Based on time conversion, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.
<h3>What is the age of a teacher who is 50 years in seconds?</h3>
The age of the teacher in years is converted to seconds as follows:
- 60 seconds = 1 minute
- 60 minutes = 1 hour
- 24 hours = 1 day
- 3651/4 days = 1 year
Thus:
50 years to seconds will be:
50 × 365.25 × 24 × 60 × 60 = 1577880000 seconds.
Therefore, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.

Answer: 18 animals
Step-by-step explanation:
3 out of 20 pet owners get their pet from a breeder.
To find how many animals have been bought from a breeder, you need to find 3/20 of the 122 animals.
3/20 = 0.15
122 * 0.15 = 18.3
18.3 rounds down to 18
There are 18 animals who have been bought from a breeder.
Answer:
see explanation
Step-by-step explanation:
Given
x² - 2x - 4 = 0 ( add 4 to both sides )
x² - 2x = 4
To solve use the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 4 + 1
(x - 1)² = 5 ( take the square root of both sides )
x - 1 = ± 
( add 1 to both sides )
x = 1 ± , thus
x = 1 + or x = 1 -
