Answer:
![\texttt{Submarine's depth relative to sea level after the first minute =}-\frac{4}{15}miles](https://tex.z-dn.net/?f=%5Ctexttt%7BSubmarine%27s%20depth%20relative%20to%20sea%20level%20after%20the%20first%20minute%20%3D%7D-%5Cfrac%7B4%7D%7B15%7Dmiles)
Step-by-step explanation:
Starting at sea level, a submarine descended at a constant rate to a depth of −4/5 mile relative to sea level in 3 minutes.
Total time = 3 minutes
![\texttt{Total depth descended in 3 minutes =}-\frac{4}{5}miles](https://tex.z-dn.net/?f=%5Ctexttt%7BTotal%20depth%20descended%20in%203%20minutes%20%3D%7D-%5Cfrac%7B4%7D%7B5%7Dmiles)
We need to find what was the submarine's depth relative to sea level after the first minute,
![\texttt{Depth descended in per minute =}\frac{-\frac{4}{5}}{3}=-\frac{4}{15}miles](https://tex.z-dn.net/?f=%5Ctexttt%7BDepth%20descended%20in%20per%20minute%20%3D%7D%5Cfrac%7B-%5Cfrac%7B4%7D%7B5%7D%7D%7B3%7D%3D-%5Cfrac%7B4%7D%7B15%7Dmiles)
![\texttt{Submarine's depth relative to sea level after the first minute =}-\frac{4}{15}\times 1=-\frac{4}{15}miles\\\\\texttt{Submarine's depth relative to sea level after the first minute =}-\frac{4}{15}miles](https://tex.z-dn.net/?f=%5Ctexttt%7BSubmarine%27s%20depth%20relative%20to%20sea%20level%20after%20the%20first%20minute%20%3D%7D-%5Cfrac%7B4%7D%7B15%7D%5Ctimes%201%3D-%5Cfrac%7B4%7D%7B15%7Dmiles%5C%5C%5C%5C%5Ctexttt%7BSubmarine%27s%20depth%20relative%20to%20sea%20level%20after%20the%20first%20minute%20%3D%7D-%5Cfrac%7B4%7D%7B15%7Dmiles)
Answer:
$1.00
Step-by-step explanation:
The tax rate in Nebraska = 5.5%
Cost of the shirt before tax = $18.20
Therefore:
Tax to be paid = 5.5% of $18.20
![=0.055 \times \$18.20\\=\$1.00 $(correct to the nearest cent)](https://tex.z-dn.net/?f=%3D0.055%20%5Ctimes%20%5C%2418.20%5C%5C%3D%5C%241.00%20%24%28correct%20to%20the%20nearest%20cent%29)
The amount you need to pay as tax is $1.00.
