If the cylinder already has 3.6 Liters in it, adding 600 mL would make the cylinder have 4.2 Liters of water in it.
We know this because 600 mL converted to Liters equals 0.6 L. So 3.6 L + 0.6 L = 4.2 Liters.
80 x .72 = $57.60
Easy peasy
Step-by-step explanation:
2/3 lost is 1/3 kept
2/3 of the 1/3 kept is 2/9 lost
1/3 x - 2/9 x = 4
3/9 x - 2/9 x = 4
1/9 x = 4
x = 36
First she lost 2/3 of 36, which is 24. She had 12 left. Then she lost 2/3 of 12 which is 8. She had 4 left.
Since the area of the walkway is not given, it's substitution in the answer is x. You do have the measurements of the pool though. Area=length times width. 36 times 18 is 648. The area of the concrete is x-648 ft, because the pool is not apart of the concrete. The area of the walkway can be expressed by X-648 ft.
