So, what is given is the time, and the distance. the distance is equal to the time multiplied by the minute.
time =t, and distance =d.
how to get from t to d is
T divided by 2 multiplied by three equals to D, or T/2 x 3=d.
Your answer would be C. 8
Step-by-step explanation:
7(3x - 1) - (x + 5) = -52
21x - 7 - x - 5 = -52
20x = -52 + 12
20x = -40
x = -2
Answer:
Step-by-step explanation:
If arccos (√3 / 2) = β, then cos β = adjacent side / hypotenuse = √3 / 2. This tells us immediately that the adjacent side length is √3 and the hypotenuse is 2. Via the Pythagorean Theorem, we know that the third side is 1.
This information rules out the 1st and 3rd answer choices.
Because cos 30° = adj / hyp = √3 / 2, we can conclude that the correct answer is the 4th one: 30°, 60°, 90°
