Science & Mathematics - 12 December 2007

Abbey Ruckles went to the Hillside Bank. She borrowed 3,000 at a rate of 12 3/4%. The date of the loan was september 10. Abbey hoped to repay the loan on january 29. Assuming the loan is based on ordinary interest, how much will Abbey totally repay on January 29?

I did:

P=3000
R=12.75%
T=5/12
I=PxRxT
I=3000x12.75x141/360
I=3000x .1275x.3916
I=149.81
Answer is 3149.81?

To me it seems that the organ of sight in its incipient form must have been inseparable from the neural network of the organism in which it developed.

The first organism to develop light-sensitive cells would have no use for them whatsoever if it didn't also have a region of its brain that was conditioned to interpret the data received. That implies that at least two very rare and complementary mutations must have randomly coincided in the same organism for its new apparatus to be of any benefit to its survival.

This seems very unlikely to me, so would you say sight in a very primitive form was somehow originally inseparable from that which processed the data, and from that point gradually evolved into eyeballs and the visual cortex etc?

I would guess twice the size of a rocket needed to get out of earth orbit and how will they get it up there for the return trip from mars?

We have a rocket parked in low height orbit around the Earth, which lies in the ecliptic plane, and want to launch the rocket outside the solar system without further help from other planets.

What is the best time of the year to initiate the launch fuel-wise?

I understand the dam is nearly completed but, are their civil engineering standards really adequate? Or maybe the standards are fine but how about the rigor to enforce those standards to be used, I could imagine in a couple of years the dam will start to wash out.....not that I am saying our rigor to enforce standards is higher (look at the big dig)
