Answer:

GL = square root of 2 = √2

Step-by-step explanation:

Given: GHJK is a square and its diagonals intersect at L

GJ and HK are its two diagonals.

We know that in a square diagonals bisect each other and if length of side is a, then length of its diagonal = √2 a.

Therefore, GJ=HK = √2×2

Since, diagonal intersect at L , L is mid point of GJ and HK

Therefore, GL = √2×2/2 = √2

Hence, GL = square root of 2

Answer:

312 cm²

Step-by-step explanation:

The figure is composed of a rectangle and 2 congruent triangles

area of rectangle = 16 × 12 = 192 cm²

area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × 12 × 10 = 12 × 10 = 120 cm²

Area of figure = 192 + 120 = 312 cm²

Give the guy above me brainliest tho :)

The height of the rhombus is equal to 9 centimeters.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

To calculate the height of the rhombus, we will follow the steps below;

write the formula for calculating the area of a rhombus

area of a rhombus = b × h

where h is the height of the rhombus and b is the base of the rhombus

From the question given,  area of the rhombus = 12 square centimeters  

and length of sides of the rhombus is 8 centimeters.

we can now proceed to insert the values into the formula and then solve for h

area of a rhombus = b × h

i.e.  12 = 4 × h

Divide both-side of the equation by 4

12/4  =  4/4 × h

3 =  1× h

3 = h

h =3 centimeters

The height of the rhombus is equal to 3centimeters.

Answer:

[tex]x=\frac{5}{k}[/tex]

Step-by-step explanation:

Given expression is,

[tex]\text{log}_{3^k}243=x[/tex]

By using the law of logarithm,

[tex](3^k)^x=243[/tex]

[tex]3^{kx}=243[/tex]

[tex]3^{kx}=3^5[/tex]

By comparing exponents on both the sides of the equation,

[tex]kx=5[/tex]

[tex]x=\frac{5}{k}[/tex]

Therefore, [tex]x=\frac{5}{k}[/tex] will be the answer.

Answer:

A

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

    = πr² × [tex]\frac{150}{360}[/tex]

    = π × 12² × [tex]\frac{15}{36}[/tex]

    = 144π × [tex]\frac{5}{12}[/tex] ( cancel 144 and 12 by 12 )

    = 12π × 5

    = 60π

     ≈ 188.5 Km² ( to the nearest tenth ) → A

Answer:

Step-by-step explanation:

11) strategy:  since they tell us. indirectly,  that the length of  JK is the same as LM then we can set those two equal, solve for X  and then.. when we have X we can figure out the lenght of JK  and LM and then just divide that by 2 go get PK  ( :0 Player Killer ???  no , not that PK)    

solve JK and LM

3x + 23 =9x-19

42 = 6x

7 = x

now that we know x = 7 plug it into either equation to come up with the length of JK or LM .  I'll pick JK just b/c it was 1st

3(7) + 23 = JK

21+23 = JK

44 = JK

now take half of 1/2*JK= 22  that is PK    ( are you sure that 's not player killer?)

PK = 22

12) strategy: set the two arcs BG and GC equal and solve for X, then plug x into either equation and the multiply the answer by 2 to find arc AB

9x-20 = 5x + 28

4x = 48

X = 12

9(12) -20 = BG

88 = BG

2*88 + AB

176 = AB

13) done

14)  strategy: find the angle at L,  and that will also be the arc of MK

copy and past the below helpful trig functions into your computer

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

copy and past the above :

use which ever trig function you want , we have all the sides of the triangle, I'll use CAH

Cos(Ф) = 9/15

Ф = arcCos(9/15)

Ф = 53.13010°

arc MK = 53.13010°

15)   strategy:  arc JK is just 2 times MK

2*MK = 106.26020°

arc MK = 106.26020°

16) find arc JPK   strategy:  JPK is just the remaining part of a full circle of 360 - MK  = 253.7397°

arc JPK = 253.7397°

Answer:

C.

Step-by-step explanation:

Reorder the data set, from least to greatest.

3, 5, 7, 8, 9, 9, 10, 11, 12

Mean: 8.2 -> you get this by adding up all the numbers in the data set by how many numbers in the data set. For example, 3+5+7+8+9+9+10+11+12= 74 divide by 9 (the numbers in the data set) = 8.2 (repeated infinitely).

Median: 9 -> you get this by finding the number in the middle of the data set, which is why you have to reorder the data set for the beginning to make this easier.

Mean (with 45): 11.9 -> 119 when you add up all the numbers, then divide by 10 because that's have many numbers in the new data set.

Median (with 45): 9 -> When there are two numbers in the middle of the data set, add them up and divide by two. For example, 9+9=18/2= 9
