DIE VERHAAL VAN VOEDSEL

Die verhaal van voedsel

Voedsel speel ‘n baie belangrike rol in ons daaglikse lewe. Ons eet om te groei, gesond te wees en aan die lewe te bly. Daar is ook mense wie se hele lewe om kos draai – hulle lewe net om te eet!

Voordat ons kyk hoe voedsel in die 21 ste eeu geproduseer word, is dit belangrik om te

weet hoe ons voorvaders hulle borde van dag tot dag met kos gevul het.

Honderde jare gelede het die kos wat mense geëet het, baie verskil van dit wat ons vandag geniet. Eers was mense .........................................-versamelaars wat van plek tot plek agter wild aangetrek het om sodoende hulle kos te bekom. Hulle het in tydelike skuilings gebly en wanneer die wild min geraak het, verder getrek. Die vleis is aangevul met .......................................... wat hul gepluk het en .................................. wat hul uitgegrawe het. Drinkwater is verkry deur van reën of dou op te vang of uit riviere en damme te skep.

Die jagters het later hulle eie troppe skape, beeste en bokke begin versamel en makgemaak en sodoende .............................. geword wat met hul eie vee agter beter weivelde aangetrek het. Nou het hul melk en ...................................... gehad en was dit nie meer nodig om te jag nie.

Die veewagters het ............................................. geword wat verkies het om op een plek te bly en hul koring te verbou van die saad van wilde grasse. Die mense het in klein groepe naby vars water gebly en gou is die ................................... ontwerp om die boere te help met die bewerking van die grond. Hulle het ook beter metodes ontwikkel om water tot by hul landerye te kry (besproeiing). Van die gemeenskappe het groter geword en daar is geëksperimenteer met verskillende landbougewasse, soos mielies, sorghum, pampoene, botterskorsies, wilde waatlemoene, ens.

Deel van die oeste is gebêre om kos vir die hele jaar te hê terwyl ander weer na naburige dorpies geneem is om dit te ........................... vir ander kos of produkte.

Namate tegnologie ontwikkel het, het die boerderymetodes ook baie verander. Destyds se houtploeë is vervang met ysterploeë en word nie meer met die hand gestoot nie maar wel met lugverkoelde trekkers wat tot twintig ploeë op een slag kan trek.

Wayne and Dennis like to ride the bike path from Riverside Park to the beach. Dennis’s speed is seven miles per hour faster than Wayne’s speed, so it takes Wayne 2 hours to ride to the beach while it takes Dennis 1.5 hours for the ride. Find the speed of both bikers.

from theory: distance [miles] = speed [mph] × time [hours] info #1 speed_Dennis × 1.5 = speed_Wayne × 2 => speed_Wayne = 0.75 × speed_Dennis (i) info #2 speed_Dennis = speed_Wayne + 7 [mph] (ii) use (i) in (ii) => [...] speed_Dennis = 28 mph speed_Wayne = 21 mph
George
Let W be Wayne's speed in miles per hour and D be Dennis's speed in miles per hour. We know that W + 7 = D and W * 2 = D * 1.5. Substituting the first equation into the second: W * 2 = (W + 7) * 1.5 W * 2 = W * 1.5 + 7 * 1.5 0.5 * W = 7 * 1.5 W = 7 * 3 or 21 W is 21 D = W + 7 D = 21 + 7 D = 28

Shakir works at a computer store. His weekly pay will be either a fixed amount, $925, or $500 plus 12% of his total sales. How much should his total sales be for his variable pay option to exceed the fixed amount of $925.
mahnoor Reply
I'm guessing, but it's somewhere around $4335.00 I think
Lewis
12% of sales will need to exceed 925 - 500, or 425 to exceed fixed amount option. What amount of sales does that equal? 425 ÷ (12÷100) = 3541.67. So the answer is sales greater than 3541.67. Check: Sales = 3542 Commission 12%=425.04 Pay = 500 + 425.04 = 925.04. 925.04 > 925.00
