Each envelope in the class contains the same number of triangles and quadrilaterals. Write an expression that
represents the total number of sides in the room.

Answers

Answer: 3t+4q.

Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.

Step-by-step explanation:

First off, the slope of f(x) is -4.  It is in the form y=mx+b and m=-4.

For g(x), the slope can be calculated from any two points given.  I willuse (1,9) and (3,21) because I like positive numbers.  So, slope is rise over run and it is calculated from (y1-y0)/(x1-x0)  This gives me (21-9)/(3-1) which is equal to 6.  So adding the two slopes: 6+ (-4)=2

Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532

Answers

Answer:

★ Given :

Cost of 50 chickens and 30 ducks = $ 550

Cost of 44 chickens and 36 ducks = $ 532

★ To find :

Cost of chicken and duck

★ Solution :

Assume :

Cost of chicken = x

Cost of duck = y

According to question :

50x + 30y = 550 ......(1)

44x + 36y = 532......(2)

1) - (2)

(50x + 30y) - (44x + 36y) = 550 - 532

50x + 30y - 44x - 36y = 18

6x - 6y = 18

6(x - y) = 18

x - y = 18/6

→ x - y = 3 ....(3)

In equation 1 ,

50 x + 30y = 550

taking 10 common

10(5x + 3y) = 550

5x + 3y = 550/10

5x + 3y = 55

by taking 3 common

3(5/3 x + y) = 55

by dividing 3 on both sides

5/3x + y = 55/3 .....(4)

(3) + (4)

x - y + 5/3 x + y = 3 + 55/3

x + 5/3 x = 64/3

8/3 x = 64/3

by multiplying 3 on both sides

8x = 64

x = 64/8

→ x = 8

→ Cost of chicken = $ 8 ..

by putting value of x in equation 3

x - y = 3

8 - y = 3

y = 8 - 3

→ y = 5

→ Cost of ducks = $5..

Rock, Paper, ScissorsIn this unit, you expanded your Python skills, and now you can really have some fun! In this lab, you are going to create a game that allows the user to play Rock, Paper, Scissors against the computer. If you arent familiar with this classic game, heres how it works: two people (or a person and a computer!) each select either rock, paper, or scissors. The player who chooses the stronger object wins. Here is how the winner is determined:Rock beats scissors because a rock can break scissors.Paper beats rock because paper can cover a rock.Scissors beats paper because scissors can cut paper.Go to https://repl.it/ to write your program.Your program should do the following:Randomly choose rock, paper, or scissors for the computerAsk the user to choose rock, paper, or scissorsCompare the computers choice to the players choiceAnnounce whether the computer or the human wonHere are two hints to help you write this program:Test parts of your program to see if they work before moving on to work on other parts. For example, you will need to have the computer select a random number and then choose for that number to correspond to rock, paper, or scissors. You can write just that portion of the program and then test it by having the program print the word rock, paper, or scissors before you even begin working on the part of the program where the user inputs their choice. (Of course, dont forget to erase the line of code that prints the computers choice when you are finished testingotherwise the game will be just a bit too easy for the user!)On a piece of paper, draw a chart that shows all nine possible outcomes of the game and use that chart to design and test the program. The chart might look like this:TABLE 1 Rock paper scissors outcomes Computer chooses rock Computer chooses paper Computer chooses scissorsUser chooses rockTied gameComputer winsUser winsUser chooses paperUser chooses scissorsRun several tests on your program to be sure that the correct winner is announced.When your program works properly, take a screenshot of your code to turn in. 1.
