Divide the numbers in around the answer to the correct number of significant figures. 163.8/8.64=
Please HELP!!

Explanation:

In multiplication and division problems, the answer can have no more significant figures than the number with the fewest significant figures.

A calculator gives the result:

163.8    has four significant figures.

   8.64 has three significant figures.

You must round to three significant figures.

That is, you drop all the digits to the right of the 9 — the red line in Fig. 1 below. You are rounding to the nearest tenth.

To round a number to the nearest tenth, you look at the digit in the hundredths place (7). See Fig. 2.

If the digit to be dropped is greater than 5 or is 5 followed by at least one non-zero digit, you add 1 to the number in the tenths place (Fig. 3).

Here's how you do it.

The tenths digit becomes 0 and the ones digit increases from 8 to 9.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table
