The calendar obviously has an integral number of years and months in 400 years. If it has an integral number of weeks, then it will repeat itself after that time. The rules of the calendar eliminate a leap year in 3 out of the four century years, so there are 97 leap years in 400 years. The number of excess days of the week in 400 years can be found by ...
(303·365) mod 7 + (97·366) mod 7 = (2·1 + 6·2) mod 7 = 14 mod 7 = 0
Thus, there are also an integral number of weeks in 400 years.
The first day of the week is the same at the start of every 400-year interval, so the calendar repeats every 400 years.
The answer is no. the first equation is not right
Answer:
You are correct
Step-by-step explanation:
collinear means that they are on the same line, so they are collinear because of the definition of collinear
Answer:
Step-by-step explanation:
The rule for the translation is given as
The coordinates of F are (2,2).
We substitute these coordinates into the translation rule to find the coordinates of F'.
Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is 
then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.
