Answer:
45.88 seconds
Step-by-step explanation:
= Time taken to sing the fist time = 
Time taken to sing the second time was 
less than the first time so
Time taken to sing the third time was 
less than the the second time
So the time it took the choir to sing the third time was 45.88 seconds.
The value of the expression would be 16.25 or 16 and 1/4, because when you multiply something by 1/2, you’re basically dividing it by 2, and when you put parentheses next to a number (for example 2(4) ), it means that you’re multiplying it, and when more than one values are in the parentheses, they all get multiplied, basically distributive property.
1 foot = 12 inches
Multiply to find the amount of inches.
12 * 2 = 24
Therefore, the answer is 24 inches.
Best of Luck!
