Find the area of each sector. Round your answer to nearest tenth
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

Find the area of the following figure.
252 [tex]cm^{2}[/tex]
400 [tex]cm^{2}[/tex]
312 [tex]cm^{2}[/tex]
300 [tex]cm^{2}[/tex]
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
GHJK is a square with diagonals intersecting at L. Given that GH=2 and GL=square root of , complete the statement
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

Show that f(x) = x^2 and g(x) = 1000x^2 grow at the same rate.
Answer:
You do not use the first derivative to find the rate you need to take the limit ratio as x approaches positive infinity. We use positive and not negative infinity because our function is increasing and not decreasing. The ratio ends up being 1/1000 meaning that this a finite non zero number. Which proves that they grow at the same rate

SED
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

A rhombus has side lengths of 4 centimeters and an area of 12 square centimeters. What is the height of the rhombus?
3 cm
6 cm
4 cm
8 cm
Answer:
3cm
Step-by-step explanation:
I got the answer right on my quiz :P
Give the guy above me brainliest tho :)
The height of the rhombus is equal to 9 centimeters.
What is area ?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.

14. Find mMK please :)
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°
