dimulka [17.4K]

Answer:

15x^2+5xy-125=0

Step-by-step explanation:

We are give the following in the question:

Dimensions of rectangle:

Length , l =

l = x\sqrt{100} = 10x

Width of rectangle, w =

w = \dfrac{y}{2} +\dfrac{3x}{2}

Area of rectangle = 125 square cm.

Area of rectangle =

A =l\times w

Putting values, we get,

125 = 10x\times (\dfrac{y}{2}+\dfrac{3x}{2})\\\\125 = 5xy+15x^2\\15x^2+5xy-125=0

is the required equation.

Elizabeth has a swimming pool at home. She wants to build a deck all the way around her rectangular swimming pool. The width of
galben [10]

Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.

<h3>What is the perimeter of a rectangle?</h3>

The perimeter of a rectangle of length l and width w is given by:

P = 2(l + w)

In this problem:

  • She has enough wood to build a deck that is 280ft, hence P = 280.
  • The length is of 10 feet, hence l = 10.
  • Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.

Then:

P = 2(l + w)

280 = 2(10 + 8 + w)

36 + 2w = 280

2w = 244

w = \frac{144}{2}

w = 122

She can make a deck of 122 ft wide.

iVinArrow [24]

Step-by-step explanation:

You didn't give the box plot, but to obtain the percentage of people between 20 and 37 years old, first of all, find the total number of people, T. Next, find the total number of people between 20 and 37 years old, t.

Then the percentage we want to find is:

P = T/t × 100
