Answer 1

350 - (350/5) = 350 - 70 = 280 кг.

Answer 2

350/5*4=280 кг масса після сушіння

Answer 3

Calculation of the Weight of Bricks After Drying and Firing

The weight of the bricks after drying and firing can be calculated using the initial weight and the percentage decrease in weight.

Initial Weight of Bricks: 350 kg Percentage Decrease in Weight: 1/5 (or 20%)

To calculate the weight of the bricks after drying and firing, we can use the following formula:

Weight after Drying and Firing = Initial Weight - (Percentage Decrease * Initial Weight)

Substituting the given values: Weight after Drying and Firing = 350 kg - (1/5 * 350 kg)

Calculating the result: Weight after Drying and Firing = 350 kg - 70 kg Weight after Drying and Firing = 280 kg

Therefore, the weight of the bricks after drying and firing is 280 kg.
