Question

для виготовлення порцеляни беруть глину, гіпс і пісок у таких відношеннях:маса гупсу відноситься до маси глини як 1:25,а маса піску відноситься до маси гіпсу як 2:1.Скільки цих матеріалів треба взяти, щоб виготовити 56кг порцеляни? дам 15 балов ​

Answer 1

Ответ:

Пошаговое объяснение:

1+25+2=28частей

56кг÷28=2кг 1 часть

2×25=50кг глина

2×2=4кг песку

2кг гипс

Answer 2

To calculate the quantities of clay, gypsum, and sand needed to make 56kg of porcelain, we can use the given ratios. Let's break down the problem step by step:

1. The ratio of gypsum to clay is 1:25 in terms of mass. 2. The ratio of sand to gypsum is 2:1 in terms of mass.

To find the quantities of each material needed, we can set up a system of equations:

Let's assume the mass of gypsum is x kg. Then, the mass of clay would be 25x kg (since the ratio of gypsum to clay is 1:25).

According to the second ratio, the mass of sand would be (2/1) * x = 2x kg.

The total mass of the three materials should add up to 56kg:

x + 25x + 2x = 56

Simplifying the equation:

28x = 56

Dividing both sides by 28:

x = 2

Now that we have the value of x, we can calculate the quantities of each material:

- Gypsum: x kg = 2 kg - Clay: 25x kg = 25 * 2 kg = 50 kg - Sand: 2x kg = 2 * 2 kg = 4 kg

Therefore, to make 56kg of porcelain, you would need 2kg of gypsum, 50kg of clay, and 4kg of sand.
