Step-by-step explanation:

Polygon ABCDE is a regular hexagon. The sum of the measures of the interior angles is (n - 2)180 = (6 - 2)180 = 4(180) = 720. Since it's a regular hexagon, each interior angle measures 720/6 = 120 deg.

For the interior angle, m<CDE = 120

On the exterior of the polygon, m<CDJ = 136

m<CDE + m<CDJ + m<EDJ = 360

120 + 136 + m<EDJ = 360

m<EDJ + 256 = 360

m<EDJ = 104 deg

Triangle EHG is regular. The sum of the measures of the angles of a triangle is 180. For a regular triangle, each angle measures 60 deg.

m<EGH = 60

For exterior angle m<HGJ = 220

m<HGJ(exterior) + m<EGH + m<EGJ = 360

220 + 60 + m<EGJ = 360

m<EGJ + 280 = 360

m<EGJ = 80

m<EGJ = m<GED, so

m<GED = 80

Polygon DEGJ is a quadrilateral. The sum of the measures of its interior angles is 360 deg.

m<EGJ + m<GED + m<EDJ + m<GJD = 360

80 + 80 + 104 + m<GJD = 360

m<GJD + 264 = 360

m<GJD = 96 deg

Answer:

The measure of angle GJD is 96°.

Step-by-step explanation:

It is given that HGJ=220° on the exterior of the polygon, EGJ is congruent to GED, and CDJ=136° on the exterior of the polygon.

Each side and each interior angle of a regular polygon are same.

It is given that ABCDEF and EHG are regular polygons. It means each interior angle of regular hexagon ABCDEF is 120° and each interior angle of regular triangle EHG is 60°.

[tex]\angle EGH+\angle EGJ+\angle HGJ(exterior)=360^{\circ}[/tex]

[tex]60^{\circ}+\angle EGJ+220^{\circ}=360^{\circ}[/tex]

[tex]\angle EGJ+280^{\circ}=360^{\circ}[/tex]

[tex]\angle EGJ=360^{\circ}-280^{\circ}[/tex]

[tex]\angle EGJ=80^{\circ}[/tex]

[tex]\angle GED=\angle EGJ=80^{\circ}[/tex]

[tex]\angle CDE+\angle EDJ+\angle CDJ(exterior)=360^{\circ}[/tex]

[tex]120^{\circ}+\angle EDJ+136^{\circ}=360^{\circ}[/tex]

[tex]\angle EDJ+256^{\circ}=360^{\circ}[/tex]

[tex]\angle EDJ=360^{\circ}-256^{\circ}[/tex]

[tex]\angle EDJ=104^{\circ}[/tex]

The sum of all interior angles of a quadrilateral is 360°.

[tex]\angle GED=\angle EGJ+\angle EDJ+\angle GJD=360^{\circ}[/tex]

[tex]80^{\circ}+80^{\circ}+104^{\circ}+\angle GJD=360^{\circ}[/tex]

[tex]264^{\circ}+\angle GJD=360^{\circ}[/tex]

[tex]\angle GJD=360^{\circ}-264^{\circ}[/tex]

[tex]\angle GJD=96^{\circ}[/tex]

Therefore the measure of angle GJD is 96°.

Answer:

1505 cubic centimeters

Step-by-step explanation:

Lengths are related by scale factor "k"

Volumes are related by scale factor "k^3"

From large to small:

What multiplied by 18, gives us 6? We can write:

18(k)=6

k = 6/18 = 1/3

So scale factor is 1/3

Now in terms of volume, the larger is given as 40, 635, so we can set up:

40,635 * k^3 = smaller volume

we know k = 1/3, so

40,635 * (1/3)^3 = smaller volume

Thus, smaller volume = 40,635 * (1/3)^3 = 1505

To estimate the mouse population after 30 days using the given model, M(t)=200(1.2)^t, evaluate the expression with t=30, which results in approximately 47,475 mice.

The student is asking how many mice will be in the building after 30 days according to the exponential growth model M(t) = 200(1.2)^t, where t is the time in days and M(t) is the population of mice at time t. To find the answer, we simply plug the value of 30 days into the model to get M(30) = 200(1.2)^30.

