What number produces a rational number when added to 1/3

Mathematics

Bingel [31]3 years ago

Answer:

1/2, 4/3, 1/2, ... any rational number

Step-by-step explanation:

The field of rational numbers is closed under the sum operation. Therefore, if a and b are rational numbers, the number (a + b) is also a rational number.

Consider the rational number a = 1/3, if we add it to any other rational number, the result of that sum will also be a rational number.

Examples:

1/3 + 1/2 = 5/6

1/3 + 4/3 = 5/6

1/3 + 1/6 = 1/2

Answer:

Any rational number

Step-by-step explanation:

A <em>rational number</em> is a number obtained by dividing two integers.

Thus, 1/3 is a rational number.

You can add <em>any rational number</em> to 1/3 and the sum will be a rational number.

Point X has coordinates (-4, -5) and point y has coordinates (--1, --5 ) which expression models the distance between points X a
sdas [7]

Answer:  The last expression shows the result of 3  so it models the distance between x and y.

Step-by-step explanation:

First you will have to  find the distance between the two points by square the x coordinates and squaring the y coordinates to find their sum .  

-4 - (-1) = -3

-5 - ( -5) = 0

-3^2 + 0^2 = d^2   where d  is the distance

9  = d^2

d= 3  

The distance is 3 units  

Now evaluate which expression have a solution as 3.

The last expression is the answer

the absolute value for -4 is 4   , and the absolute value for -1 is 1  and 4 minus 1 is 3.

A small box in the shape of a cube for packaging has a volume of 64 cubic inches.
Oduvanchick [21]
  1. The volume of a medium box is 512 cubic inches.
  2. The ratio of the sides of the small box to the medium box is 1:2.
  3. The ratio of the area of the small box to the medium box is 1:4.
  4. The ratio of the volume of the small box to the medium box is 1:8.

<h3>What are the ratio of the small box to the medium box?</h3>

The first step is to determine the side lengths of the small box.

Side length = ∛64 = 4 in

Side lengths of the medium boxes = 4 x 2 = 8 inches

Volume of the medium box = 8³ = 256 cubic inches

The ratio of the sides of the small box to the medium box = 4 : 8 = 1:2.

The ratio of the area of the small box to the medium box= (4 x 4) : (8 x 8) =  1:4.

The ratio of the volume of the small box to the medium box = 4³ : 8³ = 1 : 8.
