Answer 1

1)100-90=10(%)- Никеля в сплаве
2)51х0,9=45,9 (кг) -Железа
3)51х0,1=5.1 (кг ) -Никеля
Ответ? 5.1

Answer 2

Calculating the Composition of the Alloy

To calculate the amount of iron and nickel in the alloy, we can use the given information that iron makes up 90% of the alloy, with the rest being nickel. The total mass of the alloy is 51 kg.

Step 1: Calculate the Amount of Iron in the Alloy The amount of iron in the alloy can be calculated as 90% of the total mass of the alloy.

Step 2: Calculate the Amount of Nickel in the Alloy The amount of nickel in the alloy can be calculated as 10% of the total mass of the alloy.

Calculation

Step 1: Amount of Iron 90% of 51 kg = 0.90 * 51 kg = 45.9 kg

Step 2: Amount of Nickel 10% of 51 kg = 0.10 * 51 kg = 5.1 kg

Therefore, the alloy contains approximately 45.9 kg of iron and 5.1 kg of nickel.
