If the lengths of the legs of a right triangle are 5 and 12, what is the length of the hypotenuse?
kondor19780726 [428]

Answer:

13

Step-by-step explanation:

If we have a right triangle, we can use the Pythagorean theorem to find the hypotenuse

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144= c^2

169 = c^2

Take the square root of each side

sqrt(169) = sqrt(c^2)

13= c

A local school has 14 kindergarten teachers. Of these teachers, 4 are Hispanic, 5 are bilingual, and 3 are both Hispanic and bil
navik [9.2K]

Answer:

P(Hispanic or Bilingual) = 0.429.

Step-by-step explanation:

This question is solved treating these events as Venn probabilities.

I am going to say that:

Event A: Hispanic

Event B: Bilingual

Out of 14 teachers, 4 are Hispanic, 5 are billingual, and 3 are both:

This means that:

P(A) = \frac{4}{14}, P(B) = \frac{5}{14}, P(A \cap B) = \frac{3}{14}

What is the probability that teacher is Hispanic or bilingual?

This is:

P(A \cup B) = P(A) + P(B) - P(A \cap B)

With the values that the exercise gives us:

P(A \cup B) = \frac{4}{14} + \frac{5}{14} - \frac{3}{14} = \frac{4 + 5 - 3}{14} = \frac{6}{14} = 0.429

So

P(Hispanic or Bilingual) = 0.429.

Answer:

  (d)  A = 18 units²

Step-by-step explanation:

Line CE can be considered to be the base of two triangles. It is 6 units long. The upper triangle is 4 units high, and the lower triangle is 2 units high. The formula for the area of a triangle is ...

  A = 1/2bh

Then the sum of the areas of the two triangles is ...

  A = 1/2(6)(4) +1/2(6)(2) = 12 +6 = 18

The area of the polygon is 18 square units.
