After 14 months after the first month would the sales reach $9000
For given question,
A Hammer Hardware has sales of $5000 in its first month.
The sales were to increase by 4% every month.
We need to find the number of months after the first month would the sales reach $9000
Let the exponential function for sales is,
f(n)= a (1 + r)^{n}
where, n is the number of months
a is the sales of the first month
r is the rate of increment
So, a = $5000, r = 0.04, f(n) = $9000
Substitute values in above equation.
⇒ 9000 = 5000 × (1 + 0.04)^{n}
Solve above equation for n.
⇒ 1.8 = (1.04)^n
⇒ n =
⇒ n = 14.9
⇒ n ≈ 15
Therefore, after 14 months after the first month would the sales reach $9000

Answer:
Step-by-step explanation:
the bar above 36 means that the digits 36 are being repeated
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.13636.. ( multiply both sides by 10 and 1000 )
10x = 1.3636... (1)
1000x = 136.3636... (2)
subtract (1) from (2) thus eliminating the repeating digits
990x = 135 ( divide both sides by 990 )
x = =

Answer:
There are 8 boys in the chorus and 16 girls in the chorus
The graph in the attached figure
Step-by-step explanation:
Let
x----> the number of boys
y----> the number of girls
we know that
-----> equation A
----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (8,16)
see the attached figure
therefore
There are 8 boys in the chorus
There are 16 girls in the chorus
