A shop owner increases some prices by 50%.
This is the same as:

choose one
multiplying the original price by 0.5, 1.5, 2.5 or 150?

Answers

1.5 is correct answer

The another way is same as;

Multiplying by 0.5 with original price.

Here,

A shop owner increases some prices by 50%.

We have to find another method to find same condition.

What is the percentage?

A relative value indicating hundredth parts of any quantity is called the percentage.

Now,

A shop owner increases some prices by 50%.

Let the original price is x.

Then, The increase value = x * 50% = x * 50/100 = 0.5x

Hence, To find the increase value we have to multiply by 0.5 with original price.

Step-by-step explanation:

Two events A and B are said to be independent if the fact that one event has occurred does not affect the probability that the other event will occur. If whether or not one event occurs does affect the probability that the other event will occur, then the two events are said to be dependent.

for every 5 red cars there are 8 black cars. If there are 24 more black cars than red cars how many total vehicles are there​

Answers

Answer:

15 red cars + 24 black cars = 38

The total vehicles are 104.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

For every 5 red cars there are 8 black cars.

And, There are 24 more black cars than red cars.

Here, For every 5 red cars there are 8 black cars.

Hence, Number of red cars = 5x

Then, Number of red cars = 8x

And, There are 24 more black cars than red cars.

Hence, We get;

⇒ 24 + 5x = 8x

Solve for x as;

⇒ 24 = 8x - 5x

⇒ 24 = 3x

⇒ x = 8

Thus, Number of total vehicles = 5x + 8x

                                                = 5×8 + 8×8

                                                = 40 + 64

                                                = 104

I don’t know how to do this help me

Answers

Answer:

The answer: ( 2 , -3 )

Step-by-step explanation:

equation (1): 5x + 2y = 4

equation (2): y = x - 5

step1: sub ( x-5 ) for y in equation 1:

5x + 2 ( x-5 ) = 4

step2: multiply 2 by the bracket:

5x + 2x - 10 =4

step3: add the x term together:

7x - 10 = 4

step4: add 10 for both sides:

7x = 14

step5: divide by 7 from both sides to get the value of x:

x = 2

step6: sub ( 2 ) for x in equation 2 :

y = x - 5

y = 2 - 5

step7: simplify to get the value of y:

y = -3

So the answer is:

x = 2   and   y = -3

What is the area of the figure below?

Answers

Answer:

104

Explanation:

1. Split the figure by the line the larger portion creates.

2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.

3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.

4. Now, we simply do 6 · 8 = 48. Almost there!

5. Finally, add the values of the left side and the right side (48 + 56 = 104)

6. YOUR ANSWER IS 104 cm squared.

Step-by-step explanation:

It's a little hard to see but I'm pretty sure it's B because we're looking for a graph that has a slope of -2 so it couldn't be A or D because they have positive slopes since they are pointing up. That leaves B and C. I can't really see but C doesn't look like it has a slope of -2, so I went with B because it has a y-intercept of 3 and looks like it has a slope of -2.

A)Only Tom is correct
B)Only Katie is correct
C)They both are correct
D)Neither are correct

Answers

Answer:

B

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 17 - 22 = 12 - 17 = 7 - 12 = 2 - 7 = - 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 22 and d = - 5, then

[tex]a_{n}[/tex] = 22 - 5(n - 1) = 22 - 5n + 5 = 27 - 5n → B

6 and -6 are at the same distance from ____ on the number line. Build a class and a driver for use in searching your computers secondary storage (hard disk or flash memory) for a specific file from a set of files indicated by a starting path. Lets start by looking at a directory listing. Note that every element is either a file or a directory.Introduction and DriverIn this assignment, your job is to write a class that searches through a file hierarchy (a tree) for a specified file. Your FindFile class will search a directory (and all subdirectories) for a target file name.For example, in the file hierarchy pictured above, the file "lesson.css" will be found once in a directory near the root or top-level drive name (e.g. "C:\") . Your FindFile class will start at the path indicated and will search each directory and subdirectory looking for a file match. Consider the following code that could help you build your Driver.java:String targetFile = "lesson.css";String pathToSearch ="C:\\WCWC"; FindFile finder = new FindFile(MAX_NUMBER_OF_FILES_TO_FIND);Finder.directorySearch(targetFile, pathToSearch);File SearchingIn general, searching can take multiple forms depending on the structure and order of the set to search. If we can make promises about the data (this data is sorted, or deltas vary by no more than 10, etc.), then we can leverage those constraints to perform a more efficient search. Files in a file system are exposed to clients of the operating system and can be organized by filename, file creation date, size, and a number of other properties. Well just be interested in the file names here, and well want perform a brute force (i.e., sequential) search of these files looking for a specific file. The way in which well get file information from the operating system will involve no ordering; as a result, a linear search is the best we can do. Wed like to search for a target file given a specified path and return the location of the file, if found. You should sketch out this logic linearly before attempting to tackle it recursively.FindFile Class InterfaceFindFile(int maxFiles): This constructor accepts the maximum number of files to find.void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in.int getCount(): This accessor returns the number of matching files foundString[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.RequirementsYour program should be recursive.You should build and submit at least two files: FindFile.java and Driver.java.Throw an exception (IllegalArgumentException) if the path passed in as the starting directory is not a valid directory.Throw an exception if you've found the MAX_NUMBER_OF_FILES_TO_FIND and catch and handle this in your main driver. Your program shouldn't crash but rather exit gracefully in the unusual situation that we've discovered the maximum number of files we were interested in, reporting each of the paths where the target files were found.The only structures you can use in this assignment are basic arrays and your Stack, Queue, or ArrayList from the previous homeworks. Do not use built-in data structures like Java's ArrayList. To accomplish this, put in the following constructor and method to your ArrayList, Stack, or Queue:public ArrayList(Object[] input) { data = input; numElements = input.length;}public Object get(int index) { return data[index];} Which statement accurately describes viscosity?
