Thawj sib xyaw cov duab yog ib qho kev sib txuas ntawm ib lub duab plaub prism thiab a pyramid . Yuav nrhiav tau ntim ntawm tag nrho cov duab koj pom cov ntim ntawm txhua tus neeg cov duab thiab ntxiv lawv ua ke. Qhov thib ob daim duab muaj ib lub tog raj kheej thiab lub hemisphere.
Hauv qhov no, qhov ntim ntawm cov duab sib xyaw yog dab tsi?
Composite Figures Hauv Geometry: Hauv geometry, yog tias muab geometrical daim duab yog tsim los ntawm ob lossis ntau dua geometrical cov duab , peb npe a composite daim duab . Thaum a composite daim duab yog peb-dimensional geometrical daim duab , nws muaj a ntim uas yog sib npaug ntawm qhov chaw uas nyob hauv lub daim duab.
Tsis tas li ntawd, dab tsi yog daim duab sib xyaw? A daim duab (los yog puab ) uas tuaj yeem muab faib ua ntau tshaj ib qho ntawm qhov pib cov duab hais tias yog ib composite daim duab (los yog puab ). Piv txwv li, daim duab ABCD is a composite daim duab raws li nws muaj ob qho yooj yim cov duab . Ntawd yog, a daim duab yog tsim los ntawm ib daim duab plaub thiab daim duab peb sab raws li qhia hauv qab no.
Qhov thib ob, tus qauv rau ntim yog dab tsi?
Xam Volume Tus formula kom pom lub ntim muab cov ntev los ntawm qhov dav los ntawm qhov siab . Xov xwm zoo rau a kub yog tias qhov ntsuas ntawm txhua qhov ntev yog tib yam. Yog li ntawd, koj yuav multiply ntev ntawm ib sab peb zaug. Qhov no tshwm sim hauv cov qauv: Volume = sab * sab * sab.
Yuav ua li cas koj pom qhov ntim ntawm lub pyramid?
Rau xam qhov ntim ntawm a pyramid nrog lub hauv paus rectangular, nrhiav qhov ntev thiab qhov dav ntawm lub hauv paus, ces ntau tus lej ua ke rau txiav txim thaj tsam ntawm lub hauv paus. Tom ntej no, muab cov cheeb tsam ntawm lub hauv paus los ntawm qhov siab ntawm qhov pyramid . Siv qhov tshwm sim thiab faib nws los ntawm 3 mus rau xam tus pyramid lub ntim !

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Puas yog Krypton yog ib qho khoom sib xyaw lossis sib xyaw?
Krypton (Kr), cov khoom siv tshuaj, cov pa roj tsawg ntawm Pawg 18 (noble gases) ntawm lub sij hawm lub sij hawm, uas tsim cov tshuaj muaj pes tsawg leeg. Txog peb zaug hnyav dua huab cua, krypton tsis muaj xim, tsis muaj ntxhiab, tsis qab, thiab monatomic
Yuav ua li cas koj pom qhov sib npaug ntawm qhov nqus ntawm qhov nqus?
X = [Fe(SCN)2+] thiab yuav tsum tau txiav txim los ntawm tus qauv nkhaus. Tom qab ntawd koj tuaj yeem xam qhov sib npaug tas li, Keq, siv qhov sib npaug sib npaug. Tus qauv nkhaus yog ib zajlus ntawm Absorbance piv [Fe(SCN)2+] (Daim duab 8.1). Nws tuaj yeem siv los muab peb cov concentration ntawm cov tshuaj thaum muab cov absorbance
