Answer:
<em>It will occur zero times between midnight and one o'clock.</em>
Step-by-step explanation:
<u>Least Common Multiple (LCM)</u>
Three events keep James from sleeping: his clock ticking every 20 seconds, a tap dripping every 15 seconds, and his dog snoring every 27 seconds.
All three events happened together at midnight. They will happen together again the first time the numbers 20, 15, and 27 have a common multiple. This is the LCM.
List the prime factors of each number:
20: 2,2,5
15: 3,5
27: 3,3,3
Now multiply all the factors the maximum number of times they appear:
LCM=2*2*3*3*3*5=540
(a) All the events will happen together again after 540 minutes.
(b) Since 540 minutes = 9 hours, this event won't happen again until 9 am. Thus, it will occur zero times between midnight and one o'clock.
<span>Given
number : 14 - 6x / 19
So we need to write this fraction as a sum or difference.
First, simplify the given number:
=> 14 – 6x / 19
=> <u>14 x 19 – (6x</u>)
19
=> <u>266 – 6x</u>
19
=> 266 – 6x = -2 * (3x - 133)
Thus, the final result would be:
=> <u>-2 * (3x - 133) </u> => This
will be the fraction sum or difference of the given number<u>
</u> 19

Answer:
20
Step-by-step explanation:
first do 75/50 = 1.5
then multiply red by 1.5
13 landed on red so
13 x 1.5 = 19.5
but since you round up it is 20
Answer: 10 meters
Explanation:
29 cm : blank meters
So how do we get from 348 cm to 29 cm?
To figure this out we divide.
348 divided by 28 = 12
we divided by 12 so we do the same with 120
120 divided by 12 = 10
So that’s the answer.
I hope this makes sense and helps you :)
Answer:
Step-by-step explanation:
Order is impotant since you could easily make a positve number negative and vice versa. You switch the order of 5 subtracted by y to y-5.
