The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.

X=y+4
x+y=20

now substitute the x for (y+4) in the second equation
(y+4)+y=20
2y+4=20
2y=16
y=8
now substitute 8 for y in the first equation
x=8+4
x=12
so y=8 and x=12

A large cube has a volume of 1 cubic unit. A small cube has a volume of 1 27 of a cubic unit. What is the difference between the

ExtremeBDS [4]

Given:

Volume of Large cube = 1 cubic unit

Volume of small cube = $\dfrac{1}{27}$ cubic unit

To find:

The difference between the edge length of the large cube and the edge length of the small cube.

Solution:

Let the edges of large and small cubes are $a_1$ and $a_2$ respectively.

We know that, volume of a cube is

$V=(edge)^3$

Volume of Large cube = 1 cubic unit

$(a_1)^3=1$

Taking cube root on both sides, we get

$a_1=1$

So, edge of large cube is 1 unit.

Volume of small cube = $\dfrac{1}{27}$ cubic unit

$(a_2)^3=\dfrac{1}{27}$

Taking cube root on both sides, we get

$a_2=\dfrac{1}{3}$

So, edge of large cube is $\dfrac{1}{3}$ unit.

Now, difference between them is

$d=a_1-a-2$

$d=1-\dfrac{1}{3}$

$d=\dfrac{3-1}{3}$

$d=\dfrac{2}{3}$

Therefore, the difference between the edge length of the large cube and the edge length of the small cube is $\dfrac{2}{3}$ unit.

A vertical plane passes through a pyramid that has a horizontal base. which of the following can be produced from the intersecti

Inessa [10]

Answer with explanation:

Pyramid and Plane both are three dimensional shapes.

Pyramid is a three dimensional shape having base any polygon and other faces as triangles.

The base of pyramid is horizontal.

1. If lower base is a Square,or rectangle or any other parallelogram

And, then , plane cuts the pyramid vertically

It will be also, a three dimensional shape ,resembling a triangular cross section in three dimension.

Triangle is appropriate choice.
