The profit for the fundraiser was $1,542.50 for 450 orders of pizza pies and individual pizza slices. Part A:

If x represents the number of pizza slices sold and y represents the number of pizza pies sold, construct a system of equations to model this situation

Which number completes the inequality? 2/3 < _ < 7/9

The function models the number of accidents

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function. a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
