Answer:

Step-by-step explanation:
The given equation is: 

so, we first isolate the exponential form that contains the unknown "z" in the exponent, by dividing both sides by 0.5:

Now we bring the exponent down by applying the natural log function on both sides, and then solve for "z":

 
        
             
        
        
        
B. 18.37
1990 - 1960 = 30 = t
Plug in the variable "t" to the equation and solve.
P (t) = 18.37
        
             
        
        
        
13 x 5 = 65
4 x 7 = 28 
28 + 65 = 93
Your error is in you said 13 x 65 is 75

Answer:
1:24pm
Step-by-step explanation:
Couple of ways to solve this. Here is one method
Convert all times to minutes and find the total number of minutes they spent on all 3 activities. Then convert to hours and minutes and subtract from the end time of 5;28 to get the start time of all activities which is also the start time of watching the movie (first activity)
So time spent:
Movie: 2 hours 18 minutes = 2 * 60 + 18 = 120 + 18 = 138 minutes
Card game: 34 minutes
Soccer: 1 hour 12 minutes = 1 * 60 + 12 = 72 minutes
Total time spent = 138 + 34 + 72 = 244 minutes = 4 hours and 04 minutes
Subtract 4:04 from 5:28 to get 1:24pm
Check
Movie watch starts at 4:04, ends at 1:24 + 2:18 or 3:42pm
Card game starts at 3:42pm ends at 3:42+0:34 ==> 4:16pm
Soccer starts at 4:16pm ends at 4:16pm + 1:12 ==> 5;28pm
