Answer:
B. For any two real numbers, the first is non-negative, the second is negative, and the difference is positive.
Step-by-step explanation:
To answer this question, I'll analyse the mathematical statements one at a time
The analysis is as follows:
∀x -> This means real number x
∀y -> This means real number y
(x ≥ 0) -> Such that real number x is greater than or equal to 0. In other words, x is positive
∧ -> and
(y < 0)-> y is less than 0. In other words, y is negative
So, there are two real numbers: x and y
→ (x – y > 0) -> Their difference is greater than 0. In other words, their difference is positive
When the analysis above is compared to the list of given options; the option that match is B.
Hence, option B answers the question.
Peter waled 8900 feet. How many miles is it?
Well, it's surely at least one mile! 8900 is bigger than 5280. And how much more than one mile? let's subtract 5280 from 8900:
8900-5280=3620.
now, this is less than another mile: so it's more than 1 but less than 2 miles: only options 3) and 4) are possible.
so the exact answer is 1.685 and an approximation is 1.7 (because from digit 5 up we round up: 1.64 would be rounded down to 1.6)- the correct answer is 4)!!!
how much is 3600 feet?

1 <span>an isosceles triangle because two equal sides</span>
Answer:
The last three,
2 cm, 5 cm, 6 cm
4 cm, 8 cm, 11 cm
10 in, 5 in, 13 in
As long as any two sides added together are long than the third side, it works as a triangle!
