To solve the first question, you can break down the total amount to find the value corresponding to the ratio. By adding the ratio parts, \(3 + 7\) gives us \(10\). The amount corresponding to the first part is \(\frac{3}{10} \times R126.00\), which equals R37.80. For the second question, according to the laws of exponents, any non-zero number raised to the power of \(0\) equals \(1\). So \( (a+b)^0 = 1\), regardless of the values of \(a\) and \(b\) as long as they're not both zero. Janet's travel query states she covered 540 km at an average speed of \(120 \mathrm{~km/h}\). To find the time taken, you can use the formula: time = distance ÷ speed. In this case, \(540 km ÷ 120 km/h = 4.5\) hours. Answers: 1.1: A \( R 37,80 \) 1.2: C \( 1 \) 1.3: D \( 4.5 \) hours
