Answer:
342 sq miles
Step-by-step explanation:
separated figure into 4 vertical pieces with the following dimensions:
5x31 rectangle: A = 155
4x13 rectangle: A = 52
3x13 rectangle: A = 39
trapezoid (h = 8; bases of 11 and 13): A = 96
4) You randomly select one card from a 52-card deck. Find the probability of selecting the 6 of hearts or the ace of diamonds.
Answer:
1/26
Step-by-step explanation:
There is only one 6 of hearts and only one ace of diamonds.
The probability of selecting the 6 of hearts is thus 1/52, and that of selecting the ace of diamonds is also 1/52.
The probability of selecting the 6 of hearts or the ace of diamonds is the SUM of these two results: 1/52 + 1/52 = 2/52 = 1/26.

A ferry began its journey at 08 00 and travelled 208 km towards its destination.
The average speed of the ferry was 32 km/h. What time did the ferry reach its
destination?
please help
answer:
14 30
Step-by-step explanation:
208/32=6.5
6.5 hours is 6 hours 30 min
08 00 + 6h 30min =14 30/2.30
The ferry reached its destination at approximately 14:30 or 2:30 PM.
To determine the time the ferry reached its destination, we need to divide the distance traveled by the average speed of the ferry.
Distance traveled = 208 km
Average speed = 32 km/h
Time = Distance / Speed
Time = 208 km / 32 km/h
Calculating this, we find:
Time = 6.5 hours
Since the ferry started its journey at 08:00, we can add 6.5 hours to that time to determine the arrival time.
08:00 + 6.5 hours = 14:30
Therefore, the ferry reached its destination at approximately 14:30 or 2:30 PM.
