1/2=4/8. 3 and 4/8+ 3 and 3/8 is 6 and 7/8.
Because the triangles are similar the ratio of all the sides would be the same. So you need to find the ratio of the common sides and then use that ratio to find the unkown side.
In this picture sides FG = 52, FV would be the same side and is 24.
Dividing 24/52 = 0.461, so the unkown side WV would be 0.444 of it's common side HG.
HG = 39
39 * 0.461= 18.
The answer is C. 18
Answer:
X=25
Y=25
Z=115
Step-by-step explanation:
To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
Answer would be D You can have a rational discriminant for an irrational root, but you can also have rational discriminant for a rational root. So C is partially correct.
<span>All prime discriminants will result in an irrational root, but not all irrational roots have prime discriminants </span>
