Yep, woke up only to go downstairs to find a wierd spider in my dogs food bowl.

It is probably around a half inch to an inch big, brownish color, one of the balls (body) is brownish and the other is black and tanish strips. (Black, tan, black)

What do you think?

1) Write as a single interval if possible: (3, ∞)∪[11, ∞)

2) Professor Dutuit gives only a mid-term exam and a final exam. The semester average is computed by taking of the mid-term exam score plus of the final exam score. To get a C, Max must have a semester average between 70 and 79 inclusive. If Max scored 100 on the mid-term exam, what range of scores on the final exam would give him a C ? Show your work.

3) The formulas
r = 0.07t + 2.27
and
w = 0.08t + 2.48
give an approximate model for the yearly average price r of a bushel of rye and w of a bushel of wheat over the past five years, where t is the number of years since 1994. What is the first year in which the price of rye exceeded $2.48/bu and the price of wheat exceeded $2.56/bu?

4) Audrey has 32 dimes and quarters in her piggy bank with a total value of $6.50. How many of the coins are dimes and how many are quarters?

thank you soooo much!!!! I appreciate all that help me with this! It's gibberish to me. :-)

still researching the northern Arizona area... found this....
"Elves Chasm pluton... oldest plutonic rocks... possible 'basement' substrate... contains mafic (hornblene-biotite tonalite) and intermedieate-composition plutonic units (quartz diorite), in cluding tabular amphilbolite bodies that may be dikes... about 1.84 Ga (billion years old)."

don't understand all that yet, but I'm working on it... just want to know if there's other areas where rock older than this is found exposed?.....

if a planet identical to ours (same sun, gravity, etc) was to form, is it inevitable that life would evolve in the exact same way it has on earth. Is evolution predetermined?

the respiratory system. It obviously has a lot to do with body temperature.

Astronomers have found visible evidence that gravity and other events can bend large widths of light so that light could be redirected back to us after being sent away from the source of the light. What is the possibility that some of the stars and galaxies are simply the light of our star, or galaxy being bent some where and reflected back to us, giving us more stars than we actually have?
