Subtract 3 from both sides
(z = -9 - 3)
Simplify -9 - 3 to -12
z = -12
3 + -12 = -9 so this is true.
We know that the diameter of the inner circle (d) and the side of a regular octagon (s) are tied by the formula:
d = (1 +√2) × s
The inverse formula is:
s = d / <span>(1 +√2)
Plugging in numbers:
s = 7 (1 + </span>√2)
= 2.9 ft
Therefore the correct answer is A) <span>2.9 feet</span>
Answer:
16/33
Step-by-step explanation:
12C4(total possible outcomes)=495
Since there are 6 married couples there must be 6*[2C2×10C2]=270
must subtracted 15 since when there are 2 couples in a group would have doubled 270-15=255
the no of groupings with no married couples 495-255 =240
probability=no of favourable outcomes /no of possible outcome
probability=240/495= 16/33
D. Inequality
An expression would just contain simple arithmetic without any symbols relating two things to another.
An equation must contain an equals sign.
A fraction will have a bar representing division.
An inequality contains a sign representing a comparison of magnitude, in this question less than <.
Hope this helps!!
Answer:
(-6+y)-3y=28
-2y-6=28
-2y=34
