A package of 4 pairs of insulated gloves costs $21.56. What is the unit price of the pairs of gloves?
SOVA2 [1]

Answer:

Your answer is $5.39.

Step-by-step explanation:

There are 4 pairs of gloves. The unit price is only for a single pair of gloves, so divide the total cost by the pairs of gloves to get your answer: 21.56 ÷ 4 = 5.39. (Also, since we are talking about money, there would be a dollar sign next to 5.39: $5.39)

The boat shown in the accompanying figure is 3 miles from both lighthouses and the angle between the line of sight is 20 degrees
muminat

Answer: 1.04\ miles

Step-by-step explanation:

Observe the figure attached.

You can identify that the triangle formed is Isosceles, because it has  two equal sides.

Notice that you can divide it into two equal right triangles. Now the angle 20° is divided by 2 and you get two equal angles that measure 10°.

To find "x", apply the Trigonometric Identity sin\alpha=\frac{opposite}{hypotenuse}:

 sin(10\°)=\frac{x}{3}\\\\x=3*sin(10\°)\\\\x=0.52\ miles

Then, the distance between the lighthouses can be represented with:

d=2x

Substituting the value of "x" into this equation, you get:

d=2(0.52\ miles)\\\\d=1.04\ miles
