If the original price is x, then x-0.10x=0.9x (which is a 10 percent off discount - 10 percent = 0.10 if you move the decimal spot 2 places over), then 10% of 0.9x is not 0.10x due to that 0.1/0.9=1/9, not 1/10. 1/10 of 0.9 is 0.09, so
0.9-0.09=0.81 of the original price
If the 10% sales tax was added first, it wouldn't matter since you're still getting 10% twice either way

Answer:
cost of the pool per cubic meters = $5
Step-by-step explanation:
The rectangular pool has a dimension of 30 m by 20 m by 2 m. To know the cost of the pool per cubic meter we have to calculate the volume of the pool . Then divide the total cost of the pool by it volume.
volume of the rectangular pool = length × height × width
volume of the rectangular pool = 30 × 20 × 2
volume of the rectangular pool = 1200 m²
The cost of installation is $6000 . The volume of the pool is 1200 cubic meters.
cost per cubic meters = total cost of installation/volume
cost per cubic meters = 6000/1200
cost of the pool per cubic meters = $5
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
