What could be a side length of a right triangle a.) 30 in, 45 in, 50 in b.) 30 in, 40 in,50 in c.) 30 in, 40 in, 60 in d.) 25 in, 40 in, 50 in

The pythagorean theorem holds for every right triangle: given the legs and the hypothenuse , the triangle is right if and only if

So, you have to check:

So the first triangle can't be a right triangle.

So the second triangle is a right triangle.

The third triangle can't be right, because it has the same legs but a different hypothenuse

Finally, we have

So the last triangle can't be a right triangle.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
