The formula for perimeter is 2l+2w. Since we know l=(w-4)-9, we can substitute this into the formula.

l=w-13

2(w-13)+2w=143

2w-26+2w=143

4w=169

w=42.25 units

Hope this helps!

This would have to apply for a certain height compared to a weight or vice versa. I'm 5'8'' and for me that would mean I would have a healthy weight of 140 lbs.

Tina is planning to fence in an area for her dog. She wants to create a rectangular area of 1,600 square feet for her pet and ca
castortr0y [4]

The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft

<h3 />

<h3>Area of a rectangle:</h3>
  • area = lw

where

l = length

w = width

She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,

  • area = 1600 ft²

lw = 1600

Therefore,

perimeter = 160 ft

Then,

perimeter of rectangle = 2(l + w)

160 = 2(l + w)

l + w = 80

Let's combine the equations

lw = 1600

l + w = 80

l = 80 - w

Therefore,

w(80 - w) = 1600

80w - w² = 1600

Therefore,

w² - 80w + 1600 = 0

w² - 40w - 40w + 1600 = 0

w(w - 40) - 40(w - 40) = 0

(w - 40)(w - 40) = 0

w = 40 or 40

Therefore, the dimensions can be calculated as follows:

lw = 1600

40l = 1600

l = 1600 / 40

l = 40 ft

Therefore, the dimensions are 40ft by 40 ft

the second term in a geometric sequence is 20. the fourth term in the same sequence is 45/4 or 11.25. what is the common ratio
slega [8]
4th term / second term  = a1r^3 / a1r = r^2

so r^2  = 45/4 / 20 = 45/80  = 9/16

so r = sqrt 9/16  = 3/4  answer

Answer:

450, 566 ; 450,082 ; 405,987

Step-by-step explanation:

Number of visitors in may = 450,082

Number of visitors in June = 450,566

Number of visitors in July = 405,987

Arranging the number of visitors from greatest to least(In descending order).

450,566 > 450,082 > 405,987

450, 566 ; 450,082 ; 405,987
