Answer:
A. 6, 24, 96, 384
Step-by-step explanation:
The recursive formula tells you that the next number in sequence is 4 times the previous one.
For first term 6, the second term is 4·6 = 24.
For 2nd term 24, the third term is 4·24 = 96.
For 3rd term 96, the fourth term is 4·96 = 384.
The first four terms of the sequence are ...
6, 24, 96, 384
__
You don't even need to figure all four terms. You know immediately which sequence is correct once you have found ...

I believe the answer is 3/14
not quite sure but thats my guess:)
Y=mx+b
Distribute 3 to (x-1), 3x-3
y+9=3x-3
Subtract 9 on both sides
y=3x-12( the answer)
It takes 11 seconds to scan one person. So we have this ratio to start with
11 seconds: 1 person
Divide both sides by 11 to get this new ratio
1 second: 1/11 person
1 second: 0.0909 person
So in 1 second, 0.0909 of a person can be scanned. This statement seems silly because we can't have a fraction of a person, but it helps with the next part as shown below. The next step is to multiply both sides by 1800 to get....
1 second: 0.0909 person
1800*1 second: 1800*0.0909 person
1800 seconds: 163.62 persons
In a span of 1800 seconds (equivalent to 30 minutes), about 163 people's lunches can be scanned. Unfortunately, none of the answer choices are 163. The closest thing is 180, but that is an overestimate. So I would ask your teacher if there is a typo somewhere.
Note: if it took exactly 10 seconds for each student (instead of 11), then the answer would be 1800*(1/10) = 1800*0.10 = 180.
Answer:
75 %
Step-by-step explanation
There are 5 squares and each has 25 so 75% is the answear
