The perimeter (P) of a polygon is all the values of all the sides added together. (Length+Length+Width+Width) If the length (L) of the rectangle is 2 feet longer than twice the width (W), then L=2W+2. So now the perimeter is 2W+2+2W+2+W+W = P. This simplifies to 6W+4=P. If we know the perimeter is 244, then 6W+4=244. Then subtract four and divide by 6. W=40. If L=2W+2, then L=2(40)+2, or L=82. SO.....
The width is 40 feet
The length is 82 feet

Lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. Ari buys 3 pounds of apples and 2 pounds of bananas
Anarel [89]
5x + 3y= 8.50
3x + 2y= 5.25

Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation

Amy makes an initial investment of $5000. The investment loses 13.5% each year. Find the amount Amy has at the end of 8 years.
Pani-rosa [81]

Answer:

\$1,567.11

Step-by-step explanation:

we know that

The equation of a exponential decay function is given by

y=a(1-r)^x

where

y is the value of the investment

x is the number of years

a is the initial value

r is the rate of change

we have

a=\$5,000\\r=13.5\%=13.5/100=0.135

substitute

y=5,000(1-0.135)^x

y=5,000(0.865)^x

Find the amount Amy has at the end of 8 years

For x=8 years

substitute the value of x

y=5,000(0.865)^8=\$1,567.11

| 15. Aliyah runs approximately 5.4 miles per hour.
miss Akunina [59]

Answer: 33.33 minutes longer.

Step-by-step explanation :

We need to remember the following formula:

 t=\frac{d}{V}

Where "t" is the time, "d" is the distance and "V" is the speed.

We know that she runs approximately 5.4 miles per hour, then:

V=5.4\ \frac{mi}{h}

Since she plans to run 9 miles on Tuesday, her run's time on Tuesday will be:

t_1=\frac{9\ mi}{5.4\ \frac{mi}{h}}\\\\t_1=\frac{5}{3}\ h

Making the conversion from hours to minutes, we get:

(\frac{5}{3}\ h)(\frac{60\ min}{1\ h})=100\ min

Since she plans to run 12 miles on Thursday, her run's time on that day will be:

t_2=\frac{12\ mi}{5.4\ \frac{mi}{h}}\\\\t_2=\frac{20}{9}\ h

Making the conversion from hours to minutes, we get:

(\frac{20}{9}\ h)(\frac{60\ min}{1\ h})=133.33\ min

Finally in order to find how many longer will her run be on Thursday compared to Tuesday, we need to make the following subtraction:

t_2-t_1=133.33\ min-100\ min=33.33\ min
