Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
Suppose the base of right triangle sail is b
Suppose the height of right triangle sail is h
It is given that, it is three times higher as it is wide.

Area of right triangle is A = 

Plugging the value of h in terms of b



Hence height h = 
Hecne the height of sail is 6 meters. : Answer
Hope it will help :)
Answer:
<em>Average rate of change is </em><em>-78.</em>
Step-by-step explanation:
A talent competition on television had five elimination rounds. After each elimination, only one-third of the contestants were sent to the next round.
The table that shows the number of contestants in each round of the competition is,
x f(x)
1 243
2 81
3 27
4 9
5 3
Average rate of change is the change in the y-value divided by the change in the x-value for two points on the graph.
i.e 
So, the average rate of change of
from
to
is,




Since f(x) is decreasing, so rate of change is negative.
14 hours.......200 divided by 15 is 13.3333333 so your answer is 14
hope i could help sorry if i get it wrong
Answer:
The expression can be given as : 
Step-by-step explanation:
Though any options are not given, but the question is complete so we can solve this by assuming the initial price of the property to be = x
Given, that the price is increased by 275%, this means x+x(275%)
275% can be written as : 
So, the expression can be given as : 
Answer:
x = 128 degrees
Step-by-step explanation:
First figure out the angle inside the triangle
1st step: add 55 and 73 together:
⇒ 55 + 73 = 128
2nd step: subtract the sum from 180:
⇒ 180 - 128 = 52
to find x, take 180 again and then subtract 52 from it:
⇒ 180 - 52 = 128
