Answer:
p = 2 * w + 54
Step-by-step explanation:
To know the number of feet Alice needs, you must calculate the perimeter, the perimeter of a rectangle would be the sum of its sides, that is, twice the width and twice the length.
This time they give us the length that is equal to 27 feet, therefore, the equation of the perimeter would be:
p = 2 * w + 2 * l
p = 2 * w + 2 * 27
p = 2 * w + 54
Therefore, to know exactly what Alice needs, you need to know the value of the width and shortest side.
in how many ways can the classes math, language arts, science and social studies be ordered on student schedules as the first four classes of their day
Answer:
16
Step-by-step explanation:
theres 4 different subjects that could be in each of 4 different slots, eg, science, ss, ela, or math could be in slot one, or the same for slot two, and so on and so forth.4 x 4 = 16
The required number of ways to study 4 different subject to first four classes is 16
What is method of counting?If we have m number of works to do and n number of peoples then the number of ways to do the work is mxn
How to find number of ways?Here we have given
Number of subjects = 4 that is math, science, art and social science
Number of classes = 4
Therefore the number of way to attending the class is
4x4 = 16
This is the conclusion to the answer.

B. an increase in a company's advertising budget and an increase in their profit
C. an increase in temperature and an increase in ice cream sales
D. an increase in salary and a decrease in sick days
Answer:
A. an increase in the average speed a car travels and a decrease in the time it takes to reach the destination
Step-by-step explanation:
As an increase in the speed of the car decrease the time it takes to reach the destination.
What is correlation?Correlation is the dependence of any statistical relationship between the causal or may be two random variables. It usually indicates the type of association.
As the increase in the car speed will lead to a decrease in the distance and the time it takes to reach the destination. Hence positively correlated.

The base of a pentagonal prism is regular with an apothem of 4 cm. The height of the prism is 16 cm. Find the volume of the prism. Round your answer to the nearest cubic cm.
Answer:
volume ≈ 930 cm³ (nearest cubic cm)
Step-by-step explanation:
The base of the prism which is a pentagon is regular. The apothem which is a line drawn from the center to any side of the pentagon is 4 cm. The height of the prism is 16 cm.
The volume of a prism = Bh
where
B = base area
h = height of the prism
The base of the prism can be divided into 5 congruent triangles.But the base of the triangles is unknown.
The sum of interior angle of a pentagon is 540°. That means each angle is 108° . The triangle divide the angle into 2. Making the 2 base angle as 54° each. The last angle of the triangle at the center is 72°(remember sum of angle in a triangle is 180° which is 54° + 54° + 72° = 180°) .
The angle form the center can be divided by the line of height of the triangles. The angle will then be 36°. Using tangential ratio half of the length of the base of the triangle can be known. Therefore,
tan 36° = opposite/adjacent
tan 36° = opposite/4
opposite = 4 tan 36°
The full base of the triangles = 2(4 tan 36°)
area of each triangle = 1/2 × 2(4 tan 36°) × 4 = 16 tan 36°
Base area of the prism(pentagon) = 5 × 16 tan 36° = 80 tan 36°
Volume of the prism = Bh
where
h = 16 cm
B = 80 tan 36°
volume = 80 tan 36° × 16 = 1280 tan 36° = 1280 × 0.726542528
volume = 929.974435847 cm³
volume ≈ 930 cm³ (nearest cubic cm)

Vaughn is ordering light bulbs for his business. He always orders three extra bulbs. The following shows how the number of light bulbs he orders, y, changes as the number of light bulbs burnt out, x, changes.
Which equation shows this relationship?
A.
y = 3x
B.
y = x + 3
C.
3y = x
D.
y + 3 = x
Answer: D
Step-by-step explanation:
Because if y is the number of light bulbs he orders and he always orders three extra or three more that means that for any number of orders that he makes there will be three more. That three will never change since he always others three more than he ordered.

