A camera lens rotates 15° and then stops to take a picture.They it rotates 5 take another picture. The camera takes two pictures in each rotation cycle. How many cycles does the camera lens go through to reach 100 Justify your answer.

I was hoping that you would correct the grammar and spelling from you last post to make your question clearer.

That first part is not even needed, since you said in your second sentence that the camera takes two pictures in each rotation cycle.

So to take 100 pictures would take 50 rotation cycles.
Am I missing something here?

A camera lens rotates 15 degrees and then stops to take a picture.They it rotates 5 degrees take another picture. The camera takes two pictures in each rotation cycle. How many cycles does the camera lens go through to reach 100?

This is how it is in the book

To find out how many cycles the camera lens goes through to reach 100 pictures, we need to determine the number of pictures taken in each cycle and then divide 100 by that number.

According to the given information, the camera lens rotates 15° and then stops to take a picture. It then rotates 5° and takes another picture. This means that two pictures are taken in each cycle, one after a 15° rotation and another after a 5° rotation.

Therefore, in each cycle:
- 1st rotation (15°) → 1 picture
- 2nd rotation (5°) → 1 picture

So, the total number of pictures taken in each cycle is 2.

To find the number of cycles needed to reach 100 pictures, we divide 100 by 2:
100 / 2 = 50

Therefore, the camera lens goes through 50 cycles to reach 100 pictures.

Justification: This calculation is based on the given information that two pictures are taken in each cycle, one after a 15° rotation and another after a 5° rotation. By dividing the total number of pictures (100) by the number of pictures taken in each cycle (2), we can find the number of cycles required to reach 100 pictures.
