A rectangular yard measuring 39ft by 63ft is bordered (and surrounded) by a 2 ft fence. Inside, a walk that is wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.
Answers
Given :
A rectangular yard measuring 39 ft by 63 ft is bordered (and surrounded) by a 2 ft fence.
To Find :
The area of this walk.
Solution :
Area of whole park :
[tex]A=39\times 63\ ft^2\\\\A=2457\ ft^2[/tex]
Now, length and breadth after removing the fences is l = 63 - 2( 2) = 59 ft and b = 39 - 2( 2 ) = 35 ft.
Area of inner park :
A' = 35 × 59 ft²
A' = 2065 ft²
Therefore, area of fencing is 2457 - 2065 = 392 ft² .
Hence, this is the required solution.

cupcakes than cookies. If cupcakes sell for $2.50 and cookies for $1.50, which system of inequalities could help Allison determine possible numbers of cupcakes (a) and
cookies (b) that she should buy? (a > 0,b> )
Answers
Answer:a+b ≥40
5+a≤ b
2.50a+1.50b≤ 105
i believe
Step-by-step explanation:
The equations would be:
a+b ≥40 (cupcakes +cookies must be at least 40 total)
5+a≤ b
(At most 5 more cupcakes then cookies)
2.50a+1.50b≤ 105
(The cost of cookies and cupcakes must be less than $105)

John keeps chickens and rabbits in his fenced backyard. He counts a total of 32 heads and a total of 72 legs in his backyard. Write and solve a system of equations in order to find: How many chickens are in John's backyard? Chickens How many rabbits are in John's backyard? Rabbits
Answers
Answer:
System of Equations
c + r = 32 ..... Equation 1
2c + 4r = 72......... Equation 2
We have 28 chickens and 4 rabbits
Step-by-step explanation:
Let the number of chickens be represented by c
The number of rabbits be represented by r
From the question, John counts:a total of 32 heads
32 heads = a total of 32 animals
Hence:
c + r = 32....... Equation 1
c = 32 - r
Also, John counts:
A total of 72 legs in his backyard.
Chickens have: 2 legs
Rabbits have: 4 legs
Hence:
2c + 4r = 72......... Equation 2
System of Equations is:
c + r = 32 ..... Equation 1
2c + 4r = 72......... Equation 2
Lets us substitute 32 - r for c in Equation 2
2(32 - r) + 4r = 72
64 - 2r + 4r = 72
Collect like terms
- 2r + 4r = 72 - 64
2r = 8
r = 8/2
r = 4
This means we have 4 rabbits
Note:
c = 32 - r
r = 4
c = 32 - 4
c = 28
Hence, we have 28 chickens

24tenthousands eqaul?
Answers
Answer:
240000
Step-by-step explanation:
Answer:
240,000
Step-by-step explanation:
Pretend it is only 4 ten thousands. It would be 40,000. Since it is 24, there are 2.4 times more digits, so it would be 240,000 since it is at least 10 times more than a thousand which would be the 40,000 .
In case anyone needs 24 ten thousandths in the future:
0.0024
0.00024 is equal to 24 hundred-thousandths and there are tenths (0.1), hundredths (0.01), and thousandths (0.001). Then ten thousandths would just be a step lower (0.0001) but since there are 24, it would go into the thousandths place but have the four in the ten thousandths. So it would be 0.0024.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
4x = 8 + 3y.....................(1)
x − 2y = −3.......................(2)
Solving Equation (1) and (2), we get
4x = 8 + 3y
4( -3 + 2y) = 8 + 3y
-12 + 8y = 8 +3y
8y - 3y = 8 + 12
5y = 20
y= 4
and, x = -3 + 2y = -3 +2(4) = -3 + 8 = 5
Hence, the temperature of City A is 5° C and temperature of City B is 4° C.

Answer:
x = -7/2
Step-by-step explanation:
½(4x - 8) = 6x + 10
simplify
2x - 4 = 6x + 10
subtract 6x from both sides
-4x - 4 = 10
add 4 to both sides
-4x = 14
divide both sides with -4
x = -14/4
simplify
x = -7/2
Answer:
½(4x - 8) = 6x + 10
4x-8=12x+20
-20-8=12x-4x

Answer:
Mark the lower tick marks with hour numbers; see what hour corresponds to 2/3 mile
Step-by-step explanation:
The upper number line is marked off in 1/3 mile increments.
The tick marks on the lower line divide the unit distance into 6 parts, instead of 3, so each mark on the lower line corresponds to 1/6 mile.
The problem statement tells you the completion rate is 1/6 mile per hour, so we can number the lower tick marks 0, 1, 2, 3, 4, 5, 6 hours, leaving the marks on the upper number line at 1/3 mile, 2/3 mile, and 1 mile.
Then the lower tick mark we have labeled 4 hours will correspond to the upper tick mark labeled 2/3 mile.

Answers
Given :
Wall measures about 65 feet tall and 80 feet wide.
To Find :
If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion.
Solution :
Let, width of sketch is x.
Since, they are in proportion :
[tex]\dfrac{65}{10}=\dfrac{65+8}{x}\\\\x = \dfrac{10\times 73}{65}\\\\x = 11.23\ feet[/tex]
Therefore, width of sketch should be 11.23 feet.
Hence, this is the required solution.

The Big Ben clocktower in London is approximately 316 feet tall. Shana is standing nearby and notices that she casts a 4-foot shadow. If Shana is 5 feet tall, find the length of Big Ben's shadow?
Answers
Answer:
The length of Big Ben shadow is 252.8 feet
Step-by-step explanation:
The given parameters are;
The height of the Big Ben clocktower in London ≈ 316 feet tall
The length of the shadow Shana casts = 4-foot
The height of Shania = 5 feet
Therefore, we have, by similar triangles;
[tex]\dfrac{The \ length \ of \ the \ shadow \ Shana \ casts }{The \ height \ of \ Shania} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{The \ height \ of \ the \ Big \ Ben \ clocktower}[/tex]Substituting the values, gives;
[tex]\dfrac{4 \ feet}{5 \ feet} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{316 \ feet}[/tex]
[tex]The \, length \, of \, the \, shadow \, The \, Big \, Ben \ clocktower \ casts = 316 \ feet \times \dfrac{4 \ feet}{5 \ feet} = 252.8 \ feet[/tex]
The length of the shadow The Big Ben clocktower casts = The length of Big Ben shadow = 252.8 feet
