DaniilM [7]

Answer: 19 years

Step-by-step explanation:

Given

Amount invested $\$400$

Rate of interest $R=6\%$

after 1-year amount becomes

$A=400\left (1+6\%\right)\\A=400\left (1+0.06\right)\\A=400\times 1.06\\A=\$424$

After n years it is

$A=400\left (1.06\right)^n$

Sum accumulated is $\$1200$

$\Rightarrow 1200=400\left(1.06\right)^n\\\Rightarrow 3=\left(1.06\right)^n\\\text{Taking log both sides}\\\Rightarrow n=\dfrac{\ln 3}{\ln 1.06}\\\\\Rightarrow n=18.85\approx 19\ \text{years}$

grandymaker [24]

Solution: We are given that the population of Virginia is 8 million.

Let x be the population of Nevada.

We are given population of Virginia is 2.8 million less than 4 times the population of Nevada.

$\therefore 4x-2.8=8$

$4x=8+2.8$

$4x=10.8$

$x=\frac{10.8}{4} =2.7$

The first step is to on both sides.

add 2.8

The second step is to on both sides.

divide 4

The population of Nevada is million.
