Answer:
Weight of a quarter = 6.25 grams
Weight of a dime = 2.5 grams
Step-by-step explanation:
The weight of a nickel is 80%
The weight of a quarter or the weight of a nickel is 5 grams or weight of a quarter =50.8 = 6.25 grams

Answer:
can you show a picture
Step-by-step explanation:
it depends on the situation and the problem but normally you would use the other numbers to figure out what number goes in "x"
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.
