Calcula el área de este hexágono. Datos: -lados 8 cm² -apotema 3'7cm²

Answers

Respuesta:

88,8 cm²

Explicación:

Consideremos un hexágono regular. Su apotema, la distancia más corta entre el centro del hexágono y uno de sus lados, es 3,7 cm y sus lados miden 8 cm.

Primero debemos calcular su perímetro, que es igual a la suma de sus 6 lados.

Perímetro = 8 cm + 8 cm + 8 cm + 8 cm + 8 cm + 8 cm = 48 cm

Luego, podemos calcular el área del hexágono usando la siguiente fórmula:

Area = Perímetro × Apotema / 2

Area = 48 cm × 3,7 cm / 2 = 88,8 cm²

9 ( x - 5 ) = -108 solve for x

Answers

Answer:

x = -7

Step-by-step explanation:

9 ( x - 5 ) = -108

9x - 45 = -108

add 45 to each side of the equation:

9x = -63

divide both sides by 9:

x = -7

Answer:

x = - 7

Step-by-step explanation:

9(x - 5) = - 108

9x - 45 = - 108

9x - 45 + 45 = - 108 + 45

9x = - 63

9x ÷ 9 = - 63 ÷ 9

x = - 7

Answers

Answer:

Its probably too late now but the answer is 83

Step-by-step explanation:

83 is the lowest grade she can make on her last test to finish with an 80 test average.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given that Jamie wants to make an 80, or B, test average in her class.

She scored 75 and 82 on her last 2 tests.

we need to find the  lowest grade she can make on her last test to finish with an 80 test average

Let x be the e  lowest grade she can make on her last test to finish with an 80 test average

75+82+x/3=80

157+x=240

Subtract 157 from both sides

x=83

Hence, 83 is the  lowest grade she can make on her last test to finish with an 80 test average.

In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?
Explain how you found your answer.
Enter the correct answers in the boxes.

Answers

Answer:

150cm²

Step-by-step explanation:

In a trapezoid, the length of one base is equal to its height and the length of the other base is twice its height. If the height is 10 centimeters, what is the area of the trapezoid?

The formula for the area of a trapezoid = 1/2(a + b) h

Where a = Length of the first base

b = Length of the second base

h= height of the trapezoid

h = 10cm

The length of one base is equal to its height

Hence:

a = h = 10cm

The length of the other base is twice its height.

b = 2h

h = 10cm

b = 10 × 2 = 20cm

Therefore, the Area of the Trapezoid =

1/2 (20 + 10)10

1/2 × 30 × 10

= 150cm²

The width of a rectangle is 1units less than the length. The area of the rectangle is 42 units

Answers

Answer:

Step-by-step explanation:

w=l-1

∵A=l×w

∴A=l×(l-1)

⇒42=l²-l

⇒l²-l-42=0 (After subtracting 42 from both sides)

Two factors of 42 that add to give negative 1 :-7+6

∴ (l-7)(l+6)=0

∴ l=7 or l=-6

but remember that length is a scalar quantity, hence l≠6 but l=7.

PLEASE HELP WITH GEOMETRY IM STUCK!?}

Answers

Answer:

13.8

Step-by-step explanation:

Recall the trigonometric ratios

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

Now lets look back at the question

We are given an angle and its adjacent side length (11) and we need to find the hypotenuse

The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x

( remember that cosine = adjacent over hypotenuse )

[tex]cos(37)=\frac{11}{x}[/tex]

step 1 multiply each side by x

[tex]cos(37)*x=xcos(37)\\\frac{11}{x} *x=11[/tex]

now we have [tex]xcos(37)=11[/tex]

step 2 divide each side by cos(37)

[tex]\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\[/tex]

we're left with x = 13.77439

Our last step would be to round to the nearest tenth

We would get that the answer is 13.8

Answer:

G) x = 13.8

Step-by-step explanation:

cos 37° = adj/hyp = 11/x

0.7986x = 11

x = 13.8

In the system of equations
-3.0 - 4y = 4
-52 + y = 2
Is (2, 10) a solution to the system?

Answers

Answer:

No, (2, 10) is not a solution to the system

Step-by-step explanation:

The given set of equations are -

-3X - 4Y = 4 --- Eq(1)

-52X + Y = 2--- Eq (2)

Multiplying equation 2 by 4, we get

-3X - 4Y = 4 --- Eq(1)

4 *(-52X + Y = 2)--- Eq (2)

-3X - 4Y = 4 --- Eq(1)

-208X + 4Y = 8--- Eq (2)

Now we will add equation 1 and 2

-211 X = 12

X = 12/211

Hence, the given set of solution does not fit for the given two equations
