the floors of houses in japan are traditionally covered by tatami. tatami are rectangle shaped straw mats that measure about 6 feet by 3 feet. if a room is 48 feet by 24 feet, how many tatami are needed to cover the floor
Answers
Oh yikes, this one hasn't been answered in 4 years..
Let's get the area of one tatami, then the one of the floor.
Tatami area: 6*3 = 18 sq. feet
Floor area: 48*24 = 1152 sq. feet
To know how many tatami are needed, we need to divide the floor area by the tatami area:
1152/18 = 64
You'd need 64 tatami to cover the floor

Suppose that the manufacturer of a gas clothes dryer has found that when the unit price is p dollars, the revenue R in dollars is
R(p)= -4p^2+4000p
What unit price should be established for the dryer to maximize revenue?
What is the maximum revenue?
Answers
The function that is given is a quadratic equation and the graph would be an upside down parabola.
Therefore, the maximum revenue would be at the vertex of the parabola.
To find the vertex, we can use the expression -b/2a to find the x-value.
It would be -4000/2(-4) = 500
Now, input 500 for p and you will get a revenue of 1,000,000.
Answer:
p=$500 is the unit price to get maximum revenue
Maximum revenue = $1,000,000
Step-by-step explanation:
the revenue R in dollars is:
[tex]R(p)= -4p^2+4000p[/tex]
To find out the unit price to get maximum revenue we find out the vertex
In the given quadratic equation a=-4 and b= 4000
Formula to find out the x coordinate of vertex is
[tex]x=\frac{-b}{2a}[/tex], plug in the values
[tex]x=\frac{-4000}{2(-4)}[/tex]
x=500
So p=$500 is the unit price to get maximum revenue
Now we find the maximum revenue . Plug in 500 for p in the given equation
[tex]R(p)= -4p^2+4000p[/tex]
[tex]R(500)= -4(500)^2+4000(500)[/tex]
R(500)=1000000
Maximum revenue = $1,000,000

A supermarket conducts a survey to find the approximate number of its customers who like apple juice. What is the population of the survey?
Answers
In a survey conducted by a supermarket to find out how many customers like apple juice, the population of the survey would be all customers of the supermarket. The population in a survey defines the group the research wants to gain information about and determine the applicability of the findings.
Explanation:In the context of survey research, a population refers to the entire group about which information is wanted. In your scenario, where a supermarket is conducting a survey to find out how many customers like apple juice, the population of the survey would be all customers of the supermarket. It's important to identify the population in a survey because it helps determine the scope of the study and how broadly the findings can be applied.
For example, if you were a marketing manager for an electronics chain store wanting information about the ages of its customers, the population would also be all customers of the store. Similarly, if a radio station wants to know its listeners' preferences, the population would be all listeners of that station. The aim is to collect data that is representative of this population, be it through sampling or other data collection methods.

The probability of reaching into a drawer without looking and selecting a black sock is 5/6. If there are a total of 24 socks in the drawer, how many socks in the draw are black? Please help me :c
Answers
The probability of selecting a black sock is 5/6 and there are 24 socks in total. By setting up and solving a simple equation, we find that there are 20 black socks in the drawer.
Explanation:This question is about the concept of probability in mathematics. The probability of an event occurring is calculated by the number of desired outcomes divided by the total number of possible outcomes. In this case, we are given that the probability of reaching into a drawer without looking and magically pulling out a black sock is 5/6. With a total of 24 socks in the drawer, to figure out how many socks are black, we can set up a simple equation where x represents the number of black socks. Thus, x/24 = 5/6. Solving this equation, we get x = (5/6) * 24, which simplifies to x = 20. So, there are 20 black socks in the drawer. That's indeed a lot of black socks!

1. All numbered streets runs parallel to each other. Both 3rd and 4th Streets are intersected by King Ave. as shown:
(a) Suppose a car is traveling east on 4th Street and turns onto King Avenue heading northeast. What is the measure of the angle created by the car's turning? Explain your answer.
(b) Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.
(c) Suppose a car is traveling northeast on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.
Answers
As shown in the diagram attached, the angle made between 4th street and king avenue if car is traveling from the west side is 75°.
when the car is travelling from the east side and is supposed to take a turn towards north east lets call the angle it makes with the turn as x.
4th street is a straight road, therefore straight line
and sum of angles of a straight line is 180°.x and 75 are supplementary angles.
Therefore x + 75° = 180°
x = 105°
therefore the angle it makes in the turn is 105°
Q2)
When the car is travelling south west and turns left towards 3rd street, the angle it makes is termed as y. when 2 parallel lines are cut by a transversal, x° and y° are corresponding angles.
This means that the angle at which transversal cuts 3rd street and 4th street to the left are both equal. these are called corresponding angles.
this means that x = y
as derived in the previous question, x = 105°,
hence, y = 105°.
Q3)
When the car is travelling north east and turns right onto 3rd street, lets name the angle it makes with the turn as z.
angles y and z are called vertically opposite angles. When 2 straight lines cut each other, the opposite angles formed are equal to each other.
Therefore y = z.
as derived in the previous question y = 105°.
since y = z
hence, z = 105°
Answer:
the guy is right except number 2
Step-by-step explanation:
if the car turns left that means it went west and since 4th and 3rd street are parallel and King Ave. is a transparent then street 4 and 3 have the same angles. y is 75 and a vertical that means the car makes a 75 degrees angles .

