Inhoud

Aktiwiteit: om deelbaarheidsreëls te herken, te beskryf en te gebruik [lu 1.12.1]

Net soos by vermenigvuldiging, is daar sekere reëls vir deling deur veelvoude van 10 wat jou in staat stel om antwoorde in ‘n japtrap te bereken – sonder om potlood en papier te gebruik! Vir die volgende aktiwiteite moet julle in groepe van drie verdeel.

1. Kyk of julle reëls kan formuleer vir die volgende:

2. Deling deur 10: __________________________________________________

_______________________________________________________________

_______________________________________________________________

3. Deling deur 100: _________________________________________________

_______________________________________________________________

_______________________________________________________________

4. Deling deur 1 000: ________________________________________________

_______________________________________________________________

_______________________________________________________________

5. Deling deur 10 000: _______________________________________________

_______________________________________________________________

_______________________________________________________________

6. Vergelyk nou jul antwoorde met die res van die klas s’n!

7. Hoe vinnig kan jy nou die antwoorde van die volgende neerskryf SONDER om ’n sakrekenaar te gebruik?

GETAL ÷ 10 000 ÷ 1 000 ÷ 100 ÷ 10

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 1.12: Dit is duidelik wanneer die leerder herken, beskryf en gebruik:

1.12.1: deelbaarheidsreëls vir 2, 5, 10, 100 en 1 000;

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
