Find the area of a regular hexagon with a said length of 10 centimeters and a apothem of 5 spuare root 3
Answers
Answer:
C
Step-by-step explanation:
the area (A) of the hexagon can be calculated as
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
p = 6 × 10 = 60 and a = 5[tex]\sqrt{3}[/tex] , then
A = [tex]\frac{1}{2}[/tex] × 60 × 5[tex]\sqrt{3}[/tex]
= 30 × 5[tex]\sqrt{3}[/tex]

Having trouble with this. Find the measure of the following arcs or angles.
Answers
The missing angle ∠APB, angle ∠CPD, and angle ∠EPA will be 65°, 77°, and 77° respectively.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The diagram is given below.
The angle ∠BPC is 38° and the angle ∠DPE is 103°.
Then the missing angle will be
Angle ∠CPD and angle ∠DPE are linear angles. Then we have
∠CPD + ∠DPE = 180°
∠CPD + 103° = 180°
∠CPD = 77°
Similarly, angle ∠APB, angle ∠BPC, and angle ∠CPD are linear angles. Then we have
∠APB + ∠BPC + ∠CPD = 180°
∠APB + 38° + 77° = 180°
∠APB = 65°
Then the complete circle makes 360°. Then we have
∠APB = 360° - 65° - 38° - 77° - 103°
∠APB = 77°

I need help to find the equation and measures pls help me.
Answers
Answer:
Equation: 2x + x = 180
x = 60
∠GFH = 120
∠CBD = 60
Step by step:
Use 2x + x = 180 because the angles are on a straight line meaning they have a sum of 180:
2x + x = 180
3x = 180
3x/3 = 180/3
x = 60
Now just substitute:
∠CBD = x = 60
∠GFH = 2x = 120

Now
Consider

We know that

Using this we can write
[tex] {3}^{4m - 1} = \frac{ {3}^{4m} }{ {3}^{1} } [/tex]

a) $49,000
b)$75,000
c)-49,000
d)$125,000
Answers
Answer:
The answer is a.) $49,000
Step-by-step explanation:
i just took the test!!
Given that the company estimates the probability that the new can opener will be will be successful is 5/8. If it is successful, it would be able to make $200,000. The company would make nothing if it were unsuccessful. The development costs for the can opener are $76,000. The expected value is $49000.
What is expected value?Expected value is the return you can expect for some kind of action.
The formula for the Expected Value is: ΣX.P(X) .
The amount earned by the company if the new can opener is successful = Revenue of the company - amount invested = $200,000 - $76,000 = $124,000
Probability that the new can opener will be successful = 5/8
Amount earned/ lost if the new can opener is not successful = $0
Probability that the new can opener will not be successful = 1 – 5/8 = 3/8
Expected value = amount earned if the new can opener is successful * Probability that the new can opener will be successful + Amount earned/ lost if the new can opener is not successful * Probability that the new can opener will not be successful
= 124,000 * 5/8 + 0 * 3/8

A triangle has one angle that measures 50° and one angle that measures 40°.
What kind of triangle is it?
A.isosceles triangle
B.obtuse triangle
C.right triangle
D.equiangular triangle
Answers
Answer:
Right triangle
Step-by-step explanation:
If the triangle has one angle that measures 50 degrees and another angle that measures 40 degrees, then the last angle must measure 90 degrees because the 3 angles of any triangle add up to 180, so we can set up the following:
180 - (50 + 40) = 90 degrees.
Any triangle that has a 90 degree angle is automatically a right triangle.
Hope this helps!
________________________________________________________
Option AAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as an isoceles triangle, two angles must be of same measure. Thus, there are two possibilities.
⇒ 50 + 40 + 40 = 180 [Angle 2 = Angle 3]
-------------- Or -------------
⇒ 50 + 40 + 50 = 180 [Angle 1 = Angle 3]
Possibility-1:
⇒ 50 + 40 + 40 = 180⇒ 50 + 80 = 180⇒ 130 = 180 (False)Possibility-2:
⇒ 50 + 40 + 50 = 180 ⇒ 100 + 40 = 180 ⇒ 140 = 180 (False)Therefore, the triangle cannot be an isoceles triangle.
________________________________________________________
Option BAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as an obtuse triangle, the third angle must be a measure greater than 90°. Therefore,
⇒ 50 + 40 + (x > 90) = 180⇒ 90 + (x > 90) = 180⇒ (x > 90) = 180 - 90⇒ (x > 90) = 90 (False)This is false because 90 is not greater than 90. Therefore, the triangle is not an obtuse triangle.
________________________________________________________
Option CAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as a right triangle, the third angle must be a measure equivalent to 90°. Therefore,
⇒ 50 + 40 + 90 = 180⇒ 90 + 90 = 180⇒ 180 = 180 (True)Therefore, this triangle is a right triangle.
________________________________________________________
Option DAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as an equiangular triangle, all the angles must be equivalent (60°). Therefore,
⇒ 1st angle = 2nd angle = 3rd angle⇒ 50 = 40 = 3rd angle (False, because 50 is not equivalent to 40)Therefore, this triangle is not an equiangular triangle.
________________________________________________________
In conclusion, we can conclude that Option C (Right triangle) is correct.

