Even Irrational numbers are real numbers. So the question is false.
2x - 4y = -2
2x + 3y = -16
What is the solution
Answer:
x=-5
y=-2
Step-by-step explanation:
equation 1 - equation 2
(2x-4y=-2) - (2x+3y=-16) = (-7y=14)
y=14/-7=-2
then substitute y=-2 into any equation
2x-4(-2)=-2
2x+8=-2
2x=-10
x=-10/2=-5

Please help I need to find the measure of the three unknown variables. Any help will be greatly appreciated:))
Answer:
[tex]x = 8 \sqrt{3} [/tex]
[tex]y = 60[/tex]
[tex]z = 30[/tex]
Step-by-step explanation:
To find x, use pythagorean theorem,
[tex] {x}^{2} + {8}^{2} = {16}^{2} [/tex]
[tex] {x}^{2} + 64 = 256[/tex]
[tex] {x}^{2} = 192[/tex]
x=13.9 or 8 times sqr root 3( see later)
To find y, use cosine ratio.
[tex] \cos(y) = \frac{8}{16} [/tex]
[tex] \cos(y) = \frac{1}{2} [/tex]
[tex]y = 60[/tex]
To find z, use triangle interior theorem
[tex]90 + 60 + z= 180[/tex]
[tex]150 + z = 180[/tex]
[tex]z = 30[/tex]
Since this a 30-60-90 triangle, side x could be also written as
[tex]8 \sqrt{3} [/tex]

Actually Welcome to the concept of Areas,
Let's divide the above map in to 2 parts , that is a rectangle and a triangle, and add both thier areas to get the area of the Nevada.
so we get as,
Area of triangle = 1/2*b*h
Area of triangle ==> 1/2*309*306 ==> 47277 mi^2
Area of rectangle = l*b = 205*309 ==> 63345 mi^2
Area of NEVADA = 47277 + 63345 = 110622 mi^2
hence the area = 110622 mi^2
Answer:
the approximate area of Nevada is 110,567 mi²

the same. If the tennis court is 78 feet long and 36 feet wide, what is the area of the entire surface inside the fence?
Answer:
the answer is 2,808
Step-by-step explanation:
you have to multiply 78 by 36 because it is area

Answer and Step-by-step explanation:
The numbers that are irrational are the square root of 27 and the square root of 55. ( [tex]\sqrt{27}, \sqrt{55}[/tex] ).
This is because those numbers don't have a perfect square root.
The square root of 16 and the square root of 64 have perfect square roots (16 having the answer as 4, and 64 having the answer as 8).

HELP PLEASE!!! I really dont understand this!
i need help please this is quite hard for me
Some one help me solve for x
Answer:
x = 10
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
9x + 15 + 85 + 90 + 80 = 360, that is
9x + 270 = 360 ( subtract 270 from both sides )
9x = 90 ( divide both sides by 9 )
x = 10
The coldest place where humans live is the Siberian village of Oymyakon. On February 1993 the temperature fell to -67.7 degrees c.This is the lowest temperature recorded outside Antarctica!Investigate the temperature in different places around the world.List the temperatures in order,starting with the coldest.
The coldest temperature ever recorded on earth is -89.2 degrees Celsius (-128.5 degrees Fahrenheit) at Vostok, Antarctica on July 21, 1983. That all-time low broke the previous world-record minimum of -88.3 °C (-126.9 °F), set on August 24, 1960, also at Vostok.
Vostok is a Russian research station located high in the middle of the East Antarctic ice sheet, about 1,300 kilometres from the geographic South Pole.
This is a place where the sun doesn't rise during winter. Besides being extremely far south, the station's high elevation, at 3,420 metres (11,220 feet), helps it get really cold.
The conditions that caused the temperature to drop exceptionally low at Vostok in July 1983 were clear skies accompanied by calm air. Vertical mixing of the air was minimal and no wind had stirred for some time.
Vostok is not an outlier in the Antarctic temperature regime. On July 20th, 1968, the temperature at another high elevation research base, called Plateau Station, sank to -86.2 °C (-123.1 °F).
