Mathematical Problems #8

1. Separate the product of the product of 999 and 7163 into sums that add to 999
example: 5 x 999 = 4995, 4 + 995 = 999.
2. Bobbym and Agnishom both leave Mathocity on their cars at the same time. Bobbym travels at a constant speed of 12 miles per hour and Agnishom at a constant 8 Miles per hour. Bobbym arrives at Sophopolis 2 hours before agnishom. How many miles is it from Mathocity to Sophopolis?
3. Find a 6 digit number whose numbers are l distinct such that when it is multiplied by 1, 2, 3 ,4, 5 or 6, the product contains the same set of digits.
4. When the Bobbym family went on vacation, mr bobbym traveled 4/9 of the distance at 40mph, 7/18 of the distance at 70mph, and the final 3- miles at 60mph. If there WERE NO STOPS, the entire trip took them X hours. find X.
5. Bobbym's water bill for every 30 days is $16. For the next 30 days the sprinklers were on everyday for 15 minutes 4 times per day.. His water bill then increased to 184. For the next 3 days he will have his sprinkers on every other day and ONLY ONCE for 15 minutes. His water bill for these 30 days should be...
2A x AB = 1971, A =B, find a + b.
6.(1-1/3)(1-1/4)...(1-1/50) =?
7. (2^100 + 3^100) modulus 5 = ?
8. (20-19+18....+2-1)/(19-18....+3-2+1) =?

The integral of hope is reality.
May bobbym have a wonderful time in the pearly gates of heaven.
He will be sorely missed.

Hi;

3. Find a 6 digit number whose numbers are l distinct such that when it is multiplied by 1, 2, 3 ,4, 5 or 6, the product contains the same set of digits.

What is I distinct?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
