Answer:
2 5/6
Step-by-step explanation:
WE CHANGE 3 1/2 INTO IMPROPER FRACTION WHICH IS 7/2
7/2-2/3=2 5/6
Answer:
arc AB = 70°
arc BC = 110°
arc ABC = 180°
arc CDB = 250°
Step-by-step explanation:
Since these angles are not inscribed, but are at the center point of the circle, the angles and arcs will be the same measure.
Solve for arc AB:
Angle AFB = 70°, so arc AB = 70°
Solve for arc BC:
Angle AFC is a straight angle so it is 180°. To find angle BFC, subtract angle AFB from 180°.
180 - 70 = 110°
Since angle BFC = 110°, arc BC = 110°
Solve for arc ABC:
Add arc AB and arc BC together.
70° + 110° = 180°
arc ABC = 180°
Solve for arc CDB:
There are 360° in a cirlce. To find arc CDB, subtract arc BC from 360°.
360° - 110° = 250°
arc CDB = 250°
Answer:
25%
Step-by-step explanation:
% Change = Change ÷ Original × 100
% Change = 19 ÷ 76 × 100
% Change = .25 × 100
% Change = 25

C. 22 M
Step-by-step explanation:
Answer:
x = 18
Step-by-step explanation:
When two parallel lines are intersected by a transversal, then same-side exterior angles are supplementary, meaning their angle measures add up 180 degrees. Applying this knowledge here, one can state that;
( 6x - 3 ) + 75 = 180
Simplify,
6x - 3 + 75 = 180
6x + 72 = 180
Inverse operations,
6x + 72 = 180
-72 -72
6x = 108
/6 /6
x = 18
