If Christmas is on Wednesday for a leap year, then which day is January 1st of the same year ? |
|
Answer» Answer: A leap year starting on Wednesday is any year with 366 days (i.e. it includes 29 February) that begins on Wednesday 1 January and ends on Thursday 31 December. Its dominical letters hence are ED. The most recent year of such kind was 2020 and the next one will be 2048, or likewise, 2004 and 2032 in the obsolete Julian CALENDAR, see below for more.[1] Any leap year that starts on Monday, Wednesday or Thursday has two Friday the 13ths: those two in this leap year OCCUR in March and November. Common years starting on Thursday share this characteristic, but also have another in February. This leap year also has the shortest gap between Leap Day (February 29) and the start of Daylight Saving Time in the US (March 8), only by 8 days as well as the shortest gap between Halloween and the end of Daylight Saving Time in the US, only by one day. PRIOR to 2007, this leap year had the longest gap between the end of Daylight Saving Time in the US and Halloween by 6 days. In this leap year, Martin Luther King Jr. Day is on January 20, Valentine’s Day is on a Friday, President's Day is on February 17, the leap day is on a Saturday, Saint Patrick’s Day is on a Tuesday, MEMORIAL Day is on its earliest possible date, May 25, U.S. Independence Day is on a Saturday, Labor Day is on its latest possible date, September 7, Halloween is on a Saturday, Veterans Day is on a Wednesday, Thanksgiving is on November 26, and CHRISTMAS is on a Friday. Also like a common year starting on Thursday, this leap year is the only one where Memorial Day and Labor Day are not 14 weeks (98 days) apart: they are 15 weeks (105 days) apart in this leap year. Interestingly, like common years starting on Thursday, this leap year also has the shortest gap between Halloween (October 31) and the end of Daylight Saving Time in the US (November 1) by one day. Prior to 2007, this leap year had the longest gap between the end of Daylight Saving Time in the US (October 25) and Halloween by 6 days. The Election Day in the USA is on November 3rd, as well in common years starting on Thursday. Step-by-step explanation: |

Answer» It is GIVEN that there are 32 students in section A and 36 students in section B. To DETERMINE the minimum number of books REQUIRED to distribute equally among students of section A and section B, we NEED to find the LCM of 32 and 36. To find the LCM, we find the prime factors of 32 and 36 as follows: Prime factors of 32 are 2. Prime FACTORIZATION of 32 in exponential form is: Prime factors of 36 are 2,3. Prime factorization of 36 in exponential form is: Now multiplying the highest exponent prime factors to calculate the LCM of 32 and 36, we have: LCM (32, 36) = Hence, the minimum number of books required to distribute equally among students of section A and section B are 288. |
