9 is D and 10 is B. Take the slope of the point you are trying to move, and go to the counter clockwise axis. Do the slope but in its reciprocal form. If you sketch out the answers I’ve given, it should help visualize the method.

Vladimir79 [104]

Answer: 1512°C

Step-by-step explanation:

I will answer this in English:

The data we have: The boiling point is 2595°C and the fussion point is 1083°C

the difference between those points is equal to the direct difference between the temperatures:

Diff = 2595°C - 1083°C = 1512°C

The formula used to convert degrees Celsius to degrees Fahrenheit is

bonufazy [111]

The formula to convert degrees Fahrenheit to Celsius is:

$\bf{^{\circ}C=\dfrac{5}{9}(^{\circ}F-32) \ \ \to \ \ \ Formula }$

Convert 59°F to degrees Celsius.

Add the number 59 in the formula, and solve.

$\bf{=\dfrac{5}{9}(59-32) }$

Subtract 32 from 59.

$\bf{=\dfrac{5}{9}(27) }$

Multiply 5 x 9 = 135, then divide 135/9 = 15.

$\bf{=15 \ ^{\circ}C}$

Therefore 59 °F = 15 °C. The correct option is "D".
