Get started for freeA steel track measures \(25 \mathrm{~m}\) at \(20^{\circ} \mathrm{C}\). At \(70{ }^{\circ} \mathrm{C}\) it measures \(25.01 \mathrm{~m}\). Calculate the percentage change in the length of the track as its temperature changes from \(20^{\circ} \mathrm{C}\) to \(70{ }^{\circ} \mathrm{C}\).
The volume of gas in a cylinder is \(1098 \mathrm{~cm}^{3}\). Pressure is increased and the volume changes to \(936 \mathrm{~cm}^{3}\). Calculate the percentage change in the volume of gas.
Express the ratio \(1 \frac{1}{2}: 3 \frac{1}{4}\) using only integers.
Divide 108 in the ratio \(\frac{1}{2}: \frac{1}{4}: \frac{3}{5}\).
A mass of \(176 \mathrm{~kg}\) is divided in the ratio 4:5:7. Calculate the mass of each portion.
