Do you remember when you were learning about
Least Common Multiple (LCM) ? And you were
wondering what on Earth you would ever need it for ?
THIS IS IT !
The amount of time after 8 PM when the lights will flash
together again is the LCM of 20 seconds and 30 seconds.
Do you remember how to find it ?
... When 20 is prime-factored, you have 2 · 2 · 5 .
... When 30 is prime-factored, you have 2 · 3 · 5 .
... So the Least Common Multiple of 20 and 30 is 2 · 2 · 3 · 5 = 60 .
The lighthouses will flash together again in 60 seconds after 8 PM.
That'll be 8:01 PM.
X equals weight of permit fish
x + 10X = 132
11x = 132
x= 12

We are given vertices of a rectangle (0, −4) , (−1, −3) , (2, 0) , and (3, −1).
Length is the distance between (0, −4) and (−1, −3) points.
Width is distance between (−1, −3) and (2, 0) points.
<u>Computing length:</u>
<u>Computing Width :</u>
<h3>
Area of the rectangle = Length × Width </h3>

.
If you mean .152 bar as in .152152152.....then let x=.152 then:
1000x-x=152.152-.152
999x=152
x=152/999 (this cannot be reduced any further as they have no common primes)
