The image you provided shows a Mayan numeral, which you need to convert to a base-10 number.

In Mayan numerals:
- A dot represents 1.
- A horizontal bar represents 5.
- A shell (though not present in this image) represents 0.

The system is vigesimal (base-20), meaning each place represents a power of 20. From top to bottom, the place values are \(20^2\), \(20^1\), and \(20^0\) (i.e., 400, 20, and 1, respectively).

### Let's break down the Mayan numeral:
- Top row: 3 dots = 3 (in the \(20^2 = 400\) place value).
- Middle row: 1 dot above 2 bars = 1 + (2 * 5) = 11 (in the \(20^1 = 20\) place value).
- Bottom row: 1 bar = 5 (in the \(20^0 = 1\) place value).

### Now calculate the base-10 value:
\[
3 \times 400 + 11 \times 20 + 5 \times 1 = 1200 + 220 + 5 = 1425
\]

The equivalent base-10 number is **1425**.
