Answer:

-1/2

Step-by-step explanation:

The ratio is found by dividing the second number by the first:

-52/104 = -1/2

You can verify that this is a "common" ratio by doing the same with successive pairs of numbers:

26/-52 = -1/2

-13/26 = -1/2

The common ratio is -1/2.

Which equations support the fact that rational numbers are closed under subtraction? Select each correct answer

noname [10]

The rationals being closed under subtraction means that if we start with two rational numbers and subtract them, we get another rational number. Choice c subtracts two rational numbers but gets the wrong answer, so isn't support for anything. Choice b is rational too because the square root of 4 is 2.

Answer: b

Answer:

844368.7 m

Step-by-step explanation:

We are given that a typical sugar cube has an edge length of 1.00 cm.

We have to find the edge length of the box in meters.

Edge length of sugar cube=1 cm = $10^{-2}m$ ( $1 cm=\frac{1}{100}m$ )
