Follow the a² + b² = c² formula

The hypotenuse always equal the c
a and b can be the other two numbers and are interchangeable

plug in 5 and 6 into a and b

(5)² + (6)² = c²
simplify
25 + 36 = c²
add
c² = 61
isolate the c, root both sides
c² = 61
√c²= √61
c = √61

Roots are Irrational numbers, and so D) irrational number should be your answer

hope this helps

To find the missing side of the irrational shown below. First, write  the Pythagorean Theorem, then you would substitute the values into the appropriate places. a5 + b6 = ?? .

So the answer would be D.

Luda [366]

Answer:

SAS theorem

Step-by-step explanation:

If \frac{CE}{CB} = \frac{DC}{AC} and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.

\frac{EC}{BC} =  \frac{14}{21} = \frac{2}{3}           \frac{DC}{AC} = \frac{18}{27} = \frac{2}{3}

So,  \frac{CE}{CB} = \frac{DC}{AC}  and m∠ECD = m∠BCA because vertical angles are congruent

Therefore ΔECD is similar to ΔBCA by SAS theorem

A newsletter publisher believes that less than 58% of their readers own a Rolls Royce. For marketing purposes, a potential adver
quester [9]

Answer:

We don´t have at 95% of confidence, evidence to reject the publisher´s claim

Step-by-step explanation:

Population mean      p₀ = 58 %    or    p₀ = 0,58  

Hypothesis Test:

Null Hypothesis                  H₀           p  =  p₀

Alternative Hypothesis      Hₐ           p  <  p₀

For a significance level α = 0,05  means that CI = 95 % or  CI = 0,95

z(c) = - 1,64

MOE = z(c)* √(p*q)/n

p  -  p₀  / √(p*q)/n  = z(s)

And  that  z(s) is in the acceptance region

|z(s)| < |z(c)|

|z(s)| < 1,64

Then if that so we fail to reject H₀ . We don´t have evidence to reject the publisher´s claim

What is the volume in cubic centimeters if the<br> pyramid has a height of 27 centimeters?
aleksley [76]

Answer:

<h2>The volume of the pyramid would be 4500 cm³.</h2>

Step-by-step explanation:

Formulas you would be using:

Volume of a pyramid: V = \frac{bh}{3}  b = base, h = height

Area of a trapezoid: A = \frac{a+b}{2}  h  a = base₁ , b = base₂ , h = height

First, we're going to find the area of the trapezoid, which is the base of the pyramid.

We are given that a = 20, b = 30, h = 20

Plug it in:

\frac{20+30}{2} (20) = 500 cm²

Now that we have found the base of the pyramid, we can plug it in along with the height of the pyramid.

V = \frac{(500)(27)}{3} = 4500 cm³

Hope this helps :D
