A rectangular box 4 meters long, 3 meters wide and 2 meters tall. On the box is a cat, and the box is floating in water such tha

Vikentia [17]

Answer:

Mass of the cat = 16800kg

Step-by-step explanation:

The volume of the box = its length * its breath * its height- 4m × 3m × 2m = 24 $m^{3}$

The standard density of water is 1000 Kg/ $m^{3}$

By Archimedes principle, the mass of a body floating body is equivalent to the mass of the volume liquid displaced

in this case we have

Mass of water displaced = Density of the water × Volume of the water displaced = 1000 Kg/ $m^{3}$ × 24 $m^{3}$ = 24000kg

The mass of the box = Box density × Box volume = 24 $m^{3}$ × 300kg/ $m^{3}$ = 7200 kg Hence the mass of water displaced = mass of the foating box + mass of th cat

24000kg = mass of cat +7200kg

mass of cat = 24000kg - 7200kg = 16800kg

£11000 of 3.9% compound interest of 3 years ?

FinnZ [79.3K]

Compound Interest

A = P(1 + r)^(n)

A = Amount, r = rate per year = 3.9% = 3.9/100 = 0.039, n = year = 3

A = P(1 + r)^(n)

A = 11000(1 + 0.039)^(3)

A = 11000(1.039)^(3) use calculator

A ≈ 12337.85

Compound Interest = A - P = 12337.85 - 11000 = 1337.85

So at the end of 3 years the Amount is ≈ £12 337.85 and the compound interest is ≈ £1 337.85

Hope this helps.
