Answer:
63
Step-by-step explanation:
Using the formula attached, we can setup the equation:
Then using a calculator you can solve
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.

Hola User_______________
Here IS YOUR Answer...!!!
_______________________
A.) 5.) 2/3 × 2/3 × 2/3 = (2/3)^3
6.) 4 × 4 × 4 = (4)^3
B.) 8.) (0.25) × (0.25) × (0.25)
9.) (1/9)×(1/9)×(1/9)
C.)
11.)3^3 = 9 and 4^3 = 64
12.)(4)^6 miles = 4096 miles
The answer is letter C.) 603.40
The minimum required score can solved using the equation
<span>MRS = mean + (zscore)(SD)
where z score of 0.03 is 1.88
</span>MRS <span>= </span>500 + (1.88)(55)
MRS = <span>603.40
