Answer:

Step-by-step explanation:

6 11/12-(24 1/6+3 2/3)

=(6×12+11)/12-[(24×6+1)/6+(3×3+2)/3]

=(72+11)/12-[(144+1)/6+(9+2)/3]

=83/12-[145/6+11/3]

=83/12-[(145+2×11)/6]

=83/12-[167/6]

=83/12-334/12

=(83-334)/12

=-251/12

=-20 11/12

The following figure is not drawn to scale.
erik [133]

Answer:

The triangle angle rule says that all of the angles in a triangle will add up to equal 180. So to find x we subtract the given angles ( 45 and 60 in this case) from 180.

x = 180-60-45

180-60-45=75

so x = 75

To find y we know that angle x and and y are angles formed on a straight line that are split up by a triangle segment. These angles are called supplementary angles which add up to equal 180.

So knowing that angle x = 75 we can find angle y by subtracting 75 from 180

180-75=105 so y = 105

Another way we could solve for y is the exterior triangle rule

This rule states that an exterior angle of a triangle is equal to the two opposite interior angles

so y = 45 + 65

45 + 65=105

so y = 105

What part of the circumference is an arc whose measure is 30°?
Radda [10]
Circumference of a circle:
C = 2 r π;
Length of an arc:
L = r π α / 180°
L = r π · 30° / 180° = r π /6
r π /6   :   2 r π = 1/6 : 2 = 1/12
Answer: A ) 1/12

Solve the Absolute Value Equation. <br><br> |9x+1| = 46
Sedaia [141]
X = 5 (you can set it up as a regular equation)
9x + 1= 46
9x = 45 (subtracted 1 from both sides)
x = 5 (divided 45 by 9)
hope this helps :)
