Explecit formula
hmm, seems to be a geometric sequence
so
an=a1+d(n-1)
d=common differnce
a1=first term
given
a1=firstterm=9.2
and the difference between each tierm is 1.8
an=9.1-1.8(n-1) is da equation
so 4th option
Hello!
First you have to find the area of the space
300 * 500 = 150000
Next you have to find the space 5 people take up
5 * 5 = 25
Divide these two numbers
150000 / 25 = 6000
multiply this by the amount of people take up that space
6000 * 5 = 30000
The answer is D)30,000 people
Hope this helps!
A convex figure with three sides is triangle. The sum of the measures of all interior angles of the triangle is 180°.
Let
be interior angles of this triangle. Then

Find exterior angles of this triangle:
1.
is exterior angle adjacent to the interior angle 
2.
is exterior angle adjacent to the interior angle 
3.
is exterior angle adjacent to the interior angle 
The sum of the measures of all exterior angles is

Answer: 360°
12x3=36 That is the equation
