a. 3.75
b. 3.25
c. 3.15
d. 3.5

Option B 3.25

Step-by-step explanation:

Troy worked for 3 hours and 15 minutes.

Since the timing on the card should be  written on the card in terms of hours.

For which we will convert the time 3 hours 15 minutes into hours.

3 hours  15 minutes =  3 hours + 15 minutes

= 3 hours + hours

= 3.25 hours.

Option B 3.25 hours will be the answer.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
