The false proportion is b.
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
The ocean floor directly beneath the boat is at a depth of = 180 meters
Submarine is at an elevation when it is above the ocean's surface = 2 meters
Total distance submarine needs to descends at a constant rate = 180+2=182 m
Rate of submarine descends = 0.4 meters per second.
Time taken by a scientist spend descending after boarding the submarine is given by
so, it must be less than 455 seconds.
therefore, it becomes x<455.
Hence, Option 'A' is correct.
Step-by-step explanation:
(note: I'm only answering the ones I know vs giving you wrong answers for the others!)
1. ROS=Obtuse (larger then ninty degrees)
2. octagon has 8 angles (octo means eight, after all!)
3. If a figure has three sides, it is a triagle (not positive on this one)
4. symmetric property of congruence (this one's a simple search :p )
5. N/A (although I believe its angle BEC=124 degrees, as every other choice Is proven to be true)
6. congruent complements theorem (this is because we are given that 3 is a suppliment of 4. we are also given that 2=4. Based on this, then 1=3 is congruent based on 1 being suppliment of 2, 2=4, and 3 being a suppliment of 4)
7. N/A
8. N/A (the picture is too fuzzy for me to make any ideas)
I'm sorry I couldn't solve them all, but I hope this at least gets you somewhere! Have a great day!
