Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?

1 answer:

6 0

The pythagoream theorem (not sure if I spelled that right...lol): a^2 + b^2 = c^2......where c is the hypotenuse and it is the longest side

5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169....(correct)...so it is a right triangle

What is 575% written as a mixed number?

pav-90 [236]

Answer:

575% as a mixed number is $5\frac{3}{4}$

Explanation:

575% is equivalent to $\frac{575}{100}$ which is equal to 5.75

5.75 = 5 + 0.75

0.75 can be written as $\frac{75}{100}$ . This value can be simplified by dividing both the numerator and the denominator by 25. This would give us $\frac{3}{4}$
