A rectangular living room has a perimeter of 40 meters. Its area is 100 square meters. What are the dimensions of the living room?
In response to the question, we may say that So the dimensions of the rectangular living room are 10 meters by 10 meters.
What is rectangle?In Euclidean geometry, a rectangle is a parallelogram with four small angles. It may also be defined as a fundamental rule hexagon or one in which all of the angles are equal. Another alternative for the parallelogram is a straight angle. Four of the vertices of a square are the same length. A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.
Let's denote the length of the rectangular living room as "L" and the width as "W".
Perimeter = 2L + 2W = 40
L + W = 20
We also know that the area of the living room is 100 square meters.
Area = L x W = 100
L + W = 20 (equation 1)
L x W = 100 (equation 2)
We can solve for one of the variables in terms of the other in equation 1:
[tex]L = 20 - W\\(20 - W) x W = 100\\20W - W^2 = 100\\W^2 - 20W + 100 = 0\\where a = 1, b = -20, and c = 100.\\W = (-(-20) + \sqrt((-20)^2 - 4 x 1 x 100)) / 2 x 1\\W = (20 + \sqrt(400 - 400)) / 2\\W = 10\\L + 10 = 20\\L = 10\\[/tex]
So the dimensions of the rectangular living room are 10 meters by 10 meters.

Step-by-step explanation:
what two numbers multiply to equal -50 but adds up to equal 5
Answer:
10 and -5
Step-by-step explanation:
x + y = 5
xy = -50
y = 5 - x
x(5-x) = -50
5x - x^2 = -50
x^2 - 5x - 50 = 0
from there on we can solve the classic way
[tex]\Delta = (-5)^2 - 4\cdot1\cdot(-50) = 25 + 200 = 225\\\sqrt{\Delta} = 15\\x_1 = \frac{5 - 15}{2} = -5\\x_2 = \frac{5+15}{2} = 10\\y_1 = 5 - x_1 = 10\\y_2 = 5 - x_2 = -5[/tex]
Everything checks out.

There are 250 tables total in a cafeteria. There are 150 tables with red tablecloths and 100 tables with white tablecloths. As people walk into the cafeteria they are randomly assigned to a table. What is the probability of the first person through the door of being sat at a table with a red tablecloth? SIMPLIFY
Answer:
60%
Step-by-step explanation:
If there are 250 tables you can multiply it by 4 to work with 1000. This means you have to multiply the other table cloth numbers. 150 x 4 = 600. 100 x 4 = 400. Once you simplify you can get 40 white and 60 red out of 100. 60/100 = 60%.

Tom has arrive at the time of 259 248s.Find the number of Tom in Day,hour,Minute,Second
Answer:
3 days 0 hours 0 minutes 48 seconds
Step-by-step explanation:
Seconds = 259248 s
Number of days = Seconds given / 86400
Where 86400 = seconds in a day
The result is: 3 days remaining 48 seconds
Hours = Seconds Left / 3600 seconds.
Since the seconds left is 48, the hour = 0
Minutes = Seconds Left / 60 seconds.
Since the seconds left is 48, the minute = 0
Result:
3 days 0 hours 0 minutes 48 seconds

Answer:
Step-by-step explanation:
4). By applying cosine rule for angle R,
cos(∠R) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(33°) = [tex]\frac{x}{19}[/tex] [Equation]
x = 19cos(33°)
= 8.39
5). By applying sine rule,
cos(20°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
cos(20°) = [tex]\frac{15}{x}[/tex] [Equation]
x = [tex]\frac{15}{\text{cos}20}[/tex]
x = 15.96
6). By applying tangent rule,
tan(40°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(40°) = [tex]\frac{15}{x}[/tex] [Equation]
x = [tex]\frac{15}{\text{tan}40}[/tex]
x = 17.88
