An environmental agency studying the effects of drought on a lake found that the water level decreased at a constant rate during
the first few months of the drought. When the agency began its research, the depth of the lake was 346 feet. The table represents the agency’s susequent observations about the lake's depth. Which equation represents the depth of the lake, y, based on the number of weeks passed, x?
"y = -0.6x + 346" is the one equation among the choices given in the question that <span>represents the depth of the lake, y, based on the number of weeks passed, x. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has helped you.</span>
You would set this up as Part÷Whole=Percent÷100 Part=117 Whole= X Percent=78 117÷X=78÷100 Set these up as fractions and cross multiply. You will get 117×100=78X 117×100=11,700 Divide both sides by 78 and you get x=150 There were 150 problems
