, with 100% Yield. He wants to save money but isn't sure if that is a better deal than cooking the fresh onions himself.
He currently pays an AP$ of $1.87 per pound for fresh onions, but his yield is 50% after peeling and cooking the onions. What is the EP$ for the fresh onions, after caramelizing?
Answer:
$3.74
Step-by-step explanation:
Cost of fresh onions = $1.87 per pound
Percentage yield = 100% after caramelizing
Therefore EP$ for the fresh onions after caramelizing will be :
(1 + percentage yield) * cost of fresh onions
(1 + 100%) * $1.87
(1 + 1) * $1.87
2 * $1.87
= $3.74
The answer is 18.
Just replace the x with 2
Answer:
22
Step-by-step explanation:
Working backwards
1+1 then x2 is 4
4+1 then x2 is 10
10+1 then x2 is 22
Answer: 0.014
Step-by-step explanation: 5 divided by 18!
