it means the sum of three sides of a triange is 209 simple..
147 is the highest break in snooker.
HB PencilsArtists and draftsmen can use a variety of pencil leads in different hardnesses (e.g. H1, H2) and colors.H=hard and B=black pencils are graded on how hard (therefore lighter line) or soft (therefore blacker line) they are an HB pencil is mid range between the 8H and the 8B.
Many pencils across the world and almost all in Europe are graded on the European system using a continuüm from "H" (for hardness) to "B" (for blackness), as well as "F" (for fine point). The standard writing pencil is graded HB.
30% of 209= 30% * 209= 0.3 * 209= 62.7
:a = .5(hb+c) :2a = hb+c :2a−c = hb :(2a−c)/h = b
It is a pencil gradation system. HB means hard black B means black and 2H means harder.H (2H, 4H, etc) are the harder leads, and therefore draw a lighter line; and B (2B, 4B, etc) are the softer leads, and therefore draw a darker line. HB is the very middle. The larger the number, the farther away from HB it is. So for instance, 6B will be darker than 2B, and 4H would be lighter than 2H.Read more: What_do_HB_B_2H_signs_in_pencils_mean
With pencils H stands for hard, B for black (soft), HB is between the two.
b hb
This gives us the equation: A = hb/2 + c To solve for c, we simply subtract hb/2 from each side! A - hb/2 = c c = A - hb/2
I don't quite understand what you mean by HB-2 pencil but if you mean HB pencil / #2 Pencil it is not the softest pencil. Pencils scale from 9H to 9B, (HB in the middle) and 9B would the softest and darkest pencil there.
