Answer:
32.92
Step-by-step explanation:
well you just do base times height
the height is 3.5
the area of the base is 3 * pi which is 9.42 if you round pi to 3.14
so 3.5*9.42= 32.92
Left side angle = 180-150-12 = 18 degrees
10 / sin 12 = c / sin 18
c = 10 * sin 18 / sin 12
c = 14.9 cm to nearest tenth
The answer is either a gram or kilogram
So prpbility is (desired outcomes)/(total possible outcomes)
there are 11 letter so 11 total outcomes
so chosing a B or an I so find how many total
2 B nd 2 I's
2+2=4
so 4/11 is the probablity
The first question:
3X+Y=-1
Y=-3X-1 Y=-1/2X-7/2
-3X-1=-1/2X-7/2
-2.5X=-2.5
x=1
So the answer should be option B.
The last question:
Same thing ,
-1/2X-1=-3X+4
2.5X=5
X=2
So the answer is option B.
Those are your answers.
