  • Wat is die verskil tussen die hamburgers en die worsbroodjies se totale bedrae? ________________________________________________________

Tommie het besluit hy gaan vir Pappa help met die ponieritte. Hier is die baan wat hulle op die rugbyveld uitgemeet het.

  • Wat is die omtrek van die baan?

Die ponie sal 2 keer per rit om die baan gaan. Dit neem die ponie 5 minute om die 2 rondtes te voltooi en 'n bietjie te rus.

  • Watter afstand sal die ponie per rit aflê?
  • Hoeveel ritte kan die ponie in 1 uur voltooi?
  • Hulle gaan R5 per rit betaal. Hoeveel geld gaan hulle maak as 50 kinders op die ponie ry?
  • Wie kan bereken watter afstand die ponie dan altesaam afgelê het?
  • Hier is Tommie se plakkaat.

Bereken wat die pret vir sommige kinders gekos het.

  • Bonnie het 2 keer op die ponie gery en 1 keer op die springkasteel gespring.

Sy het ___________________________________________________ betaal.

  • Tommie het 3 keer met die windbuks geskiet en 1 keer op die ponie gery.

Hy het ___________________________________________________ betaal.

  • Terrie het 2 keer die balle gegooi en 1 kussinggeveg gehad.

Sy het ___________________________________________________ betaal.

  • Shane het alles 1 keer gedoen.

Hy het ___________________________________________________ betaal.

  • Robert het alles 2 keer gedoen.

Hy het ___________________________________________________ betaal.

  • Wat sal dit kos as jy alles 5 keer wil doen?

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.6: Dit is duidelik wanneer die leerder geldprobleme oplos wat totale en kleingeld in rand en sent behels, insluitend herleiding tussen rand en sent;

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder die gepaste simbole in berekeninge kan gebruik om probleme op te los;

Leeruitkomste 4: Die leerder is in staat om gepaste meeteenhede, instrumente en formules in 'n verskeidenheid kontekste te gebruik.

Assesseringstandaard 4.6: Dit is duidelik wanneer die leerder ondersoek (alleen en/of as ‘n lid van ‘n groep of span) en meet;

Leeruitkomste 5: Die leerder is in staat om data te versamel, op te som, voor te stel en krities te ontleed om gevolgtrekkings en voorspellings te maak en om toevallige variasie te interpreteer en te bepaal;

Assesseringstandaard 5.5: Dit is duidelik wanneer die leerder data wat in eenvoudige tabelle en lyste voorgestel word lees en interpreteer.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
