Answer:
C. 36√3 square units
Step-by-step explanation:
Your knowledge of special triangles tells you that height CD is ...
CD = 6√3
so the area is ...
A = 1/2bh
A = 1/2(12)(6√3) = 36√3 . . . . square units
_____
Additional comment
The 30°-60°-90° right triangle that is half an equilateral triangle has a short side equal to half the length of the long side. The Pythagorean theorem tells you that the middle-length side is √(2²-1²) = √3 times the shortest side. That is, the side length ratios in this "special" triangle are ...
1 : √3 : 2
This means the length DB is 12/2 = 6, and the length CD is 6√3.

Answer:
about 703.69
Step-by-step explanation:
To calculate the base you would use pi radius squared: 153.93
Since you have 2 bases you would multiply that by 2: 307.87
Then you need to find the circumference (2 pi radius) : 43.98
Then you multiply the circumference by the height: 395.82
Add the bases and the sides to get 703.69

Each week a discount of 15% of the previous week.So the price will be 85% of the previous week (17/20 of the previous price)
We multiply the price from the previous week by 0.85 to obtain the new price
200 x 0.85 = 170
170 x0.85 = 144.50.....and so on
3)$ 122.82

Each week the saving will be 85% of the previous week. But the shoes will not be free in 2 months On the week 8 the price will be $54.50
what are the two solutions to x( 2x - 5) = 0
Answers
Therefore you know that:
x = 0 and 2x - 5 = 0
2x - 5 = 0, solve for x
2x = 5, x = 5/2
Solution: x = 5/2, x = 0
A circular plate has circumference 33.3 inches. What is the area of this plate? Use 3.14 for Pi.
The area of this plate is_____about square inches.
(Round the final answer to the nearest whole number as needed. Round all intermediate values to the nearest
thousandth as needed.)
Answers
Answer:
88 square inches
Step-by-step explanation:
A circular plate has circumference 33.3 inches.
Step 1
We find the radius
The formula to find the radius go a circle given circumference is
= C /2π
r = 33.3/2 × 3.14
r = 5.3025477707 inches
Approximately to the nearest thousandth = 5.303 inches
Step 2
What is the area of this plate? Use 3.14 for Pi.
The area of a circle = πr²
Where
π = 3.14
r = 5.3025477707 inches
Hence
Area of the circle = 3.14 × (5.303inches)²
= 88.30248026 square inches
Approximately to the nearest whole number the area of the circle = 88 square inches
The area of this plate is about 88 square inches.

Step 1: (5×k= 5k) (5×4=20) equation is now 5k+20-2k

78 cm^2
Step-by-step explanation:
This will require 3 steps.
1) Area of the entire rectangle
18cm * 8 cm = 144 cm^2
2) Area of the square with one side length of 9cm
The missing measurement for the heights below 2cm
8cm - 2 cm = 6 cm
This area will be 6cm * 9 cm = 54 cm^2
3) Triangle
You have your height, which is 6cm
You also have your base, 18 cm total length minus the 5 cm stated minus the 9 cm also stated.
18cm - 5cm - 9 cm = 4 cm
The area of a triangle is A= h b/2
A = 6 * (4/2)
A = 12 cm^2
Now substract the sum of the smaller rectangle and the triangle from your large triangle

the circumference is 12 mile. What is the diameter?
Answers
To find the diameter of a circle, using only the circumference, you need to divide the circumference by π, or 3.14.
So in this case, you must divide 12 by 3.14, which gives you 3.82.
I even double checked this, and should be correct then.
Answer:
The diameter is approximately 3.8 mi
Step-by-step explanation:
The circumference formula is C = πd. Dividing both sides by π results in a formula for d (diameter) when C is known:
d = C / π
In this case, with C = 12 mi,
d = 12 mi / π, or approximately 3.8 mi
In circle L with m^KLM 54 and KL= 10 units, find the length of arc KM.
Round to the nearest hundredth.
Answers
Given:
In circle L, measure of angle KLM is 54 degrees and KL = 10 units.
To find:
The length of arc KM.
Solution:
The formula for arc length is:
[tex]s=2\pi r\times \dfrac{\theta}{360^\circ}[/tex] ...(i)
Where, r is the radius of the circle and [tex]\theta [/tex] is the central angle in degrees.
The measure of KL is 10 units, it means the radius of the circle L is 10 units.
The measure of angle KLM is 54 degrees, it means the measure of central angle on arc KM is 54 degrees.
Putting [tex]\pi=3.14, r=10,\theta=54^\circ[/tex] in (i), we get
[tex]s=2(3.14)(10)\times \dfrac{54^\circ}{360^\circ}[/tex]
[tex]s=20(3.14)\times 0.15[/tex]
[tex]s=9.42[/tex]
Therefore, the length of arc KM is 9.42 units.
