Step-by-step explanation:
Writing and solving an equation of ratios would seem to be the best way to go.
0.045 sec 3 sec
------------- = ------------
1 image x
Then 0.045x = 3, and x = 66 2/3 images, best rounded down to 66 images.
Answer:
arithmetic sequence
Step-by-step explanation:
There is a common difference between consecutive terms , that is
d = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3
This indicates the sequence is arithmetic with common difference d = 3
Make 2 1/3 improper: 7/3. Make 40 a fraction: 40/1. Multiply 7/3 by the reciprocal of 40/1 (that means the fraction upside down: 40/1=1/40): 7/3x1/40=7/120. 2 1/3 divided by 40 is 7/120 :)
