Cov tub ntxhais kawm nkag siab tias a piv feem ntau yog siv los piav txog kev sib raug zoo ntawm tus nqi ntawm ib qho. kom muaj nuj nqis thiab tus nqi ntawm lwm qhov ntau npaum li nyob rau hauv cov ntaub ntawv ntawm kev sib tov lossis tus nqi tas li. ? Cov tub ntxhais kawm nkag siab tias a ratio rooj yog a lub rooj sib npaug sib npaug . Cov tub ntxhais kawm siv piv rooj daws.
Ua raws li qhov no hauv kev xav, dab tsi yog lub rooj sib piv?
A ratio rooj yog ib daim ntawv teev npe sib npaug (tus nqi sib npaug) piv uas pab peb nkag siab txog kev sib raug zoo ntawm cov piv thiab cov lej. Cov nqi, zoo li koj lub plawv dhia, yog hom tshwj xeeb piv , qhov twg ob tus lej sib piv muaj qhov sib txawv.
Tom qab ntawd, lo lus nug yog, koj ua li cas kom yooj yim qhov piv? Rau ua kom yooj yim a piv , pib los ntawm kev faib tawm ob tus lej hauv qhov piv . Tom qab ntawd, nrhiav qhov tseem ceeb tshaj plaws, uas yog qhov tseem ceeb tshaj plaws uas ob tus lej hauv piv qhia. Thaum kawg, faib ob tus lej los ntawm qhov tseem ceeb tshaj plaws kom tau txais yooj yim piv.
Ib sab saum toj no, koj daws qhov piv txwv li cas?
Txhawm rau siv proportions los daws qhov teeb meem ntawm lo lus, peb yuav tsum ua raws li cov kauj ruam no:
- Txheeb xyuas qhov paub piv thiab qhov tsis paub qhov piv.
- Teeb tsa qhov kev faib ua feem.
- Hla-multiply thiab daws.
- Xyuas cov lus teb los ntawm kev ntsaws qhov tshwm sim rau hauv qhov tsis paub qhov piv.
Cov piv txwv ntawm cov piv txwv yog dab tsi?
Hauv lej, a piv qhia tias pes tsawg zaus ib tus lej muaj lwm tus. Rau piv txwv , yog hais tias muaj yim txiv kab ntxwv thiab rau lemons nyob rau hauv ib lub tais ntawm txiv hmab txiv ntoo, ces tus piv ntawm txiv kab ntxwv rau txiv qaub yog yim rau rau (uas yog, 8∶6, uas yog sib npaug rau piv 4∶3).

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib npaug sib npaug flattened sacs nroj tsuag nkaus xwb?
Lub Sijhawm: Chloroplast Txhais: Ze li stacked, flattened sacs (tsuas yog cov nroj tsuag). Muaj Chlorophyll, cov xim ntsuab uas cuam tshuam lub zog ntawm lub hnub ci thiab muab cov nroj tsuag lawv cov xim ntsuab Lub sij hawm: Ribosome Txhais: Qhov chaw ntawm cov protein synthesis
Kev daws qhov sib npaug sib npaug yog dab tsi?
A rational equation Ib qho kev sib npaug uas muaj tsawg kawg yog ib qho kev qhia rational. yog ib qho kev sib npaug uas muaj tsawg kawg yog ib qho kev qhia rational. Kev daws qhov sib npaug sib npaug los ntawm kev tshem cov feem ntau los ntawm kev sib faib ob sab ntawm qhov sib npaug los ntawm qhov tsawg tshaj plaws denominator (LCD). Piv txwv 1: daws: 5x− 13 = 1x 5 x − 1 3 = 1x
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
