Answer:

2. (only)

Step-by-step explanation:

The Pythagorean theorem tells you the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. To determine if these are right triangles, determine if that condition is met.

1. 3^2 +5^2 = 9 + 25 = 34 ≠ (√35)^2 . . . . not a right triangle

2. 5^2 +4^2 = 25 +16 = 41 = (√41)^2 . . . a right triangle

3. 6^2 +8^2 = 36 +64 = 100 ≠ (√10)^2 . . . . not a right triangle

4. 3^2 +3^2 = 9 +9 = 18 ≠ (3√3)^2 = 27 . . . . not a right triangle

Answer:

$\boxed{7-4=11\:or\:6+3=9}$

Step-by-step explanation:

Let $p$ and $q$ be two <em>propositional statements</em>.

The disjunction $p\vee q$ is true if either $p$ or $q$ is true or both are true.

In the given options;

The statement;

$7-4=11$ is false

But;

$6+3=9$ is true.

Hence,

$7-4=11\:\vee \:6+3=9$ is true

Your boss gave you a raise. Your weekly salary went from $375 to $450. What was your percent raise?

Yuri [45]

<span>1. Find the difference
2. Divide the difference by the original number it went up from.
</span>
450-375 = 75

75/375 = 0.2

You got a 20% raise.

Proof:
375*.2 = 75
375+75 = 450
