A machine produces 90 decibels of sound power. The inequality 90 + 10 log x ≤ 95 represents the number of identical machines, x, that can be used at the same time and produce less than 95 decibels of sound power. What is the maximum number of machines that can be used at the same time and produce less than 95 decibels of sound power?

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above

yes. we do proportions in probabilities.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
