The population of a town is increasing at a rate of 6.2% per year. The city council believes they will have to add another eleme

kow [346]

Answer:

The correct solution is "4.6".

Step-by-step explanation:

Given:

Interest rate,

r = 6.2%

or,

= 0.062

Amount,

A = 100000

Principle,

P = 76000

As we know,

⇒ $A=P(1+\frac{r}{100} )^n$

On substituting the values, we get

⇒ $100000=76000(1+\frac{6.2}{100} )^n$

⇒ $(1+0.062)^n=\frac{100}{76}$

On taking log both sides, we get

⇒ $n \ log_e(1.062)=log_e(\frac{100}{76} )$

⇒ $n=\frac{ln(\frac{100}{76} )}{ln(1.062)}$

By putting the values of log, we get

⇒ $=4.5622$

or,

⇒ $=4.6$

the length of the flower garden is 3 times as great as the width. what are the dimensions of the flower garden

Nataly_w [17]

Without any more information we can't find the actual numerical representation of the length and width but we can give an expression that will allow us to find them...

We let the width equal x, so the length is 3x. That would be the dimensions...

length = 3x
width = x

So to find perimeter the expression would be

2(3x) + 2(x) =
6x + 2x =
8x

For the area it would be

a= length × width
a = 3x × x
a = 3x^2
