okay... i'm translating this from japanese to english, so i dunno how much you're gonna understand... but plz try...

There is a two-digit number. The sum of the tenth number (the one on the left... like in 10 it is 1) and the ones number (like in 10 it is 0) is 9. The tenth number is 1 more than 3 times the ones number.

What are the two numbers in the number?

I'm horrible at math and I'm trying to solve a real problem. Let me explain. there are two mileage reimbursement programs. One pays a fixed sum (431 dollars) plus miles driven X 20.5 cents. the other pays 44.5 cents per mile with no fixed sum added. What is the number of miles I must drive to make the reimbursement equal? I'm trying to pick which one will be a better program for me, so I want to know how many miles I must drive to make the second program worth it.

Two 2.00 kg masses are connected by a 50.0 cm long rod of negligible mass. This rod can rotate in the vertical plane around a horizontal rotation axis through its middle. Initially assume the rod is balanced and sitting along the horizontal as shown below. Suddenly a 50.0 g spider drops onto one of the masses with a speed of 3.00 m/s. (a) What is the angular speed of the system just after the spider lands? (b) What is the fraction of kinetic energy after the spider lands to just before it lands? (c) Through what angle will the system rotate before coming to rest?

The "day" comes from one earth rotation

The "month" comes from earth and moon

The "year" from earth and sun

So where did the "week" come from?

First person to answer correctly, gets 10 points.

I looked on Wikipedia to confirm that, yes, honey can be kept at room temperature due too high sugar content and low moisture content inhibiting/killing bacteria and yeast. HOWEVER... I had this facial scrub from Bath and Body Works, from True Blue Spa, that quickly became mold-infested. My question, then, is two part: >>>1<<< Can liquid honey (food grade) be stored on the shelves and be resistant to most (common) simple bacteria and eukaryotes (mold included)? >>>2<<< Is it probable that the Bath and Body Works facial scrub was not in fact HONEY (with jojoba beads) if honey does in fact inhibit/kill mold? Perhaps they used a honey blend (high fructose corn syrup, etc, no honey) OR perhaps the moisture content was heightened sufficiently to allow mold growth (and easy spreading on the face)? >>>I don't want to get sick from the food grade honey. Thanks in advance. (i'm a molecular biologist, feel free to use big words)
