suppose that eight terms of a wire are wrapped around a pipe with a length of 60 in and a circumference of 4 inches so that the
EastWind [94]
The length of the wire is the length of the hypotenuse of a triangle with one leg 60 inches and the other leg 8*4 in = 32 inches.

√(60² +32²) = √4624 = 68

The wire is 68 inches long.

_____
Consider what happens if you wrap a paper triangle of those dimensions around the pipe. The hypotenuse edge traces the path of the wire.

PLEASE HELP DUE SOON! IM SO CONFUSED!!!

The first step that we need to take before attempting to solve a problem is to understand what the problem is asking us to do and what is given to us to help accomplish that goal.  Looking at the problem statement they are asking for us to determine the value of the unknown variable h.  We are given one angle along with two sides.

Now that we have completed that step, we can move onto understanding what needs to be done to solve for the unknown.  We know that the best option is to use some trigonometry to help us determine the other side. Using Soh | Cah | Toa we are able to determine that we have the opposite side (h) and the hypotenuse (15.6 cm).

<u>Trigonometric functions</u>

  • sin(\theta) = \frac{opposite}{hypotenuse}
  • cos(\theta) = \frac{adjacent}{hypotenuse}
  • tan(\theta) = \frac{opposite}{adjacent}

<u>Plug in the values</u>

  • sin(\theta) = \frac{opposite}{hypotenuse}
  • sin(36) = \frac{h}{15.6\ cm}

We know have an expression which contains everything that we need to determine the value of the unknown.  To help isolate h we need to multiply both sides by 15.6 cm which will isolate h.  After that we need to simplify the expression so we can get the value of h.

<u>Multiply both sides by 15.6 cm</u>

  • sin(36) * 15.6\ cm = \frac{h}{15.6\ cm}  * 15.6\ cm
  • sin(36) * 15.6\ cm = h

<u>Simplify the expression</u>

  • 0.5878 * 15.6\ cm = h
  • 9.169 = h

After simplifying the expression, we are able to eliminate options A and C because they state that h is equal to 8.4 cm.  We also know that with the given dimensions we would be able to create two triangles. Therefore, the option that best incapsulates the correct answer would be option B - 9.2, two possible triangles.

It's candy time! Suppose 5 friends go out candy collecting. Starting out, Ms. Gleason gave each of them 12 pieces of candy. Then
sdas [7]

Answer:

6 hours

Step-by-step explanation:

First, since they all collected 510, you divide 510 by 5, to figure out how much each person got.

You then know that each of them got 102 candies, so now, you subtract 12 from from 102, since the teacher gave them that much in the beginning.

You're left with 90, so last step is to divide 90 by 15, since they collect 15 every hour, which you get left with 6. Meaning they collected candies for 6 hours
