Answer 3

Let's solve the given expressions step by step:

1. (-41:0.25 + 162.8) : (-0.06)

First, let's simplify the division inside the parentheses: -41 divided by 0.25 = -164

Now we can substitute this value into the expression: (-164 + 162.8) : (-0.06)

Next, we simplify the addition inside the parentheses: -164 + 162.8 = -1.2

Now we have: -1.2 : (-0.06)

Finally, we can perform the division: -1.2 divided by -0.06 = 20

Therefore, the value of the expression is 20.

2. (-20.5) × (1821 - 73:0.04)

First, let's simplify the division inside the parentheses: 73 divided by 0.04 = 1825

Now we can substitute this value into the expression: (-20.5) × (1821 - 1825)

Next, we simplify the subtraction inside the parentheses: 1821 - 1825 = -4

Now we have: (-20.5) × (-4)

Finally, we can perform the multiplication: -20.5 multiplied by -4 = 82

Therefore, the value of the expression is 82.

To summarize:

1. (-41:0.25 + 162.8) : (-0.06) = 20
2. (-20.5) × (1821 - 73:0.04) = 82
