1. To calculate the percent of states that will have a Spanish-speaking majority, we need to divide the number of states with a Spanish-speaking majority (20) by the total number of states (50) and then multiply by 100 to get the percentage. So the calculation would be (20/50) * 100 = 40%. Therefore, the correct answer is C. 40%.
2. To find the percent of 25 that is 10, we need to divide 10 by 25 and multiply by 100 to get the percentage. So the calculation would be (10/25) * 100 = 40%. Therefore, the correct answer is A. 10=p*25; 40%.
3. To calculate the sales tax, we need to multiply the purchase amount ($77.00) by the sales tax rate (6.3%). So the calculation would be $77.00 * 0.063 = $4.85. Therefore, the correct answer is C. $4.85.
4. To find the amount of sales tax for a lawnmower that costs $265.00 at a 6% tax rate, we need to multiply the purchase amount ($265.00) by the sales tax rate (6%). So the calculation would be $265.00 * 0.06 = $15.90. Therefore, the correct answer is C. $15.90.
5. To calculate the percent of change in population at Arlington Middle School from 2000 to 2010, we need to find the difference between the two populations, divide that by the initial population, and then multiply by 100 to get the percentage. The calculation would be [(584 - 421) / 421] * 100 = 38.7%. Since the population increased from 2000 to 2010, the correct answer is C. 38.7%; increase.
