1. Write the number that stands for 5 tens, 7 hundreds, 3 thousands, 7 ten thousands: - 5 tens = $5 \times 10 = 50$ - 7 hundreds = $7 \times 100 = 700$ - 3 thousands = $3 \times 1000 = 3000$ - 7 ten thousands = $7 \times 10000 = 70000$ - Total number = $70000 + 3000 + 700 + 50 = 73750$ 2. Calculate the number of thousands in one-half of a million: - One million = $1,000,000$ - Half a million = $\frac{1,000,000}{2} = 500,000$ - Number of thousands in $500,000$ is $\frac{500,000}{1000} = 500$ 3. Approximate $5164$ to the nearest hundred dollars: - Look at the tens digit (6), which is $\geq 5$ so round up - Rounded value = $5200$ 4. Write the largest numeral using digits 4, 3, 7, and 1 once only: - Arrange digits in descending order: $7, 4, 3, 1$ - Largest numeral = $7431$ 5. Calculate the number that is eighteen less than ten thousand and one: - Ten thousand and one = $10001$ - Subtract $18$: $10001 - 18 = 9983$ 6. Calculate the difference in value between the circled digits in $1249326$: - Without explicitly knowing the circled digits, let's assume example digits; since no digits specified, we cannot answer precisely. 7. Approximate $586.40$ to the nearest hundred dollars: - Tens digit is 8 ($\geq 5$), round up - Rounded value = $600$ "content":"1.
