Answer:
13
Step-by-step explanation:
1980 = ( n - 2 ) * 180
n - 2 = 11
n = 13
Answer:
If you assume a six sided die there are 3 odd numbers, 1,3, 5. And 6 total sides, so 3/6 = 1/2 or 50%.
No
Let the groups be x and 2x
Its decimal not natual so can't be divided

Answer:
x = 19
A = 30°
B = C = 75°
Step-by-step explanation:
In an isosceles triangle, the angles opposite the congruent sides have the same measures.
A = B
3x +18 = 7x -58
76 = 4x . . . . . . . . add 58-4x
19 = x . . . . . . . . . divide by 4
Then the equal angles measure ...
A = B = 3(19) +18 = 75
C = 2(19) -8 = 30
Angles A, B, C measure 75°, 75°, 30°, respectively.
_____
<em>Alternate solution</em>
The sum of angles in a triangle is 180°, so you could write ...
(3x +18) +(7x -58) +(2x -8) = 180
12x = 228 . . . . . add 48
x = 19 . . . . . divide by 12
Logarithm functions are the inverses of the exponential function the graph of the given function is attached in the given image.
The points for the given function are (1,0) (3,1) and (9,2)
Given that
Function; 
We have to determine
The graph of the function f(x).
According to the question
The logarithmic function is the inverse of the exponential function.
Function; 
To plot the graph of the given function we have to find the asymptotes;
Vertical asymptote at x =0
The point at x= 1 is,

The point at x= 3 is,

The point at x= 9 is,

Hence, the points for the given function are (1,0) (3,1) and (9,2).
