1. The problem asks to identify the Mayan symbol for the base-10 number 3457. 2. The Mayan numeral system is vigesimal (base-20), not base-10. To find the Mayan symbol for 3457, we must convert 3457 from base-10 to base-20. 3. Conversion steps: - Divide 3457 by 20: $$3457 \div 20 = 172 \text{ remainder } 17$$ - Divide 172 by 20: $$172 \div 20 = 8 \text{ remainder } 12$$ - Divide 8 by 20: $$8 \div 20 = 0 \text{ remainder } 8$$ 4. So, 3457 in base-20 is represented as digits 8, 12, and 17 from highest to lowest place value. 5. In Mayan numerals: - Dots represent 1 each. - Bars represent 5 each. - The eye-like symbol represents zero. 6. To represent each digit: - 8 = 1 bar (5) + 3 dots (3) - 12 = 2 bars (10) + 2 dots (2) - 17 = 3 bars (15) + 2 dots (2) 7. The Mayan number is written vertically with the highest place value at the top: - Top level: 8 - Middle level: 12 - Bottom level: 17 8. The correct Mayan symbol for 3457 is the one with these three levels matching the above dot and bar counts. Final answer: The last option selected in the graph matches the correct Mayan symbol for 3457.
