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)

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

ReplyDeleteWell, it only says #9, nothing else, so... you tell me.

ReplyDeleteDear A & ASTWTBABDWABNLATOA,

DeleteFor 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?

MRC

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

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

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

ReplyDeleteThe 'g' is for grams, not gallons.

DeleteI 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:

mrhuestonscience.weebly.com/uploads/5/6/.../conversion_factor_reference_sheet.doc

I am confused, for the hand in what page is #9 on. I confused.

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

DeleteFor the Hand-in, use the info in #9 to answer the new questions that I posed a) and b)...

Gotsk it now?

Yes I do gotsk it now thank you.

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

ReplyDeleteDear LOLLO,

DeleteYou 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.

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?

ReplyDeleteI need help with problem 29

ReplyDeleteYou 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.

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

ReplyDeleteDo you know anything about her current speed. You should state what you know (especially if you want any help).

DeleteHave 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?

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.

DeleteSo, 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?

DeleteWhat 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.

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

DeletePerhaps you could try googling "converting yards to meters"

https://www.google.com/search?q=converting+yards+to+meters&oq=converting+yards+to+meters&aqs=chrome..69i57j69i64j0l4.8720j0j1&sourceid=chrome&ie=UTF-8

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.

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

DeleteThe 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

When is the correction for the test and quiz due for b-day

ReplyDeleteAs mentioned in the email to you and your parents...

DeleteOn B-day... tomorrow... Tuesday... Martes.
