Answer:

12 minutes 40 seconds

Step-by-step explanation:

One keychain, 1 minutes 35 second = 1*60 + 35 = 95 seconds

8 keychains, 95 * 8 = 760 seconds = 760/60 = 12.66667 minutes

= 12 minutes 0.66667*60 seconds

= 12 minutes 40 seconds

Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
algol13
Answers:
x = 24
y = 8√3
Explanation:

1) Since, the given triangle is a right triangle, and you have both an angle and the hypotenuse length, you can use some trigonometric ratios to find the variables.

2) The variables given represent:

x: adjacent-leg to angle 30°
y: opposite length to angle 30°

3) sine ratio:

sin 30° = opposite-leg / hypotenuse = y / (16√3)

⇒ y = 16√3 sin 30° = 16√3 × (1/2) = 8√3

4) cosine ratio

cos 30° = adjacent-leg / hypotenuse = x / (16√3)

⇒ x = 16√3 cos 30° = 16√3 (√3 / 2) = 16 × 3 / 2 = 24
