Answer:

B. 5¹³

(5²)⁴ * 5⁵

Add exponents when multiplying base numbers are the same:

5⁸ * 5⁵ = 5⁽⁸ ⁺ ⁵⁾ = 5¹³

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.

Average speed = (distance final - distance initial)/(time final - time initial)
Average speed = (30-0)km /(100 -0)min = 3/10 km/min

3/10 km/min *60 min/1 h = 180/10 km/h= 18 km/h
