Answer 2

Calculations:

To calculate the given expression, let's break it down step by step:

1. 15372 + 26520:34 + 30 + 429 + 43 + 113680:28 + 3: - First, perform the division: 26520 divided by 34 equals 780. - Then, perform the division: 113680 divided by 28 equals 4057. - Now, the expression becomes: 15372 + 780 + 30 + 429 + 43 + 4057 + 3. - Adding all the numbers together, the result is: 20414.

2. 5т 84 ц = 40 000 мм2 = ... см2: - To convert from square millimeters (мм2) to square centimeters (см2), we need to divide by 100. - Therefore, 40,000 мм2 is equal to 400 см2.

3. 3 кг 80 г = 2 ч 10 мин = ... сек столбиком: - To convert from kilograms (кг) to grams (г), we need to multiply by 1000. - Therefore, 3 кг 80 г is equal to 3,080 г. - To convert from hours (ч) to minutes (мин), we need to multiply by 60. - Therefore, 2 ч 10 мин is equal to 130 мин. - To convert from minutes (мин) to seconds (сек), we need to multiply by 60. - Therefore, 130 мин is equal to 7,800 сек.

4. 76 900 54 237 74 27 846 + 13 358 + ... Г КГ: - The given expression is incomplete, so it is not possible to calculate the result without the missing value.

Geometry:

To solve the geometry problem, let's follow the steps:

1. Nачерти квадрат с периметром 24 см: - A square with a perimeter of 24 cm means that all sides of the square are equal. - To find the length of each side, divide the perimeter by 4: 24 cm ÷ 4 = 6 cm. - Therefore, the square has sides of length 6 cm.

2. Вычисли площадь квадрата: - The area of a square is calculated by multiplying the length of one side by itself. - In this case, the length of one side is 6 cm. - Therefore, the area of the square is 6 cm × 6 cm = 36 cm2.

3. Заштрихуй 2/4 его: - To shade 2/4 of the square, divide the square into four equal parts. - Shade two of those parts. - The shaded area represents 2/4 or 1/2 of the total area of the square.
