Find multiples of 30 and 40:

30: 30, 60, 90, 120, 150

40: 40, 80, 120, 160

The least common multiple is 120, so every 120 minutes they willl both ring.

1 hour = 60 minutes:

120/60 = 2 hours.

The bells ring together every 2 hours.

8 + 2  = 10 am

10 +  = 12pm

12 + 2 = 2 pm

The bells will ring together at am, 12 pm and 2 pm.

Answer:

<h2><u>Solution </u><u>:</u><u>-</u></h2>

At first common multiple of 30 an 40

\sf \to \: 30 = 30,60,90,120

\sf \to \: 40 = 40,80,120

Common Multiple = 120

Time taken = 120/60 = 2 hrs

Now,

8.00 + 2 = 10.00 am

10.00 + 2 = 12.00 noon

12.00 + 2 = 2.00 pm

Help&amp;EXPLAIN <br><br> Don’t use for points or will be reported and I’ll take the points back
anzhelika [568]

Answer:

X=151

Step-by-step explanation:

1. 61+90= 151

-Combine the two given angles

2.180-151= 29

-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.

-29 is your difference which is also the angle next to X.

3.180-29= 151

-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.

-Therefore X=151

Simplify the radical expression below.<br><br><img src="https://tex.z-dn.net/?f=3%20%5Csqrt%7B7%7D%20-%20%5Csqrt%7B63%7D%20" id=
anzhelika [568]

So for this, we can simplify √63 as such:


\sqrt{63}=\sqrt{7*9}=3\sqrt{7}


Using the simplified version of √63, we can solve it:


3\sqrt{7} -3\sqrt{7} =0


Zero is your final answer.
