Final answer:
The total number of days in a year, given m months in a year, w weeks in a month, and d days in a week, is calculated by the formula m×w×d, although real-world calendars also account for additional days beyond this simple calculation.
Step-by-step explanation:
The total number of days in a year expressed in equation form is calculated by multiplying the number of months in a year (m), by the number of weeks in a month (w), and the number of days in a week (d). So the equation to represent this would be A) m×w×d.
For example, if we had a standard calendar year where there are typically 12 months in a year, 4 weeks in a month, and 7 days in a week, we'd calculate the total days as follows:
- Months in a year (m) = 12
- Weeks in a month (w) = 4
- Days in a week (d) = 7
Therefore, the equation will become:
Total days in a year = m × w × d = 12 × 4 × 7 = 336 days
Note, however, that this is a simplification and does not account for the actual number of days in a year, which is usually 365 or 366 in a leap year. Calendars are complex and have evolved to include mechanisms like leap years to account for the variance between the calendar year and the solar year.
