Answer:
9:52
Step-by-step explanation:
First, let's rewrite "twenty-seven minutes past six", into a standard digital clock form. We could write 6:27. Now, it's easier to see that if we add 3 hours first, we would get to 9:27. And then if we add 25 minutes, we will get to 9:52.
Answer:
The answer is 161.5
Step-by-step explanation:
Step-by-step explanation: The top half of the kite is 6 in times 17 in because 8.5 + 8.5 = 17 so its 102. Half of 102 is 51 so 51 is the area of the top half. The bottom half is 13 in times 17 in which equals 221. Half of 221 is 110.5. Then 110.5 + 51 = 161.5... So your answer is 161.5 square inches.
