Answer:
11/18
Step-by-step explanation:
1/9 + 1/3 + 1/6
Adjust fractions based on the LCM,
2/18 + 6/18 + 3/18
Apply the fraction rule,
(2 + 6 + 3)/18
Answer,
11/18
A is the correct answer

Answer:
Part I : 2160°
Part II : 165°
Part III : 36 sides.
Part IV : 10 sides.
Step-by-step explanation:
Part I : If the polygon has 14 sides, then the sum of all the interior angles of a polygon will be = (14 - 2) × 180° = 2160°. (Answer)
Part II : If the polygon has 24 sides, then the sum of all the interior angles of a polygon will be = (24 - 2) × 180° = 3960°.
Therefore, the measurement of each interior angles will be = . (Answer)
Part III : Given that 10° is each exterior angle of a polygon. So, each interior angle is (180 - 10) = 170°.
If the number of sides is n, then,
⇒ 10n = 360
⇒ n = 36 sides. (Answer)
Part IV : Sum of the all interior angles is 1440°.
If it has n sides, then (n - 2) \times 180 = 1440
⇒ n - 2 = 8
⇒ n = 10 (Answer)
You can use AA since the parallel lines make corresponding angles congruent.
Answer:
2000
Step-by-step explanation:
One way to do this is to add half of a thousand, then zero all digits to the right of the thousands place.
2371 +500 = 2871
With digits zeroed, this is ...
2000
__
<em>Additional comment</em>
The traditional instruction is to look at the digit in the place to the right of the thousands place. (It is 3.) If it is 5 or more, you increase the number by 1 in the place you're rounding to. (No increase is needed.) Then you set all digits to the right of the thousands place to zero.
