An amoeba splits by simple division and every split takes 3 minutes to complete. When an amoeba is placed in a glass container, it took one hour to fill up the container. How long would it take to fill that same container if two amoebas were placed in the container?

I'm just feeling a little stuck, I can never seem to get in the right mindset right away for these things....

D is a point on BC such that AD is the bisector of angle A. Show that angle ADC = 90 + [(angle ABD - angle ACD)/2]

Thank you for any help!

In trig we get a bonus problem of the week. I have gotten many of them by myself so far... but this 1 nobody can figure out. Please don't call me a cheater because I have been working very hard on this all week and still no luck.....

-Solve the following cytogram from a college student to his parents. You must transpose the letters into digits to make the corresponding addition problem add up correctly.
- Each letter represents the same numeral each time it occurs, and a different numeral from every other letter.
-Equation:

~~~~~~ $SE.ND
~~~~~~ + MO.RE
= MON.EY

It is a normal addition problem, MON.EY being the answer.... Any help would be greatly appreciated thanks!

Here is what happened, I live with my parents when I had my first child for 2 months in their home on Yerba Buena Island (right next to Treasure Island in San Francisco) It was old officer housing 3 stories high with a basement. I stayed on the third floor, radio's which were unplugged played off and on, and noises in the side attics in the middle of the night. But one day I was home alone, and I saw a car pull up to the back of the house, 2 women got out and walked around the house to the front door. When I answered the door, they asked if anything strange ever happens on the 3rd floor, I said no, and that I did not live there. So I closed the door, and ran through the house to the back door to jot down their license plate # and there was no sign of a car or them anywhere around, and the driveway was long and the house very big, it would have taken them twice as long to walk back. Did they vanish so not to scare me, or did they want access to the house again? It was very scarey!
