A and D because it is basically saying 3:36 so when you simplify it comes down to 1:12
In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.
Answer:
A = -2.2
B = -1.7
C = 1.87
D = 19.97
Step-by-step explanation:
A = 7.4 - 9.6 = -2.2
B = -2.2 + 0.5 = -1.7
C = -1.1(-1.7) = 1.87
D = 18.1 + 1.87 = 19.97

Answer: Choice C</h3>
The base 16 is the same as 4*4.
From there, the rule 
is used to get 
Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is 
which only works if the bases are both the same.
6 times 12 is 72 so 14 times 12 would be 168 if that is what you are looking for. So for that y=168 :-)
