Elan Coil [88]

Answer:

34.72 feets

Step-by-step explanation:

Using the relation :

Length of tree / shadow of tree = height of melody / shadow of melody

From the details given in the question :

Let height of tree = h

h / 62 = 5.6 / 10

Cross multiply

h * 10 = 62 * 5.6

h = 347.2 / 10

h = 34.72 feets

Hence, the height of tree is 34.72 feets

What is (6 + 6 + 6) · (6² + 1²)?<br><br> Please don't tell the answer is the devil number.
VikaD [51]
(6+6+6)(36+1) = (18)(37) = 666. ... If you don't want an answer posted, there's a simple solution ... don't post the question ! And if it still mysterously somehow appears, then for heaven's sake, don't offer points as a reward for an answer. ... Finally ... devil's numbers belong in the Old Wives' Hooey category, not in the Mathematics one. They're not real.

posledela

\huge \underline\text {Hello There!!}

<h3><u>Given</u></h3>

Rolled A six-sided dice.

<h3><u>To </u><u>Find </u></h3>

P(Prime) as percentage

<h3><u>Solution</u></h3>

Total Possible Outcomes= 1, 2, 3, 4, 5, 6.

So, No. of possible Outcomes= 6

Prime number of the dice= 2, 3, 5

So, No. of favorable outcomes of Prime number= 3

<h3><u>We Know,</u></h3>

\text{Probability of an event= }

\frac{ \text{favorable no. of outcome}}{ \text{total no. of outcome}}  \times 100

\text{Percentage of Probability getting P(Prime) number on face of dice} =

\frac{3}{6}  \times 100 \\   \\ =  \cancel \frac{3}{6}  \times 100 \\  \\  =  \frac{1}{ \cancel2}  \times  \cancel{100} \\  \\  = 50\%

\therefore \% \text{ Probability of getting prime number is  \red{50}   \red\%}

<h3>Hope This Helps</h3>
