Achurch rings its bells every 15 minutes, the school rings its bells every 20 minutes and the day care center rings its bells every 25 minutes. if they all ring their bells at noon on the same day, at what time will they next all ring their bells together? (answer in the form ab: cd without am or pm such as 08: 00)

5 : 00 PM

Step-by-step explanation:

Given,

Church ring bells every 15 minutes,

School rings its bells every 20 minutes,

And, day care center rings its bells every 25 minutes,

Thus, the number of minutes after which they will ring together = LCM (15, 20, 25)

∵ 15 = 3 × 5,

20 = 2 × 2 × 5,

25 = 5 × 5,

Thus, LCM (15, 20, 25) = 300

Now, 1 minute = 1/60 hours ⇒ 300 minutes = 5 hours,

Hence, after 5 hours they will ring together,

If they rang at 12:00 PM,

Then they will ring after 5 hours that is 5:00 PM.

14.4acres

Step-by-step explanation:

The total acres is 48 acres, which is 100%

when you add percentage of others, wheat and cotton you get 70%.

which leaves you with 30%

therefore, 30% of the land is for corn..

which is 14.4 acres.

0.30 x 48acres= 14.4 acres

hope this helped:)
