Answer:
14400 blinks per day
Step-by-step explanation:
We need to convert minutes to days
60 minutes = 1 hour
24 hours = 1 day
The units will cancel leaving blinks per day.
150 blinks 60 minutes 24 hour 216000
---------------- * ---------------------- * ------------ = --------------- blinks/day
15 minutes 1 hour 1 day 15
14400 blinks per day
Option D: A(n) = a + (n – 1) d
Solution:
To identify the formula for finding the nth term of an arithmetic sequence.
Let a be the first term.
d be the common difference of the each term.
n be the term of the number.
A(n) be the nth term of the arithmetic sequence.
Arithmetic formula:
A(n) = a + (n – 1) d
Example: 1, 4, 7, 10, 13, 16, 19, ...
This is a arithmetic sequence.
a = 1, d = 4 – 1 = 3.
To find the 5th term:
Substitute this in the above formula, we get
A(n) = a + (n – 1) d
A(5) = 1 + (5 – 1) 3
= 1 + 4(3)
= 1 + 12
A(5) = 13
In the given sequence 5th term is 13.
Hence Option D is the correct answer.
A(n) = a + (n – 1) d
Answer:
6.5 , 6.7 , 6.734, 6.76
Step-by-step explanation:
67/10 = 6.7
2/4 = 1/2
Numbers we're working with,
6.76, 6.7, 6.734, 6.5
So, your answer from least to greatest is:
6.5 , 6.7 , 6.734, 6.76
