7) A container is 1/3 full of water and 1/4 full of oil. What fraction of the container is empưy?​

Answers

Answer:

[tex]Empty = \frac{5}{12}[/tex]

Step-by-step explanation:

Given

[tex]Water = \frac{1}{3}[/tex]

[tex]Oil = \frac{1}{4}[/tex]

Required

The fraction that is empty

The constituent of the water can be represented as:

[tex]Water + Oil + Empty = 1[/tex]

Make Empty the subject

[tex]Empty = 1 - Water - Oil[/tex]

Substitute values for Water and Oil

[tex]Empty = 1 - \frac{1}{3} - \frac{1}{4}[/tex]

Take LCM

[tex]Empty = \frac{12 - 4 - 3}{12}[/tex]

[tex]Empty = \frac{5}{12}[/tex]

Monica has a cylindrical container full of marbles. The container is shown below.
10 cm
The height of the container is approximately 12 centimeters. Which is closest to
the volume of Monica's container, in cubic centimeters?

Answers

Answer:

Area of a circle is  pi * [tex]r^{2}[/tex]

then multiply that by the height

Step-by-step explanation:

diameter = 10

radius is   diameter / 2

r = 10/2 = 5

A = pi * [tex]5^{2}[/tex]

A = 78.5398

height * A = volume

12 * 78.5398 = 942.477

A record with a diameter of 12 inches rotates at 33 revolution per minute find the angular speed of the record in radians per second

Answers

9514 1404 393

Answer:

  1.1π radians/second

Step-by-step explanation:

Each revolution is 2π radians, and there are 60 seconds in a minute. The rotation rate is ...

  (33 rev/min)×(2π rad/rev)×(1 min)/(60 sec) = 66π/60 rad/sec

  = 1.1π rad/sec

The angular speed is 1.1π radians per second.

What is the slope of the line through (- 3, 2) and (0, 1) ? Ill give 100 points to whoever gives me the CORRECT answer. I keep getting syntax errors when I do the "add:" part. Can someone walk me through this code?Part A One of the biggest benefits of writing code inside functions is that we can reuse the code. We simply call it whenever we need it! Lets take a look at a calculator program that could be rewritten in a more reusable way with functions. Notice that two floats (decimal numbers, but they can also include integers) are inputted by the user, as an operation that the user would like to do. A series of if statements are used to determine what operation the user has chosen, and then, the answer is printed inside a formatted print statement. num1 = float(input("Enter your first number: ")) num2 = float(input("Enter your second number: ")) operation = input("What operation would you like to do? Type add, subtract, multiply, or divide.") if operation == "add": print(num1, "+", num2,"=", num1 + num2) elif operation == "subtract": print(num1, "-", num2,"=", num1 - num2) elif operation == "multiply": print(num1, "*", num2,"=", num1 * num2) elif operation == "divide": print(num1, "/", num2,"=", num1 / num2) else: print("Not a valid operation.") Your job is to rewrite the program using functions. We have already looked at a function that adds two numbers. Using that as a starting point, we could call the add function from within our program in this way: if operation == add: result = add(num1, num2) print(num1, "+", num2,"=",result) Now its your turn to do the following: Type all of the original code into a new file in REPL.it. Copy the add function from the unit and paste it at the top of your program. Write 3 additional functions: subtract, multiply, and divide. Pay careful attention to the parameters and return statement. Remember to put the three functions at the top of your Python program before your main code. Rewrite the main code so that your functions are called. Part B There are many different ways that a user could tell us that he or she would like to add two numbers in our calculator program. The user could type add, Add, ADD, or +, to name a few possibilities.
