the answer to 365x4 is 1460
3x280+380+450+(365x2)=2400
The Logical answer is 730 however, when rounding terms apply the answer is 730.215 Therefore, the answer is rounded still to 730, Thus the answer to your question is the number #730.
Assuming you mean 2010 and 2013 simply...365x3 =1095 + 1 (2012 is a leap year) so 1096
days in 4 years 365x4 = 1460 days days in 5 weeks 5x7 = 35 days total days 1460 + 35 = ?
The Earth rotates on its axis once each day. It is, in fact, the rotation of the Earth that creates a "day".However, due to the revolution of the planet around the Sun the a day can be taken to mean in reference to the sun or in reference to stars. The difference is accounted for by noticing the difference between a sidereal day and a solar day. A sidereal day is the time it takes for the Earth to spin once in reference to the vernal equinox rather than in reference to the sun. Over the course of a year the difference between the sidereal days and solar days adds up to a day as the revolution of the Earth around the sun masks one entire rotation of the axis.
No. The year is only a leap year if it is divisible by 4. However, it is divisible by 100, it must also be divisible by 400 to be a leap year. For example, 2000 was a leap year, but 1900 was not. So 1896 was a leap year and the next leap year was 8 years later, in 1904. 2096 will be a leap year, but 2100 will not be and next will be 2104, so again there is a gap of 8 years. So it is usually, but not always a 4 year gap.
