Leap years are years in which February has 29 days instead of 28. The device of leap year was invented to keep the calendar in s

goldenfox [79]

Answer:

As you know, a year has around 365 + 1/4 days.

This means that in two years, we have:

365 + 356 + 1/4 + 1/4 = 730 + 1/2

and so on.

adding this up, when we have 4 years we have a full day extra, this is:

1460 + 1

When we divide 1461 by 4, we have 365 with a surpass of 1.

The rule used to keep the calendar in sync with this extra day is adding an extra day to each fourth year.

So each fourth year, we have an extra day in Februray (the Februray 29th), this is called a bisiest year.

The "math rule" used to know if a year is leap or not is:

if a year is not divisible by 4, then it is a common year

else if the year is not divisible by 100 then it is a leap year,

else if the year is not divisible by 400, then it is a common year

if not, the year is a leap year.

Where "year" represents the number of the year.

bixtya [17]

Answer:

Therefore 1,460.57 liters will be made of petrolyn oil.

Step-by-step explanation:

Given that,

Petrolyn motor oil contains 5 liters of natural oil for every 7 liters of synthetic oil.

(7+5) liters= 12 liters petrolyn motor oil is made by 7 liters of synthetic oil and 5 liters of natural oil.

7 liters of synthetic oil used to made of 12 liters Petrolyn motor oil.

1 liters of synthetic oil used to made of $\frac{12}7$ liters Petrolyn motor oil.

852 liters of synthetic oil used to made of $\frac{12\times 852}{7}$ liters Petrolyn motor oil.

= 1,460.57 liters

Therefore 1,460.57 liters will be made of petrolyn oil.
