The City Zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bi

Anna11 [10]

Let a and c represent, respectively, the price of an adult and a child ticket. We know that

$\begin{cases}3a+2c=78.94\\2a+3c=75.86\end{cases}$

Multiply the first equation by 3 and the second equation by 2 to get

$\begin{cases}9a+6c=236.82\\4a+6c=151.72\end{cases}$

Subtract the two equations to have

$5a=85.1 \iff a=17.02$

Plug this value in the first equation to get

$3\cdot 17.02+2c=78.94\iff 2c=27.88\iff c=13.94$

A wave emitted from a source has a frequency of 10 Hz and wavelength 2.5 m. How much time will it take to reach a person located

Vesnalui [34]

Time taken to reach a person located 5m from the source is 0.2s

<u>Explanation:</u>

Given:

Frequency, f = 10Hz

Wavelength, λ = 2.5m

Distance, d = 5m

Time, t = ?

We know:

velocity = f X λ

v = 10 X 2.5

v = 25 m/s

We know:

Distance = speed X time

On substituting the value we get:

5 = 25 X t

t = 0.2 seconds

Therefore, time taken to reach a person located 5m from the source is 0.2s