What is the surface area of the cylinder with a raidus of 4 and a high of 10 square meters? Use 3.14 for pi.
Answers
Answer:
351.68 m²
Step-by-step explanation:
surface area of cylinder = 2πrh + 2πr²
r = 4m
h = 10m
2πrh + 2πr² = 2*π*4m*10m + 2*π*(4m)² = 2*3.14*4m*10m + 2*3.14*4m*4m = 351.68 m²
The four small circles are identical. The total area of the small circles is 64pi square inches. What is the area of the larger circle? Write your answer in terms of pi .
Answers
Answer:
64 in²
Step-by-step explanation:
I did not ever do a problem like this, however this is the beauty of math, you can easily reverse engineer it.
Remember,
A = [tex]\pi r^2[/tex]
And if we have 4 circles that means the area of one circle is 1/4th the total
So,
[tex]A=\frac{\pi r^2}{4}[/tex]
Assuming that 16 is the radius squared times 4 lets ignore that squared for now because when going backwards we would get rid of the squared last as that was the first step.
[tex]A=\frac{16\pi }{4}=\frac{4\pi }{1}=4\pi[/tex]
Now lets get it back to by square rooting the 4
[tex]A=\sqrt4\pi =2\pi[/tex]
The radius of one small circle is 2. Therefore; the diameter would be 4 for each. This in mind we know that two small circles diameters make up the radius of the larger circle we will multiply it by two again.
This gives us a final radius of the bigger circle of 8
Therefore, the area of the bigger circle is 8² which simplifies to 64
And a final answer of
64[tex]\pi[/tex] in²

Write the equation of a circle with a radius of length 10 and a center at (-4, -9).
Answer choices in attached image
Answers
Answer:
(x+4)² + (y+9)² = 100
Step-by-step explanation:
We want to find the equation of a circle with a radius of length 10 and a center at (-4, -9).
general equation of circle : (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
the center is at (-4,-9) so h = -4 and k = -9 and the circle has a radius of 10 so r = 10
so we have (x-h)² + (y-k)² = r²
h = -4 , k = -9 and r = 10
(x-(-4))² + (y-(-9))² = 10²
==> apply double negative sign rule and remove parenthesis for -(-4) and -(-9)
(x+4)² + (y+9)² = 10²
==> simplify exponent
(x+4)² + (y+9)² = 100
and we are done!
Answer:
Option D
Step-by-step explanation:
Given:
Radius = 10 unitsCenter point = (h, k) = (-4, -9)∴ x coordinate of center point: (h, k) ⇒ (-4, -9)
∴ y coordinate of center point: (h, k) ⇒ (-4, -9)
Equation of circle formula:
⇒ (x - h)² + (y - k)² = r²Substitute the radius in the formula;
⇒ (x - h)² + (y - k)² = r²⇒ (x - h)² + (y - k)² = (10)²Substitute the x and y coordinate in the formula;
⇒ [x - (-4)]² + [y - (-9)]² = (10)² [x coordinate (h): -4; y coordinate (k): -9]⇒ [x + 4]² + [y + 9]² = 100 (Option D)Therefore, Option D is correct.

What is PN?
A. 7
B. 36
C. 70
D. 100
Answers
Answer:
C.) 70
Step-by-step explanation:
The line PN is made up of PK and KN (PN = PK + KN). We also know that PK must equal KN (definition of a parallelogram). Therefore, you can set the value of both lines equal to each other, solve for x, then add them together to find PN.
PN = ?
PK = 5x
KN = n² - 14
PK = KN <----- Both lines must equal one another
5x = n² - 14 <----- Substitute values in
0 = n² - 5x - 14 <----- Subtract 5x from both sides
0 = (x - 7)(x + 2) <----- Factor
x = 7 x = -2 <----- Set both parentheses equal to 0
The value for "x" can be 7 and -2. However, it does not make sense to use a negative value in this situation. If we were to plug -2 into the equations, it would result in lines with a negative value. Therefore, "x" must be 7. Next, plug this value in for "x" to find the numerical value of PK and KN.
PK = 5x -----> 5(7) = 35
KN = n² - 14 -----> (7)² - 14 = 35
The fact that these are equal makes sense. Now, add these two numbers to find the value of the overall line.
PK + KN = PN
35 + 35 = 70
Therefore, C.) 70 is the value of PN.
