Question

Fred is scuba diving. He stops 14.3 meters below the surface to look at a fish. Then he swims down 5.8 meters deeper to look at a reef. If he then swims up 3.2 meters, which is the BEST approximation of Fred's position relative to the ocean surface? Lena chose B as the correct answer. How did she get that answer? Please answer ASAP with every answer to each detail in question.

Choices: A - 12 meters B - 11 meters C - -17 meters D - -23 meters

Answer 1

roughly -17 if I am not mistaken

if you start at 14.3 meters below then go down 5.8 more (14.3+5.8=20.1) then swim back up 3.2 you'd be left with 20.1-3.2= 16.9 which rounded is 17 and since it's proportional to the surface you'd be down so negative. leaving you with -17. hope this helps

Answer 2

Answer: The answer is C(-17) meter

Step-by-step explanation: The best approximation of Fred's position relative to the ocean surface is,⇒ -17 meter.What is Decimal number?A decimal number is a number that consists of a whole and a fractional part.Given that;Fish position in the ocean is 14.3 meter below the surface.He swim down 5.8 meters deeper and then swims up 3.2 meters.Now, By the given conditions we can formulate;The Fred's final position = - 14.3 - 5.8 + 3.2 = - 20.1 + 3.2 = -16.9 = -17 (approx.)Thus, The best approximation of Fred's position relative to the ocean surface is,⇒ -17 meter.
