C30 typically refers to a specific type of concrete mix with a characteristic compressive strength of 30 megapascals (MPa) when tested at 28 days. It is commonly used in construction for structural applications where moderate strength is required. The "C" stands for "Concrete," and the number indicates the strength grade. This classification helps engineers and builders select the appropriate concrete mix for their projects.
30 c
So we have: the mean; (a + b + c)/3 = 10 yield that a + b + c = 30 (numbers in order) the range; c - a = 2 yield that c = a + 2 the median; b = 10.3 Substituting this information, we have: a + 10.3 + a + 2 = 30 2a = 17.7 a = 17.7/2 a = 8.85 yield that c = 10.85 So the numbers are 8,85, 10.3, and 10.85. Or, since b = 10.3 yield that a + c = 19.7 a + c = 19.7 -a + c = 2 add both equations 2c = 21.7 c = 18.85 which yield a = 8.85

21 / 30 is a 70%, or a C-.
30 - 32 = -2 -2 divided by 9 is -0.2222222 -0.2222222 times 5 = -1.1111111 So 30⁰F = -1.1111111⁰C
c in this case stand for "circa" latin for "around" or "in the general time of". Used by historians to denote an aproximate time for which an exact date is inappropriate. Means "somewhere around 69-30 BC"
30 c
c - 30 = 27-------------c = 57
30 c
30 F = (30 - 32) x 5/9 C = -10/9 C = - 1.1111 C
30 c = 86 f 30 f = -1.11 c
30 is the caliber or bore size. W is winchester. C is center. F is fire
mean or average = (a + b + c) / 3 = 10 so a + b + c = 10 * 3, so a + b + c = 30, so take your pick, 2 + 10 + 18, 11 + 4 + 15 etc
