Answer:

hi

Step-by-step explanation:

we can do this with Pthyagorean teorem

[tex] {12}^{2} + {x}^{2} = {15}^{2} \\ 144 + {x}^{2} = 225 \\ {x}^{2} = 225 - 144 \\ {x}^{2} = 81 \\ x = \sqrt{81} \\ x = 9 \: cm[/tex]

BC is 9

Answer:

La longitud del lado del octágono es de 28 unidades.

Step-by-step explanation:

Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:

[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)

A continuación, despejamos [tex]x[/tex] en (1):

[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]

[tex]x = 12[/tex]

Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])

[tex]l = 2\cdot x + 4[/tex]

[tex]l = 28[/tex]

La longitud del lado del octágono es de 28 unidades.

Answer:

h = 3 cm

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated as

V = Ah ( A is the area of the base and h the height )

Here V = 36 and A = 6 × 2 = 12 cm² , then

12h = 36 ( divide both sides by 12 )

h = 3

Answer: 3 cm

Step-by-step explanation:

The formula to solve the volume of a rectangular prism is V = l x w x h

Where V is volume, l is length, w is width, and h is height

Givens are, Volume = 36 cm3

length = 6 cm

width = 2 cm

Now, we will plug in the numbers to the formula

36 cm3 = 6cm x 2cm x h

36 cm3 = 12 cm2 x h

divide 12cm2 on both sides

36cm3/12cm3 = h

h = 3cm

Step-by-step explanation:

Answer:

2140

Step-by-step explanation:

Year one.                         1300

year 2.         120.               1420

year 3.         120.              1540

year 4.         120.              1660

year 5.         120.              1780

year 6.         120.              1900

year 7.         120.              2020

year 8.         120.              2140

or

7 x 120=840

1300 + 840 = 2140

Answer:

13.96

Step-by-step explanation:

length of an arc = theta/360 * 2πr

Given

m<HJK = 50

HJ = 16units

Required

length of arc HK

arc HK = 50/360 * 2(3.14)(16)

arc HK = 5/36 * 100.48

arc HK = 502.4/36

arcHK = 13.96

hence the length of arcHK to nearest hundredth is 13.96

Answer:

there would probably be around 60 rabbits

Answer:

x = 20

Step-by-step explanation:

3/4x = 15

Abby's calculation:

3/4x = 15

Multiply both sides by 3/4

x = 1114

Abby's error was multiplying both sides by 3/4 instead of dividing both sides by 3/4 to get the value of x

Correct calculation:

3/4x = 15

Divide both sides by 3/4

3/4x ÷ 3/4 = 15 ÷ 3/4

x = 15 × 4/3

x = 60/3

x = 20

Check:

3/4x = 15

3/4*20

= (3*20) / 4

= 60/4

= 15

3/4*20 = 15

Answer:

It's exactly the same, except the size

Step-by-step explanation:

Answer:

They are similar because if you look at the length of 2 of the sides that you know

Triangle ABC has side length 1 and 2 or 1:2

CFE has sides length 2 and 4 or 2:4 and 2:4 can also be written as [tex]\frac{2}{4}[/tex] which is a fraction, and fractions can be simplified to 1:2.

So they are similar but just one is bigger then the other.

Answer:

2.99 cm

Step-by-step explanation:

V= [tex]\frac{4}{3}[/tex](pi)(r^3)=113.04cm^3

113.04/ [tex]\frac{4}{3}[/tex](pi) = r^3 = 26.99

r=[tex]\sqrt[3]{26.99}[/tex] = 2.99cm
