x = arcsin (.81) = 54.096 degrees
16 is to 80% as x is to 100%
Set this up as a ratio
16/80% = x/100% multiply both sides by 100%
16/80 x 100 = x = 20
After you get your answer...hit the '=' buton again to get sci notation.
Other definitions of a 'mole' (LOL)
1. a small burrowing insectivorous mammal with dark velvety fur, a long muzzle, and very small eyes.
2.a spy who achieves over a long period an important position within the security defenses of a country.
-3(u+5)-3(u+6)=
-3u-15-3u-18 =
-6u-33
A mole is just a number ...(Avagadro's number)...just a QUANTITY
it is 6.022 x 10^23 no dimensions, just a very large number.
Total cost ==== 12 bottles x $28/bottle + $442 = $778
Average overall= total cost/#bottles = 778/25 = $ 31.12 per bottle
I will assume this is like a tilt up panel in a wall and the slab is vertical ...thus a right triangle is formed
sin = opposite / hypotenuse
sin 42 = 5.6/hypotenuse
hypotenuse = beam length = 5.6/sin 42 = 8.369 m
300/(9/12 x pi) = 127 rotations
Nice ! Way cool ! I was not quite there with my thinking.....
