If you would like to know the volume, you can calculate this using the following steps:
volume = 4/5 * 3 1/2 * 3 1/8 = 4/5 * 7/2 * 25/8 = (5*7)/(2*2) = 35/4 = 8.75
The correct result would be 35/4.

Answer:
no, it is good for 2 weeks (almost 3)
Step-by-step explanation:
The volume of the pool is ...
V = LWH
V = (20 m)(8 m)(1.8 m) = 288 m³
Then the amount of chlorine powder needed for 1 week is ...
(300 g/(50 m³)) × (288 m³) = 1728 g
A box of 5000 g holds enough chlorine for ...
(5000 g)/(1728 g/treatment) = 2.89 treatments
A box of chlorine powder is enough for 2 weeks, not 4.

Answer:
(-4 ; 5/2)
Step-by-step explanation:
2x² + 3x - 20 = 0
2x² + 8x - 5x - 20 = 0
2x(x+4) - 5(x+4) = 0
(x+4)(2x-5) = 0
x+4 = 0
x = -4
2x - 5 = 0
2x = 5
x = 5/2
