Б) 4год44хв

Answer 2

Відповідь:

Покрокове пояснення: а) = 7 м 120 см = 8м 20 см

Б) = 11 год 76 хв - 7 год 32 хв  = 4 год 44 хв

Answer 3

А) To add these lengths, we need to convert the measurements to a common unit. Let's convert everything to centimeters:

4m 73cm = (4 * 100) + 73 = 400 + 73 = 473 cm 3m 47cm = (3 * 100) + 47 = 300 + 47 = 347 cm

Now, we can add them: 473 cm + 347 cm = 820 cm

Therefore, 4m 73cm + 3m 47cm is equal to 820 cm.

Б) To subtract these times, let's first convert everything to minutes:

12 years 16 minutes = (12 * 365 * 24 * 60) + (16) = 6,307,200 minutes + 16 minutes = 6,307,216 minutes 7 years 32 minutes = (7 * 365 * 24 * 60) + (32) = 3,675,120 minutes + 32 minutes = 3,675,152 minutes

Now, we can subtract them: 6,307,216 minutes - 3,675,152 minutes = 2,632,064 minutes

Therefore, 12 years 16 minutes - 7 years 32 minutes is equal to 2,632,064 minutes.
