The information that would prove that DEFG is an isosceles trapezoid is

DE ≅ GF.

An isosceles trapezoid is a trapezoid in which the base and it's opposite side are parallel and the length of the non-parallel sides are same.

Here, the given trapezoid:

the coordinates of the points D and G are (- 2, 2) and (1, 2) respectively.

the coordinates of the points E and F are (- 2, 2) and (1, 2) respectively.

Therefore, it is clear that the base of the given trapezoid EF and it's opposite side DG are parallel.

Therefore, the given trapezoid would be isosceles, if DE and GF are equal.

Answer:

Answer C.12

Step-by-step explanation:

v/V=(h/H)^3

1/8=(h/24)^3

1/8=h^3/24^3

1/8=h^3/13824

8h^3=13824

H=1728√3

h= \sqrt[3]{1728}

h=12 cm

the height of the smaller pyramid is 12 inches.

A triangular pyramid is a 3D geometric shape in which all the three lateral faces are triangles with a common vertex. If all the three triangular faces are equilateral, then such a pyramid is called a tetrahedron.

For the given situation,

The ratio of the volumes of two geometrically similar pyramids = 1:8

The height of the larger pyramid = 24 inches.

Let the volume of smaller pyramid be v1 and larger pyramid be v2.

Let the height of smaller pyramid be h1 and larger pyramid be h2.

The relation between the volume of pyramid and height is given as

[tex]v=\frac{1}{3} (base area)(height)[/tex]

Let us consider the triangle to be equilateral triangle. So all the sides are equal.

We know that, Base area = [tex]a^{2}[/tex] and [tex]a=h[/tex]

The volume becomes [tex]v=\frac{1}{3} h^{3}[/tex]

The ratio becomes,

⇒ [tex]\frac{v1}{v2} =\frac{h1^{3} }{h2^{3}}[/tex]

⇒ [tex]\frac{1}{8} =\frac{h1^{3} }{24^{3}}[/tex]

⇒ [tex]h1^{3}=\frac{24^{3} }{8}[/tex]

⇒ [tex]h1^{3}=\frac{13824 }{8}[/tex]

⇒ [tex]h1^{3}=1728[/tex]

⇒ [tex]h1=\sqrt[3]{1728}[/tex]

⇒ [tex]h1=12[/tex]

Hence we can conclude that the height of the smaller pyramid is           12 inches.

The speed of the fan is 1884 inches per second.

Step-by-step explanation:

Revolution per minute= 4000

Radius = 4.5 inches

Circumference= 2π r

= 2(3.14) (4.5)

= 28.26 inches

1 revolution= 28.26 inches

4000 revolution= (28.26) (4000)

=113040 inches per minute

= 113040/60

= 1884 inches per second

The speed of the fan is 1884 inches per second.

Final answer:

To find the angular speed of a fan blade given its revolution per minute, multiply the revolutions per minute by 2π to get the angular speed in radians per minute.

Explanation:

An electric powered fan has a 9-inch diameter blade rotating at 4000 revolutions per minute. To find the angular speed in radians per minute, we can use the formula: Angular speed (in rad/min) = (revolutions per minute) x 2π. Therefore, angular speed = 4000 x 2 x π = 8000π rad/min. So, the angular speed of the fan blade is 8000π radians per minute.

Answer:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.

Step-by-step explanation:

2x + 2y = 3 ( x2 for everything in the equation)

x - 4y = -1

4x+ 4y = 6

x - 4y = -1

Add the 1st line to the 2nd line to get rid of the y:

5x = 5

x - 4y = -1  ( you can pick any line from this system to be the second equation in this step, you can put 2x + 2y = 3 or 4x+ 4y = 6, anything above this step, but to make it simple chose the one you think is the easiest)

Solve for x, then plug the x value into the 2nd equation

x = 1

1 - 4y = -1

x = 1

-4y = -2 =) y = 1/2

x = 1

y= 1/2

the equation is addition so its 68

Answer:

m/60.

Step-by-step explanation:

There are 60 minutes in an hour so the expression is m/60 hours..

The algebraic expression for the number of hours in m minutes is m/60. This is because there are 60 minutes in an hour, so dividing the number of minutes by 60 gives the equivalent number of hours.

The task is to write an algebraic expression that represents the number of hours in m minutes. Since 1 hour is equal to 60 minutes, we can set up a conversion factor that allows us to go from minutes to hours. To find the number of hours in m minutes, we divide the number of minutes by 60 (the number of minutes in an hour). So, the algebraic expression for the number of hours in m minutes would be m/60.

To further simplify the context, think of a situation where you might need to convert 120 minutes to hours. Using the algebraic expression described, you would divide 120 by 60, which would result in 2. Therefore, 120 minutes is equal to 2 hours.

X=26

Step-by-step explanation:

since 2x and 3x are on the same side of the equation you can combine the to get 5x+50=180. Then you subtract 50 from both sides of the equation witch you would get 5x on one side of the equation and 130 on the other. The you would divide 5x from both sides. 5x and 5 cancel out so you are left with 130 divide by 5x. You the divide which gives you the answer of X=26.
