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 = 24m^{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} × 24m^{3} = 24000kg

The mass of the box = Box density × Box volume = 24m^{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

Please help!!
iragen [17]

Answer:

Option (C)

Step-by-step explanation:

Cost of ordering the number of shirts is represented by the function,

f(x) = 12.75x + 3.5

where x = number of players in the bowling team

Since number of players a bowling team can have,

6 ≤ x ≤ 10

Therefore, domain of the function: 6 ≤ x ≤ 10

For x = 6,

f(6) = 12.75(6) + 3.5

     = 80

For x = 7,

f(7) = 12.75(7) + 3.5

     = 92.75

For x = 8,

f(8) = 12.75(8) + 3.5

     = 105.5

For x = 9,

f(9) = 12.75(9) + 3.5

     = 118.25

For x = 10,

f(10) = 12.75(10) + 3.5

      = 127.5 + 3.5

      = 131

Therefore, for the given domain range of the function will be,

Range : {80, 92.75, 105.5, 118.25, 131}

Option (C) will be the answer.
