Answer:
a=-36
Step-by-step explanation:
1/6(a+12)=-4
1) Distribute <u>1/6</u> to a and 12:
1/6a+2=-4
2) Subtract 2 from both sides:
1/6a=-6
3) Multiply both sides by the reciprocal of 1/6: (6/1)
a=-36

The answer is 45°
By determining the angles of triangle ACB (A=30°, B=45°, C=105° (total of 180°)) and knowing that angle 1 correlates to angle 4 ((1)°=(4)°), we can find angle 1, which is 45°, equal to angle 4.
Answer:
Suppose the fraction of blue balls at any given state n is 
. At the start of the process we have: 
=1.
Now consider the situation after having drawn n times.
The current fraction of blue balls is , the number of blue balls is therefore 10.
We either draw a red ball, with probability 1−. and the number of red balls, blue balls stay the same (we swap red for red):
(red)=
or we draw a blue ball, with probability and we obtain 10−1 blue balls on a total of 10 balls, thus:
(blue) = (10− 1)/10
The total probability of (fraction of) blue balls after this n'th draw is therefore:
=(red)(1−)+(blue)
which can be simplified to:
=0.9
which leads to:
fn=0.9
At the end of the 10'th draw the fraction of blue balls is equal to:
= 
≈ 0.348678
Answer:
divide 150 by 12 ( because there are 12 inches in one foot) and your answer would be 12.5 feet.
