Max plans to build two side-by-side identical rectangular pens for his pigs that
will enclose a total area of 216 square feet. What is the minimum length of
fencing he will need? What are the dimensions of the total enclosure?
Answer:
864
Step-by-step explanation:
216 + 216 = 432 +216= 448 +216= 864
The minimum length of fencing is 72ft and dimensions are x = 18ft, y=12ft
What is fencing?A fence, wall is a vertical construction used to barricade a space from views, air, or light or to keep out people and animals.
This excludes buildings or parts of buildings that are intended to support a roof, awning, or other horizontal structure, such a building's wall.
let x be the length of each side and y be the width of each side of fence
xy = 216
y = 216/x
total length of fencing = 2x+3y
P = 2x+3y
P = 2x + 3(216/x)
P = 2x + 648/x
On differentiating
P' = 2 - 648/(x²)
for P' = 0
2 = 648/(x²)
(x²) = 324
x = 18
y = 216/18
y = 12ft
Hence length of fencing is = 2x+3y
= 2*18 + 3(216/18)
= 2*18 + 3*12
= 72ft

-12(x-7)= -133
Answer:
The number is 31
Step-by-step explanation:
Let the number be x
Subtract 12 from the number = x - 12
Then multiply the difference by -7 = (-7)*(x - 12)
(-7)(x - 12) = -133
-7x - 12*(-7) = -133
-7x + 84 = - 133
-7x = -133 - 84
-7x = -217
x = -217/-7
x = 31
You have $142.26 in a bank account. The bank requires you to have at least $30 in your account or else you are charged a fee. Write and solve an inequality that represents the amount you can write your next check for without being charged a fee.
Answer:
$142.26 - x ≥ $30
x ≤ $112.26
Step-by-step explanation:
Let the amount you can write on your next check without being charged a fee be x.
Given that you are to have at least $30 in your account or else you are charged a fee then
$142.26 - x ≥ $30
To solve, collect like terms
-x ≥ $30 - $142.26
-x ≥ -$112.26
x ≤ $112.26
Note that on dividing both sides by -1, the sign changes from greater than to less than.

Find an equation for the perpendicular bisector of the line segment whose endpoints
(5,-4) and (-9, -8).
are
Answer:
The equation for the perpendicular bisector of the line segment will be:
[tex]y=-\frac{7}{2}x-13[/tex]
Step-by-step explanation:
Given the endpoints of the line segments
(5,-4)(-9, -8)Determining the slope between (5,-4) and (-9, -8)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-9,\:-8\right)[/tex]
[tex]m=\frac{-8-\left(-4\right)}{-9-5}[/tex]
[tex]m=\frac{2}{7}[/tex]
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 2/7
Thus, the slope of the the new perpendicular line = – 1/m = (-1)/(2/7)= -7/2
Next, determining the mid-point between (5,-4) and (-9, -8)
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-9,\:-8\right)[/tex]
[tex]=\left(\frac{-9+5}{2},\:\frac{-8-4}{2}\right)[/tex]
Refine
[tex]=\left(-2,\:-6\right)[/tex]
We know that the point-slope form of equation of line is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointsubstituting the slope of the perpendicular line -7/2 and the point (-2, -6)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-6\right)=-\frac{7}{2}\left(x-\left(-2\right)\right)[/tex]
[tex]y+6=-\frac{7}{2}\left(x+2\right)[/tex]
Subtract 6 from both sides
[tex]y+6-6=-\frac{7}{2}\left(x+2\right)-6[/tex]
[tex]y=-\frac{7}{2}x-13[/tex]
Therefore, the equation for the perpendicular bisector of the line segment will be:
[tex]y=-\frac{7}{2}x-13[/tex]

The difference of two numbers is 7, and their sum is 49. Find the two numbers.
Answer:
x= 28 and y=21
Step-by-step explanation:
x - y = 7
x + y = 49
add the two equation and the y's will cancel out
2x = 56 divide by 2
x = 28
replace 28 for x in the first equation and solve for y
28 - y = 7
y = 21

simplify –4b + 8c + 12 – 8b – 2c + 6
Answer:
[tex]-12b + 6c + 18[/tex]
Step-by-step explanation:
The key to answering this question is combining like terms. Add or subtract the terms that have the same variable.
1) Let's start with finding all the terms that have a b and combine them - those terms would be -4b and -8b. Add their coefficients (the numbers in front of the variable).
[tex]-4b + 8c + 12 - 8b - 2c + 6 \\= -12b + 8c + 12 - 2c + 6 \\[/tex]
2) Next, let's do the same with all the terms that have a c. In this case, those terms would be 8c and -2c. So, add their coefficients too:
[tex]-12b + 8c + 12 - 2c + 6 \\\\= -12b + 6c + 12 + 6[/tex]
2) Finally, combine the constants (the terms with no variables). Those numbers would be 12 and 6.
[tex]-12b + 6c + 12 + 6\\= -12b + 6c + 18[/tex]
Thus, the answer is [tex]-12b + 6c + 18[/tex].

What is the final elevation if
A butterfly starts at 20 m and changes -16 m?
What is the final elevation if
A diver starts at 5 m and changes -16 m?
?/1
What is the final elevation if
A whale starts at -9 m and changes 11 m?
?/1
What is the final elevation if
A fish starts at -9 meters and changes -11 meters?
Answer: Final elevation of butterfly = 4m
Final elevation for diver = -11m
Final elevation for whale= 2m
Final elevation for fish = -20m
Step-by-step explanation:
Final elevation= Initial poistion + Change.
A butterfly starts at 20 m and changes -16 m.
Final elevation = 20m +(-16m)
= 20-16 m [(-)(+)=(-)]
= 4m
A diver starts at 5 m and changes -16 m.
Final elevation = 5m + (-16) m
= 5m- 16 m [(-)(+)=(-)]
= -11 m
A whale starts at -9 m and changes 11 m.
Final elevation = (-9m)+11m
= 11m- 9m [-a+b=b-a]
= 2m
A fish starts at -9 meters and changes -11 meters
Final elevation = -9+(-11) m
= (-9-11) m [(-)(+)=(-)]
=-(9+11) m [-a-b=-(a+b)]
=-20m
Hence, Final elevation of butterfly = 4m
Final elevation for diver = -11m
Final elevation for whale= 2m
Final elevation for fish = -20m
