Answer:
The dimensions for the entire area will give the cheapest cost for the entire fence are 40 feet in front, 100 feet on each side, and 40 feet on bottom.
Explanation:
Since Mrs. Jones always wanted a white picket fence in front of her house, and Mr. Jones, her husband, wants a fence around the entire house including a decently-sized lawn in the front and a garden in the back, and the fence border should look like a rectangle, and I have calculated that he would need to fence off an area of 4,000 square feet in order to fit all these things, and he wants to appease his wife and at least build the white picket fence in front of the house, and he plans to build the rest of the fence with chain link, a cheaper material, given that a white picket fence costs $ 7 per foot and a chain link fence costs $ 4 per foot, to determine what dimensions for the entire area will give the cheapest cost for the entire fence, the following calculation should be performed:
Area of a rectangle = base times height = Z x Y = 4,000
80 x 50 = 4,000
40 x 100 = 4,000
20 x 200 = 4,000
20 x 7 x 2 + 200 x 4 x 2 = X = 280 + 1600 = 1880
40 x 7 x 2 + 100 x 4 x 2 = X = 560 + 800 = 1360
80 x 7 x 2 + 50 x 4 x 2 = X = 1120 + 400 = 1520
Therefore, the dimensions for the entire area will give the cheapest cost for the entire fence are 40 feet in front, 100 feet on each side, and 40 feet on bottom.
Answer:
The correct option is E
Explanation:
Isovalue lines define a relationship between the production of 2products in which the total market value is constant.
Value of the output can be calculated with following formula:
V= Pi*Qi+Pj*Qj
All industries try to achieve the highest value of the output that is possible. This can happen at point where isovalue line is tangent to PPF.
A is true.
Debit cards don't provide as much insurance: Credit cards are lending you money, so when a credit card gets stolen, the company wants its money back. They are the ones looking for it. With a debit card, you have to find it or replace the card.
Checks are rarely accepted; cards are widely used.
Debit cards have no interest rates or monthly charges.
