Amanda [17]

Answer:

17m

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

The following equation would be used: A=\frac{a+b}{2} h

We would simply substitute the given values, move the values around then we would get our answer:

230.945=18.7\frac{7.7+b}{2}\\\\230.945=9.35(7.7+b)\\\\b+7.7=24.7\\\\b=17m

One fragment of a given integer N can be selected and its digits reversed (replaced with a right to left version of themselves).

Integers are numbers without decimal points. The number could be positive, negative or zero

<h3>How to determine the maximum number from the integer</h3>

The maximum number from integer N can be determined using the following program written in Python, where comments are used to explain each line

#This prompts the user for input

num = input("Number: ")

#This iterates from 0 to 9

kount = [0 for x in range(10)]

# This iterates through the input, and updates the kount variable

for i in range(len(num)):

   kount[int(num[i])] = kount[int(num[i])] + 1

# This next two lines initialize the greatest number

greatestNum = 0

multiplier = 1

# This iterates through the kount array

for i in range(10):

   #The following is repeated while the current element is greater than 0

while kount[i] > 0:

    #This generates the greatest number

 greatestNum = greatestNum + ( i * multiplier )

 kount[i] = kount[i] - 1

 multiplier = multiplier * 10

#This prints the greatest number

print(greatestNum)
