Andrea was watching her brother in the ocean and noticed that the waves were coming into the beach at a frequency of 0.367347 Hz

anygoal [31]

Answer:

18 waves hit the beach in 49 s.

Step-by-step explanation:

Given:

The frequency of the waves that were coming into the beach is 0.367347 Hz.

Now, to find the number of waves that hit the beach in 49 s.

Let the number of waves be $n.$

The frequency of waves ( $f$ ) = 0.367347 Hz.

The time it takes to hit the beach ( $t$ ) = 49 s.

Now, we put formula to get the number of waves:

$f=\frac{n}{t} \\\\0.367347=\frac{n}{49} \\\\Multiplying\ both\ sides\ by\ 49\ we\ get:\\\\18.000003=n\\\\n=18.000003.$

The number of waves = 18.

Therefore, 18 waves hit the beach in 49 s.
