I have 183 feet of fencing. The length of the court is 32 feet more than the width. One of the shorter sides will be 5 feet shor
Aliun [14]
Okay so the total is 183. So we can say 183 = 
Let's call the width (the longer side) x.
We know that we have x, x + 32, and x - 5.
We can say 183 = x + (x + 32) + (x - 5).
Let's solve for x.
x = 52. 
So we know the length is 84 feet, the shorter side has 47 feet, and the longer side has 52 feet.

The length of a rectangle is 3 m less than twice the width if the area of the rectangle is 66 5 m² find the dimensions
goblinko [34]

Let the width be x.

Then,Length = ( 2x - 3 ) m

<u>According to the question, </u>

Area of rectangle = 665 m² [ Given ]

Formula: Area of rectangle = Length × Width

\sf \implies \: length \:  \times breadth = 665 \: m {}^{2}

\sf\implies \: (2x - 3) \times x = 665

\sf \implies \: 2 {x}^{2}  - 3x = 665

\sf \implies \:  {2x}^{2}  - 3x - 665 = 0

<u>By split middle term </u>

\sf \implies \: 2 {x}^{2}  - 38x  + 35x - 665 = 0

\sf\implies \: 2x(x - 19) + 35(x - 19) = 0

\sf \implies \: (2x + 35) = 0 \: or \: (x  - 19) = 0

\sf \implies \: x =  \dfrac{ - 35}{2}  \: or \:  \: x = 19 \:

Note: Ignore negative number.

Now,

Width of a rectangle = 19 m

Length of a rectangle = 2x - 3 = 2 × 19 - 3 = 38 - 3 = 35 m

Your friend brings hot chocolate to school in the cylindrical thermos and drinks from her cylindrical mug shown.
Vesna [10]
Volume=height times area of base
base=circle so area of base=pir^2
ok so solume=height times pi times r^2


1.
thermos, h=10, r=2
therefor
 volume=10pi2^2=
 volume=10pi4=
40pi in^3 is brought to school


2. inside is 4 inches deep
h=4, r=1.5
volume=4pi1.5^2
volume=4pi2.25
volume=9pi
answer is 9pi in^3


3. so find 80% of 9pi
80%=0.8
0.8 times 9pi=7.2pi in^3
each times is 7.2pi in^3


4. ok so this is assuming that you fill the mug to 80% (7.2pi) each time and the remainder is it less or more or equal to half of 7.2pi so

total in thermos=40pi
each pour=7.2pi
40pi-7.2pi-7.2pi-7.2pi-7.2pi-7.2pi=4pi
is 4pi more or less than 7.2pi
7.2pi/2=3.6pi
4pi>3.6pi
it is MORE


1. 40pi in^3
2. 9pi in^3
3. 7.2pi in^3
4. MORE than half

A koala weighs 20 pounds. In her pouch she carries her joy that weighs 20 ounces. What is the combined weigth of the adult koala
sdas [7]

Answer: The answer is 21.25 pounds.


Step-by-step explanation:  Given that the weight of Akoala is 20 pounds. Also, she is carrying her joey with her having weight 20 ounces. We need to find the combined weight of the adult Akoala and her joey in ounces.

For that, first we need to conver ounces to pounds.

We know

1~\textup{pound}=16~\textup{ounces}\\\\\Rightarrow 1~\textup{ounce}=\dfrac{1}{16}~\textup{pounds}\\\\\Rightarrow 20~\textup{ounces}=\dfrac{1}{16}\times 20=\dfrac{5}{4}=1.25~\textup{pounds.}

Therefore, the combined weight is given by

W=20+1.25=21.25~\textup{pounds.}

Thus, the answer is 21.25 pounds.
