the graph shows the realationship between temperature in degrees celsius and in degrees fahrenhiet. mark the point on the graph that shows the temature in celsius when it is 60 degrees Fahrenheit. then make point on the graph that shows the temperature is Fahrenheit when it is 60 degrees celsius. would 100 degrees Fahrenheit give you 40 degrees celsius, why or why not?

To approach this problem, we will use the conversion formula between Celsius (\( C \)) and Fahrenheit (\( F \)):

\[
F = \frac{9}{5}C + 32
\]

### Step 1: Find the Celsius equivalent when \( F = 60 \).
Using the formula, we solve for \( C \) when \( F = 60 \):

\[
60 = \frac{9}{5}C + 32
\]

Subtract 32 from both sides:

\[
60 - 32 = \frac{9}{5}C
\]

\[
28 = \frac{9}{5}C
\]

Now, multiply both sides by \( \frac{5}{9} \) to solve for \( C \):

\[
C = 28 \times \frac{5}{9} = \frac{140}{9} \approx 15.56^\circ \text{C}
\]

So, when it is 60°F, the Celsius temperature is approximately \( 15.56^\circ C \). You can plot this point as (60, 15.56) on the graph.

### Step 2: Find the Fahrenheit equivalent when \( C = 60 \).
Now, use the formula again to find \( F \) when \( C = 60 \):

\[
F = \frac{9}{5} \times 60 + 32 = 108 + 32 = 140^\circ F
\]

So, when it is 60°C, the Fahrenheit temperature is \( 140^\circ F \). You can plot this point as (140, 60) on the graph.

### Step 3: Would 100 degrees Fahrenheit give 40 degrees Celsius?

Let's check by solving for \( C \) when \( F = 100 \):

\[
100 = \frac{9}{5}C + 32
\]

Subtract 32 from both sides:

\[
100 - 32 = \frac{9}{5}C
\]

\[
68 = \frac{9}{5}C
\]

Multiply by \( \frac{5}{9} \) to solve for \( C \):

\[
C = 68 \times \frac{5}{9} = \frac{340}{9} \approx 37.78^\circ C
\]

So, 100°F corresponds to approximately \( 37.78^\circ C \), **not exactly 40°C**. This is because the conversion between Fahrenheit and Celsius follows a precise formula, and the values do not align exactly at 100°F and 40°C.
