There is a 6th grade math homework problem I need help with, regarding percentage bars. Can somebody help me?
The problem is worded terribly, unless the class already has an established vocabulary for this kind of problem. It doesn't really even say that the percent bar pictured is the one Marjorie used. That aside, it appears to me that you are correct: 15 and 44% are the answers to questions 2 and 3, respectively.The reason you should discard the 0.34 and 1% option is because the percent bar is explicitly described as having the 1% mark, so even if Marjorie had done no work, that mark would still be there.There are no other marks, and Marjorie is described as just looking at one train (dimples), so the 15/44% is the only possibility.This interpretation of this somewhat ambiguous question is, to me, makes the most sense with regards to the concepts that the authors are attempting to convey.
Help with with my math homework? 9th grade algebra?
m - [2 - (2 - m)] = m - [2 - 2 + m] = m - [m] =m - m =0 #2 result when -4x+6 is subtracted FROM 8x+6 8x + 6 - (-4x + 6 ) = 8x + 6 + 4x - 6 = 4x 10x-7 subtracted FROM 9x - 15 9x - 15 - (10x - 7) = 9x - 15 - 10x + 7 = -x - 8
MATH HOMEWORK HELP 9th GRADE ACCELERATED COORDINATE ALEGEBRA?
Population and Food Supply: The population of a country is initially 2 million people and is increasing at 4% per year. The country's annual food supply is adequate for 4 million people (now) and is increasing at a constant rate adequate for an additional 0.5 million people per year. a) Based on these assumptions, in approximately what year will this country first experience shortages of food? b) If the country doubled its initial food supply and maintained a constant rate of increase in the supply adequate for an additional 0.5 million people per year, would shortages still occur? In approximately which year? c) If the country doubled the rate at which its food supply increases, in addition to doubling its initial food supply, would shortages still occur? Can you try to explain how?
Math help, 9th grade level?
ok first question 6r-3=9r-6 take the three and add it to both sides which makes it 6r=9r-3 take the -3 and add it to both sides to make it 6r+3=9r divide 6r and 9r by six to get r+3=1.5 subtract the 3 from both sides to get r=-1.5 which is the answer Second question a+2=-2+9 add 2 to both sides then you get a=9 which is the answer hope this helps
