35км451м+17км682м=? 41т748г-26т749г=? Вычислить Уравнение:481+в=600 481-с =600 Периметр квардата36см.Найди его площадь?

Answer 1

1) 35км 451м + 17км 682м = 53км 122м

2) 41т 748г + 26т 749г = 67т 1кг 497г

3) 481+В=600

   В=600-481

   В=119

4) 481-С=600

   С=600+481

   С=1081

5) Р=4*а - периметр квадрата;

    36:4= 9 - сторона квадрата (а)

   S=a*a - площадь квадрата;    S=9*9=81 см²

Answer 2

To solve the given problems, let's go step by step:

1. Addition and Subtraction of Lengths: a. 35 km 451 m + 17 km 682 m To add these two lengths, we need to ensure that the units are the same. We convert 35 km to meters by multiplying by 1000 (1 km = 1000 m): 35 km = 35,000 m Now, we can add the lengths: 35,000 m + 451 m + 17,682 m = 53,133 m

   b. 41 t 748 g - 26 t 749 g Since the units are the same (grams), we can directly subtract the numbers: 41,748 g - 26,749 g = 14,999 g

2. Solving Equations: a. 481 + v = 600 To find the value of "v," we need to isolate it on one side of the equation. We can do this by subtracting 481 from both sides: v = 600 - 481 v = 119

   b. 481 - c = 600 To find the value of "c," we again need to isolate it on one side of the equation. This time, we need to subtract 481 from both sides, but keep in mind that we want to isolate "c," not "-c": c = 481 - 600 c = -119

3. Finding the Area of a Square: If the perimeter of a square is 36 cm, it means that the sum of all four sides is 36 cm. Since a square has equal sides, we can find the length of one side by dividing the perimeter by 4: Length of one side = 36 cm / 4 = 9 cm

   Now, to find the area of the square, we square the length of one side: Area = (Side length)² = 9 cm × 9 cm = 81 cm²

So, the solutions are:

1. 35 km 451 m + 17 km 682 m = 53,133 meters
2. 41 t 748 g - 26 t 749 g = 14,999 grams
3. a. v = 119 b. c = -119
4. The area of the square is 81 square centimeters.
