A mixed number is a number that is a whole number with a fraction
so numbers that are mixed are greater than 1
so therefor since both have to be greater than 1, the fractions have to add up to equal 1
so the mixed numbers are (1 and x) and (1 and y) where x+y=1 so some examples are
1 and 1/2+1 and 1/2
1 and 1/3+1 and 2/3
1 and 1/4 +1 and 3/4
1 and 1/1000+1 and 999/1000
etc
Answer: 127.2
Step-by-step explanation: 1⁄2(a × b) + 3⁄2(b × s) is the formula for triangular pyramids. When you follow this formula for triangular pyramids, you will always get these correct.
The answer is A I am pretty sure. This is because in choice B, you would be dividing 7 and the sum of x + 5. In choice C you would not be multiplying 7 and the sum of x + 5. When he question asks for the product, it is asking for you to multiply. In choice D you would not just be squaring y, you would be squaring 2xy, which is not what we want. We only want to square y, therefore I believe the correct answer is A.
