Answer:
- If a group of 9 kids have won a total of 100 trophies, then at least one of the 9 kids has won at least 12 trophies.
- If a person buys at least 400 cups of coffee in a year, then there is at least one day in which the person has bought at least two cups of coffee.
- The average of three real numbers is greater than or equal to at least one of the numbers.
Explanation:
1)
Suppose that each kid has less than 12 trophies
Total trophies = 100
Maximum trophies won by one kid = 11
total kids = 9
total number of trophies = 9 * 11 = 99 which contradicts the fact the total number of trophies are 100
2)
Suppose that person has less than 2 cups of coffee a day
Total cups of coffee = 400
he has bought at least one cup of coffee each day
which means
total number of cups of coffee = 1* 366 = 366 which contradicts the fact the person buys at least 400 cups of coffee in a year
3)
Average of three number = (a+ b+ c)/3
suppose that there are real numbers a, b, and c such that all three numbers are less than the average of the three numbers.
Let m be the average (a+b+c
)/3 = m. Then our assumption states that (a < m) and (b < m) and (c < m). By adding all the inequalities we get a + b + c < 3m. But m is defined to be (a+b+c)
/3 , so a + b + c = 3m. But now we have that 3m = a + b + c < 3m. So 3m < 3m which is an obvious contradiction. Thus our claim is true

Answer:
<u>Pseudocode:</u>
INPUT velocity
INPUT time
SET velocity = 0.44704 * velocity
SET acceleration = velocity / time
SET acceleration = round(acceleration, 1)
PRINT acceleration
<u>Code:</u>
velocity = float(input("Enter a velocity in miles per hour: "))
time = float(input("Enter a time in seconds: "))
velocity = 0.44704 * velocity
acceleration = velocity / time
acceleration = round(acceleration, 1)
print("The acceleration is {:.2f}".format(acceleration))
Explanation:
*The code is in Python.
Ask the user to enter the velocity and time
Convert the miles per hour to meters per second
Calculate the acceleration using the formula
Round the acceleration to one decimal using round() method
Print the acceleration with two decimal digits
