Total mass of the filled aquarium = 3*3 * 62 = 1674 pounds
As the table can only support 200 lbs the aquarium should not be put on the table.
(b) No the deisity of the water is a constant
6.50 + 1.50 = 8
8 × .20 = 1.6
8 × .7 = .56
8 + 1.6 + .56 = $10.16
The total cost is $10.16.
Hope this helps!
Y would equal 6.16.
We can use trigonometry and label AC as the hypotenuse and BC as the adjacent side.
This means we have to use the cosine ratio, cos = Adjacent/hypotenuse, and so to find the adjacent we must do cos(44.25) × 8.6, which is 6.16.
I hope this helps!
