all three sides are the same length, there is a simpler formula:
Area<span>=</span><span>√</span><span>3/4 </span><span> </span><span>s</span><span>2
s = side </span>
The height of the chimney above the floor of the observation deck is 52.4 ft
Two right angle triangle will be formed.
<h3>Right angle triangle:</h3>
Right angle triangle are triangle that has one of its angle as 90 degrees.
Therefore, using trigonometric ratio,
adjacent side = distance of observer from the bottom edge of the Delaware River drawbridge observation deck
Therefore,
tan 40 = opposite / adjacent
Where
x = height of the observer to the top of the observation deck
tan 40 = x / 200
x = 200 tan 40
x = 167.819926235
x = 167.82 ft
tan 30 = opposite / adjacent
y = height of the observer to the bottom of the observation deck
tan 30 = y / 200
y = 200 tan 30
y = 115.470053838
y = 115.47 ft
The height of the chimney above the floor of the observation deck = height of the observer to the top of the observation deck - height of the observer to the bottom of the observation deck
The height of the chimney above the floor of the observation deck = 167.82 - 115.47 = 52.35 ft

Final answer
The formula for simple interest is Interest= Principle·Rate·Time
If one of these is missing, just plug in what you know. For example, if time if the principle is missing just plug in the rest. Say the interest is $264, the rate is 6% and the time is 2 years. When its plugged it, it looks like this: 264= P ·0.06·2 Now you can work it out 0.06·2 is 0.12 so 264=P 0.12. Just divide by 0.12 and your done! You can do this with any letter and just put in the info you know. I hope that this helps you! :)
Answer:
The probability that the next person will purchase no more than one costume .
Step-by-step explanation:
The data for a single day is s follows:
- 236 visitors purchased no costume.
- 202 visitors purchased exactly one costume.
- 40 visitors purchased more than one costume.
The total number of customers is, <em>N</em> = 236 + 202 + 40 = 478.
Let <em>X</em> denote the number of costumes purchased by the next person.
Compute the probability that the next person will purchase no more than one costume as follows:
Thus, the probability that the next person will purchase no more than one costume .
