Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.

Answer:
= 21.6216% decrease
Step-by-step explanation:
Calculate percentage change
from V1 = 29.6 to V2 = 23.2
(V2−V1)|V1|×100
=(23.2−29.6)|29.6|×100
=−6.429.6×100
=−0.216216×100
=−21.6216%change
=21.6216%decrease

Step-by-step explanation:
All the names for the mathematical statement given as pi over 2 are π/2 rad and 90 degrees
<h3>How to determine all the names for pi over 2?</h3>
The mathematical statement is given as:
All names for pi over 2
Rewrite the mathematical statement as follows:
All names for pi/2
This can further be rewritten as:
All names for π/2
In the measurements of angles.
The value of π is 180 degrees
So, we have
π/2 = 180 degrees/2
Evaluate the quotient
π/2 = 90 degrees
Hence, all the names for the mathematical statement given as pi over 2 are π/2 rad and 90 degrees
