Let's solve the provided mathematical expressions step by step.
### Вариант 1
1. **Expression:**
\( 18.25 - (9 - 3:7 \cdot (+ \frac{1}{2} + 30)) \)
First, we evaluate \( 3:7 \):
\( 3:7 \) means \( \frac{3}{7} \).
Next, solve \( +\frac{1}{2} + 30 \):
\( \frac{1}{2} + 30 = 30.5 \).
Now compute \( 3:7 \cdot 30.5 \):
\( \frac{3}{7} \cdot 30.5 = \frac{3 \cdot 30.5}{7} = \frac{91.5}{7} = 13.07142857 \) (approximately).
Then, substitute into the main expression:
\( 18.25 - (9 - 13.07142857) = 18.25 - (-4.07142857) = 18.25 + 4.07142857 = 22.32142857 \) (approximately).
2. **Expression:**
\( \frac{(102 + 18 \cdot 36) \cdot (5 \cdot 37 + 755)}{141} - 4000 \)
Compute \( 18 \cdot 36 = 648 \).
So \( 102 + 648 = 750 \).
Next, compute \( 5 \cdot 37 = 185 \).
Thus, \( 185 + 755 = 940 \).
Now, substitute these into the expression:
\( \frac{750 \cdot 940}{141} - 4000 \).
Calculate \( 750 \cdot 940 = 705000 \).
Next, divide by 141:
\( \frac{705000}{141} \approx 4992.92 \).
Finally, \( 4992.92 - 4000 \approx 992.92 \).
### Вариант 2
1. **Expression:**
\( \frac{(247:8 - 15:7)}{9} - 1\)
Evaluate \( 247:8 = 30.875 \) and \( 15:7 \approx 2.142857 \).
Now simplifying:
\( 30.875 - 2.142857 \approx 28.732143 \).
Now divide by 9:
\( \frac{28.732143}{9} \approx 3.1924 \).
Finally, subtract 1:
\( 3.1924 - 1 \approx 2.1924 \).
2. **Expression:**
\( 16 - 62 \)
Direct computation gives:
\( 16 - 62 = -46 \).
3. **Expression:**
\( \frac{(365:12 - 20:73)}{3} \)
Calculate:
\( 365:12 \approx 30.41667 \) and \( 20:73 \approx 0.27397\).
Therefore,
\( 30.41667 - 0.27397 \approx 30.1427 \).
Now divide by 3:
\( \frac{30.1427}{3} \approx 10.04757 \).
4. **Expression:**
\( 10 \cdot (48g:12 - 20:63) - 1g0 \)
This seems to contain "g" as a variable. Please clarify what "g" refers to.
5. **Expression:**
\( (8 \frac{2}{3} + 5 \cdot 1k - 10:23): (82 - 53) \)
Evaluate:
Compute \( 82 - 53 = 29 \).
Need clarification on "k", then compute the whole expression.
### Вариант 3
1. **Expression:**
\( \frac{5.632:0.11 + 4.256:1.12 - (52.4 + 0.39:0.15)}{1} \)
This requires calculations for division and subtraction.
Compute \( 5.632:0.11 = 51.1 \) and \( 4.256:1.12 = 3.8 \).
Now compute \( 0.39:0.15 \approx 2.6 \).
Final result from this, please clarify if each value needed or just the overall answer.
2. **Expression:**
\( \frac{(10 \frac{2}{3} - 0.405 + k \cdot 22)}{5.51} + 2 - 4.5\)
Same rule, calculate stepwise and indicate clear components for "k".
3. **Expression:**
\( (20.3 - 18.13) \cdot 4.3 + \frac{(0.1614 + 0.5421)}{0.67} \)
Needs detail to compute component parts.
4. **Expression:**
\( 0.9:3 + 17.85:3 - (5 \frac{2}{3} - 3k) - 63 \)
Likewise demands breakdown for all calculations.
### Вариант 4
1. **Expression:**
\( \frac{(x + 0.4 + 0.3 \cdot 5)}{75} \)
Ensure values for each parameter.
2. **Expression:**
\( \frac{(125 - 64 + 128 \cdot 75)}{800 \cdot 5000} - (300 - 400 + 5107 \cdot 800): 70 \)
Further breakdown from the above.
3. **Expression:**
\( \frac{2.6 + \frac{4 \frac{2}{3} + 0.15}{3}}{1} \)
Refine based on component values.
Please provide clarification on any ambiguous sections, notably parameters associated with each mathematical variable like “g”, “k”, or terms that seem unspecified.
