50 > = 15x....divide both sides by 15
50/15 > = x
10/3 > = x or x < = 10/3
so the correct solution set is : { x | x < = 10/3}...its the 2nd one
ANSWER
(C)38.16
EXPLANATION
The acute angle given in the right triangle is 27°.
The side length adjacent to the 27° angle is 34 units.
The side length we want to find is x units, which is the hypotenuse of the right triangle.
We use the cosine ratio to obtain:


Solve for x,


to the nearest hundredth.
Use all the top to multiply by it
Then divide by the buttom.
12 girls - 48%
48% ÷ 12 = 0.25
100% - 48% = 52%
1% - 0.25
52 % = 0.25 × 52 = 13 boys
Answer:
The answer is below
Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.
The distance between two points on the coordinate plane is given as:

In triangle STU:

|QR| / |TU| = 4/2 = 2
|PR| / |SU| = 6/3 = 2
|PQ| / |ST| = 2√13 / √13 = 2
Hence:
|QR| / |TU| = |PR| / |SU| = |PQ| / |ST|
Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.
