Answer:
2 rides per hour
Step-by-step explanation:
she rode 18 rides in 9 hours
therefore rate at which she rides = 18/9 = 2
Answer:
π/4, 3π/4
Step-by-step explanation:
3tanx = 3
tanx = 1
Basic angle: π/4
x = π/4
x = π + π/4 = 3π/4
First, let's let's evaluate the numerator and denominator separately.
The numerator: (-2)^2(3)(4) - (-1) = 48 + 1 = 49
The denominator: (-2)^2 = 4
Now that the numerator and denominator are simplified, let's take the square root of 49/4
sqrt(49/4) = 3.5
This question is a bit confusing, but i would say that the correct answer is f. The sum of the digits would be 3, which isn't divisible by 9.
∠KLN and ∠MLI make up a pair of vertical angles.
Vertical angles share a vertex and are the opposite angles formed by intersecting lines. They are also congruent, but just because two angles are congruent doesn't mean they are vertical. That's why ∠KLN and ∠JIG are NOT vertical, for instance.
