Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.
Here is your solution.. hope it helps

Answer:
so 20*5=100 and a percent is out of 100
so we just multiply 18*5 which equals
90 so 18/20=90%
we could also figure this out because if we simplify we get
9/10 which is also 90%
Hope This Helps!!!
