Find the area of the regular polygon with the given radius or apothem.Shape is a hexagon with 4cm inside

Answers

Answer:

55.43cm^2

Step-by-step explanation:

Area of a hexagon given the apothem =  1/2 x perimeter x apothem

apothem = 4cm

To find the perimeter, take the following steps

4 = x√3

x = 4/√3

Multiply by 2

8√3

Since a hexagon has 6 equal sides, multiply by 6

Perimeter = 48√3

Area = (1/2) x  48√3 x 4 = 55.43cm^2

is this quadrilateral a parallelogram?If yes, state the definition or theorem that justifies your answer.​

Answers

Answer:

SOLUTION: Yes; one pair of opposite sides are parallel and congruent. From the figure, one pair of opposite sides has the same measure and are parallel. By the definition of congruence, these segments are congruent. By Theorem 6.12 this quadrilateral is a parallelogram.

Answer:

Below.

Step-by-step explanation:

The definition of a parallelogram is a 4 sided figure  with 2 pairs of oppsoite parallel sides.

One of the properties of a parallelogram is that opposite sides are congruent.

In this figure the opposite sides are both parallel and congruent, so it must be a parallelogram.

The probability of getting a blue marble is 0.15.

What is probability?

The probability of an event is a number that indicates how likely the event is to occur.

Given that, a  bag contains marbles of four different colors: 8 blue marbles, 24 red marbles, 16 green marbles and 4 yellow marbles,

We need to find the probability of picking a blue marble at random out of the bag,

Probability(Event) = Favorable Outcomes / Total Outcomes

Favorable Outcomes = 8

Total Outcomes = 52

Therefore,

P(blue marble) = 8/52 = 0.15

Hence, the probability of getting a blue marble is 0.15.

Answer: $7,488

Step-by-step explanation:

For answer B:

The formula for the new balance would be A=P(1 + r)t

A = new balance

P = principal balance -> $900

r = rate (in decimal form)

t = time in years -> 8 years

To find the rate, convert 4% to decimal  

4/100 = 0.04

A=P(1+ r)t  

A=900(1+0.04)8

A=900(1.04)8

Answer:

m∠C = 26°

m∠D = 108°

m∠E = 46°

Step-by-step explanation:

Set up the equation adding the expressions together to equal 180 (sum of all angles in a triangle)

(2x) + (x+3) + (5x-7) = 180

Remove the parentheses

2x + x+ 3 + 5x - 7 = 180

Add like terms

8x - 3 -7 = 8x -4 = 180

8x - 4 = 180

Add 4 on each side to cancel it out on the right

8x - 4 = 180

     +4   = +4

8x = 184

Divide each side by 8 to get the variable by itself

8/8 =1    184/8 = 23

x = 23

Substitute x in eac expression

2x = 2(23) = 46°

x + 3 = 23 + 3 = 26°

5x - 7 = 5(23) - 7 = 115 -7 = 108

Chek it by adding all the degrees to make sure it equals 180

46 + 26 + 108 = 72 + 108 = 180

If the mean of A and B is 20 , the mean of B and C and the mean of A,B and C us 18 . What is the mwan of A and C

Answers

Answer:

the mean of A and C is 10

Step-by-step explanation:

Given that

The mean of A and B is 20

The mean of B and C is 24

And, the mean of A, B and C is 18

We need to find out the mean of A and C

Since the mean of A and B is 20

So, a + b = 20 × 2

= 40

Likewise for B and C it is 48

And, for A, B and C, it is 54

So,

a + b = 40

b + c = 48

a + b + c = 54

So if we put the value of b + c in the above equation

a + 48 = 54

a = 6

b = 34

c = 14

Now the mean of the A and C is

= (6 + 14) ÷ 2

= 10

Hence, the mean of A and C is 10

Answers

Answer:

Answer is B: (-sqrt(3/2 , -1/2)

Step-by-step explanation:

First convert radians to degrees

theta = (7pi/6)*(180/pi)

=210 degrees

Cos(210 degrees)= -sqrt3/2

Thats the x coordinate

sin(210 degrees)= -1/2

thats the y coordinate

Answer:

The corresponding point on the unit circle for the radian measure is [tex](\frac{\sqrt{3} }{2},\frac{1}{2})[/tex]

Step-by-step explanation:

What is unit circle?

A unit circle is typically drawn around the origin (0,0) of a X,Y axes with a radius of 1.

What is radian measure?

One radian is the measure of a central angle that intercepts an arc s equal in length to the radius r of the circle.

The radian measure is,

α=[tex]\frac{7\pi }{8}[/tex]

Changing to degree measure,

[tex]\frac{7\pi }{6} *\frac{180}{\pi } \\=210^{o}[/tex]

The measure on the unit circle is,

(cos [tex]\alpha[/tex] , sin [tex]\alpha[/tex])=(cos 210 , sin 210)

The height in feet,h , of a model rocket t seconds after launch is given by the equation h(t) = 3+70t-16t^2.

Answers

Answer:

speed of the rocket is 6feet

Step-by-step explanation:

Complete question

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?

Note that the average rate is also known as the speed

Average rate = h(3)-h(1)/3 - 1

h(3) = 3+70(3) - 16(3)^2

h(3) = 3 + 210 - 144

h(3) = 69

h(1) = 3+70(1) - 16(11)^2

h(1) = 3 + 70 - 16

h(1) = 73 -16

h(1) = 57

Average rate = 69-57/3-1

Average rate = 12/2

Average rate = 6ft/s

This shows  that the speed of the rocket is 6feet

Workout the number of chickens on the farm


Help plzz. ​

Answers

Answer: 70 chickens

Step-by-step explanation:

7:2

Chickens to ducks

5:9

Ducks to pigs.

There are 36 pigs. 9 is the ratio of pigs.

5 : 9

? : 36

9 x 4= 36

So multiply 5x4 to find the total ducks

=20 ducks

7 : 2

? : 20

So, 2x10 is 20 (ducks)

So 7x10 to find the chickens

(You have to balence out the sides and keep it equal

So if one side is multiplied by 10, the other is too)

7x10

= 70 chickens

The number of chickens in the farm is 70 chickens

The ratio of chickens to ducks is

7:2

The ratio of ducks to pigs is

5:9

There are 36 pigs in the farm

The first step is to calculate the total number of ducks

9-5

= 4

= 5×4

= 20 ducks

The next step is to calculate the number of chickens

= 7×10

= 70 chickens

Hence there are 70 chickens in the farm

(Lamda) Represents what?? An electromagnet is a device that uses an electric current to produce a magnetic field.Electromagnets are typically composed of a piece of metal wrapped with wire and connected to a battery. The battery provides the electric current, and the loops or coils of wire enhance the magnetic field. The more loops there are, the stronger the magnetic field.When electric current flows through the electromagnet, the metal core becomes magnetized, so it possesses a north pole and a south pole.Motors place electromagnets inside of permanent magnets as shown below.However, motors are designed so that the polarity of the electromagnet constantly flips. That is, the north pole becomes the south pole, and the south pole becomes the north pole, every time the electromagnet turns 180 degrees.Why is it designed this way? A. to conserve the energy in the battery B. to constantly polarize the field magnet C. so the electromagnet will continuously turn D. so the magnetic field will get stronger Let x represent the number of batteries and y represent the cost of the batteries.
