A16−oz bottle of parmesan cheese costs $5.78, while an 8−oz bottle costs $3.97. which is the better buy? round your answer to the nearest cent if necessary

The 16-oz bottle of parmesan cheese is the better buy.

Step-by-step explanation:

Even though 8-oz is half the amount of 16-oz, that doesn't mean it's cheaper. Let's find the amount of and 8-oz bottle when a 16-oz bottle is $5.78:

16-oz bottle of parmesan cheese = $5.78

A price of an 8-oz bottle when 16-oz is divided by 2:

16 ÷ 5.78 = $2.76

The original price of the 8-oz bottle should've been $2.76 but it's more expensive due to VAT.

So the 8-oz bottle is more expensive, therefore the 16-oz bottle is the better buy!

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
