The coastline of the United States is 12,383 miles long. Canada's coastline is 113,211 miles longer than the coastline of the United States. How long is the coastline of Canada?

Answers

Answer 1

Answer: So this is basically an addition word problem. Let's start with what we know: the United States Coastline is 12,383 miles long and Canda's Coastline is 113,211 miles LONGER. Whenever there is a synonym for "more", that tends to be addition. So add 12,383 to 113,211 in order to get 125,594.

Think about making a factor rainbow for drawing rectangles to list all the factors of a number. how are the two methods alike? how are they different? ( pls tell me the answer)

Answers

Answer:

HOPE IT HELPS! PLS mark branliest

Step-by-step explanation:

Creating a "factor rainbow" and listing the factors of a number by drawing rectangles are two visual methods used to understand and identify the factors of a given number.

Similarities:

Visual Representation: Both methods rely on visual aids to help understand and identify factors.

Systematic Approach: They both provide a structured way to identify factors. They guide you through a process to ensure you don't miss any factors.

Differences:

Nature of Representation:

Factor Rainbow:

A factor rainbow is typically a circular or semi-circular diagram. The number is placed at the top, and its factors are shown as radii (lines from the center to the edge) of the circle.

Each factor is represented as an arc.

It's a visual representation that helps to see the pairs of factors and how they relate to each other.

Rectangles:

Drawing rectangles involves creating a rectangular grid or array, with the number of rows and columns corresponding to the potential factors.

Each rectangle represents a possible combination of factors, and the number of rectangles gives a visual representation of how many factors there are.

It's a more structured and organized representation.

Space Utilization:

Factor Rainbow:

It might be more space-efficient compared to drawing rectangles because it uses a circular or semi-circular layout.

Rectangles:

Depending on the size of the number and the number of factors, drawing rectangles can require a larger space as it involves creating a grid.

Ease of Identification:

Factor Rainbow:

It's useful for visualizing relationships between factors. It's good for understanding how factors pair up.

However, it may not be as straightforward for identifying all factors, especially for larger numbers.

Rectangles:

It provides a systematic method for identifying all factors. You can easily count the number of rectangles to find the total number of factors.

Flexibility for Visualization:

Factor Rainbow:

It can be a bit more flexible in terms of visualization as it allows for curvature in its representation.

Rectangles:

It's a very structured method, which may not lend itself to certain numbers as well (e.g., prime numbers).

In summary, both methods serve the purpose of visualizing factors, but they do so in different ways. The factor rainbow emphasizes relationships between factors, while drawing rectangles provides a structured method for systematically identifying all factors. The choice of method may depend on personal preference and the specific number being analyzed.

Answer:

Both the factor rainbow and drawing rectangles are methods used to visually list all the factors of a given number.

Similarities:

Visual Representation: Both methods provide a visual representation of the factors of a number, making it easier to understand and identify the factors.

Systematic Organization: Both methods organize the factors in a systematic way, allowing for a clear and organized display of the factors.

Differences:

Representation Style:

A factor rainbow is a simple visual representation where factors are listed in an arched shape, starting from 1 and extending to the given number.

Drawing rectangles involves creating a grid or rectangles to represent the factors, where the dimensions of the rectangles correspond to the pairs of factors.

Geometric vs. Linear:

Drawing rectangles uses a geometric representation (rectangles) to display the factors.

Factor rainbow is a linear representation, showcasing the factors in an arched arrangement.

Flexibility and Versatility:

Drawing rectangles allows for the demonstration of the commutative property of multiplication (e.g., for factors 6 and 10, you can create a rectangle with dimensions 6x10 or 10x6).

Factor rainbow is a simpler method and may not easily demonstrate the commutative property.

In summary, both methods serve the purpose of visually representing the factors of a number, but they use different styles and structures for this representation. Drawing rectangles involves a geometric approach, while the factor rainbow uses a linear arrangement. Drawing rectangles also offers additional versatility in illustrating the commutative property of multiplication.

What is the solution to 48 - 3x) > 6x-8?

Answers

Answer:

Step-by-step explanation:

(48-3x)>6x-8

48-3x>6x-8

Collecting like terms, we have

-3x-6x>-8-48

Moving variables or numbers from one side to the other changes the sign it carries

-9x>-56

Divining both sides by -9 changes the inequality sign

x<56/9

x<6.22

During 2002 a town had a total snowfall of 92 inches, which was an increase of 15% from the previous year. What was the total snowfall in the previous year?

Answers

1.) Divide 92 by 100 so that it can be 100 pieces or 100% 92/100= 0.92
2.) Multiply the 15% be 0.92 to get how much more inches in snow that they got this year than last year. 15 X 0.92= 13.8
3.) Since we have how much more inches of snow they got all we need to do is subtract 13.8 from 92. 92-13.8= 78.2
4.) In the previous year the town had received 78.2in of snow.
I hope this helps :)

The town received 78.2 inched of snow the previous year

Which statement best explains whether y = 2x − 3 is a linear function or a nonlinear function? It is a linear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are on a straight line. It is a nonlinear function because the graph contains the points (0, −3), (1, −1), (2, 1), which are not on a straight line. It is a linear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are on a straight line. It is a nonlinear function because the graph contains the points (−3, 0), (−1, 1), (1, 2), which are not on a straight line.
