Answer 1

А)435*17+3008=74035+3008=77043 б)435*3025=1315875 в) 4288+44675=48966 г) 27* 153*502=4131*502=2 073 762

Answer 2

а) To solve the expression 435•17+3008, we can perform the multiplication and addition in order:

435 • 17 = 7395 7395 + 3008 = 10403

Therefore, 435•17+3008 equals 10,403.

б) To solve the expression 435•(17+3008), we need to first calculate the sum inside the parentheses, and then multiply it by 435:

17 + 3008 = 3025 435 • 3025 = 1,316,875

Therefore, 435•(17+3008) equals 1,316,875.

в) To solve the expression 67•64+89•502, we can calculate the multiplication first and then perform the addition:

67 • 64 = 4288 89 • 502 = 44,778 4288 + 44,778 = 49,066

Therefore, 67•64+89•502 equals 49,066.

г) To solve the expression 27•(64+89)•502, we first calculate the sum inside the parentheses, then perform the multiplication, and finally multiply by 502:

64 + 89 = 153 27 • 153 = 4,131 4,131 • 502 = 2,076,462

Therefore, 27•(64+89)•502 equals 2,076,462.

In the problem about the angles, the given angles MON, NOA, and AOB are specified as 75°, 105°, and 75°, respectively.

Two angles are said to be supplementary or complementary if their sum is 180°.

Let's calculate the sum of the angles MON and NOA: 75° + 105° = 180°

Since the sum of MON and NOA is 180°, they can be considered supplementary angles.

Now, let's calculate the sum of the angles MON and AOB: 75° + 75° = 150°

Since the sum of MON and AOB is not 180°, they cannot be considered supplementary angles.

Therefore, the pair of rays OM and OA can be supplementary, but the pair of rays OM and OB cannot be supplementary.
