What is the smallest number with distinct digits whose digits add up to 45?
Show Hint
- 123555789
- 123457869
- 123456789
- 99999
The Correct Option is C
Solution and Explanation
\[ 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45. \]
Step 2: Therefore, the number must use all digits from 1 to 9 exactly once.
Step 3: To get the smallest number, arrange these digits in ascending order: \(123456789\).
Final Answer: \(\boxed{123456789}\).

A regular dodecagon (12-sided regular polygon) is inscribed in a circle of radius \( r \) cm as shown in the figure. The side of the dodecagon is \( d \) cm. All the triangles (numbered 1 to 12 in the figure) are used to form squares of side \( r \) cm, and each numbered triangle is used only once to form a square. The number of squares that can be formed and the number of triangles required to form each square, respectively, are:
