4×2=8 so n=2 and 8+12=20 so ?=12
The correct answer is C. Commutative Property
Answer:
4 i think
Step-by-step explanation:
1) mesure of an arc= R.Ф, where R is the radius & Ф the angle <span>IN RADIAN
32</span>°===>8π/45 OR 0.5585, So mes of Arc CD = 6x0.5585 = 3.35 cm
2) DAC = 31° & CAD =27° , these 2 angles being adjacent I can write that
Angle(DAC +CAB=DCB) ==>Angle DCB =(31°+27°=58°)
To remember that any vertex of an angle on the circles, its sides intercept an arc which mesure is twice the angle,
Hence since mes Angle DCB=58°, that means the ARC intercepted, namely DB has a length of 2x 58 = 116°
The answer is 3/5 simplified.
Reasoning:
There are 6 solid white and solid black marbles combined.
There are total of 10 marbles.
Of the 10 marbles, you are 6/10 times likely to pull one of the solid black or white marbles.
Simplify 6/10 by dividing it by a number they both share (2) to get the answer of 3/5.
