Lelechka [254]

Answer:

\begin{gathered} 1.1.1.300g\cdot\frac{0.001\operatorname{kg}}{1g}=0.3\operatorname{kg} \\ 1.1.2.400g\cdot\frac{0.001\operatorname{kg}}{1g}=0.4\operatorname{kg} \\ 1.1.3.500ml\cdot\frac{0.001lt}{1ml}=0.5\text{ lt} \\ 1.1.4.769.69\cdot0.001=0.769\text{ liters} \end{gathered}

Step by step explanation:

1.1.1 We know that 1kg is equivalent to 1000g, then we can convert:

300g\cdot\frac{0.001\operatorname{kg}}{1g}=0.3\operatorname{kg}

1.1.2 For 400g of tomatoes:

400g\cdot\frac{0.001\operatorname{kg}}{1g}=0.4\operatorname{kg}

1.1.3. For 500ml of water, convert this into liters. We know that a 1ml is 0.001 lt

500ml\cdot\frac{0.001lt}{1ml}=0.5\text{ lt}

1.1.4. Since capacity is represented by the following expression:

\begin{gathered} C=\pi\cdot\text{radius}\cdot\text{radius}\cdot\text{height} \\ C=\pi\cdot7\cdot7\cdot5=769.69cm^3 \end{gathered}

We know that 1 cubic centimeter is equal to 0.001 liters.

769.69\cdot0.001=0.769\text{ liters}

Ede4ka [16]

Answer:

This means the mock-up tank has a volume 216 times smaller than the initial tank.

Step-by-step explanation:

The ratio between volume is given by

\frac{V_2}{V_1}=\frac{(1/6)L^{3} }{L^{3}}  =\frac{1}{216}

This means the mock-up tank has a volume 216 times smaller than the initial tank.
