Step-by-step explanation:
For example, you use {10}^{2}. That's representing 10 times 10, which equals 100. So basically, all you do is convert {10}^{2} into 10 times 10 and solve, which gives you 100 as the final answer.
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.
Answer: 2/5
Step-by-step explanation: find a number where both the numerator and denominator are divisible by
(2 x 3.95) + (3 x 4.25) + (1 x 5.99) + ((2 x 3.95) + (3 x 4.25) + (1 x 5.99)) x 0.20
= 26.64 - 5.32
= 21.32
Answer:
7.2 units
Step-by-step explanation:
Estimate and Guess
We know that it cannot be 2.9 units long, because it slanted is 6 units long. The closest value to that is 7.2 units.
Answer: 7.2 units
