t_f = 1.80(t_c) + 32. therefore, -40°c {negative 40°c} when expressed in fahrenheit scale will be equal to: 1) -40 °f 2) -8 °f 3) -72 °f 4) -2.25 °f
Answer
Explanation:
Step1: Identify the formula and given value
We have the formula for converting Celsius to Fahrenheit: ( T_F = 1.80(T_C) + 32 ), and ( T_C = -40^\circ \text{C} ).
Step2: Substitute the value of ( T_C ) into the formula
Substitute ( T_C = -40 ) into ( T_F = 1.80(T_C) + 32 ). So we get ( T_F = 1.80\times(-40) + 32 ).
Step3: Calculate the multiplication part
First, calculate ( 1.80\times(-40) ). ( 1.80\times(-40)= - 72 ).
Step4: Calculate the final value of ( T_F )
Now, add 32 to -72: ( T_F=-72 + 32=-40 ).
Answer:
- (-40^\circ \text{F})
