Answer:

2,160 minutes

Further explanation

Given:

Frances is sewing a border around 2 rectangular tablecloths that each measure 9 feet long by 6 feet wide.
It takes her 3 minutes to sew on 1 inch of the border.

Question:

How many minutes will it take her to complete her sewing project?
Write an expression, and then solve it.

The Process:

The following are the steps to form the expression.

Perimeter of a rectangle: $\boxed{2 * (9 + 6)}$
The total perimeter of the two rectangles: $\boxed{2 * 2 * (9 + 6)}$
Converting feet to inches: $\boxed{2 * 2 * (9 + 6) * 12}$
She takes 3 minutes to sew on 1 inch of the border of a tablecloth, therefore we can write an expression as follows: $\boxed{\boxed{ \ 2 * (2 * (9 + 6 )) * 12 * 3 \ }} \ in \ minutes$

Let us solve the expression.

$\boxed{\ 2 * (2 * (9 + 6 )) * 12 * 3 \ } \ in \ minutes$

$\boxed{\ = 2 * (2 * 15) * 12 * 3 \ } \ in \ minutes$

$\boxed{\ = 2 * 30 * 12 * 3 \ } \ in \ minutes$

$\boxed{\ = 720 * 3 \ } \ in \ minutes$

Thus she takes 2,160 minutes to complete her sewing project.

The following are the complete steps.

Step-1:calculating the total perimeter of the border around 2 rectangular tablecloths

Recall the perimeter of a rectangle.

$\boxed{ \ Perimeter = 2 * (length + width) \ }$

$\boxed{ \ Perimeter = 2 * (9 + 6) \ }$

$\boxed{ \ Perimeter = 2 * 15 \ }$

Hence the perimeter of a rectangular tablecloth is 30 feet.

So, the total perimeter of the border around 2 rectangular tablecloths is $\boxed{30 \ feet * 2 = 60 \ feet}$

Step-2:converting feet to inches

Recall that $\boxed{1 \ feet = 12 \ inches \ }$

Let us convert 60 feet to inches.

$\boxed{\ = (12 \ inches)/(1 \ feet) * 60 \feet \ }$

$\boxed{\ = 720 \ inches \ }$

Step-3:calculating minutes will it take her to complete her sewing project

She takes 3 minutes to sew on 1 inch of the border of a tablecloth. There are 2 rectangular tablecloths.

$\boxed{ \ = (3 \ minutes)/(1 \ inch) * 720 \ inches \ }$

$\boxed{ \ = 3 * 720 \ minutes \ }$

$\boxed{\boxed{ \ 2,160 \ minutes \ }}$

Thus she takes 2,160 minutes to complete her sewing project.

Answer 2

Answer: The perimeter of a rectangle is - 2 x (length + breadth).

Also, 1 feet = 12 inches.

So, the dimensions of the tablecloth are 108 inches long by 72 inches wide. So, the total perimeter of the table cloth is --> 2 x (108 + 72) = 360 inches.

So, time taken for 1 tablecloth = 360 x 3 = 1080 minutes.

And, Time taken for 2 tablecloths = 1080 x 2 = 2160 minutes.

So, to complete her sewing project, Frances will take a total of 2160 minutes (36 hours).

A minimum of a high school wrestling mat is 1444 square feet. what is the length of the mat?

Answers

The length of a wrestling mat with an area of 1444 square feet could be approximately 38 feet, if assuming the mat to be a square. However, without more specific information, the exact dimensions could vary while maintaining the same area.

Without additional information, we can't determine the exact length of the wrestling mat. However, if we assume the mat is a perfect square, where the length and width are equal, then we can find the side length by taking the square root of the area.

To find the square root, you can use a calculator and input 1444. You'll find that the square root of 1444 is approximately 38 feet. This would be the length of each side if the wrestling mat is a square.

Keep in mind that this is an approximation. The actual wrestling mat could have different dimensions but still have an area of 1444 square feet. For instance, it could be rectangular rather than square.
