Hello there!
21 * 3.14 = 65.94
Thus,
The circumstances of the swimming pool is 65.94
<span>42=-2d+6
Here, to find d, you need to separate it on one side.
First, subtract 6 from both sides.
42-6 = -2d + 6 - 6
36 = -2d
Now divide both sides by -2.
36/-2 = -2/-2d
-18 = d
The answer to this problem is -18, or d = -18.</span>
Yes, because you need to remember and/or list out your square roots no matter what.
<span>There are 56 possible combinations when drawing two chips. Remember that you cannot draw two of the same chips from the bag, so 11, 22, 33, 44, 55, 66, 77, and 88 are not possible. Therefore, 20 of 56 combinations are divisible by 3, or approximately 36 percent.
