Answer:
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours
Step-by-step explanation:
Its a very simple Expression.
First we consider the first temperature at first time which is 0°c at 12 noon which I initial time, i.e t= 0.
For every four hour change , the temperature adds -3/2°c .
So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c
The expression to know the temperature is
T = To + (-3/2°c)x
Where x is the fraction of 4 in hours

Answer:
7/165
Step-by-step explanation:
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242
I think this is what you do. Hope it helps!
Answer:
