The synodic month, or complete cycle of phases of the Moon as seen from Earth, averages 29.530588 mean solar days in length (i.e., 29 days 12 hours 44 minutes 3 seconds); because of perturbations in the Moon’s orbit, the lengths of all astronomical months vary slightly. The sidereal month is the time needed for the Moon to return to the same place against the background of the stars, 27.321661 days (i.e., 27 days 7 hours 43 minutes 12 seconds)
Answer:
(a)100,000
(b)53,000
Step-by-step explanation:
(a)
Let the total votes be x.
Given 31% of x=31000
So,total votes are =100,000
_________________________________
(b)
Winning margin =53000−31000=22000.
=
Therefore, the Winning margin is 22000.

Let the numbers be:
a, a+b, a+2b
mean of the numbers is:
(a+a+b+a+2b)/3=10
(3a+3b)/3=10
a+b=10
thus second term is 10
The sum of square will be:
((10 - b)² + 10² + (10 + b)²<span>) / 3 = 394
</span>(100 - 20b + b² + 100 + 100 + 20b + b²<span>) / 3 = 394
</span><span>(300 + 2b</span>²<span>) / 3 = 394
</span>(150+b²)=591
b²=441
b=-21,21
thus the numbers will be:
10-21, 10, 10+21
=-11,10,31
Answer:
True
Step-by-step explanation:
subtract 
from both sides

Answer:
SETS ≥ 44.5
Step-by-step explanation:
748-214=534, Leah still needs at least 534 knives.
Let X be the numbers of sets of knives, 12X ≥ 534, X ≥ 44.5.
The minimum of X is 45 since there's no shop sells "0.5" sets of knives.
