Answer:
60480
Step-by-step explanation:
![nPr=\frac{n!}{\left(n-r\right)!}\\\\nPr=\frac{9!}{\left(9-6\right)!}=nPr=\frac{9!}{\left3\right!}=\frac{9*8*7*6*5*4*3*2*1}{3*2*1}=60480](https://tex.z-dn.net/?f=nPr%3D%5Cfrac%7Bn%21%7D%7B%5Cleft%28n-r%5Cright%29%21%7D%5C%5C%5C%5CnPr%3D%5Cfrac%7B9%21%7D%7B%5Cleft%289-6%5Cright%29%21%7D%3DnPr%3D%5Cfrac%7B9%21%7D%7B%5Cleft3%5Cright%21%7D%3D%5Cfrac%7B9%2A8%2A7%2A6%2A5%2A4%2A3%2A2%2A1%7D%7B3%2A2%2A1%7D%3D60480)
I'm guessing it's about 75 restaurants that have Hawaiian pizza on their menu. I just multiplied 7.5 by 10 because there are a 100 restaurants overall.
Answer:
It will take him <u>20 days</u> to read a 300-page book.
Step-by-step explanation:
Given:
Stephen read a 90-page book in 6 days.
If he continues reading at that rate.
Now, to find the time it will take him to read a 300-page book.
So, we solve using unitary method:
If, Stephen read 90 pages in 6 days.
So, Stephen read 1 page in =
days.
Thus, Stephen read 300 page in = ![\frac{6}{90} \times 300](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B90%7D%20%5Ctimes%20300)
![=\frac{1800}{90}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1800%7D%7B90%7D)
![=20\ days.](https://tex.z-dn.net/?f=%3D20%5C%20days.)
Therefore, it will take him 20 days to read a 300-page book.
