Answer: The answer is 15.
Step-by-step explanation: Given that there are a total of 60 students who signed up for hockey, where there were 3 boys for every 1 girl who signed up. We are to find the number of girls who signed up.
The ratio of the number of boys to the number of girls will be 3 : 1.
Let '3x' and 'x' be the number of boys and number of girls respectively who signed up.
Therefore, we have
Thus, the number of girls is 15.
Answer:
x ≈ 9.6
Step-by-step explanation:
Δ ABC is right with ∠ C = 90° ( angle between tangent and radius )
Using Pythagoras' identity in the right triangle
x² + 14² = 17²
x² + 196 = 289 ( subtract 196 from both sides )
x² = 93 ( take the square root of both sides )
x = ≈ 9.6 ( to the nearest tenth )
