You place a cup of 200°F coffee on a table in a room that is 67°F, and 10
minutes later, it is 195°F. Approximately how long will it be before the coffee
is 180°F? Use Newton's law of cooling:
T(t) =TA +(T.-T )e-kt
O A. 43 minutes
OB. 1 hour
O
C. 15 minutes
O
D. 35 minutes

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

b. b < 1 might be the correct answer
