When x varies inversely with y then you'll have
xα1/y
x=k/y where k is the proportionality constant
when x=8. y=10. k=?
8=k/10
make k the subject of the formula
k=10×8
k=80.

When x=6. y=?.k=80
6=80/y
Make y the subject of the formula
y=80/6
y=40/3

PLEASE EXPLAIN!!!
andrew11 [14]
<span>The easiest thing to do is convert all the measurements to yards...
 18ft = 6 yards
 6 inch = 1/6 yard     ( 6 inches = 1/2 ft.... so 1/6 yard)
  so the volume is V = 6 x 6 x 1/6
 Then all you do is calculate the cost. I hope this helps you out</span>

Answer:

About 31 years

Step-by-step explanation:

Given data

Principal= $3500

Rate=  4.75%

Final amount= $15,000

Time=??

The expression for time on compound interest is

Calculate time, solve for t

t = ln(A/P) / r

substitute

Calculate time, solve for t

t = ln(15000/3500) / 0.0475

t= ln(4.2857)/ 0.0475

t= 1.4552/0.0475

t= 30.63 years

Hence it will take about 31 years
