Answer:

D. 6

Step-by-step explanation:

90 - 30 = 60

so :-

10X = 60

then, X= 60÷10

X = 6.

Answer:

Range = 23

IQR= 14.5

Step-by-step explanation:

Range is the biggest number- smallest number

so 30-7=23

IQR - Interquartile range = upper quartile - lower quartile

24-9.5=14.5

Answer: [tex]2+i5,\ 29[/tex]

Step-by-step explanation:

Given

Complex number is [tex]2-i5[/tex]

Its conjugate is obtained by changing the sign of the original number i.e. [tex]2+i5[/tex]

The product of the two numbers is

[tex]\Rightarrow (2-i5)(2+i5)=2^2-(5i)^2\quad \quad [(x+y)(x-y)=x^2-y^2]\\\\\Rightarrow (2-i5)(2+i5)=4-25i^2\\\\\Rightarrow (2-i5)(2+i5)=4+25=29[/tex]

Answer:

49°

Step-by-step explanation:

since its a right angle that just subtract from 90

90-41= 49

Answer:

49

Step-by-step explanation:

Because of the square at O, we know that angle XOZ is a right angle and is 90°.

Since angle XOZ is made up of angle XOY and angle YOZ, we can subtract the measure of angle XOZ by the measure of angle XOY to find the measure of angle YOZ, which is equal to x.

x = 90 - 41

x = 49

Answer:

  (3/2π -(9/4)√3) m² ≈ 0.8 m²

Step-by-step explanation:

The area of the segment is the difference between the area of the sector and the area of the triangle.

  sector area = 1/2r²α . . . . where r is the radius and α is the central angle in radians

  triangle area = 1/2r²·sin(α) . . . . same variable definitions

Then the area of the segment is ...

  segment area = sector area - triangle area

  segment area = (1/2)r²(α -sin(α))

The central angle subtended by the segment is 360° -300° = 60° = π/3 radians

Then the segment area is ...

  A = (1/2)(3 m)²(π/3 -√3/2) = (3/2π -(9/4)√3) m² ≈ 0.8 m²

Answer:

y = (2/3)x + 19/3

Let me know if there are any parts of the process you do not understand.

Step-by-step explanation:

First you need to know what slope is, if you do not let me know and I can explain it in depth.

Now, you can determine if a line is parallel or perpendicular  by its slope.  parallel has the same slope and perpendicular has the negative reciporical, which basically means negative 1 divided by the slope.  

So if you slope was 3 perpendicular would be -1/3.  if the slope is a fraction you can just flip the fraction and make it negative.  so if the slope is  -2/3 a perpendicular slope would be 3/2, making a negative number negative makes it positive.

Now you start with 2x - 3y = 12.  To find the slope I like putting it in slope intercept form.  basically somethign that looks liek y = mx + b.  to do that just use algebra on what you have to get y by itself.  here is how I would do that.

2x - 3y = 12 first subtract 2x from both sides

-3y = 12 - 2x Now divide both sides by -3

y = 12/-3 - (2x)/3 Now simplify

y = -4 + 2/3 x Now rarrange to make it look like I said, basically you want the x first.

y = 2/3 x - 4

There, so the slope is 2/3.  A parallel line will have the same slope.

To make the equation of a line  you want one point and the slope.  Well we have that, the point is (-2,5) and the slope is 2/3.

To find a line you set up the point slope form.  that is y - y1 = m(x - x1) where m is the slope and x1 and y1 are the coordinates of the point you need.  I will plug all that in.

y - y1 = m(x - x1)

y - 5 = (2/3)(x - (-2))  Now solve

y - 5 = (2/3)x + 4/3

y = (2/3)x + 19/3

So that is the equation of a line parallel to 2x - 3y = 12 that passes through (-2, 5)

Step-by-step explanation:

8) Area of circle =

[tex]\pi {r}^{2} [/tex]

Radius = 1/2 of diameter (Diameter = 2x radius)

Radius = 1/2 × 10 in = 5 in.

Area of circle =

[tex]\pi {5}^{2} = 25\pi {in}^{2} [/tex]

11) Radius = 1/2 × 6m = 3m

Area of Circle =

[tex]\pi {3}^{2} = 9\pi {m}^{2} [/tex]

Note that I will leave both answers in terms of pi as I am not sure how you want to leave your answer as.

Answer:

area = πr×r

r = d/2

area = π (d/2)×(d/2)

so for problem 8,

area = pi×5×5 = 25π = 78.539 inches squared
