C. -46.24
D. 13.6
Please someone
MS.SUE PLEASE HELP
on the first, if it is 5.5 x sqrt5, because sqrt5 is irrational, multiplying it by anything still yields an irrational number
On the cereals, I would read the nutrition labels first. Most likely, none of them are a "best buy". However, I understand the teacher is teaching unit pricing. So divide each cost by the weight to get cost/oz. The "best buy" is the lowest, regardless of what it does to your body.
on the last, any negative number squared is positive.
Thank u so so so much!!!
For the first question, to determine if 5.5 square root of 5 is rational or irrational, we need to know the nature of the square root of 5. To find that out, you can calculate the square root of 5 by using a calculator or any other method you prefer. Once you have the square root of 5, you can multiply it by 5.5 to find the product. If the product is a rational number (can be expressed as a fraction), then Option A is correct. If the product is an irrational number (cannot be expressed as a fraction), then Option B is correct. If the product does not fall into either category, then select Option C. If there is not enough information to determine the nature of the product, select Option D.
For the second question, you need to compare the price per ounce for each cereal to determine which is the best buy. Divide the price of each cereal by its corresponding number of ounces to find the price per ounce. The cereal with the lowest price per ounce represents the best buy. Once you have calculated the price per ounce for each cereal, compare the values and select the cereal with the lowest price per ounce as the best buy.
For the third question, to find the product of (-6.8)^2, square -6.8 by multiplying it with itself. (-6.8)^2 = (-6.8) * (-6.8) = 46.24. Therefore, the correct answer is Option B, 46.24.
