How many 5-digit palindromes contain only even digits?
34kurt

Answer:

The correct answer is - 900

Step-by-step explanation:

A palindrome is a positive integer that is same whether read from left to right or from right to left. For example, 123321 palindromes.

An n-digit palindrome is determined from the first  n/2  digits if n is even, and from the first n+1/2 digits if n is odd.

Therefore, if  n  is even, there are  9×10⁽n⁻²/²⁾  palindromes; and if n is odd, there are  9×10⁽n₋²/²⁾ palindromes.  where n is number of digits.

For  n=5 , there are  9×10²=900 palindromes

A regular hexagon has an apothem of 14. 7 inches and a perimeter of 101. 8 inches. What is the area of the hexagon?.
AleksAgata [21]

Answer:

748.23 in²

Step-by-step explanation:

<u>Area of a Regular Polygon</u>

\textsf{Area of a regular polygon}=\dfrac{n\:l\:a}{2}

where:

  • n = number of sides
  • l = length of one side
  • a = apothem

Given:

  • n = 6
  • l = 101.8 ÷ 6
  • a = 14.7

Substituting the given values into the formula and solving for A:

\implies \textsf{A}=\dfrac{6 \cdot \dfrac{101.8}{6} \cdot 14.7}{2}

\implies \sf A=\dfrac{101.8 \cdot 14.7}{2}

\implies \sf A=\dfrac{1496.46}{2}

\implies \sf A=748.23

Therefore, the area of the hexagon is 748.23 in²
