√6 = 2.449489742783...........

Is a irrational number, because an irrational number is a number that con ONLY be written as a decimal, and not as a ratio/fraction and this number CAN'T be written as a ration/fraction.

On the other hand rational means that a number can be written as a ratio/fraction AND a decimal.

So, this is an irrational number.

Hope I helped ya!!!!!!!!!

It is an irrational number.

Irrational numbers can be written as a decimal but not a fraction. It has an endless non-repeating digits to the right of the decimal point.

Rational numbers are those that can be written as a ratio. Meaning it can be written as a fraction where both numerator and denominator are whole numbers.

A 10-ounce box of cereal cost $3. A 20-ounce box of the same cereal cost $5. A third box of the same cereal costs $8.

kvasek [131]

The number of ounces of cereal in the third box is 32.

Explanation:

Given-

10 oy box = $3

Price of 1 ounce box = $3/10

= $0.3

20 oy box = $5

Price of 1 oy box = $5/20

= $0.25

Therefore, it is beneficial to buy a 20 oy box as it is comparatively cheaper than the 10 oy box.

Third box of cereal = $8

$5 is the price of 20 oy box

$8 will be the price of x oy box

So,

$x = \frac{20}{5} X 8\\ \\x = 32$

Therefore, the number of ounces of cereal in the third box is 32.

Describe the faces, edges, verticals of each three dimensional figure. Then identify it.

EastWind [94]

When you have to describe a 3D shape you have to keep the following definitions in mind:

1. The face of a 3D shape is a flat surface.

The shape on the picture has 3 rectangular faces and 2 triangular faces, a total of 5 faces.

2. The edge is where two faces meet.

For the shape on the picture, there are 3 edges, where the rectangular faces meet each other, and then three edges where the rectangular faces meet each of the triangular faces, this shape has a total of 9 edges.

3. The vertex is a corner, where the edges meet.

There are three vertices on each end of the shape, so it has a total of 6 vertices.

A shape that has 5 faces, 9 edges, and 6 vertices is a triangular prism.
