Answer:

11.5 meters

Step-by-step explanation:

Since we know the perimeter of a hexagon, and we know in a hexagon there are 6 equal sides, then we can find the length of each side.

P = 6*x, where P is the perimeter and 6 is the total amount of sides and x is the length of each side. Plug in 69 for P and solve your equation.

69 = 6x

Divide by 6 on both sides to isolate x

11.5 = x

Hope this helps

Answer:

Each side is 11.5 m

Step-by-step explanation:

A hexagon is a 6 sided figure

The  figures has sides that are all the same length

P = 6s where s is the side length

69 = 6s

Divide each side by 6

69/6 = 6s/6

11.5 =s

Each side is 11.5 m

Answer:

189

Step-by-step explanation:

step 1: calculate area of rectangle

Area = l × b

= 10× 15

= 150

step 2: calculate area of half a circle

Area = 1/2 (π.r²)

= 1/2 (22/7 × 5²)

=157/4

step 3: Add the area of rectangle and half a circle together

Area = 157/4 + 150

= 189.26

rounded off to the nearest whole = 189

It can be deduced from the scale computed that the model will be 648 inches.

Since 1 foot = 12 inch

18 feet = 12 × 18 = 216 inches.

In this case, since 1 inch = 3 feet was used to create their model, the model in their scenario will be:

= 216 × 3

= 648 inches.

In conclusion, the model is 648 inches.

Answer:

x= 6 and y=5. i think

Step-by-step explanation:

because the height is at the number 5 and the arrow. same goes for the x

this is for the picture

15 - 3 + 10 × 5 ÷ 5 = ? Hence, 48 is the correct answer.

By inserting codes and then using BODMAS Rule:

15 × 3 - 10 ÷ 5 + 5

15 x 3 = 45. Now 10 divided by 5 is 2 and keep the other 5 so:

= 45 - 2 + 5 = 48

Answer: I’m not sure if I’m right, but I just divided 450 by 5 and got 90! I tried using the calculators for this sort of problems but none were any help. I think B is the one to go with!

A partir de las informaciones de la pregunta, se encontró que el lado del primer cuadrado es igual a 7 cm.

The square is a quadrilateral that has all sides (x) equals and angles equal to 90°. The perimeter of a square is equal to the sum of sides, so, p=x+x+x+x=4x.  And the area of square formula is A=x².

Therefor, the AREA 1= x².

From problem data, you can write the area 2.

                   AREA 2 =(x+3)*(x+3)=x²+51, then

                                    x²+3x+3x+9=x²+51

                                    6x=51-9

Answer:

I can't see what the options are, but any fraction equal to 1/2 will be equal to 3:6.

Step-by-step explanation:

Treat a ratio like a fraction. In this case, 3 is the numerator and 6 is the denominator. If you reduce 3/6, you get 1/2. Fractions/ratios also equal to 1/2 or 3/6 are:

2:4

4:8

If any of these ratios are not one of the options, comment below with the choices and I will help you narrow it down.

Answer:

6:12,

Step-by-step explanation:

equivalent ratios are when all numbers in a ratio can be divided or multiplied to get a whole number. for example, 3:6. the 3 can be multiplied by 2 to get 6, and the 6 can be multiplied by 2 to get 12.

Answer:

The answer is 6.72

Step-by-step explanation:

Here, if we double the amount of grapes and money we get,

2 (500) = 1000g

2 (2.8) = 5.6

So, for 1000 g it costs 5.6

and for 100 g it costs 0.56

We need to find the cost 1.2 kg of grapes

So,

5.6 + 0.56 + 0.56 = 6.72

Thus, The cost of 1.2 kg of grapes is 6.72

-TheUnknownScientist 72

Answer:

6.72

Step-by-step explanation:

Cost of 500 grams = 2.8

Cost of 1 gram = 2.8/500 = 0.0056

Cost of 1.2 kg = ?

1.2 kg = 1,200 g

Cost of 1.2 kg:

= 0.0056 × 1,200

= 6.72

Answer:

I think you need to draw it with graph.

Step-by-step explanation:

Kareem plans to get eight hours of sleep but looses a half hour of sleep every time his dog barks. Therefore between his hours of sleep (h) and number of dog barks (b) will be:

h = 8 – (b/2)

So that if b = 0,

Kareem’s hours of sleep:

h = 8-(0/2)

= 8-0

= 8

if b = 5

h = 8 -(5/2)

h = (16-5)/2

h = 11/2

h = 5.5

Step-by-step explanation:

The angle between the sides 6 feet and 10 feet is 93.82 degrees by using the cosine rule.

Trigonometry deals with the relationship between the sides and angles of a triangle.

A tree is growing on a hill.

In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a point 6 feet off the ground.

The wire is anchored to the ground 10 feet from the base of the tree.

We know that the cosine rule is given as

[tex]\rm Cos \theta = \dfrac{a^{2} +b^{2} - c^{2} }{2ab}[/tex]

We have

a = 6

b = 10

c = 12

Then angle will be

[tex]\rm Cos \theta = \dfrac{6^{2} +10^{2} - 12^{2} }{2*6*10}\\\\\rm Cos \theta = \dfrac{36+100-144}{120}\\\\\rm Cos \theta = \dfrac{-8}{120}\\\\\theta \ \ \ \ \ = cos^{-1} \dfrac{-8}{120} \\\\\theta \ \ \ \ \ = 93.82[/tex]
