manuel deposits $10000 for 12 yr in an account paying 4% compounded annually.He then puts this total amount on deposit in anothe

Naddik [55]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$10000\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years\to &12
\end{cases}
\\\\\\
A=10000\left(1+\frac{0.04}{1}\right)^{1\cdot 12}\implies A=1000(1.04)^{12}\\\\\\ A\approx 16010.32$

he then turns around and grabs that money and sticks it for another 9 years,

\end{cases}
\\\\\\
A=16010.32\left(1+\frac{0.05}{2}\right)^{2\cdot 9}\implies A=16010.32(1.025)^{18}
\\\\\\
A\approx 24970.64$

add both amounts, and that's how much is for the whole 21 years.

How will adding the value 75 affect the mean and median of the data set 1, 5, 7, 9 , 9, 10?

kenny6666 [7]

Prior to adding 75, the original data has a mean of 41/6 =6.833 & a median of 8

After adding the 75, the mean becomes 116/7 = 16.571 & the median = 9

So the median increased slightly (from 8 to 9) & the mean increased more quickly (from 6.833 to 16.571)

So it's C :The median increases less than the mean increases.

Bills new porch is rectangular with an area of 50 square feet if the length is two times the width what is two times the width,

svlad2 [7]

Answer:

Step-by-step explanation:

Let L represent the length of the rectangular porch.

Let W represent the width of the rectangular porch.

The area of the rectangular porch is expressed as LW.

Bills new porch is rectangular with an area of 50 square feet. Therefore,

LW = 50 - - - - - - - - 1

if the length is two times the width, it means that

L = 2W

Substituting L = 2W into equation 1, it becomes

2W × W = 50

2W^2 = 50

W^2 = 50/2 = 25

W = √25 = 5

LW = 50

5L = 50

L = 50/5 = 10

The perimeter of he rectangle is

Perimeter = 2(L + W)

Perimeter = 2(10 + 5) = 2 × 15

Perimeter = 30 feet
