Based on the scenario, the initial temperature would be :
28 = (60) (1/2)^x/30 + 20
 
(60) (1/2)^0/30 + 20 = 60 + 20 = 
80 C
Hope this helps
        
             
        
        
        
angles formed by these tosses are   and
 and  degrees to the nearest hundredth.
 degrees to the nearest hundredth.
<u>Step-by-step explanation:</u>
Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.
The Law of Cosines (also called the Cosine Rule) says:

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
The Law of Sines (or Sine Rule) is very useful for solving triangles:

We can now find another angle using the sine rule:
⇒
⇒
⇒
So, the third angle =
Therefore, angles formed by these tosses are   and
 and  degrees to the nearest hundredth.
 degrees to the nearest hundredth.
 
        
             
        
        
        
Answer:
4 feet of distance between each other it is very simple and easy.
Step-by-step explanation:
They are both 6 feet and 10 feet away from each other so you just take 10-6 which is 4
