`F=(9//5)C+32` is the linear equation that converts Celsius(C) to Fahrenheit (F).
(i) if the temperature is `35^(@)` then what is the temperature in fahrenheit (ii) if the temperature is `30^(@)` C then what is the temperature in fahrenheit

Answer

To solve the problem of converting Celsius to Fahrenheit using the equation \( F = \frac{9}{5}C + 32 \), we will follow these steps for each part of the question.

### Part (i): Convert 35°C to Fahrenheit

1. **Identify the given value**:
- We have \( C = 35 \) degrees Celsius.

2. **Substitute the value into the equation**:
- Use the formula \( F = \frac{9}{5}C + 32 \).
- Substitute \( C \) with 35:
\[ F = \frac{9}{5} \times 35 + 32 \]

3. **Calculate \( \frac{9}{5} \times 35 \)**:
- First, simplify \( \frac{9}{5} \times 35 \):
\[ \frac{9 \times 35}{5} = \frac{315}{5} = 63 \]

4. **Add 32 to the result**:
- Now, add 32 to 63:
\[ F = 63 + 32 = 95 \]

5. **Final result**:
- Therefore, when \( C = 35 \) degrees Celsius, \( F = 95 \) degrees Fahrenheit.

### Part (ii): Convert 30°C to Fahrenheit

1. **Identify the given value**:
- We have \( C = 30 \) degrees Celsius.

2. **Substitute the value into the equation**:
- Use the formula \( F = \frac{9}{5}C + 32 \).
- Substitute \( C \) with 30:
\[ F = \frac{9}{5} \times 30 + 32 \]

3. **Calculate \( \frac{9}{5} \times 30 \)**:
- First, simplify \( \frac{9}{5} \times 30 \):
\[ \frac{9 \times 30}{5} = \frac{270}{5} = 54 \]

4. **Add 32 to the result**:
- Now, add 32 to 54:
\[ F = 54 + 32 = 86 \]

5. **Final result**:
- Therefore, when \( C = 30 \) degrees Celsius, \( F = 86 \) degrees Fahrenheit.

### Summary of Results:
- (i) 35°C = 95°F
- (ii) 30°C = 86°F
