Answers

Answer 1

Answer:

4 edges

Step-by-step explanation:

the shape is a cube

Answer 2

Answer: 12

Step-by-step explanation:

Euler’s formula: F + V - E = 2

6 + 8 - E = 2

14 - E = 2

You find E by subtracting 14 with 2

14 - 2 = 12

E = 12

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are right angled, obtuse, acute, scalene, isosceles, equilateral triangle.

Trigonometric identities are used to show the relationship between the sides and the angles in a right angled triangle. Below are some trigonometric identities:

sin(θ) = opposite / hypotenuse; cos(θ) = adjacent / hypotenuse; tan(θ) = opposite / adjacent

The hypotenuse is the longest side in the triangle.

From the image attached:

sin(α) = opposite side / hypotenuse side

sin(α) = 7 / 25

Two recreational basketball teams, Eagleton and Hawkville, wanted to compare the heights of their players in inches.

The heights of Eagleton's basketball players are 70, 71, 72, 74, 74, 75, and 75. The mean height of the Eagleton players is 73 inches

The heights of Hawkville's basketball players are 70, 70, 71, 72, 72, 72, and 77. The mean height of the Hawkville players is 72 inches.

Which statement is true?


Team Hawkvilles's players heights vary the same amount as Team Eagleton's players heights.

The range of Eagleton's players heights is greater than the range of Hawkville's players heights.

Team Hawkville's players heights vary more than Team Eagleton's players heights.

Team Eagleton's players heights vary more than the heights of Hawkville's players.

Answers

Answer:

Option C

Step-by-step explanation:

Given -

Height of the Eagleton's basketball players are 70, 71, 72, 74, 74, 75, and 75.

The mean height of Eagleton's basketball players is 73 inches

Heights of Hawkville's basketball players are 70, 70, 71, 72, 72, 72, and 77. The mean height of the Hawkville players is 72 inches

The range of any given data set is the difference in the maximum and minimum value the frequencies with in the data set.

The range of Hawkville's basketball players is 77-70 = 7

The range of Eagleton's basketball players is 75-70 = 5

Hence, the height of Hawkville's basketball players vary more as compared to the height of players of Eagleton.

Answer A hope this helps

Let measure of angle B be 18 degrees and BC = 9. Find the length of AC, BA and the measure of angle C. Round to 1 decimal place when needed. Show all of your work.

Answers

Answer:

m∠C = 72°

BA = 8.6

AC = 2.8

Step-by-step explanation:

We can start by finding the sum of all angles in a triangle to find angle C. The sum of all angles is 180°, so we can write the equation:

m∠A + m∠B + m∠C = 180°

And substitute what we have:

90° + 18° + m∠C = 180°

108° + m∠C = 180°

m∠C = 72°

In order to find the side BA, we can use trig functions. We are given the hypotenuse and we are looking for the side adjacent to ∠B. The trig function that relates the two is cosine. We can set up the equation as follows:

cos(∠B) = [tex]\frac{BA}{BC}[/tex]

cos(18°) = [tex]\frac{BA}{9}[/tex]

9 * cos(18°) = BA

BA ≈ 8.559508647

And when we round, we get:

BA = 8.6

In order to find the side AC, we can use trig functions. We are given the hypotenuse and we are looking for the side opposite to ∠B. The trig function that relates the two is sine. We can set up the equation as follows:

sin(∠B) = [tex]\frac{AC}{BC}[/tex]

sin(18°) = [tex]\frac{AC}{9}[/tex]

9 * sin(18°) = AC

AC ≈ 2.781152949

We can round this to:

AC = 2.8

Answers

Answer:  D) 38 square cm

A slightly more accurate value is 38.28 cm^2, when using pi = 3.14

=================================================

Explanation:

The vertical height of the rectangle is 4 cm, which forms the diameter of the semicircle. The diameter cuts in half to 4/2 = 2, which is the radius.

The area of a full circle with radius r = 2 cm is approximately pi*r^2 = 3.14*2^2 = 12.56 square cm.

