Answer:

9.9 years

Step-by-step explanation:

A = P e ^(rt)

Where A is the amount in the account

P is the amount invested

R is the interest rate

t is the time

P = 8500

r =7% = .07

A = 17000

Substituting into the equation

17000=8500 e^(.07t)

Divide each side by 8500

17000/8500=8500/8500 e^(.07t)

2 = e^(.07t)

Take the natural log of each side

ln (2) = ln e^(.07t)

ln(2) = .07t

Divide each side by .07

ln(2)/.07 = .07t/.07

ln(2)/.07 = t

9.902102579=t

Rounding to one decimal place

Airida [17]

Answer:

672 ways

Step-by-step explanation:

The total number of ways the friends were supposed to sit without restrictions would have been = 6!

= 720 possible ways.

If the girs should sit on the first or last sit

The possible arrangement= 2!4!

= 2*24

= 48

But now the two girls should be arranged in such a way that the don't sit on either the first or the last chair.

So the possible way now is= way without restriction - way if the girls are to sit at either first or last sit

= 720-48

= 672

kirza4 [7]

Answer:

D get $ 63, G get $9, J get $18.

Step-by-step explanation:

Given : D has 90 dollars. He gives 0.1 of them to G. He gives 0.2 of them to J. He keeps the rest.

To find : How much does each person get?

Solution :

D has 90 dollars.

He gives 0.1 of them to G.

i.e. 0.1\times 90=9

So, he gives $9 to G

He gives 0.2 of them to J.

i.e. 0.2\times 90=18

So, he gives $18 to J

Total he give 9+18=$27

D will left with \$90-\$27=\$63

Therefore, D get $ 63, G get $9, J get $18.