Calculating the expression:

First, calculate 1.2 raised to the power of 30, which gives us approximately 237.3769.

Then, multiply that by the initial population of 200 mice, yielding a result of approximately 47,475.38.

Therefore, after 30 days, assuming no mice die, there will be approximately 47,475 mice in the building.

Answer:

10 necklaces =  50 rocks

15 necklaces = 75 rocks

20 necklaces = 100 rocks

25 necklaces = 125 rocks

Step-by-step explanation:

A table that shows the number of shiny rocks used for 10, 15, 20, and 25 necklaces:

| Number of necklaces | Number of shiny rocks used |

| 10 | 50 |

| 15 | 75 |

| 20 | 100 |

| 25 | 125 |

To calculate the number of shiny rocks used, we simply multiply the number of necklaces by the number of shiny rocks per necklace. For example, to calculate the number of shiny rocks used for 10 necklaces, we multiply 10 by 5:

10 necklaces * 5 shiny rocks/necklace = 50 shiny rocks

We can do the same calculation for 15, 20, and 25 necklaces to get the following results:

15 necklaces * 5 shiny rocks/necklace = 75 shiny rocks

20 necklaces * 5 shiny rocks/necklace = 100 shiny rocks

25 necklaces * 5 shiny rocks/necklace = 125 shiny rocks

Therefore, the table above shows the number of shiny rocks used for 10, 15, 20, and 25 necklaces.

Answer:

16b^4/81

Step-by-step explanation:

For this case we have that by definition:

[tex]Sec (a) = \frac {1} {cos (a)}[/tex]

Then, we can rewrite the expression as:

[tex]Sec (120) = \frac {1} {cos (120)}[/tex]

[tex]cos (120) = cos (180-60) = - cos (60) = - \frac {1} {2}[/tex]

So:

[tex]Sec (120) = \frac {1} {- \frac {1} {2}}\\Sec (120) = - 2[/tex]

Answer:

-2

The exact value of sec 120° is -2 as secant function is the reciprocal of the cosine function,

The secant function is the reciprocal of the cosine function, so we can find sec 120° by finding the reciprocal of cos 120°.

First, let's determine the value of cos 120°.

We know that cos 120° is negative in the unit circle, so we need to find the cosine of the reference angle, which is 60°.

In the unit circle, at 60°, the cosine value is 1/2.

Since cos 120° is negative, the value is -1/2.

Now, we can find the exact value of sec 120° by taking the reciprocal of -1/2:

sec 120° = 1 / (cos 120°) = 1 / (-1/2) = -2.

Therefore, the exact value of sec 120° is -2.

a)Each egg requires 0.5 cups of sugar in Grandma's recipe.

b)The ratio of baking powder to salt is 3:1.

a) The recipe uses 2 cups of sugar and 4 eggs. To find out how many cups of sugar are needed per egg, we divide the total cups of sugar by the number of eggs:

2 cups of sugar / 4 eggs = 0.5 cups of sugar per egg

So, 0.5 cups of sugar are needed for each egg.

b) Ratio of baking powder to salt

The recipe calls for 3/4 teaspoon of baking powder and 1/4 teaspoon of salt. To find the ratio of baking powder to salt, we divide the amount of baking powder by the amount of salt:

(3/4) teaspoon of baking powder / (1/4) teaspoon of salt = 3

Answer:

45°

Step-by-step explanation:

Imagine a waistband stretched around the middle of an apple, horizontally.

The waistband could be represented by the circumference of the apple, with a central angle of 360°.

Divide this central angle by 8, obtaining 45°.  Each piece of apple is measured by a central angle of 45°.

To find the angle measure of each of the 8 pieces of the apple, divide the total degrees in a circle by 8, resulting in each piece having an angle measure of 45 degrees.

To find the angle measure of each piece, we divide the circle into 8 equal slices.

Each slice corresponds to an angle of 360 degrees (the total degrees in a circle) divided by 8, which equals 45 degrees for each piece.

Therefore, the angle measure of each piece of the apple is 45 degrees.
