Quoted: Dirk dug a hole that is 10 feet deep. How can you represent the magnitude of the hole's depth? a). 10 b). -10 c). |10| d). |-10 Absolute value is always positive, so C is the most correct answer. |

Quote HistoryQuoted: For starters the || lines mean “absolute value” of whatever’s inside. That means |10| = |-10|, so we can toss out C & D. That leaves A or B. I’m going with A because, while on a graph you can have negative magnitude… no one measures holes as “negative feet”. That’s just dumb. That not how math is taught. They want you to show the correct process, as well as derive the correct answer. D is the correct choice. |

Quote HistoryQuoted:
Dumb questions are dumb. The hole is 10 feet deep. Tell the court recorder to use whatever notation she likes to indicate that the hole is 10 feet deep. The purpose of math is to express things as clearly as possible. If you have people arguing, saying multiple answers are identical, then you're asking questions in a stupid manner. Long story short, a kid would probably learn more by going out in the yard and digging a 10 foot hole than he would by sitting down and answering that question. |

Just to provide an engineering example of where absolute value would be used. The acceptable error in a gauge, say on a pressure gauge in a petrochemical application, would be the absolute value of the difference between the correct reading and the gauge reading. You might see it expressed as 1% error, but that means the difference can be positive or negative.
So, you know, the absolute value of the difference. |

I love GD. We complain about Common Core and how stupid teachers, Millennials, and Boomers are yet 64% of you didn't answer A and are therefore wrong. When I was a TA grading lab reports I would have taken off points for any answer other than A. A is correct. Yes, others are equivalent but you ALWAYS give the most simplified answer unless otherwise stated. Square root of 100 is technically correct but if you gave that as the depth of a hole I'd ignore you.

In my opinion, A or C would be correct. The term 'depth' implies distance below the surface. Thus positive depth is towards the center of the earth. If the question would have asked about the magnitude of differential altitude, then A or D would have been OK.

That is a give them the answer they want type of question. You should teach your daughter that she will encounter many of these in school and that she should buck up and give them their answer, graduate, then never look back.
Accounting question: Could Dirk fill up the hole and depreciate the hole as it's being filled?

Can't help but chuckle a bit that a bunch of adults have gone through 4 pages and still don't have a consensus.

Quote HistoryQuoted: A quibble. "Now put the zero 3 feet from the opening. The depth is |(3 - 0) - (0-7)| = |10| = 10 feet." I would put that as |(3-0)| + |(0-7)| which evaluates to the same thing but clearer that you are adding two magnitudes. Quote HistoryQuoted: Quoted: Magnitude does not require "direction", it's a scalar number. Consider a number line, something a sixth grader recognizes. Dig a 10 foot deep hole. Put a number line divided in 1 foot segments in the hole aligned along its centerline. First, place zero at the opening of the hole at grade. The bottom of the hole is located at -10 feet on the number line. The depth is |-10|=10 feet. Put the zero on the number line at the bottom of the hole; the depth is |10| = 10 feet. Now put the zero 3 feet from the opening. The depth is |(3 - 0) - (0-7)| = |10| = 10 feet. 10 feet is a scalar value that is the magnitude of the depth in feet. The number line is not a unit vector, but there is only a tiny step needed to define a unit vector the same as the number line. A quibble. "Now put the zero 3 feet from the opening. The depth is |(3 - 0) - (0-7)| = |10| = 10 feet." I would put that as |(3-0)| + |(0-7)| which evaluates to the same thing but clearer that you are adding two magnitudes. In the method number lines are taught in olden times, direction along the line is applied; in this case move from 3 to 0, then 0 to -7 to count the magnitude. A sneaky vector as the direction is defined. It's not called a vector since sixth graders aren't quite ready, that would be a bit esoteric, and it's pointless for a generic hole that we're assuming is dug normal to a level grade. |

How can you represent the depth relative to ground level? 10 -10 |10| |-10| How can you represent the magnitude of the hole's depth? 10 -10 |10| |-10| For 3.b., it's obviously -10 for the first question because it doesn't ask for magnitude, and the next question does. The next question would be |-10| to show the magnitude: "For a hole which which has a depth below ground level (negative value), the depth (magnitude) of the hole is |-10|." It's slightly misleading of the OP to only post part of the problem (and in his other thread he posted part of 3.a., but it was the preceding part). I'm with you on 'safe thread'. |

Implausible. To dig 10 ft^3 would require 1 ft x 1ft, and no one makes a shovel that can do that. So they dug 10 ft down taking out 20 yards of dirt most likely. Permits, environmental impact for scrub jays and tortoise lairs, call before they dug and cut a sewer main? In FL, they'd hit water or limestone before 10 ft.
