Ariel weighed a mitten on her balance and recorded a mass of 2.3 grams. Her teacher told her that there was obviously something wrong with her balance because it was giving her a reading, which was actually 3 grams. What was the percent error of Ariel’s balance?

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

1yd 1 ft = 1 1/12 1 1/3 1 1/2 1 1/6

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.
