Answer:

Step-by-step explanation:
The temp is 100 at time t = 0
After 1 sec, the temp difference would be:

After 2 sec, the temp difference would be:

Similarly for 3 seconds, 4 seconds etc.
We notice that the parenthesis part is 40% of it, so we can also write:
100(40%)^t,
where
t is the time
40% can be written as 40/100 = 0.4
SO, the function is:

Answer:
11. 16x +(9x+5)= 180
25x + 5 = 180
25x= 175
x= 7
If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.
112 + 4y= 180
4y = 68
y= 17
Step-by-step explanation:
12. 6x - 11 + 2x - 9= 180
8x - 20= 180
8x= 200
x= 25
6(25) - 11= 139
20y + 19 = 139
20y = 120
y=6
