The square of the 20 is 400. Therefore the amount required is 1/5 of the squared height because 80/400 is 1/5. So, the square of 25 is 625. 1/5 of 625 would be 125 pounds of gold that is required

A school is designing two rectangular parking lots. The second parking lot is being designed so that its perimeter is 3/4 of per
Nataly [62]

The perimeter of second plot is 180 feet

<em><u>Solution:</u></em>

Given that,

The second parking lot is being designed so that its perimeter is 3/4 of perimeter of the first parking lot

<h3><u>Find the perimeter of first plot:</u></h3>

Perimeter = 2(length + width)

From given figure in question,

length = 40 feet

width = 80 feet

Therefore,

Perimeter = 2(40 + 80)

Perimeter = 2(120) = 240

Thus, we got,

Perimeter of first parking plot = 240 feet

Also, given that,

\text{Perimeter of second plot }= \frac{3}{4} \times \text{Perimeter of first parking plot}\\\\\text{Perimeter of second plot }= \frac{3}{4} \times 240\\\\\text{Perimeter of second plot }= 180

Thus perimeter of second plot is 180 feet

A circular region has a population of about 260000 people and a population density of about 135 people per square mine . find th
ValentinkaMS [17]

Answer:

24.76 mine

Step-by-step explanation:

The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:

260000/135 = 1925.93

The area would be 1925.93 square mine

We know that the area is given by:

A = pi * r ^ 2

we solve to r

r ^ 2 = A / pi

r ^ 2 = 1925.92 / 3.14

r ^ 2 = 613.3

r = 24.76

the radius is equal to 24.76 mine
