The empty place equals with 6
Answer:
<h2>324 cubes</h2>
Step-by-step explanation:
We calculate how many cubes will fit along each edge:
12 in : 2/3 in = 12 · 3/2 = 18 cubes
2 1/6 in : 2/3 in = 13/6 · 3/2 = 39/12 = 13/4 = 3 1/4 → 3 cubes
4 in : 2/3 in = 4 · 3/2 = 6 cubes
(18)(3)(6) = 324
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
She would end up with:
1) A total of 15 inches of dowel (or 1' 3" - A foot and 3 inches)
2) Pieces that are 2 1/2" (inches) long.
Answer:
it is 1 and 8/9
Step-by-step explanation:
ok so u make a whole number into 9/9 which leave you 1 and 9/9; then u subtract 1/9 from that and get that please mark brainliest i need it
