hw #2-6B BIG PHAT ONEs Rule!

hw #2-6B
Watch the "2-6 Converting Rates 1" video
pg 119-120 #1-8 ALL, #9-33 ODD

HAND-IN !!
#9 - Use the data in #9 to calculate the following:
a) Trisha's speed in miles per hour
b) Jason's speed in feet per second
Hint (you can use more than just two conversion factors... for example, you could convert km to miles and then miles to feet in Jason's problem, in addition to converting hours to seconds)

  1. Is #9 all the hand in we have to do? I already did the normal hw

    1. Dear A & ASTWTBABDWABNLATOA,

      For the regular homework, do #9 as stated.

      For the HAND IN assignment... I don't want you to do the same #9... I want you to USE THE INFO IN #9 to answer the questions I am posing in the extra a) & b) questions.

      Gotsk it?

  3. on question one which i the better buy. 6 b for 3.29 or 8 b for 4.15 I am confused. Would we just divide or is there a certain method you want us to use. I looked for a video and there were just videos on conversion. Thanks

  4. This is just like the "shirt" problem we did in class!... JUST DIVIDE. And compare the UNIT RATES!!

  5. On problem 33, the question was whether 75 gallons or 5 ounces was bigger and I'm not sure how to work out this problem.

    1. The 'g' is for grams, not gallons.

      I do not expect you to know conversion factors from grams to ounces, etc. You can find them on the web or use a reference sheet... such as:

    1. Dear Confused... #9 on page 119 comes in two flavors...do the problen as it reads for your regular homework.

    I am confused on problem 3 where you have to find which is greater, 12m or 3yd.

    1. Dear LOLLO,
      You should be able to convert meters to yards or vice versa, and make the comparison. As a human being (although based on your identity, I'm not so sure) you should also be familiar with the fact that a meter stick is about the same length as a yard stick. Therefore, you should realize that 12m must be greater than 3yd without the need for any math.

  8. In "a" of the hand in problems we have to convert kilometers to miles at some point (right?) and google says that 1 kilometer is equal to 0.621371 miles so my question is can we round? and if so up to what place?

  9. I need help with problem 29

    1. You need to state the problem if you want me to address it. And you should also try to articulate a first step of some kind.

    I need help with problem 9a which asks what is Trisha's average speed in miles per hour.

    ReplyDelete
    Replies
    1. Do you know anything about her current speed. You should state what you know (especially if you want any help).

      Have you watched the video on converting rates, or looked at the sample problems in the text book in section 2-6.

      In other words, are you being resourceful?

      Delete
    2. You have to divide the kilometers by the time that it took them to run the distance, then compare the answers and the person who's quotient was the lowest had the fastest average speed.

      Delete
    3. So, if you had each person's time in the same Unit of Measure (UOM), whether it be km/sec or feet/min or whatever, you would be able to make the comparison, right?

    What conversion rates do I need to figure out 9 yards into meters inches into meters doesn't sound right to me but I could be wrong.

    1. I said you can find any conversion you need on a reference sheet or on the web.

      Perhaps you could try googling "converting yards to meters"

    I am having trouble with problem 21. The problem is 89cm; in. I watched all the videos but they were working down in units of measure and I don't know how to work up like this.

    ReplyDelete

    1. This is handled just like any other unit conversion... I'm not sure what you mean by up vs down.

      The conversion factor for cm to inches is 2.54cm per 1 inch.

      Take a look at Problem 3 on pg 117.

      You should use the conversion factor as 1 inch OVER 2.54cm, because you need the unit of cm to divide out.

      (notice in Problem 3 how the "ft" divide out)

      89cm * (1 inch / 2.54 cm)
      The unit of cm's will "divide out" leaving you with
      89 * 1 inch OVER 2.54
      Simply use a calculator to divide 89/2.54 to obtain your answer of 35.04 inches are equivalent to 89cm
