let #N mean the number of days in year N. What is the value of #1988 +#1989 + #1990 + #1991?
A.1460
B.1461
C.1462
D.1463
step by step explanation:
1988 is a leap year the others arent.
so you do 366+365+365+365, which equals to 1461 or B.
To find the value of #1988 +#1989 + #1990 + #1991, we need to calculate the number of days in each of these years.
To calculate the number of days in a year, we need to consider whether it is a leap year or not. A leap year has 366 days, while a regular year has 365 days.
A year is a leap year if it is divisible by 4, except for years that are divisible by 100. However, years divisible by 400 are still leap years.
Let's calculate the number of days for each year:
#1988: Since the year is divisible by 4, it is a leap year. So, it has 366 days.
#1989: Since the year is not divisible by 4, it is a regular year. So, it has 365 days.
#1990: Since the year is not divisible by 4, it is a regular year. So, it has 365 days.
#1991: Since the year is not divisible by 4, it is a regular year. So, it has 365 days.
Now, let's add up the number of days:
#1988 + #1989 + #1990 + #1991 = 366 + 365 + 365 + 365 = 1461
Therefore, the value of #1988 +#1989 + #1990 + #1991 is 1461.
So, the answer is option B) 1461.
leap years have 366 days, all other years have 365
In your list 1988 was a leap year, so ....
