Question

Найди значение выражений: 1) 3070*64+(20000-171360:56) 2) 8км 200м-4км:80 3) 1мин:12 4) 4м 7дм+363см Решите пожалуйста по действиям.

Answer 1

Ответ:

Пошаговое объяснение:

1) 171360:56=3060

  20000-3060=16940

  3070*64=196480

   196480+16940=213420

2) 4:80=0.05км= 50м

   8км 200м-50м=8км 150м = 8.150 км

3) 1минута=60секунд

   60:12=5секунд

4) 4м 7дм= 470см

   470см+363см=833см

Answer 3

Вычисления математических выражений:

1) 3070*64 + (20000-171360/56)

To solve this expression, we can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

First, let's solve the expression inside the parentheses: 20000 - 171360 ÷ 56 = 20000 - 3060 = 16940

Now, we can calculate the entire expression: 3070 * 64 + 16940 = 196480 + 16940 = 213420

Answer: 213420

2) 8км 200м - 4км ÷ 80

To solve this expression, we need to convert all measurements to the same unit (meters) before performing the subtraction.

8 km = 8000 m 200 m = 200 m 4 km = 4000 m

Now, we can calculate the entire expression: 8000 m + 200 m - 4000 m ÷ 80 = 8200 m - 50 m = 8150 m

Answer: 8150 m

3) 1мин ÷ 12

This expression represents the division of 1 minute by 12. The result is:

1 minute ÷ 12 = 1/12 minutes

Answer: 1/12 minutes

4) 4м 7дм 363см

To solve this expression, we can convert all measurements to the same unit (centimeters) and then add them together.

4 m = 400 cm 7 dm = 70 cm 363 cm = 363 cm

Now, we can calculate the entire expression: 400 cm + 70 cm + 363 cm = 833 cm

Answer: 833 cm
