Answer:
Option B is correct = 
Step-by-step explanation:
<u>The complete question is:</u> Which of the following options have the same value as 30% of 81?
Group of choices is:
(A) 
(B)
(C) 
(D) 
(E) 
Now, the expression given to us is 30% of 81.
Simplifying the above expression we get;
30% of 81 = 
= 
=
Now, we will solve each of the given options and then see which option matches with our calculation.
Option (A) is given;
=
This doesn't match with our answer, so this option is not correct.
Option (B) is given;
<u><em>This matches with our answer, so this option is correct.</em></u>
Option (C) is given;
This doesn't match with our answer, so this option is not correct.
Option (D) is given;
= 
This doesn't match with our answer, so this option is not correct.
Option (E) is given;
This doesn't match with our answer, so this option is not correct.
Answer:
∠1 + ∠2 + ∠3 = 180°
Step-by-step explanation:
Given : AB II XC
To Show : ∠1 + ∠2 + ∠3 = 180°
Proof: Here, given that AB is parallel to the line XC
⇒ ∠4 = ∠2 (Pair of Alternate angles as AB II XC) ......... (1)
and ∠5 = ∠3 (Pair of Alternate angles as AB II XC) ........... (2)
Now, ∠1 + ∠4 + ∠5 = 180° ( Straight Angle)
But, from above (1) and (2)
∠1 + ∠2 + ∠3 = 180° ( as ∠4 = ∠2, ∠5 = ∠3)
Hence, ∠1 + ∠2 + ∠3 = 180°
Hence Proved.
Answer:
0
Step-by-step explanation:
Note that we start at (0, -4) and end at (7, -4). Thus, the net change in y over the interval [0, 7] is 0, and the average rate of change of f(x) over that interval is thus
0

4cm I think, because it’s usually a even and equal number. But don’t take my word for it.
The height of an airplane as it descends to an airport runway is a quantity which has a unit that is usually rounded to a certain terminating degree of accuracy (i.e. 1, 2, ..., n decimal places)
Thus the set of rational<span> numbers best describes the height of an airplane as it descends to an airport runway.
A rational number is a number which can be represented in the form a/b where a and b are integers. It is usually identified by a terminating or a recurring decimal number.
