(x+5)*3/4-2=7    (x+5)*3/4=9   x+5=12   x=7 What a surprise! It's 7.

Multiply the number by 0.1 and you will get 10% of that number.

It is possible in more ways. 4.4 is equal to 44/10 which is equal to 22/5. Or, you can write it as 4 and 2/5.

Four tenths is 0.4 and three tenths is 0.3.

One molecule of methane contains 1 carbon and 4 hydrogen atoms.

Actually, gravity is everywhere. But, this gravitational force depends on the product of the masses of the objects, which attract each other, and on the distance between them. The smaller the mass, the lower the attractive force. The larger the distance between the objects, the lower the attractive force (gravitational force decrease with the inverse … Read more

Both radio waves and light are kinds of electromagnetic waves. The difference is in their wavelength. Radio waves have the wavelength in the range, let us say, kilometers (even to 100000 km) to millimeters (microwaves). Light refers typically to the spectral region of about 380-750 nm, visible light only approximately 400-700 nm.

The main aim of nanotechnology is to advance the life quality of human beings.
