Answer:
Difference = 2.25°
Step-by-step explanation:
Here we are given that at depth the Temperature T is inversely proportional to the depth x.
∝ 

Where 4500 is constant
Now we have to find the difference in the temperature at 1200 mts and 3750 mts
1. x=1200



2. x=3750



Hence Difference is
T = 3.75 -1.20
= 2.25
Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°
Yeah, for example, 2*11=22 another example would be 11*5=55 I hope that helped you.
If A and J are complementary angles, that means that when they are added together, they equal 90 degrees. We can set up the equation 5x+30+4x+15=90.
5x+30+4x+15=90
9x+45=90
9x=45
x=5