Cut that in half to get (12.56)/2 = 6.28 square cm. This is the approximate area of the semicircle.

--------

The area of the rectangle is length*width = 6*4 = 24 square cm.

The triangle has its bottom portion of 4 cm (because 10-6 = 4) and its height is 4 cm, so we get the triangle area of base*height/2 = 4*4/2 = 8 square cm.

The last thing we do is add up all the results we got:

6.28 + 24 + 8 = 38.28

That rounds to 38 square cm when rounding to the nearest whole number.

Answers

Complete question :

En France, en 1900, la taille moyenne des femmes était de 1,54 m et celle des hommes de 1,66 m. Entre

1900 et 2010 ces tailles moyennes ont augmentées d'environ 5,55%.

Calculer, en mètres, l'arrondi au centième des tailles moyennes des femmes et des hommes en 2010.​

Répondre :

Femmes = 1,63

Hommes = 1,75 m

Explication étape par étape:

Étant donné que :

Taille moyenne en 1900:

Hommes = 1,66 m

Femmes = 1,54 m

Pourcentage d'augmentation de poids d'ici 2010 = 5,55%

1 + 5,55% = 1 + 0,0555 = 1,0555

D'où,

Taille des femmes en 2010:

1,0555 * 1,54 = 1,62547 = 1,63 m

Pour la taille des hommes en 2010:

1,0555 * 1,66 m = 1,75213 = 1,75 m

A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Total students samples=30

Students answered yes =11

The proportion of students who have at least one cat

Step-by-step explanation:

Given:

Number of fabric sample = 6 sample

Number of floral sample from all samples = 2 samples

Find:

Probability of selected sample is floral

Computation:

Probability of a sample = Favorable outcome / Total outcomes

Probability of selected sample is floral = Number of floral sample / Number of fabric sample

Probability of selected sample is floral = 2 / 6

Probability of selected sample is floral = 1 / 3

Find the area of the shaded region

Answers

Answer:

40

Step-by-step explanation:

area of shaded region = area of whole figure - area of non shaded region

area of whole figure: The whole figure is a rectangle

The area of a rectangle can simply be calculated by multiplying the width by the length

The given width is 10ft and the given length is 8ft

Hence area of whole figure = 10 * 8 = 80ft²

Area of non shaded region: the non shaded region also creates a rectangle

Like stated previously the area of a rectangle can simply be calculated by multiplying the width by the length

The given width is 5ft and the given length is 8ft

Hence, area of non shaded region = 5 * 8 = 40ft²

Finally we can find the area of the shaded region.

We can easily do this my subtracting the area of the nonshaded region from the area of the whole figure

If we have identified that the area of the whole figure is 80 and the area of the non shaded region is 40

Then, area of shaded region = 80 - 40 = 40ft²

A car travelled at 50 km/hr for 3 hours How far did the car travel?

Answers

Answer:

25km

Step-by-step explanation:

50 km = x km

1 hr        3 hrs

From there, you cross-multiply and solve for x.

(50 km)*(3 hrs) = (x km)*(1 hr)

x km = (50)*(3)/(1) = 150km

Now, your other question can be answered the exact same way. 30 minutes is the same as 1/2 of an hour, so just put 0.5hrs in where the 3hrs was in the previous problem. So to show you how it works once more, here are your calculations:

50 km = x km

1 hr        0.5 hrs

(50 km)*(0.5 hrs) = (x km)*(1 hr)

x km = (50)*(0.5)/(1) = 25km

length of rectangle = 4 units

Height of rectangle = 2x + 6 units

To find:

Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.

Steps:

Perimeter of rectangle = 2(L + B)

                                      = 2( 4 + 2x + 6 )

                                      = 2( 10 + 2x )

                                      = 2 * 10 + 2 * 2x

                                      = 20 + 4x units

Area of rectangle = L * B

                             = 4 * (2x + 6)

                             = 4 * 2x + 4 * 6

                             = 8x + 24 units²

Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².
