the sides of the triangles. show your work below the numbers.
7. 1/2 /3 /5

8. 0.1 0.15 0.2

7.

8.

Step-by-step explanation:

Given:

Three sides of the triangles are given.

For Question 7

1/2 _ 1/3 _1/5

For Question 8

0.1 _ 0.15 _ 0.2

We need to use >, <, and + signs to write inequalities for the relationships among  the sides of the triangles.

Solution:

Part 7.

Property of the triangles.

Sum of two side of triangles must be greater than third side.

So, first, second and third side of the triangle is

So, its satisfy the triangle rule.

Therefore, Inequality is

Part 8.

Property of the triangles.

Sum of two side of triangles must be greater than third side.

So, first, second and third side of the triangle is

So, its satisfy the triangle rule.

Therefore, Inequality is

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
