Answer:

Shaded area is 55 units²

Step-by-step explanation:

Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction). The area of this larger rectangle is

(10 units)(7 units) = 70 units². The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²

Subtract the latter from the former, obtaining the net area

70 units² - 15 units² = 55 units²

PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?

Answers

Answer:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.

Step-by-step explanation:

The given is,

One train travels at an average speed of 80 km/hr

The other travels at an average speed of 70 km/hr

Step:1

Formula to calculate the distance traveled by two trains,

Distance traveled by two trains = (Rate of speed of train one +

Rate of speed of other train) × Time

From the given the above equation becomes,

Let, h = Time taken to each the distance

50 = ( 80 + 70 ) h

50 = (150) h

= 0.3333 hours

= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )

h = 20 minutes

Step:2

Check for solution,

From equation (1),

50 = ( 80+70 ) (0.3333)

50 = (150)(0.3333)

50 = 50

Result:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Here is to my last q

Answers

Mode: value that occurs most
Mean: average (add all values then divide by the amount of number)
Median: middle number

Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85

Which statement matches?

Solution: D

Answer: D (Mean is 85)

Explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

Median: find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

D is the correct answer

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!

No, It is not true

Step-by-step explanation:

First of all, we should have a number in the tenths place, and we don't.

Also, in the hundredths place, we should have 9, not 4.

And finally, the answers should be 0.195, not 0.042.

Answer:

This is False

You want to add it up as if there wasnt any decimal than you want to put the decimals back 3 spots

120° is an exterior angle of the triangle , then

37x + 9 = 120 ( subtract 9 from both sides )

37x = 111 ( divide both sides by 37 )

Find the area of the figure.

Answers

if i’m not mistaken it should be 55 because if you find the area of the whole triangle and subtract the mini rectangle you should get the shape

i’m pretty sure the answer is 15. this is because i split the triangle into 2 parts, then i multiplied 5x4 for the first triangle which equals 20, but then u have to divide it by 2 bc the formula for a triangle is A=1/2 (b x h) so then the answer for the first triangle is 10. now you have to do it to the other little triangle which gives u 5. at this point you have to add 10+5 which gives you 15. therefore the answer for this question is 15. i hope this helps!

For this exercise, you will complete the TicTacToe Board that we started in the 2D Arrays Lesson.We will add a couple of methods to the TicTacToe class.To track whose turn it is, we will use a counter turn. This is already declared as a private instance variable.Create a getTurn method that returns the value of turn.Other methods to implement:printBoard()- This method should print the TicTacToe array onto the console. The board should include numbers that can help the user figure out which row and which column they are viewing at any given time. Sample output for this would be: 0 1 20 - - - 1 - - - 2 - - - pickLocation(int row, int col)- This method returns a boolean value that determines if the spot a user picks to put their piece is valid. A valid space is one where the row and column are within the size of the board, and there are no X or O values currently present.takeTurn(int row, int col)- This method adds an X or O to the array at position row,col depending on whose turn it is. If its an even turn, X should be added to the array, if its odd, O should be added. It also adds one to the value of turn.checkWin()- This method returns a boolean that determines if a user has won the game. This method uses three methods to make that check:checkCol- This checks if a player has three X or O values in a single column, and returns true if thats the case.checkRow - This checks if a player has three X or O values in a single row.checkDiag - This checks if a player has three X or O values diagonally.checkWin() only returns true if one of these three checks is true.public class TicTacToeTester{ public static void main(String[] args) { //This is to help you test your methods. Feel free to add code at the end to check //to see if your checkWin method works! TicTacToe game = new TicTacToe(); System.out.println("Initial Game Board:"); game.printBoard(); //Prints the first row of turns taken for(int row = 0; row < 3; row++) { if(game.pickLocation(0, row)) { game.takeTurn(0, row); } } System.out.println("\nAfter three turns:"); game.printBoard(); }}public class TicTacToe{ private int turn; private String[][] board = new String[3][3]; public TicTacToe() { for(int i = 0; i < 3; i++) { for(int j = 0; j < 3; j++) { board[i][j] = "-"; } } } //this method returns the current turn public int getTurn() { return turn; } /*This method prints out the board array on to the console */ public void printBoard() { } //This method returns true if space row, col is a valid space public boolean pickLocation(int row, int col) { return true; } //This method places an X or O at location row,col based on the int turn public void takeTurn(int row, int col) { } //This method returns a boolean that returns true if a row has three X or O's in a row public boolean checkRow() { return true; } //This method returns a boolean that returns true if a col has three X or O's public boolean checkCol() { return true; } //This method returns a boolean that returns true if either diagonal has three X or O's public boolean checkDiag() { return true; } //This method returns a boolean that checks if someone has won the game public boolean checkWin() { return true; }} Read the section "No More Human Error."Which sentence from the section shows why robot referees are better than human referees?ASimilar systems could handle calls in many different sports.BIt shouldn't have any favoritism toward certain teams or players.CFor example, they can manage a player who's upset or angry.DTennis matches usually have up to nine umpires.
