Answer:
The answer to your question is ∠B = 47, ∠F = 69, ∠H = 62, ∠K = 51
Step-by-step explanation:
To find the values of the angles, use the theorem that states that the sum of the internal angles in a triangle equals 180°.
-Find A
∠A + ∠B + ∠C = 180°
82 + ∠B + 51 = 180°
∠B = 180 - 82 - 51
∠B = 47°
-Find F
∠E + ∠F + ∠D = 180
49 + ∠F + 62 = 180
∠F = 180 - 49 - 62
∠F = 69°
-Find H
∠G + ∠H + ∠I = 180
∠H = 180 - 49 - 69
∠H = 62°
-Find K
∠J + ∠K + ∠L = 180°
82 + ∠K + 47 = 180°
∠K = 180 -82 - 47
∠K = 51°

Step-by-step explanation:
The perfect square of this equation is , since the square would be . 1/4=4/16, meaning that you can set up the equation in the following way:
Take the square root of both sides:
Add 1/2 to both sides:
. Hope this helps!
Answer:
5 generations
Step-by-step explanation:
Data provided in the question:
Number of bacteria at the beginning of a time interval
, B = 4
Number of bacteria at the end of the time interval, b = 128
Now,
The relation between the bacteria at the beginning, bacteria at the end and the number of generations (n) is given as:
b = B × 2ⁿ
Therefore,
on substituting the respective values, we get
128 = 4 × 2ⁿ
or
2ⁿ = 32
or
2ⁿ = 2⁵
or
n = 5
hence,
5 generations
The answer would be d 40%
