To make a potato salad, a chef cooked some unpeeled potatoes inboiling water at 100°C. Once the potatoes have been cooked throughand drained, he sets them aside, uncovered, in a room at 28°C. Twominutes later, he picks up a potato to start peeling, but to his horror,the potato is still 85°C - much too hot to work with. He knows thatthe potato must at least be within 10°C of his body temperature (37C) before he could start peeling them safely.At least how many minutes should the chef let the potato cool beforehe can start to peel?O 11.4 minutesO 9.2 minutesO 17.8 minutesO 14.6 minutes

The correct answer is option (A) i.e. t = 11.4 minutes

Alice is hosting her extended family for Christmas lunch, so she is busy cooking on Christmas Eve. She wants to get to bed though as she knows Christmas day will be busy! The pot of soup has finally boiled (at 100°C), but Alice is concerned about putting hot food straight in the fridge. She decides to cool the pot off in a sink full of cold water (at 5°C). This table shows the temperature of the soup over a period of 75 minutes. 0 100 5 83.56266539 10 69.96939362 15 58.72809191 20 49.43181166 25 41.74401634 30 35.38639853 35 30.12880485 40 25.78090407 45 22.18529698 50 19.21181828 55 16.75282447 60 14.71929701 65 13.03761978 70 11.64691403 75 10.49683456 1.

In a tank containing 200 liters of freshwater, 50 kg of salt is poured instead of 40kg. To correct this condition, 10 liters of brine are allowed to flow out per minute while 10 liters of fresh water per minute are pumped into the tank. If the mixture is kept uniform by stirring, find the time required for the tank to contain the desired amount of salt.
A student is concerned with the amount of air pollution students are exposed to in the school's parking lot after school. The student conducts an investigation to compare the quantity of particulate matter released from the diesel-powered buses, natural gas-powered buses, and the large and small cars as they idle waiting to pick up students. To make measurements, a small piece of white fabric is used to collect particulate matter from the tailpipe of each vehicle as it idles for five minutes. Each piece of fabric is then analyzed to measure the amount of particulate matter it collected. (i) Identify the independent variable in the investigation. (j) Identify one variable that was not mentioned in the description that could affect the results of the investigation. (k) Describe a realistic alternate sampling method to collect particulate matter from the vehicles in the investigation. (1) The student wants to ensure that the results are reliable. Explain how the student could modify the…
Suppose that a commercial bakery produces chocolate chip cookies. Based on extensive testing, the bakery has determined that the ideal number of chocolate chips per cookie is 18. In the past, master bakers mixed the dough and spooned it onto sheet pans by hand, but the owners have decided to test a new machine. The machine extrudes dough onto baking sheets at a uniform rate. It runs continuously from 4:30 a.m. until 12:30 p.m. The number of chips per cookie depends on the viscosity of the dough, and because the dough stiffens as it sits in the machine, the machine produces cookies that contain the optimal number of chips, 18 per cookie, between the hours of 5:00 a.m. and 11 a.m. The distribution of cookies is shown in the graph below. The shaded area represents the proportion of all cookies that contain exactly 18 chocolate chips. 4:00 5:00 6:00 7:00 8:00 9:00 10:00 11:00 12:00 1:00 Compute the proportion of cookies produced each day that contain the optimal number of chocolate chips.…
