Dennis_Churaev [7]

Answer: First option is correct.

The diver need to walk 188.2 units along the ocean floor to the wreckage.

Step-by-step explanation:

Since we have given from the figure shown below:

$AB=40\text{ meters}\\\\\theta=\angle {ACB}=12\textdegree$

Consider ΔABC,

$tan\theta=\frac{AB}{BC}\\\\tan12\textdegree=\frac{40}{BC}\\\\BC=\frac{40}{tan12\textdegree}\\\\BC=\frac{40}{tan{12\textdegree}\\\\BC=188.2\text{ units}$

So, the diver need to walk 188.2 units along the ocean floor to the wreckage.

Hence, First option is correct.

laila [671]

Answer:

Leon pay $448.2 for four days.

Step-by-step explanation:

Given:

Leon assembles an average of 9 machines per day.

He is paid $12.45 per machine.

Find pay for four days.

Leon pay $12.45 per machine and he is assembles an average of 9 machines per day.

So, he is pay for one day = pay for each machine $\times$ machines assembles in one day.

$=12.45\times 9$

$=112.05$

Leon pay $112.05 for one day.

So, he is pay for four days is

$=4\times 112.05$

$=448.2$

Therefore, Leon pay $448.2 for four days.
