Waves of matter: Matter can also behave as a wave. This ran counter to the roughly 30 years of experiments showing that matter (such as electrons) exists as particles.

Answer 2

Step-by-step explanation:

10% of 50 coins is/are 5 coins. So, 5 coins are pennies.

40% of 50 coins is/are 20 coins. So, 20 coins are dimes.

The number of nickels is (5 + 9) = 14, according to the condition.

Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.

Now you can easily calculate the total and answer the question

Total = 5*1 + 14*5 + 20*10 + 11*25 = 550 cents = $5.50.
