The dimension that maximize the are of the pen is 45 ft by 90 ft.
Area of a rectanglearea = lw
where
l = length
w= width
Therefore,
perimeter of a rectangle = 2(l + w)
The barn is occupying one part of the rectangle . Therefore,
perimeter = 2l + w
180 = 2l + w
w = 180 - 2l
area = lw
Therefore,
area = l(180 - 2l)
area = 180l - 2l²
To maximize area
l = -b / 2a
l = - (180) / 2 × -2
l = -180 / -4
l = 45 ft
Therefore,
w = 180 - 2(45)
w = 180 - 90
w = 90 ft

Answer:
Patrick's statement is incorrect
Step-by-step explanation:
Crackers come in packages of 24
cheese slices come in packages of 18
He wants one cheese slice for each cracker
Patrick made the statement below "if Andy doesn't want any crackers or cheese slices left over he needs to buy at least 432 of each"
Patrick's statement is incorrect
The lowest common multiple ( L. C. M) of 24 and 18 is 72
Therefore, Andy needs 72 packages of crackers and 72 packages of cheese slice so that no crackers or cheese slice will remain.

What is the value of z?
Answer: 58 degrees
Step-by-step explanation:
We can see that this triangle is an isosceles triangle so that means the two bottoms angles will be equal
Point S must be equal to point U
z = 58 degrees
Check if this is true:
Angle sum of a triangle: 180 degrees
58 + 58 = 116
180 - 116 = 64
Point T is 64
58 + 58 + 64 = 180

Kamala was ordering tickets from a local theater for two different events. The first event cost $24.95 per ticket plus a $5 processing fee. The second event cost $35.75 per ticket plus a $9.95 processing fee. If Kamala purchased the same number of tickets to each event, what is the simplified expression for the total cost for both events?
Answer:
T=60.7x+5+14.95Step-by-step explanation:
let the number of tickets be x
and the number is the same for both tickets
for the first event
the cost is =24.95x+ 5
for the second event
the cost is =35.75x+ 9.95
for both events the total cost is
T=24.95x+ 5+35.75x+ 9.95
T=24.95x+35.75x+5+ 9.95
The simplified expression for the total cost for both events T=60.7x+5+14.95help me please and thank you

An object is launched at 18.4 meters per second (m/s) from a 36.8-meter tall
platform. The equation for the object's height s at time t seconds after launch is
s(t) = -4.9t2 + 18.4t + 36.8, where s is in meters.
Answer:
Step-by-step explanation:
Given the equation for the object's height s at time t seconds after launch is
s(t) = -4.9t^2 + 18.4t + 36.8
Since are not asked what to look for, we can as well lok for the time taken for the ball to hot the ground. The ball hits the ground at when s(t) = 0. The equaton becomes:
0 = -4.9t^2 + 18.4t + 36.8
Multiply through by -10
49t^2 - 184t - 368 = 0
factorize the resulting expression
t = 18±√184²-4(49)(-386)/2(49)
t = 18±√338564+75656/78
t = 18±√414220/78
t = 18±643.599/78
t = 661.559/78
t = 8.48secs
Hence the object reaches that ground after 8.48seconds

2 friends went to see a movie. 1 friend ordered a movie ticket for $5.50 and a popcorn for $3.75. The other friend ordered a movie ticket and a drink for $3. If they wanted to split the cost evenly, around how much did each friend pay? which anseris it a piece
$6.13 a piece
$8.88 a piece
$7.95 a piece
$10.05 a pie
Answer:
$8.88
Step-by-step explanation:
5.50+5.50+3.75+3.00=17.75÷2=8.88
Answer:
Its A.
Step-by-step explanation:
Add the price up to find the total: 5.50 + 3.75 + 3 = $12.25. Since there were 2 people and they wanted to split the cost- they pay half half. So 12.25 divided by 2 is $6.12.5 but you gotta round it to get an answer hats there so you round it up to 6.13.

Answer:
B both are proportional
Step-by-step explanation:
so i think by proportional its linear?
so the graph is linear because its a line and its a function, but for the table we first have to find the slope by using the equation
y2 - y1 / x2 - x1
(4, 1.31) and (8, 2.62) will be the points we will use
2.62 - 1.31 / 8 - 4
1.31/4
0.3275x
now i think we use a point we did not use yet sooo (16, 5.24)
we substitute
y = 0.3275x + b
5.24 = 0.3275(16) + b
5.24 = 5.24 + b
b = 0
so the equation would be
y = 0.3275x
now we check with the last point given
6.55 = 0.3275(20) ?
6.55 = 6.55
so i think the answer is both are proportional ?

Write a proof for the biconditional using the conditional and converse.
A triangle is equilateral if and only if all the side lengths of the triangle are equal.
Answer: see below
Step-by-step explanation:
Hypothesis (p): A triangle is equilateral
Conclusion (q): The side lengths are equal
Conditional (p → q): If a triangle is equilateral, then its side lengths are equal.
The conditional statement is TRUE
Converse (q → p): If the side lengths of a triangle are equal, then it is equilateral.
The converse statement is TRUE
Since p → q and q → p are both TRUE, then it is biconditional.
P(sports U Work)= _%. The following two way table describes students after school activities. Find the probability that a randomly selected student either does sports or works
Answer: 75%
Step-by-step explanation:
20+20+25+3+2+5=75
Total of 100 students
75/100=0.75
=75%
The percentage of P(sports ∪ work) is equal to 75%.
We have given the table
we have to find the percentage of sports and work
What is the formula for the total?
Total=Work+sports
Therefore we have to add the values of work and sports
20+20+25+3+2+5=75
Total of 100 students
75/100=0.75
=75%
Therefore the percentage of P(sports ∪ work) is given by 75%.

Find the inverse. Check your answer algebraically and graphically.
f(x) = 4x/x − 9, x ≠ 9
f^-1(x)=
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
[tex]\stackrel{f(x)}{y}~~ = ~~\cfrac{4x}{x-9}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{4y}{y-9}}\implies xy-9x=4y\implies -9x=4y-xy \\\\\\ -9x=y(4-x)\implies \cfrac{-9x}{4-x}=y\implies \cfrac{9x}{x-4}=\stackrel{f^{-1}(x)}{y}[/tex]
how to test algebraically? well, for any (a,b) pair in f(x), its inverse will have another pair but (b,a), hmmm let's plug hmmm say
f(10) = 40, and f⁻¹(40) = 10.
we could plug more values in each, same pair will come up.
as far as testing them graphically, Check the picture below.

Answer:
B. SSA
Step-by-step explanation:
Since segments JK and RQ are parallel, they are similar by both extending at the same angle and both segments formed by the parallel lines being proportional segments.Since the lengths of segments KZ and ZR are given, they are similar because they are proportional.Since vertical angles are always equivalent by the Vertical Angles Theorem, angles JZK and RZQ are congruentBecause we have 2 sides with a non-included (not in-between the two sides) angle, the triangles are similar by SSA Similarity.

A fire hydrant is 30 in. tall and casts a shadow 8 in. long. how tall is a
nearby tree that casts a shadow 4 ft long?
Using proportions, it is found that a tree that casts a shadow 4 ft long is 180 in. tall.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, a fire hydrant that is 30 in. tall and casts a shadow 8 in. long. We want to find the height of a tree that casts a shadow of 4 ft = 4 x 12 = 48 inches. Hence, the rule of three is given by:
30 in - 8 in
h in - 48 in
Applying cross multiplication:
h = 48 x 30/8
h = 6 x 30.
h = 180 in.
