Answer:
6 blue marbles
Explanation:
(red / 10) * (red minus one / 9)
r(r-1)/90
2/15 = 12/90
r(r-1)/90 = 12/90
r² - r = 12
r² - r - 12 = 0
(r + 3)(r - 4) = 0
r = -3 or r = 4
red = 4; blue = 6
Answer:This answer is false.
Explanation:
Wind and moist air is drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances behind the mountains creating a drier side called the "rain shadow".
Over time, pressure continues to build in the tectonic plates, until suddenly, they shift in an earthquake. Aftershocks are common, but then a long time can pass before another one becomes likely.
