(1) Farmer Ben has only ducks and cows 21 in total. He can’t remember how many of each he has. He knows
gavmur [86]

Answer:

Answer of question 1 :

Explanation:

Let x be the legs of ducks

And y be the legs of cows

According to the question,

2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)

As he has 21 animals in total so,

x + y = 21...…..(ii)

We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.

From equation (ii)

x = 21 - y....…..(iii)

Putting the value of x in equation (i),

2x + 4y = 52

2( 21 - y ) + 4y = 52

42 - 2y + 4y = 52

2y = 52 - 42

y = 10/2

y = 5 ( He has 2 cows)

putting the value of y in equation (ii)

x + y = 21

x + 5 = 21

x = 21 -5

x = 16 ( He has 16 ducks)

The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journa
Misha Larkins [42]

The program is an illustration of a sequential structure

<h3>What are sequential control structures?</h3>

Sequential control structures are programs that do not require loops and conditional statements

<h3>The actual program</h3>

The program in Python where comments are used to explain each line, is as follows:

#This gets input for age

age = int(input("Age: "))

#This gets input for weight

weight = (input("Weight: "))

#This gets input for the heart rate

heartRate = float(input("Heart Rate: "))

#This gets input for the time

time = int(input("Time: "))

#This calculates the calories burnt

calories = ((age * 0.2757) + (weight * 0.03295) + (heartRate * 1.0781) - 75.4991 ) * time / 8.368

#This prints the calories burnt

print('calories: {:. 2f} calories'. Format(calories))
