This right triangle with 30°, 60° and 90° is called semi equilateral. Its particularity is that the side opposite to 30° is equal half of the hypotenuse.

Here the longest leg is nothing but the hypotenuse =18.(given):
Let  x be the side opposite to 60° and let's calculate it by Pytaghoras:

18² =(18/2)² + x²,

324 = 81 + x² . Subtract 81 from both sides

324 - 81 = 81 + x² - 81

243 = x² and x = √243 =9√3

A cone that is sliced through the vertex would make the shape of a triangle.

You are told the h eight is 10 cm and the radius is 4 cm.

The radius would be half the base, so the base would be 4 * 2 =8 cm.

The area of the triangle is found by multiplying the base by the height, then dividing by two.

Area = 8 x 10 = 80

80 / 2 = 40 square centimeters.

anzhelika [568]

Answer:

N*B*x/100

Step-by-step explanation:

To determine an equation of the total number of dollars, it is necessary to review the variables that influence

The most important, N that would be the number of shares of A.

The other variable is B, since it would be the price of the shares that were purchased.

Lastly, we have x, since he originally had was A's shares, therefore his increase occurred in A's shares, that is, x.

Therefore, the equation would be:

N * B * x / 100

It is divided by 100 since x is a percentage.

a fair (6 sided) die is rolled TWO times. What is the probability that the first die is a 2 or the second die is a prime
alexdok [17]

Answer:

The probability that the first die is a 2 or the second die is a prime = 1/12

Step-by-step explanation:

It is given that,a fair (6 sided) die is rolled TWO times.

The sample space for rolling 2 dies

(1, 1), (1, 2) .......... (1,6)

(2,1) ..........................

.

.

(6, 1) ..........................(6, 6)

There are total of 6^2  = 36 sample space

<u>To find the probability</u>

The prime numbers from 1 to 6 are 2, 3 and 5

the  possible outcomes are(2,1), (2, 3) and (2, 5)

The probability that the first die is a 2 or the second die is a prime = 3/36 = 1/12
