Answer:

The perimeter of the rectangle is 27n + 1 feet

Step-by-step explanation:

The formula of the perimeter of the rectangle is P = 2(L + W), where

L is the length of the rectangleW is the width of the rectangle

∵ The width of a rectangle is 7n - 6.5 feet

∴ W = 7n - 6.5 feet

∵ The length of the rectangle is 6.5n + 7 feet

∴ L = 6.5n + 7 feet

→ Substitute W and L in the formula of the perimeter above

∵ P = 2[6.5n + 7 + 7n - 6.5]

→ Add the like terms

∴ P = 2[(6.5n + 7n) + (7 - 6.5)]

∴ P = 2[13.5n + 0.5]

→ Multiply the terms in the bracket by 2

∴ P = 27n + 1

∴ The perimeter of the rectangle is (27n + 1) feet

Using the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

On average, Shawnee drinks 1/2 of a 6 ounce glass of water in 2/3 hour. How much water does she drink in an hour?

Answers

Answer:

1/2 of 6 = (1/2)*6 = 0.5*6 = 3

Shawnte drinks 3 ounces of water in 2/3 hrs.

3 oz = 2/3 hr

3*(3 oz) = 3*(2/3 hr) .... multiply both sides by 3

9 oz = 2 hrs

She drinks 9 ounces of water in 2 hrs

9/2 oz = 2/2 hrs .... divide both sides by 2

4.5 oz = 1 hr

She drinks 4.5 ounces of water in 1 hour.

Step-by-step explanation:

A pentagon's sum of interior angles is 540 degrees.

Now, we can set up an equation.

(4x - 57) + (3x + 15) + 4x + (2x - 3) (3x + 25) = 540

Combine similar terms

16x - 20 = 540

16x = 560

x = 35

The answer would be 35.

Answers

Answer:

interior angle of a heptagon = 900 degrees

900 = 4x + (3x + 60)

840 = 7x

840/7 = 120

X = 120

120 X 4 = 480

120 X 3 = 360

480 + 360 + 60 = 900

10 15 11 13 11

If you had to use one number to tell someone how long it took Jin Ya to get to school, what would you say?

Answer:

11 minutes or 12 minutes

Step-by-step explanation:

Given:

10 15 11 13 11

Required

Determine one number that summarizes the 5 numbers

First, one can use the mean to get the summary of the numbers.

The mean is calculated as:

[tex]Mean = \frac{Sum\ of\ observation}{Number\ of\ observation}[/tex]

[tex]Mean = \frac{10 + 15 + 11 + 13 + 11}{5}[/tex]

[tex]Mean = \frac{60}{5}[/tex]

[tex]Mean = 12[/tex]

Another number that summarizes the numbers is the mode of the distribution.

[tex]Mode = Highest\ Occurring\ Value[/tex]

So, in this case:

[tex]Mode = 11[/tex]

Hence, you can either use 11 minutes or 12 minutes.
