Suppose that a cup of soup cooled from 90 °C to 60 °C after 15 minutes in a room whose temperature was 20 °C. Use Newton's law of cooling to answer the following questions.
(a) How much longer would it take the soup to cool to 45 °C?
(b) Instead of being left to stand in the room, the cup of 90 °C soup is put in the freezer whose temperature is - 15 °C. How long will it take the soup to cool from 90 °C to 45 °C?

d i think

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
