Deduction is a term used as inference to a known and validated principle. This is when you analyze points through logic from a given set of rules and conditions. You relate how the situation may conform to the rules. Thus. there is no wrong deduction. If you analyze it to be true, then that must be definitely correct. Therefore, the answer is letter B. What must be true.

a

the answer is a. 6 faces 12 edges and 8 vertices
Answer:
the question is incomplete, so I looked for a similar one:
<em>After the release of radioactive material into the atmosphere from a nuclear power plant, the hay was contaminated by iodine 131 ( half-life, 8 days). If it is all right to feed the hay to cows when 10% of the iodine 131 remains, how long did the farmers need to wait to use this hay? </em>
iodine's half life (we are given x, we need to find b):
0.5A₀ = A₀eᵇˣ
x = 8 days
we eliminate A₀ from both sides
0.5 = eᵇ⁸
ln 0.5 = ln eᵇ⁸
-0.69315 = b8
b = -0.69315 / 8 = -0.08664
since the farmers need to wait until only 10% of the iodine remains (we already calculated b, now we need to find x):
0.1A₀ = A₀eᵇˣ
0.1 = eᵇˣ
ln 0.1 = bx
where b = -0.08664
x = ln 0.1 / -0.08664 = -2.302585 / -0.08664 = 26.58 days
Answer:
113.04 cubic inches.
Step-by-step explanation:
We have been given that soft drinks are sold in aluminum cans that measure 6 inches in height and 2 inches in diameter.
To find the amount of drink contained in 6 cans, we will find the volume of 1 can using volume of cylinder formula.
, where,
r = Radius of cylinder,
h = Height of cylinder.
First of let us divide diameter of given cylinder by 2 to get the radius of our cylinder as diameter is 2 times the radius.
Upon substituting our given values in volume formula we will get,
Therefore, one can of soft drink contains 18.84 cubic inches of drink.
To find the amount of drink contained in 6 cans we will multiply volume of 1 can by 6.
Therefore, 6 cans of soft drink contain 113.04 cubic inches of drink.
