Answer:
Domain: all real x values, Range: -4_<x_<infinity
Step-by-step explanation:
The Domain is the X values, and the range is the Y values
Machine can make 114 copies in 4 minutes and 45 seconds. So first convert 45 seconds into minutes. We will use ratio and proportion for that using 1 minute = 60 seconds. So let say X minutes = 45 seconds.
![\frac{1 minute}{60 seconds} = \frac{X minutes}{45 seconds}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20minute%7D%7B60%20seconds%7D%20%3D%20%5Cfrac%7BX%20minutes%7D%7B45%20seconds%7D%20)
solve for X as shown
![\frac{1}{60} \times 45 = \frac{X}{45} \times 45](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B60%7D%20%5Ctimes%2045%20%3D%20%5Cfrac%7BX%7D%7B45%7D%20%5Ctimes%2045%20)
= X
0.75 = X
So 45 seconds =0.75 minutes
So it takes 4 minutes +0.75 minutes = 4.75 minutes for machine to make 114 copies. We have to find copies made in 1 minute. So lets say it makes C copies in 1 minute. Again we will use ratio and proportion
= ![\frac{C copies}{1 minute}](https://tex.z-dn.net/?f=%20%5Cfrac%7BC%20copies%7D%7B1%20minute%7D%20%20)
Now solve for C as shown
= ![\frac{C}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7BC%7D%7B1%7D%20%20)
24 = C
So machine can make 24 copies in 1 minute. So thats the final answer.
To find the equavalent version of 3% as a decimal, we can divide by 100.
3 / 100 = 0.03
Therefore, the answer is 0.03.
Best of Luck!
