The magnitude, m, of an earthquake is defined to be m - logs, where is the intensity of the earthquake (measured by the
amplitude of the seismograph wave) and s is the intensity of a "standard" earthquake, which is barely detectable. which equation
represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake?
m = log 705
m-log(105)
m = log 10$
m-logo

Adam plans to choose a video game from the section of the store where everything is 75% off. he writes the expression d-0.75d to find the sale price of the game if the original price is d dollars. gena correctly writes another expression, 0.25d, that will also find the sale price of the game if the original price is d dollars. use the drop down menus to explain each part of adams and rena's expression