How many playlists can we make with 38 songs if we can repeat 5 songs in each playlist? Use the permutation or combination formula if applicable.
Answers
Final answer:
The number of playlists that can be created with 38 songs allowing for the repetition of 5 songs is calculated using combinations with repetition, resulting in a total of 850,668 possible playlists.
Explanation:
The question relates to the number of different ways we can create playlists from 38 songs, with the possibility of repeating 5 songs in each playlist. To calculate the number of different playlists that can be made by repeating songs, we need to use combinations with repetition. This is a concept in combinatorics which allows for the selection of items with replacements.
We can represent the problem with a formula used for combinations with repetition: (n + r - 1) choose r, where n is the total number of options (in this case, 38 songs) and r is the number of choices to make (in this case, repeating 5 songs). The formula becomes (38 + 5 - 1) choose 5, which simplifies to 42 choose 5. Using the combination formula, we can compute the total number of possible playlists as follows:
C(42, 5) = 42! / (5!(42-5)!) = 42! / (5!37!) = 850,668
This number represents the total number of playlists we can create with 38 songs, allowing for the repetition of 5 songs on each playlist.
The diameter of a small gear is 16cm. This is 2.5cm more than 1/4 of the diameter of a larger gear. What is the diameter of the larger gear?
Answers
To find the diameter of the larger gear, we set up an equation based on the information that the smaller gear's diameter is 2.5cm more than a quarter of the larger gear's diameter. Solving this, the diameter of the larger gear is found to be 54cm.
The student has asked for the diameter of a larger gear when given that the diameter of a smaller gear is 16cm, which is 2.5cm more than one quarter of the larger gear's diameter. To find the diameter of the larger gear, we can set up an equation where d represents the diameter of the larger gear.
According to the question:
16cm = 1/4d + 2.5cm
To solve for the diameter d, we subtract 2.5cm from both sides and then multiply by 4:
The diameter of the larger gear is therefore 54cm.
A square has side lengths of 7 inches. Find the length of the square’s diagonal.
Answers
7•7=49
7•7=49
49+49= 98
Now let’s find the square root of 98. I usually go to the hundredths place since I know 98 doesn’t have a perfect square.
9.9•9.9= 98.01 (the hundredths place rounded to that)
So the length of the square’s diagonal is about 9.9 inches.
Final answer:
The length of the square's diagonal with side lengths of 7 inches is found using the Pythagorean theorem, leading to a diagonal of approximately 9.899 inches.
Explanation:
To find the length of the square's diagonal when the side lengths are 7 inches, we can use the Pythagorean theorem. The diagonal of a square creates two right triangles, with the diagonal being the hypotenuse. You can think of this as half of the square divided along the diagonal. Each of these triangles has two legs that are each equal to the side of the square and a hypotenuse which is the diagonal we want to find.
The formula for the Pythagorean theorem is a² + b² = c², where a and b are the legs of the right triangle, and c is the hypotenuse. Since the legs are both 7 inches (the side length of the square), we have:
7² + 7² = c²
49 + 49 = c²
98 = c²
This simplifies to:
c = √98
c ≈ 9.899 inches (rounded to three decimal places)
Therefore, the diagonal of the square is approximately 9.899 inches long.

B. More than one unique triangle exists with the given angle measures.
C. No triangle exists with the given angle measures.
D. A triangle can be drawn with more than one acute angle.
Answers
The first thing to check is the sum of the angles. 32 + 51 + 97 = 180. Therefore, the sides equal 180 and we can have a triangle because all triangles have exactly 180 degrees.
Second, the number of triangles with these measures is endless. Imagine taking the initial triangle and doubling the size. The angles don't change but the triangle does. We could keep doubling the size forever.

A. 36 inches
B. 18 inches
C. 12 inches
D. 6 inches
Answers
Answer
The Answer to your question in 6
Step-by-step explanation:
The formula to find the area is
r^2 * pi = area
we know that the area is 113.04 and pi = 3.14
so
x^2 * 3.14 = 113.04
divide both sides by 3.14
x^2 = 36
now for the final step we need to find the root of both sides
√x^2 = √36
x = 6
so the radius is 6.

Step-by-step explanation:
A paleontologist uncovers a fossil of a saber-toothed cat in California. He analyzes the fossil and concludes that the specimen contain 15% of its original carbon-14. Carbon-14 has a half-life of 5730 years. Use carbon-14 dating to determine the age of the fossil.
Answers
Carbon-14 dating is used to determine the age of fossils by comparing the amount of carbon-14 in the specimen to the amount in the atmosphere. The half-life of carbon-14 is 5730 years, and by analyzing the percentage of carbon-14 remaining, the age of the fossil can be calculated.
Explanation:Carbon-14 dating is used to determine the age of fossils. Carbon-14 (14C) is a radioisotope that is present in living organisms while they are alive, and it starts to decay after they die. The half-life of carbon-14 is 5730 years, which means that after this time period, half of the original carbon-14 will have decayed.
In the case of the saber-toothed cat fossil, the paleontologist analyzed the specimen and found that it contained 15% of its original carbon-14. By comparing this percentage to the amount of carbon-14 in the atmosphere, which is known, they can determine the age of the fossil.
Since carbon-14 dating is accurate up to about 50,000 years, this method is suitable for dating the fossil. The age of the fossil can be calculated by considering the amount of carbon-14 remaining and the known half-life of the isotope.
