All you do is move the decimal
Let
A = population of town A,
B = population of town B,
C = population of town C.
Because the population of town B is 50% greater than that of town A,
B = 1.5A (1)
Because the population of town C is 20% greater than that of town A,
C = 1.2A (2)
From (1), obtain
A = B/1.5 = (2/3)B (3)
Substitute (3) into (2).
C = 1.2*(2/3)*B = 0.8B
Divide each side by 0.8.
1.25C = B
This result means that B is 25% greater than C.
Answer: 25%
Answer:
x = 15
Step-by-step explanation:
137+28=165
All angles in a triangle add up to 180
So 180-165 = 15
15 = x
Answer:
A formula for the nth term of the given sequence is:
Step-by-step explanation:
Given the sequence
36, -48, 64...
We know that a geometric sequence has a constant ratio r and is defined by
Compute the ratios of all the adjacent terms
The ratio of all the adjacent terms is the same and equal to
Therefore, the given sequence is a geometric sequence.
As the first element of the sequence is
so substituting and in the nth term
Therefore, a formula for the nth term of the given sequence is:
