Complete the function definition to return the hours given minutes. Sample output with input: 210.0 3.5

kodGreya [7K]

The complete function definition to output the hours given minutes is as follows:

def output_minutes_as_hours(orig_minutes):

return f"{orig_minutes / 60 } hours"

print(output_minutes_as_hours(120))

<h3>How to complete programming in Python?</h3>

The code is written in python.

Firstly, we define a function named "output_minutes_as_hours" and the function accept an argument "orig_minutes". The argument is the time in minutes.

Then, we return answer in hours when we divide the orig_minutes by 60.

Finally, we call the function along with it parameter.

The complete question is;

A high school track coach has just purchased a new stopwatch that has an uncertainty of s. runners on the team regularly complet

Alexeev081 [22]

A high school track coach has just purchased a new stopwatch. The stopwatch manual states that the stopwatch has an uncertainty of ±0.05 s . Runners on the track coach’s team regularly clock 100-m sprints of 11.49 s to 15.01 s . At the school’s last track meet, the first-place sprinter came in at 12.04 s and the second-place sprinter came in at 12.07 s .

No, the new stop watch will not be effective in timing the sprint team. The reason for the same is that the uncertainty in the stopwatch is too small to effectively differentiate between the sprint times.

If sprinters were timed with the new stopwatch, first sprinter's time would have been between = 12.04 - 0.05 and 12.04 + 0.05

= 11.99 and 12.09

or between the interval [11.99 , 12.09]

while the second sprinter's time would have been between

= 12.07 - 0.05 =and 12.07 + 0.05

= 12.02 and 12.12

or between the interval [12.0.2 , 12.12]

Hence, there is an overlap between the worst time of the first sprinter, that is, 11.99 and the best time of the second sprinter, that is, 12.02

If 50. 0 g of ch₃oh (mm = 32. 04 g/mol) are added to a 500. 0 ml volumetric flask, and water is added to fill the flask, what is

Elza [17]

Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 $\frac{moles}{liters}$ .

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

$Molarity=\frac{number of moles}{volume}$

Molarity is expressed in units $\frac{moles}{liters}$ .

<h3>Concentration of CH₃OH</h3>

In this case, you know:

number of moles= 50 g× $\frac{1 mole}{32.04 g}$ = 1.56 moles, being 32.04 $\frac{g}{mole}$ the molar mass of CH₃OH
volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
