Answer:

x=47

y=23

Step-by-step explanation:

x+y=70

y=-x+70

x-y=24

x-(-x+70)=24

x+x-70=24

2x=94

x=47

y=-(47)+70

y=23

a rectangular parking lot has an area of 7/10 square kilometer the width is 1/3 kilometer what is the length of the parking lot
Virty [35]

Answer:

2\frac{1}{10} km

Step-by-step explanation:

We are given;

  • The are of a rectangle as 7/10 km²
  • Width of the rectangle is 1/3 km

We are required to find the length of the rectangle;

We need to know how to find the area of a rectangle first;

Area of rectangle = Length × Width

Rearranging the formula;

Length = Area of rectangle ÷ Width

            = 7/10 km² ÷ 1/3 km

   We get;

           =\frac{7}{10} *\frac{3}{1}

           =\frac{21}{10}

           =2\frac{1}{10} km (improper fraction)

Thus, the length of the rectangular park is 2\frac{1}{10} km

Dilation is the process of making something scaled. In the rectangle with a length of 4 and a width of 2, there is no dilation.

<h3>What is the rectangle?</h3>

A rectangle is a quadrilateral whose opposite sides are parallel and are of equal measurement.

<h3>What is dilation?</h3>

Dilation is the process of making something bigger or wider or scaled.

As we have the length of the rectangle as 4 and the width of the rectangle as 2, which is the same as before as well. therefore, there is no change in the length or the breadth of the rectangle. Thus, we can say that there is no dilation in the length and breadth of the rectangle.

Hence, In the rectangle with a length of 4 and a width of 2, there is no dilation.

Assume that the radius of the circle is 1.


The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).


Finally, the ratio of the square to the circle, in area, will be


(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi


We can conclude that the white area is about 35%.
