To determine the perimeter of the rectangular flower garden, we need to know the measurement of the sides of the rectangle so we have to know the length and the width. The given measurements are the area, and the relation of the width and the length. From these, we generate equations to calculate the width and the length. We do as follows:

Area = Length x Width

where length = x ft
           width = x - 4 ft
           area = 32 ft^2

32 = x (x -4)
32 = x^2 - 4x

Solving for the positive value of x, 

x = 8 ft = length
width = x -4 = 8 - 4 = 4 ft

Perimeter = 2(length) + 2(width) = 2(8) + 2(4) = 24 ft

A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.
FinnZ [79.3K]

Answer:

A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.

Step-by-step explanation:

An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.

UNO [17]
<h2><u>Question</u><u>:</u><u>-</u></h2>

The shape of Joy’s room is a rectangle 540 cm long by 250 cm wide.

a. Work out the area of his room in Square meters.

b. How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter

<h2><u>Question</u><u> </u><u>No</u><u>.</u><u> </u><u>a</u></h2>

Work out the area of his room in Square meters.

<h3><u>Given</u><u>:</u><u>-</u></h3>

  • Length of the room 540 cm = 540/100 m = 5.4m
  • Breadth of the room 250cm = 250/100 m = 2.5m

<h3><u>To</u><u> </u><u>Find</u><u>:</u><u>-</u></h3>

  • Area of the room.

<h3><u>Solution</u>:-</h3>

We know that:-

Area of a rectangle = (length × breadth)sq.units

Therefore,

Area of the rectangular room = (5.4 × 2.5) square meters

=> Area of the rectangular room = 13.5 square meters.

<h3><u>Answer</u><u>:</u><u>-</u></h3>

Area of his room is 13.5 square meters.

<h2><u>Question</u><u> </u><u>No</u><u>.</u><u> </u><u>b</u></h2>

How much does he pay to buy flooring for his room where flooring costs $ 40 per square meter

<h3><u>Given</u><u>:</u><u>-</u></h3>

  • Cost in per square meter = $40
  • Area of the room = 13.5 square meters (From question a)

<h3><u>To</u><u> </u><u>Find</u><u>:</u><u>-</u></h3>

  • Total cost of flooring

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Flooring cost in 1 squre meter = $40

Flooring cost in 13.5 square meters = $(40 × 13.5) = $540

<h3><u>Answer</u><u>:</u><u>-</u></h3>

He pays $540 to buy flooring for his room.

Sara invests $1,200 each year in an IRA ( 12 years in an account that earned 5%
Sati [7]
A)

\bf \qquad \qquad \textit{Future Value of an ordinary annuity}&#10;\\\\&#10;A=pymnt\left[ \cfrac{\left( 1+\frac{r}{n} \right)^{nt}-1}{\frac{r}{n}} \right]&#10;\\\\

\bf \begin{cases}&#10;A=&#10;\begin{array}{llll}&#10;\textit{original amount}\\&#10;\textit{already compounded}&#10;\end{array}&#10;\begin{array}{llll}&#10;&#10;\end{array}\\&#10;pymnt=\textit{periodic deposits}\to &1200\\&#10;r=rate\to 5\%\to \frac{5}{100}\to &0.05\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}\\&#10;\textit{each year, once}&#10;\end{array}\to &1\\&#10;&#10;t=years\to &12&#10;\end{cases}

B)

let's say after 12years, she ended up with a value of say "P"
so.. now she's just sitting on P, making no more deposits to it
just taking whatever the compound 5% interest will give, thus

\bf \qquad \textit{Compound Interest Earned Amount}&#10;\\\\&#10;A=P\left(1+\frac{r}{n}\right)^{nt}&#10;\qquad &#10;\begin{cases}&#10;A=\textit{compounded amount}\\&#10;P=\textit{original amount deposited}\to &\boxed{P}\\&#10;r=rate\to 5\%\to \frac{5}{100}\to &0.05\\&#10;n=&#10;\begin{array}{llll}&#10;\textit{times it compounds per year}\\&#10;\textit{again, is only once}&#10;\end{array}\to &1\\&#10;&#10;t=years\to &11&#10;\end{cases}


C)

from A) she made 1,200 every year, for 12 years that's 1200*12, that's how much she put out of pocket, if you got an amount P from A), then the interest is just the difference, or P - (1200*12)

from B), she started with an original amount of P, and ended up with a compounded amount of A after 11years, so the interest is just also the difference, or A - P

add those two folks together, and that's the total interest she got for the 23  years
