10. LOGICAL SEQUENCE AND COMPARISON OF DECIMAL FRACTIONS

10.1 Work together with a friend and compare the results of the following athletes.

Put the athletes in order from the winner to the last place.

 Name Long Jump Position High Jump Position Alec 6,1 m ................... 1,63 m ................... Dimitri 4,85 m ................... 1,5 m ................... Owen 5,9 m ................... 1,11 m ................... Tembo 5,32 m ................... 1,6 m ................... Vera 5,09 m ................... 1,23 m ................... Cindy 4,9 m ................... 1,57 m ................... Sonia 6,04 m ................... 1,7 m ................... Gloria 5,21 m ................... 1,34 m ...................

10.2 a) Find the following statistics of five of your class mates and complete the table:

 Name Height Mass 1. .................................................. .................... .................... 2. .................................................. .................... .................... 3. .................................................. .................... .................... 4. .................................................. .................... .................... 5. .................................................. .................... ....................

b) Arrange names of your friends from the shortest to the tallest:

1. ...............................................................

2. ...............................................................

3. ...............................................................

4. ...............................................................

5. ...............................................................

c) Now arrange names of your friends from the heaviest to the lightest:

1. ...............................................................

2. ...............................................................

3. ...............................................................

4. ...............................................................

5. ...............................................................

10.3 Fill in:<;>or = :

a) 0,63 …… 0,7

b) 0,4 …… 0,39

c) 32,068 …… 32,102

d) 1,27 …… 1,270

e) 0,007 …… 0,07

f) 4,44 …… 4,044

## Assessment

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.

Assessment Standard 1.3: We know this when the learner recognises, classifies and presents the following numbers in order to describe and compare them:

1.3.2 decimal (to at least three decimal places), fractions and percentages;

Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.

Assessment Standard 2.3: We know this when the learner represents and uses relationships between variables in a variety of ways using:

2.3.3 tables.

Learning Outcome 5: The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.

Assessment Standard 5.7: We know this when the learner identifies the largest and smallest scores in a data set and determines the difference between them in order to determine the spread of the data (range).

can someone help me with some logarithmic and exponential equations.
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

hello
Sherica
im all ears I need to learn
Sherica
right! what he said ⤴⤴⤴
Tamia
what is a good calculator for all algebra; would a Casio fx 260 work with all algebra equations? please name the cheapest, thanks.
a perfect square v²+2v+_
kkk nice
algebra 2 Inequalities:If equation 2 = 0 it is an open set?
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

No. 7x -4y is simplified from 4x + (3y + 3x) -7y
is it 3×y ?
J, combine like terms 7x-4y
im not good at math so would this help me
yes
Asali
I'm not good at math so would you help me
Samantha
what is the problem that i will help you to self with?
Asali
how do you translate this in Algebraic Expressions
Need to simplify the expresin. 3/7 (x+y)-1/7 (x-1)=
. After 3 months on a diet, Lisa had lost 12% of her original weight. She lost 21 pounds. What was Lisa's original weight?
what's the easiest and fastest way to the synthesize AgNP?

types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
preparation of nanomaterial
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
what is system testing
what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
how did you get the value of 2000N.What calculations are needed to arrive at it
