Question

students were asked to choose their favorite subject if 2/9 of the students chose history and 3/9 chose biology what fraction chose either history or biology

Answer 1

Explanation:

To relate the angular motion of the hour hand (h) and the angular motion of the second hand (s), we can use the following formula:

h = (s/360) * 30

The second hand makes a full rotation of 360 degrees in one minute, so in 60 minutes (or one hour), it rotates 21,600 degrees. We know that during this time, the hour hand moves 30 degrees.

Therefore, the equation relating h and s is h = (s/360) * 30.
