Answer:
Let x = the third side
In a triangle, the sum of any 2 sides must be larger than the third side.
I believe this is called the triangle inequality theorem.
We can construct 3 inequalities to obtain the range of values for the third side.
(Inequality #1) 12 + 4 > x
16 > x
(Inequality#2) 12 + x > 4
x > -8 (we can discard this ... we know all sides will be positive)
(Inequality #3) 4 + x > 12
x > 8
So when we combine these together,
8 < x < 16
X (the third side) must be a number between 8 and 16. but not including 8 and 16
The answer is B.
In order to add the two values together, you must find the least common multiple for the denominators. The denominators are 8 and 4, and the least common multiple of 8 and 4 is 8. Because you have to multiply 4 by 2 to get 8, you must also multiply 3 by 2 to get 6. This will give you 6/8.
If you miss 9 questions, the how many did you get right?
85 - 9 = 76
So now you got 76 out of 85 correct or 76/85...
Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...
76 divided by 85 which equals...
.8941
Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)
.8941 x 100 = 89.41% Round to nearest one percent...
89%
