1. the sum of two rational numbers is always always a (irrational number / rational number)

Blizzard [7]

One

The sum of two rational numbers is always rational. sqrt(9) + sqrt(25) = 3 + 5 which is rational. sqrt(16/100) = 4/10 = 2/5 is also rational. 3/28 is rational as well.

Two

Those are irrational. sqrt(10) + pi = ???? You cannot reduce this to any kind of fraction. Two irrationals always give a rational.

Three

The irrational number controls the answer. 10 + sqrt(5) is irrational. The 10 is OK. It is raional, but sqrt(5) is not a rational number.

Calculate the density of the object using the information in the picture. Question 5 options: 0.052 ml/g 19.2 g/ml 19.2 ml/g 139

olga_2 [115]

The density of an object is obtained by taking the ratio of the mass of the object and its volume ; $Density = \frac{Mass}{Volume}$

There is no picture attached and no picture corresponding to the question could be found.

However, the required formular for calculating the density of an object is :

$Density = \frac{Mass}{Volume}$

The mass of the object is measured in gram(g) or kilogram(kg)

The volume of the object measured in Litre or any equivalent unit.

Therefore, the density of the object is the ratio of its mass and volume.
