Positive integer ÷ Negative integer = Negative integer
(1) A temperature above zero is represented as a positive integer.
\(15°F\) above zero \(=15°F\)
(2) A temperature below zero is represented as a negative integer.
\(15°F\) below zero \(=-15°F\)
\(-15°F\) is colder than \(-13°F\).
\(15°F\) is warmer than \(13°F\).
\(10°F\) above zero \(=10°F\)
\(5°F\) below zero \(=-5°F\)
The temperature of Sunday is shown in the figure.
\(\to\) The temperature of Monday was \(5°F\) colder than the temperature of Sunday, and Sunday's temperature was \(2°F\). So, the temperature of Monday,
A \(4\) feet below the pool's surface
B \(12\) feet above the pool's surface
C \(12\) feet below the pool's surface
D \(6\) feet above the pool's surface
Any location above the surface represents a positive integer and below the surface represents a negative integer.
A man standing \(5\) feet above the surface of the swimming pool, is represented by \(5.\)
He took a dive of \(9\) feet from there.
Now, the new location of the man is:
Location of the man is \(4\) feet below the surface of the pool.
Hence, option (A) is correct.
Option A is Correct
