Approx. 53 rings will the tree have when its diameter is 20 inches.

<h3>What is the formula of unitary method?</h3>

The unitary method is used to find the value of a single unit from a given multiple.

For example: 50 boxes are of 500 rupees so what will be the price of 1 box.

50 boxes → Rs. 500

1 box → 500/50

1 box → Rs. 10

This method is mostly used for ratio and proportion concept.

Here, We have given that a maple tree with a diameter of 12 inches has 32 rings.

Total numbers of rings when its diameter is 20 inches.

so, using unitary method:

12 inches → 32 rings

1 inch → 32/12

20 inches → (32 x 20) / 12

20 inches → 53.3333 rings

taking the nearest possible whole number

20 inches → 53 rings

Hence, Approx. 53 rings will the tree have when its diameter is 20 inches.

How do you find probability in math?

damaskus [11]

Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail).

Find the exact value

Mnenie [13.5K]

By using properties for <em>trigonometric</em> functions and <em>trigonometric</em> expressions, we find that the <em>exact</em> value of the sine of the angle 5π/12 radians is $\frac{\sqrt{2+\sqrt{3}}}{2}$ .

<h3>How to find the exact value of a trigonometric expression</h3>

<em>Trigonometric</em> functions are <em>trascendent</em> functions, these are, that cannot be described algebraically. Herein we must utilize <em>trigonometric</em> formulae to calculate the <em>exact</em> value of a <em>trigonometric</em> function:

$\sin \frac{5\pi}{12} = \sqrt{\frac{1 - \cos \frac{5\pi}{6} }{2} }$
