Suppose you are asked to find 91,321,972×0.007004. Doing a quick estimate by rounding the numbers in scientific notation, what v
alue would you expect the answer to be close to? (If you need a review of the estimation technique, watch the video Scientific Notation, Part 4.) 63×10^4
Correct
Notice that the expression rounds to (9×10^7)×(7×10^−3)=
63×10^7+(−3)=63×10^4
The ramrod establishes whether the firearm is loaded or unloaded. It thrusts the bullet down the barrel. It is marked by wrapping some tape around it ( at the muzzle end ). This is to effectively signal if the muzzleloader is empty or loaded.
Together with weathering and plate tectonic movements, Earth’s
volcanic eruptions and emission of lava has destroyed/covered many of the craters which
