Astudents skipped a step when he tried to convert 720 seconds into hours and he got the following incorrect result : 720 seconds (1hour/60 minutes)=12 hours. what conversion ratio did he skip in this multiple step conversion?

The student should convert the seconds to minutes first.

The student skipped the conversation ratio that 1 minutes = 60 seconds.

Step-by-step explanation:

60 seconds = 1 minutes

60 minutes = 1 hour

720 seconds x 1 hr / 60 min x 1 min / 60 sec = 0.2 hour

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
