Step-by-step explanation:
B. Its oxidation state is higher in the product than in the reactant
B. Negative describes the line because it is sloping downwards.
Your answer is 4/5, which is 80% or 0.8
If there are 20 marbles in total in the bag, and 4 blue ones, that means that the probability of taking a blue one is 4/20.
This means that the probability of not taking a blue one is 1 - 4/20, or 20/20 - 4/20, which equals 16/20 = 4/5

Answer:
3 and 4
and
2 and 6
Step-by-step explanation:
3×4=12
2×6=12
The measurements are:<span>
b</span>₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches<span>
Let x = length of base and leg
The formula for perimeter of isosceles trapezoid is P = b₁ + b₂ + 2(leg)</span><span>
Where: b = base
<span> P = b</span>₁ +
b₂ + 2(leg)</span><span>
<span> 28 = 3x + 5x + 2(x)</span>
<span> 28 = 8x + 2x</span>
28/10 = 10x/10
<span> 2.8 = x</span>
Now, substitute the values:
<span> P = b</span>₁ +
b₂ + 2(leg)</span><span>
<span> 28 = 3(2.8) + 5(2.8) + 2(2.8)</span>
28 = 8.4 + 14 + 5.6
28 = 28
Hence the measurements are:
b₁ =
8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂<span> =
2.8 inches</span></span>
