Remember:
(a/b)÷(c/d)= $\frac{ \frac{a}{b} }{ \frac{c}{d} }=( \frac{a}{b} )( \frac{d}{c} ) = \frac{ad}{bc}$
so
(7/10)÷(1/5)= $\frac{ \frac{7}{10} }{ \frac{1}{5} }=( \frac{7}{10} )( \frac{5}{1} ) = \frac{(7)(5)}{(10)(1)}= \frac{35{10}= \frac{7}{2}$

the answer is 7/2

Well, if you take x to be 25 seconds, there are 2.4x in 1min. So, that multiplied by 60, would be 144x. Therefore, 1/4 multiplied by 144x should be the answer.

Answer:

Using continuous interest 6.83 years before she has $1600.

Using continuous compounding, 6.71 years.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

Continuous compounding:

The amount of money earned after t years in continuous interest is given by:

$P(t) = P(0)e^{rt}$
