Answer: Second option is correct.
Step-by-step explanation:
Since we have given that

where, N represents the number of bacteria after 'h' hours.
So, we have given that there are 450 bacteria present.
N = 450
According to question,

Hence, Second option is correct.
The answer is 60 degrees as well
4/3 can be written as 4:3 or 4/3 and is a real number
Answer:
m∠BCD = 120°
Step-by-step explanation:
Since the interior angles of a quadrilateral add up to 360°, then we get:
2x+x+2x+x=360°
6x=360°
<em>Divide both sides by 6</em>
x=60°
Since ∠BCD's value is 2x and x is equal to 60°, then ∠BCD is 120°.
Answer:
x ≈ 33.0
Step-by-step explanation:
The third angle in the triangle is
180° - 70° - 76° = 180° - 146° = 34°
Using the Sine rule in the triangle
=
( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x =
≈ 33.0 ( to the nearest tenth )
