Kareem heats a beaker of water to a boil. Then he records that the water temperature decreases from 100°C to 19°C in 5 2/5 minutes. What was the change in temperature each minute? Enter your answer in the box.

Step-by-step explanation:

In this problem, we are expected to solve for the rate of change of the temperature per minute.

Given data

initial temperature= 100°C

final temperature=  19°C

Time taken  for the change to occur= 5 2/5 minutes to proper fraction we have 27/5 min

Now we can calculate the change in temperature as = 100-19= 81°C

therefore the rate of change in temperature per minute is

rate= 81/27/5

Take the reciprocal of the denominator we have

rate= (81*5)/27

rate= 405/27

rate= 15°C/min

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
