Find the area of an equilateral triangle with a radius 6 square root of 3. Leave your answer in simplest radical form
Final answer:
The area of the equilateral triangle with a radius of 6√3 is 27√3 square units.
Explanation:
An equilateral triangle has all three sides equal in length and all three angles equal to 60 degrees. In this case, the radius of the circumscribed circle is given as 6√3. This radius is equal to the length of the side of the equilateral triangle.
To find the area of an equilateral triangle, we can use the formula A = (sqrt(3)/4) * s^2, where s is the length of the side of the triangle.
Substituting the given value of the radius into the formula, we have:
A = (sqrt(3)/4) * (6√3)^2 = (sqrt(3)/4) * 108 = 27sqrt(3).
Therefore, the area of the equilateral triangle is 27sqrt(3) square units.

How many square feet of outdoor carpet will need for this hole
Answer:
[tex]Area=63 square foot[/tex]
Step-by-step explanation:
The dimensions of the outdoor carpet which is rectangle in shape are:
L=6 ft and w=12 ft.
The dimensions of the indoor carpet that is triangle in shape are:
b=3 ft and h=9 ft.
Now, area of the outdoor= Area of the green region-Area of triangular region
[tex]Area=l{\times}b-\frac{1}{2}{\times}b{\times}h[/tex]
[tex]Area=6(12)-\frac{1}{2}{\times}3{\times}6[/tex]
[tex]Area=72-9[/tex]
[tex]Area=63 square foot[/tex]
Thus, the area of the outdoor carpet is 63 square foot.

Geoffrey wrote the following paragraph proof showing that rectangles are parallelograms with congruent diagonals.
According to the given information, quadrilateral RECT is a rectangle.
By the definition of a rectangle, all four angles measure 90°.
Segment ER is parallel to segment CT and segment EC is parallel to segment RT by the Converse of the Same-Side Interior Angles Theorem.
Quadrilateral RECT is then a parallelogram by definition of a parallelogram.
Now, construct diagonals ET and CR. Because RECT is a parallelogram, opposite sides are congruent.
Therefore, one can say that segment ER is congruent to segment CT.
Segment TR is congruent to itself by the Reflexive Property of Equality.
The _______________ says triangle ERT is congruent to triangle CTR.
And because corresponding parts of congruent triangles are congruent (CPCTC), diagonals ET and CR are congruent.

A piece of cloth is folded into a square with a side length measuring x inches. When it is unfolded, it has an area of x2 + 27x + 162 square inches.
Which could be the dimensions of the rectangular piece of cloth when it is unfolded? Remember, the area of a rectangle can be determined using the formula A = lw.
we need to factor the expression
[tex] x^{2} + 27x + 162 [/tex]
Equate to zero the expression
[tex] x^{2} + 27x + 162=0 [/tex]
Group terms that contain the same variable, and move the constant to the opposite side of the equation
[tex] x^{2} + 27x =-162 [/tex]
Complete the square. Remember to balance the equation by adding the same constants to each side
[tex] x^{2} + 27x +182.25=-162+182.25 [/tex]
[tex] x^{2} + 27x +182.25=20.25 [/tex]
Rewrite as perfect squares
[tex] (x+13.5)^{2}=20.25 [/tex]
[tex] (x+13.5)=(+/-)4.5 [/tex]
[tex] x1=-13.5+4.5= -9 [/tex]
[tex] x2=-13.5-4.5= -18 [/tex]
Hence
[tex] x^{2} + 27x + 162 =(x+9)*(x+18) [/tex]
Remember that the area of the rectangle is equal to
[tex] A=L*W [/tex]
therefore
the answer is
the dimensions of the rectangular piece of cloth could be
[tex] L=(x+18)\ inches\\ W=(x+9)\ inches [/tex]

A certain small factory employs 98 workers of these 10 recieve a wage of 150 dollars per day and the rest recieve 85.50 dollars a day to the management a week is equal to 6 working days how much does the factory pay out for each week
Answer:
The factor payout for each week is $54144. Below is the explanation
Step-by-step explanation:
Given:
There are 98 employs
10 of them receive $150 per day
88 of them receive $85.50 per day.
There are 6 working days in a week.
To find:
Let's find the wage per week by multiplying the wage per day by the number of people and the number of days in a week.
10 of them receive $150 per day.
So, they will receive $150*10*6
Which is simplified as $9000.
88 of them receive $85.50 per day
So, they will receive $85.50*88*6
Which is simplified to $45144.
So, the sum of wages for both would be $9000+$45144.
Add them together, which gives $54144.

What is an equation for the line with slope 2/3 and y-intercept 9?
Answer:
[tex]y=\frac{2}{3}x+9[/tex]
Step-by-step explanation:
We can describe a line using the following equation :
[tex]y=ax+b[/tex]
Where ''a'' and ''b'' are real numbers.
In the equation, the number ''a'' is the slope of the line. If we want a line with slope [tex]\frac{2}{3}[/tex] ⇒
[tex]y=\frac{2}{3}x+b[/tex]
The intersection of a line with the y-axis can be calculated replacing [tex]x=0[/tex] in the equation ⇒
[tex]y=(\frac{2}{3}).(0)+b\\y=b[/tex]
The interception is the real number ''b''. We want that interception to be 9
⇒
[tex]y=\frac{2}{3}x+9[/tex] is the equation of the line with slope [tex]\frac{2}{3}[/tex] and that intersects the y-axis at the point [tex](0,9)[/tex]

A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to return to the ground?
A) 1.75 seconds
B) 2.50 seconds
C) 2.75 seconds
D) 3.50 seconds
Answer:
D) 3.50 seconds
Step-by-step explanation:
You are interested in the positive value of t such that h=0. Substituting 0 for h, we get ...
0 = -16t^2 +56t
0 = -16t(t -3.5) . . . . . factored form
The product is zero when the factors are zero. Here, the factor of interest is ...
0 = t-3.5
3.5 = t . . . . . add 3.5 to both sides
The ball takes 3.5 seconds to return to the ground.
Final answer:
The ball takes D. 3.5 seconds to return to the ground.
Explanation:
To find the time it takes for the ball to return to the ground, we need to set the height function h equal to 0 and solve for t.
So, we have the equation -16t^2 + 56t = 0.
Factoring out t, we get t(-16t + 56) = 0.
Setting each factor equal to 0, we find that t = 0 or t = 3.5.
Since time cannot be negative, we disregard the t = 0 solution.
Therefore, the ball takes 3.5 seconds to return to the ground.
