9514 1404 393

Answer:

  250 days

Step-by-step explanation:

If the number of drops increases by a factor of 20/8, the expected life will decrease by the inverse of that factor: 8/20.

The expected life is (8/20)(625 days) = 250 days.

Yolanda filled 2liters bottles with water for a day at the park with her family. Her family drank 11.73 liters .How many liters
kotykmax [81]

Answer:

1.99 L

Step-by-step explanation:

In the question it is mentioned that

The total liters of the water filled is 2 liters

But the family drank 11.73 liters

How should it be possible that the family drank is more than the total liters

So here we assume that the family drunk water should be in milliliters

Now the number of liters left is

= 2,000 ML - 11.73 ML

= 1988.27 ML

Now convert into liters which is

= 1988.27 ÷ 1,000

= 1.99 L

A newborn child receives a $6,000 gift toward a college education from her grandparents. How much will the $6,000 be worth in 19
shusha [124]

Solution:

To find the amount after 19 years, we use the compound interest formula.

\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \text{where;} \\ A\text{ is the amount after t-years} \\ P\text{ is the principal or initial deposit} \\ r\text{ is the rate} \\ n\text{ is the number of compounding} \\ t\text{ is the time } \end{gathered}

Given:

\begin{gathered} P=\text{ \$6000} \\ t=19\text{years} \\ r=7.8\text{ \% =}\frac{7.8}{100}=0.078 \\ n=4\text{ (compounded quarterly)} \end{gathered}

Substituting these values into the formula;

\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ A=6000(1+\frac{0.078}{4})^{4\times19} \\ A=6000(1+0.0195)^{76} \\ A=6000(1.0195)^{76} \\ A=6000\times1.0195^{76} \\ A=26,036.39 \end{gathered}

Therefore, the amount $6,000 will be worth in 19 years if it is invested at 7.8% compounded quarterly is $26,036.39
