At 10: 07 p. m. you find a secret agent murdered. next to her is a martini that got shaken before the secret agent could stir it. the room temperature is 70◦f. the martini warms from 60◦f to 61◦f in the 2 minutes from 10: 07 p. m. to 10: 09 p. m. if the secret agent’s martinis are always served at 40◦f, what was her time of death, to the nearest minute?

Her time of death was 9:27 P.M.

Explanation:

Since the martini warmed from 60°F to 61°F in 2 minutes,

Therefore, it takes 2 minutes for the temperature to rise by 1°F.

At 10:07 P.M. (when the secret agent was found dead), the temperature of the martini was 60°F.

Martini's are served at 40°F.

Temperature change of the martini from when it was served to when the agent was murdered = 60 - 40 =20°F

If 1°F = 2 minutes,

then 20°F = 40 minutes.

40 minutes before 10:07 P.M is 9:27 P.M.

Therefore the agent was murdered around 9.27 P.M.

is this an essay or multiple choice

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
