To convert the temperature from Celsius to Fahrenheit, we use the formula:
[tex]\[ T_{\left(^{\circ}F\right)} = \frac{9}{5} \times T_{\left(^{\circ}C\right)} + 32 \][/tex]
Given that the temperature on Jessica's patio is [tex]\( 18^{\circ}C \)[/tex], we can substitute this value into the formula:
[tex]\[ T_{\left(^{\circ}F\right)} = \frac{9}{5} \times 18 + 32 \][/tex]
First, we need to calculate the product [tex]\(\frac{9}{5} \times 18\)[/tex]:
[tex]\[ \frac{9}{5} \times 18 = 32.4 \][/tex]
Next, we add 32 to this result:
[tex]\[ 32.4 + 32 = 64.4 \][/tex]
Thus, the temperature on Jessica's patio in Fahrenheit is [tex]\( 64.4^{\circ}F \)[/tex].
