2.16 x 5 = 216,000
because you need a number smaller than 10
next you just count how many times from the decimal till you get the number you are looking for
Aftershocks occur after the most major part of an earth quake happens. Earthquakes occur at fault lines near the tectonic border. They occur because of the sudden movement for staying rigid while they were edging closer and closer. So the sudden movement releases a large amount of tension buried deep below the earth creating or resulting in an earthquake.
What you do is you take the denominator and you divide it into the numerator.
(-7+2i)(3-5i)
=(2i-7)(-5i+3)
=-10i^2+41i-21.
Hope it help!
so he got for £95 and sold it for £133, so hmmmm the difference is simply £38.
if we take 95 to be the 100%, what is 38 off of it in percentage?
![\begin{array}{ccll} \pounds&\%\\ \cline{1-2} 95 & 100\\ 38& x \end{array} \implies \cfrac{95}{38}=\cfrac{100}{x}\implies \cfrac{5}{2}=\cfrac{100}{x} \\\\\\ 5x=200\implies x=\cfrac{200}{5}\implies x=40](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccll%7D%20%5Cpounds%26%5C%25%5C%5C%20%5Ccline%7B1-2%7D%2095%20%26%20100%5C%5C%2038%26%20x%20%5Cend%7Barray%7D%20%5Cimplies%20%5Ccfrac%7B95%7D%7B38%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B5%7D%7B2%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%20%5C%5C%5C%5C%5C%5C%205x%3D200%5Cimplies%20x%3D%5Ccfrac%7B200%7D%7B5%7D%5Cimplies%20x%3D40)
