Dude this is an final exam stupids

Bruh your dummmm

To check if your answers are correct, let's go through each question one by one and explain how to find the correct answer.

1) The length of the room is given as 5.048 × 10^2 cm. To convert this into a number, we move the decimal point two places to the left due to the exponent. So the correct answer is C) 504.8 cm.

2) To find the total amount of all four ingredients, we add the fractions together: 1 1/4 + 3/4 + 1/2 + 1/4. To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 4. So the sum is 5/4 + 3/4 + 2/4 + 1/4 = 11/4. Converting this fraction to a mixed number gives us 2 3/4 cups. So the correct answer is D) 2 3/4 cups.

3) To multiply fractions, we multiply the numerators together and the denominators together. So, 3/4 x 3 = (3 x 3)/(4 x 1) = 9/4. The correct answer is D) 9/4.

4) To find the amount of cooking oil required for 4 batches of cookies, we multiply the amount of oil required for 1 batch (2/3 cup) by 4. So, 2/3 x 4 = 8/3 cups. Converting this fraction to a mixed number gives us 2 2/3 cups. So the correct answer is C) 2 2/3 cups.

5) To find the decimal equivalent of a fraction, divide the numerator by the denominator. So, 5/2 = 2.5. The correct answer is B) 2.5.

6) To find the discount on the CD, multiply the original price ($12.99) by the discount percentage (1/4). So, 1/4 x $12.99 = $3.2475. Rounding this to the nearest cent gives us $3.25. So the correct answer is not listed, but a more accurate estimation would be C) $3.25.

7) An irrational number is a number that cannot be expressed as a fraction or a decimal. The square root of 5 is irrational, so the correct answer is A) √5.

8) Similar to question 7, the square root of 3 is also irrational. So the correct answer is D) √3.

9) To find the final sale price, we first calculate the discounted price after the first 50% off, which is $88 × (1 - 0.5) = $44. Then, we calculate the discounted price after an additional 25% off, which is $44 × (1 - 0.25) = $33. So the correct answer is B) $33.

10) To simplify 5^6 × 5^-2, we can subtract the exponents since we have the same base. 5^6 / 5^2 = 5^(6-2) = 5^4. So the correct answer is C) 5^4.

11) To simplify the fraction, we divide the terms using the same base. 4^2 × 3^5 × 2^4 / 4^3 × 3^5 × 2^2 = 4^(2-3) × 3^(5-5) × 2^(4-2) = 4^-1 × 3^0 × 2^2 = 1/4 × 1 × 4 = 1. So the correct answer is C) 1.

12) To compare the fees for each attorney, we calculate the amount of money Ms. Mandel charges: 1 1/2% of $200,000. To convert the percentage to a fraction, divide by 100: 1 1/2% = 1.5/100 = 0.015. Then, multiply 0.015 by $200,000: 0.015 × $200,000 = $3,000. Comparing the fees, we see that Ms. Mandel charges less than Mr. Gable's flat rate of $2,500. So the correct answer is B) Ms. Mandel.
