Final answer:
The amount of beef needed to make 80 meals, given a ratio of 5 pounds of beef for 20 meals, is 20 pounds.
Explanation:
To get an answer to this question, we first need to establish the ratio of beef needed for a single meal. The recipe suggests that 5 pounds of beef are used to create 20 meals. Thus, the ratio of beef to meals is 5:20. For simplicity, we can reduce this ratio by dividing both sides by 5, resulting in 1:4. This means for every meal, we need a quarter of a pound of beef. The question then asks how many pounds of beef are needed for 80 meals. Since we know a quarter pound of beef is needed for each meal, we can simply multiply the number of meals by 0.25 to get the total pounds of beef required. So, 80 meals x 0.25 pounds = 20 pounds of beef.

Answer:
The number (√5 + 2)(√5 - 2) can be simplified using the difference of squares formula, which states that (a + b)(a - b) = a² - b². In this case:
(√5 + 2)(√5 - 2) = (√5)² - 2² = 5 - 4 = 1
So, the number (√5 + 2)(√5 - 2) is equal to 1, which is a rational number because it can be expressed as a ratio of two integers (1/1). Therefore, the correct answer is:
b. a rational number
Final answer:
The expression ( √5 +2)(√5 - 2) can be simplified using the difference of squares formula. The result is a rationalnumber, making option b. a rational number the correct answer.
Explanation:
The expression ( √5 +2)(√5 - 2) can be simplified using the difference of squares formula. The difference of squares formula states that a^2 - b^2 = (a + b)(a - b). In this case, a = √5 and b = 2. Plugging these values into the formula, we have (√5)^2 - 2^2 = ( √5 +2)(√5 - 2) = 5 - 4 = 1.
Since 1 is a rational number (it can be expressed as a fraction), the correct answer is b. a rational number.
