Here are the solutions to the problems: 1124. Step 1: Calculate the discount amount for one toy car. The original price of one toy car is 420 tg. The discount is 15%. Discount per car = 0.15 × 420 tg = 63 tg Step 2: Calculate the total amount saved for 7 toy cars. The kindergarten buys 7 toy cars. Total savings = 7 × 63 tg = 441 tg The kindergarten saves 441 tg. 441 tg 1125. Step 1: Calculate the length of the rectangle. The width of the rectangle is 6 cm. The length is 75% longer than the width. Length = 6 cm + (0.75 × 6 cm) Length = 6 cm + 4.5 cm = 10.5 cm Step 2: Calculate the area of the rectangle. The area of a rectangle is given by the formula Area = Length × Width. Area = 10.5 cm × 6 cm = 63 cm^2 The area of the rectangle is 63 cm^2. 63 cm^2 1126. Step 1: Determine the percentage of tin in the bronze. Bronze is 85% copper, and the rest is tin. Percentage of tin = 100\% - 85\% = 15\% Step 2: Calculate the mass of copper in 5 kg of bronze. Mass of copper = 0.85 × 5 kg = 4.25 kg Step 3: Calculate the mass of tin in 5 kg of bronze. Mass of tin = 0.15 × 5 kg = 0.75 kg Step 4: Calculate how many kilograms more copper there is than tin. Difference = Mass of copper - Mass of tin Difference = 4.25 kg - 0.75 kg = 3.5 kg There is 3.5 kg more copper than tin. 3.5 kg Send me the next one 📸
