Step-by-step explanation:
No. of cartons packed by Joe in 4 hours=7
Therefore, No. of cartoons packed in 1hr=7/4
No. of cartoons packed by Bob in 6 hours=9
No. of cartoons packed in 1hr=9/6=2/3
Therefore,
Joe packed more cartoons than Bob
For number 9, you know that it makes 40 copies every five minutes. All you have to do is divide 40 by 5.
40 ÷ 5 = 8
It makes 8 copies every minute.
Your chart can also help you check your answer. It says that it makes 96 copies every 12 minutes and it makes 104 copies every 13 minutes. So multiply 8 by 12 to check it and 8 by 13.
8 • 12 = 96
8 • 13 = 104
Since those answers match up with the chart, it must be correct.
The photocopier makes 8 copies every minute. Hope that helps!
Answer:
A. ![a_n=2a_{n-1}](https://tex.z-dn.net/?f=a_n%3D2a_%7Bn-1%7D)
B. 160
Step-by-step explanation:
Silvia does 5 sit-ups on the first day of her exercise program. Each day thereafter she does twice as many sit-ups as the day before. Hence
1st day - 5 sit-ups
2nd day - 10 sit-ups
3rd day - 20 sit-ups
...
A.
![a_1=5\\ \\a_2=2a_1\\ \\a_3=2a_2\\ \\...\\ \\a_n=2a_{n-1}](https://tex.z-dn.net/?f=a_1%3D5%5C%5C%20%5C%5Ca_2%3D2a_1%5C%5C%20%5C%5Ca_3%3D2a_2%5C%5C%20%5C%5C...%5C%5C%20%5C%5Ca_n%3D2a_%7Bn-1%7D)
The recursive formula that models the number of sit-ups she does each day is
![a_n=2a_{n-1}](https://tex.z-dn.net/?f=a_n%3D2a_%7Bn-1%7D)
B.
![a_6=2a_5=2\cdot 2a_4=4\cdot 2a_3=8\cdot 2a_2=16\cdot 2a_1=32\cdot 5=160](https://tex.z-dn.net/?f=a_6%3D2a_5%3D2%5Ccdot%202a_4%3D4%5Ccdot%202a_3%3D8%5Ccdot%202a_2%3D16%5Ccdot%202a_1%3D32%5Ccdot%205%3D160)
