Given the following equation, explain which statement is correct

67 + 33 = 70 + 30

a the equation is true because the sum of 67 and 33 is equivalent to the sum of 70 and 30.

b the equation is true because the sum of 67 and 33 is not equivalent to the sum of 70 and 30.

c the equation is false because the sum of 67 and 33 is not equivalent to the sum of 70 and 30.

d the equation is false because the sum of 67 and 33 is equivalent to the sum of 70 and 30.

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.
