Find the area of an equilateral triangle with radius 3 root 3.leave in simpliest radical form
Answer:
Area = 27√3/4 square units
Step-by-step explanation:
Since the shape is an equilateral triangle, all the sides will be equal
Area of the triangle = 1/2 * base * height
Get the height
(3√3)² = h²+(3√3/2)²
27 = h² + (27/4)
h²= 27 - 27/4
h² = 27 - 6.75
h² = 20.25
h = √2025/100
h = 45/10
Area = 1/2 * 3√3 * 45/10
Area = 135√3/20
Area = 27√3/4 square units

Answer:
History
Dubai’s golden era began in 1966. Oil was found at the offshore Fateh field, which is also known as the Fath of Oil. At that time, even the brightest brains could not begin to imagine Dubai relishing in the opportunities that are present in Dubai today. Oil became the gateway to a brand new world. Although it wasn’t a gateway for the locals to connect outside of Dubai, it was a gateway for foreigners to come into Dubai.
Merely a half a century ago, all of these big edifices, businesses, and residential developments were not even thought to exist. It may be hard to believe, but the village was indeed replaced by a thriving city. In 1883, Dubai’s current leaders took control, and ruled the village. Back then, the most critical financial source was limited to pearl-fishing.
Step by step, the whole city was replenished by new buildings, modern edifices and high-end apartments. The number of residents and which is of more importance, tourists is still increasing, and thus the hotels, townhouses, penthouses and apartments for rent are of high demand. Today, when you look at the exceptional oasis created by Sheik Mohammed bin al-Maktoum, along with the crown prince, it is hard to believe that this was once a village with a limited source of finances.

water tank is being filled with water. Before water is pumped in, the water level in the tank is 12 inches high. After 20 minutes, the water level is 54 inches high.
If t represents the time in minutes and h represents the water level, which of the following equations can be used to model this situation?
A. H = 42 + 12t
B. H = 2.1t - 12
C. H = 12t + 2.1
D. H = 2.1t + 12
Answer:
D. H = 2.1t + 12
Step-by-step explanation:
Let us assume the t be the time in minutes
And h be the water level
Now before reaching to the equation that need to be used
before this, determine the inches per minute i.e.
= 54 inches - 12 inches
= 42 inches in 20 minutes.
Now for per minute, it would be
= 42 inches ÷ 20 minutes
= 2.1 inches per minute
After this, multiply the inches per minute with the minutes t and add the sale to the beginning value i.e. 12
So the equation is
H = 2.1t + 12
hence, the last option is correct

Which expression is equivalent to (x+2)(3x-3)?
A.3x^2 - 6
B.3x^2 + 6x - 6
C.3x^2 + 9x - 6
D.3x^2 + 3x - 6
Answer:D

Question 4 options:
A)
77°.
B)
103°.
C)
167°.
D)
13°.
Answer:

How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
Noted that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
