If the original recipe produces 12 cupcakes using 1 cup of milk and 4 eggs, then doubling the amount of milk and eggs would also double the number of cupcakes produced. Therefore, using 2 cups of milk and 8 eggs would produce 24 cupcakes.

If the recipe calls for 4 eggs and you only have 2 eggs, it means you have half of the required amount of eggs. Therefore, it would make sense to also use half of the required amount of milk, which is 1 cup. Hence, the correct answer is 1/2 cup.

If the recipe calls for one cup of milk and 4 eggs, and we want to triple the recipe, we need to multiply the number of eggs by 3. Therefore, 4 eggs multiplied by 3 equals 12 eggs. So, if we want to triple the recipe, we will need 12 eggs.

The given chemical equation A + B -> AB represents a synthesis reaction. In a synthesis reaction, two or more reactants combine to form a single product. In this case, the reactants A and B combine to form the product AB.

The bicycle mechanic can assemble 8 complete bicycles using the 10 frames and 16 wheels in the shop. Each bicycle requires 1 frame and 2 wheels. Since there are only 10 frames available, the mechanic can assemble a maximum of 10 bicycles. However, since each bicycle requires 2 wheels, a total of 20 wheels would be needed for all 10 bicycles. Since there are only 16 wheels available, the mechanic can only assemble 8 complete bicycles.

The molar mass of CH4 is 16 g/mol because carbon has a molar mass of 12 g/mol and hydrogen has a molar mass of 1 g/mol. Since there are four hydrogen atoms in CH4, the total molar mass is 12 g/mol + 4 g/mol = 16 g/mol.
