Ответ:

Размеры:

1 дюйм = 2.45 см

Если появляются дробные части, то округляем в большую сторону

25 * 300 / 2.54 = 2953

30 * 300 / 2.54 = 3544

(I - объем информации, K - кол-во пикселей, i - вес одного пикселя / глубина цвета)

Дано:

K = 2953 * 3544 = 10465432 пикселей

i = 24 бит

I - ?

Решение:

I = K * i = 10465432 * 24 = 251170368 бит

251170368.0 бит = 31396296.0 байт = 30660.4453125 Кбайт = 29.94184112548828 Мбайт

Объяснение:

вот так всё и решаеться

Because accounting affects people in many different fields, public accounting and private accounting include specialized services.
Auditing is the accounting profession’s most significant service to the public. An audit is the independent examination that assure the reliability of the accounting reports that management prepares and submits to investors, creditors, and others outside the business. In carrying out an audit, CPAs (Certified Public Accountants) from outside a business examine the business’s financial statements. If the CPAs believe that these documents are a fair presentation of the business’s operations, the CPAs give a professional opinion stating that the firm’s financial statements are in accordance with generally accepted accounting principles, which is the standard. Why is the audit so important? Creditors considering loans want assurance that the facts and figures the business submits are reliable.
Stockholders, who have invested in the business, need to know that the financial picture management shows them is complete. Government agencies need accurate information from business.
Internal auditing is performed by a business’s own accountants. Many large organizations maintain a staff of internal auditors. These accountants evaluate the firm’s own accounting and management systems. Their aim is to improve operating efficiency and to ensure that employees and departments follow management's procedures and plans.
