Answer:
0.64
Step-by-step explanation:
Divide the numerator by the denominator. hope this helps! :))
Answer:
A triangles angle always equal to 180 degrees. So if you add up what you already have which is 80+40=120
is not included as a rational number !
<u>Step-by-step explanation:</u>
Here we have , following expressions & we need to identify which of the following is not a rational number . Let's find out:
We know that , Rational Number : A number which can be expressed in form of p/q , where q is not equal to zero !
Here Expressions are:
:
Let's evaluate this expression
⇒ 
⇒ 
Therefore , It is a rational number ! .
:
Let's evaluate this expression
⇒ 
Therefore , It is a rational number ! .
:
Let's evaluate this expression
⇒ 
⇒ 
Therefore , It is a rational number ! .
:
Let's evaluate this expression
⇒
⇒
Therefore , It is not a rational number , as pi is included ! .
Answer:

−4z+11−(12z)
2
+2z−11
Calculate 3 to the power of 2 and get 9.
9z
2
−4z+11−(12z)
2
+2z−11
Expand (12z)
2
.
9z
2
−4z+11−12
2
z
2
+2z−11
Calculate 12 to the power of 2 and get 144.
9z
2
−4z+11−144z
2
+2z−11
Combine 9z
2
and −144z
2
to get −135z

.
−135z
2
−4z+11+2z−11
Combine −4z and 2z to get −2z.
−135z
2
−2z+11−11
Subtract 11 from 11 to get 0.
−135z
2
−2z

$=\sqrt{4^2}\times\sqrt{2^2\cdot3}$
$=4\times2\sqrt3=8\sqrt3$