Question 4
What do you observe about the distances between the three pairs of corresponding vertices for each movement? Based on your observations,
how would you define a translation? How can you extend what you know about the vertices of a shape to all the points on a shape during a
translation?
Answer:
The distances between the three pairs of corresponding vertices for each movement must be equal. That is, if you translate points A to A', B to B', et cetera, the distance between A and A', and B and B' are the same.
A translation is a rigid transformation that moves vertices of a figure a fixed distance.
In a general way, a translation moves all points on a shape a fixed distance.
Answer:
Each distance between the three pairs of corresponding vertices is the same. Based on this observation, a translation is a transformation in a coordinate plane that moves the vertices of a shape a fixed distance. In fact, a translation moves all points on a shape a fixed distance.

hiiii.. please help me with this limit question
Answer:
π
Step-by-step explanation:
Solving without L'Hopital's rule:
lim(x→0) sin(π cos²x) / x²
Use Pythagorean identity:
lim(x→0) sin(π (1 − sin²x)) / x²
lim(x→0) sin(π − π sin²x) / x²
Use angle difference formula:
lim(x→0) [ sin(π) cos(-π sin²x) − cos(π) sin(-π sin²x) ] / x²
lim(x→0) -sin(-π sin²x) / x²
Use angle reflection formula:
lim(x→0) sin(π sin²x) / x²
Now we multiply by π sin²x / π sin²x.
lim(x→0) [ sin(π sin²x) / x² ] (π sin²x / π sin²x)
lim(x→0) [ sin(π sin²x) / π sin²x] (π sin²x / x²)
lim(x→0) [ sin(π sin²x) / π sin²x] lim(x→0) (π sin²x / x²)
π lim(x→0) [ sin(π sin²x) / π sin²x] [lim(x→0) (sin x / x)]²
Use identity lim(u→0) (sin u / u) = 1.
π (1) (1)²
π
Solving with L'Hopital's rule:
If we plug in x = 0, the limit evaluates to 0/0. So using L'Hopital's rule:
lim(x→0) [ cos(π cos²x) (-2π cos x sin x) ] / 2x
lim(x→0) [ -π cos(π cos²x) sin(2x) ] / 2x
-π/2 lim(x→0) [ cos(π cos²x) sin(2x) ] / x
Again, the limit evaluates to 0/0. So using L'Hopital's rule one more time:
-π/2 lim(x→0) [ cos(π cos²x) (2 cos(2x)) + (-sin(π cos²x) (-2π cos x sin x)) sin(2x) ] / 1
-π/2 lim(x→0) [ 2 cos(π cos²x) cos(2x) + π sin(π cos²x) sin²(2x) ]
-π/2 (-2)

Step-by-step explanation:
Every day you play a random song from your library, which includes 200 songs. What is the PROBABILITY that both today and tomorrow the first song that plays is one of your top 10 favorite songs?
To find probability, you must divide the number of events by the number of possible outcomes.
An event (or favorable outcome) is an outcome that is desired.
An outcome is one of many things that could happen.
Since the events occur two times, they must be doubled.
In this case, there are 400 possible outcomes and 20 number of events.
400 ÷ 20 = 0.05The probability of you playing one of your top 10 favorite songs for 2 days is 0.05.

Please answer the question it’s for my math SAT
Answer: D.
This is tricky.
Think of the equation as an equation for a line
where in this case.
[tex]C=5/9(f-32)[/tex]
or
[tex]C=5/9f-5/9(32)[/tex]
You can see the slope of the graph is [tex]5/9[/tex] which means that for an increase of 1 degree Fahrenheit, the increase is [tex]5/9[/tex].
[tex]c=5/9(f)[/tex]
[tex]c=5/9(1)=5/9[/tex]
Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of [tex]9/5[/tex] Degrees Fahrenheit
[tex]c=5/9(f)[/tex]
[tex]1=5/9(f)[/tex]
[tex]f=9/5[/tex]
Since [tex]9/5=1.8[/tex] Statement 2, is true.
The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of [tex]5/9[/tex] degree Fahrenheit is equal to a temperature increase of 1 degree Celsius) is true:
[tex]c=5/9(f)[/tex]
[tex]c=5/9(5/9)[/tex]
[tex]c=25/81[/tex] which is ≠ 1)
An increase of [tex]5/9[/tex] degree Fahrenheit leads to an increase of [tex]25/81[/tex]
not 1 degree, Celsius, and so Statement III is not true.
The final answer is D.

2(5.5x+1)=24
(2)(5.5x)+(2)(1)=24(Distribute)
11x+2=24
Step 2: Subtract 2 from both sides.
11x+2-2=24-2
