Answer:

The perimeter of a rectangle is:

Step-by-step explanation:

Given

The width of a rectangle w =  8n - 8.5 feet

The length of a rectangle l = 8.5n + 10 feet

To determine

The perimeter of a rectangle = P = ?

The perimeter of a rectangle can be determined using the formula

[tex]P = 2(l+w)[/tex]

substitute l = 8.5n + 10 and w = 8n - 8.5

[tex]P=2\left(8.5n+10+8n-8.5\right)[/tex]

   [tex]=2\left(16.5n+10-8.5\right)[/tex]

   [tex]=2\left(16.5n+1.5\right)[/tex]

   [tex]=33n+3[/tex]

Therefore, the perimeter of a rectangle is:

Answer:

She gave 20% away

Step-by-step explanation:

39% as a fraction in its lowest form is 39/100.

To express 39% as a fraction in its lowest form, we need to divide the percentage by 100 and simplify the resulting fraction.

The percentage symbol "%" means "per hundred," so 39% can be written as 39/100.

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD).

Here, the GCD of 39 and 100 is 1, so we divide both numbers by 1:

= 39 ÷ 1 / 100 ÷ 1

= 39/100

Therefore, 39% as a fraction in its lowest form is 39/100.

Answer:

11

Step-by-step explanation:

let the first number be n , then the second number is 5n and

the third number is 5n - 14

Sum the numbers and equate to 41

n + 5n + 5n - 14 = 41

11n - 14 = 41 ( add 14 to both sides )

11n = 55 ( divide both sides by 11 )

n = 5

Thus

first number = 5

second number = 5n = 5 × 5 = 25

third number = 5n - 14 = 5(5) - 14 = 25 - 14 = 11

x = 1/3 and x= -2

Step-by-step explanation:

-5+ and - square root 5^2 -4 times 3 times -2 which is all over 2 times 3

so square rooted 5^2-4 times 3 times -2 is 7 - -5 + and - 7 both over 2 times 3 is -5-7 divided by 2 times 3 and -5 plus 7 divided by 2 times 3 is 1/3 and -5-7 divided by 2 times 3 is -2 therefore leaving x as 1/3 and -2

Answer:

The slope of the graph of machine 1 is: 1/2

The slope of the graph of machine 2 is: 4/5

Step-by-step explanation:

Machine 1

Machine 1 Table is given by

Time (sec)             1         2         3         4

Amount (gal)         0.5      1        1.5       2

Taking two points

Determining the slope between any two points (1, 0.5) and (2, 1)

[tex]\left(x_1,\:y_1\right)=\left(1,\:0.5\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)[/tex]

[tex]m=\frac{1-0.5}{2-1}[/tex]

[tex]m=0.5[/tex]

[tex]m = 1/2[/tex]

Therefore, the slope of the graph of machine 1 is: 1/2

Machine 2

Taking two points from the graph of Machine 2

Determining the between any two points (0, 0) and (10, 8)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(10,\:8\right)[/tex]

[tex]m=\frac{8-0}{10-0}[/tex]

[tex]m=\frac{4}{5}[/tex]
