Proof-of-Work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions on the distributed ledger or blockchain.

<h3>What is Proof-of-Work in  Cryptocurrency?</h3>
  • A type of cryptographic demonstration known as proof-of-work involves one party (the prover) demonstrating to another (the verifiers) that a certain amount of computational effort has been put forth.
  • Consequently, this spending may be easily verified by verifiers with little work on their behalf.
  • The goal of proof-of-work algorithms is not to demonstrate that a task was completed or that a computational challenge was "solved," but rather to prevent data modification by imposing onerous energy and hardware control constraints.
  • Environmentalists have criticized proof-of-work systems for using too much energy.
  • Later, Bitcoin popularized proof of work as the basis for agreement in a permissionless, decentralized network where miners compete to add blocks and create new money.

For the past year, Kayla, Inc., has sales of $44,432, interest expense of $3,074, cost of goods sold of $14,909, selling and adm
ryzh [129]

Answer:

$14,439.8

Explanation:

The computation of operating cash flow is shown below:-

The operating cash flow is shown below:

= EBIT + Depreciation - Income tax expense

where,

EBIT = Sales - cost of good sold - depreciation expense -  selling and administrative expense

= $44,432 - $14,909 - $4,965 - $10,816

= $13,742

Tax expenses =  ( Earnings before interest and tax - interest expenses ) × tax rate of 40%

= ($13,742 - $3,074) × 40%

= $10,668 × 40%

= $4,267.2

So, the operating cash flow

= $13,742 + $4,965 - $4,267.2

= $14,439.8

You open a savings account with a 0.5% per year nominal interest rate, and the economy experiences 3% per year inflation. a. Wha
Firlakuza [10]

Answer:

a. The nominal interest rate is 0.5%, and the real interest rate is -2.5%.

b. The purchasing power of money in the account will reduce.

Explanation:

a. What is the nominal and real annual interest rate on the account? The nominal interest rate is %, and the real interest rate is %.

From the question, we have:

Nominal interest rate = 0.5%

Inflation rate = 3%

In economics, the real is interest rate is calculated as follows:

Real interest rate = Nominal interest rate - Inflation rate = 0.5% - 3% = -2.5%

Therefore, the nominal interest rate is 0.5%, and the real interest rate is -2.5%.

b. What will happen to the purchasing power of the money you place in the account over time? The purchasing power of money in the account will

From the question, the interest rate attached to the savings account is a nominal interest rate. Since the nominal interest rate, unlike the real interest rate, is an interest rate that is not adjusted for inflation, the purchasing power of money in the account will reduce.

The Doright Door Company is considering outsourcing production of its door to Mexico. Use the weighted scoring method to evaluat
Gekata [30.6K]

Answer:

(A) Mexican supplier cost = $445,800 or $89.16 average cost.

In-house cost = $714,000 or $142.8

(B) Mexican supplier total weighted score = 0.265 or 22.43%

In-house supplier weighted score= 0.238 or 23.8%

(C) Yes, explaination below

Explanation:

Mexican Supplier cost breakdown:

Quota price $83 X 5000 = $415, 000

Transport cost

1. to transport 5000 doors would require making a total of 20 trips from Mexico to USA (5000/250 doors)

2. at a cost of $825 per trip, total cost to transport doors is = $16,500.

Sending Engineers costs and Negotiation cost =

$5000 + $1000

(Transport+Sending Engineers cost) =

$22,500

Inventory carrying cost= 20% of cost of storing the goods. (total of all other cost) 20% x 22500 = $8300

Total cost = $445,800 or $89.16 average cost.

Total weighted score average:

Using the formula;

Weight= score x rating

Score = Weight/rating (making score subject of the formula)

Mexican Weighted

score1= 16%/3 = 0.0533, + 0.12 score2, + 0.035 + score3, + 0.056 + score4. = 0.265.

American weighted score

Using same formula;

0.04 score1, + 0.15 score2, + 0.014 score3, + 0.034 score 4 = 0.238.

The company should outsource the product. Why? because it will reduce total cost of doors, making them cheaper for if they do so, resulting in higher profit.
