Answer:
63 = 5.5 * x + 30
x = 6
Step-by-step explanation:
Given hollow cubical box of side 0.30 m=3 dM
volume V=3^3=27 dm^3 = 27 L
Weight of box
= weight of (fresh) water (1 kg/L) displaced
= V/3 = 9 L of water = 9 kg
When water is filled so that the total weight of water equals the weight of volume of box, the top rim of the box will be at water level.
Remaining volume = 27-9=18L
height of 18L of water when water rushes in
= 18/(3^2) = 2 dm (=0.2m)
Answer:
5/2 inches
Step-by-step explanation:
If there is 25/4 squared inches, we could set this as an equation:
Now, since 25 and 4 is a perfect square, we could do this:
(distribute the square exponent to both 5 and 2 to get the original)
And since the exponent is the same, we can clearly tell x is 5/2 (or square root it)
