Mwanafunzi, weka swali linalokusumbua ili walimu na wazoefu wakusaidie

Kama uzi unavyojieleza, ningependa kujua wadudu waishio ardhini wanapataje hewa?

What is the composition of the soil?

 

[dan87]

Si kila mdudu anatumia hewa unayotumia wewe.... Kuna wengine Wanatumia Co2

Mfano?

Where are the mathematicians? Here is a brain teaser: Quantitative Reasoning.

A house wife forgot her bank account *PIN CODE* which is five digits number, but luckily she remembered some hints on how to recall this *PIN*.
Here are some of the clues
1) The *1st* digit is a square of the *2nd*
2) The sum of the *2nd* and *3rd* is 10
3) The *4th* is equal to the *2nd* plus *1*
4) The *3rd* and the *5th* makes *14*
5) The sum of all the digits is *30*

What is the *PIN CODE*?

let 1st digit=a
2nd=b
3rd=c
4th=d
5th=e
1.a=(b)2
2.b+c=10
3.d=b+1
4.e+c=14
5.a+b+c+d+e=30
=> (b)2+b+c+d+e=30 (a=(b)2)
=> (b)2+b+(10-b)+d+e=30 (b+c=10=>c=10-b)
=> (b)2+b+(10-b)+(b+1)+e=30 (d=b+1)
=> (b)2+b+(10-b)+(b+1)+(14-(10-b)=30(e+c=14=>e=14-c=>14-(10-b))
=> (b)2+b+10-b+b+1+14-10+b=30
=> (b)2+2b+15=30
=> (b)2+2b=30-15
=> (b)2+2b-15=0
=> (b)2+5b-3b-15=0
=> b(b+5)-3(b+5)+=0
=> (b+5) (b-3)=0
=> b+5=0 b-3=0
=> b= -5 b= 3
Value ya b itakuwa 3 kwa sababu kwenye pin yoyote hakuna negative digit
b = 3
Kwa ku-substitute equation za hapo juu tunapata

1st digit=9
2nd=3
3rd=7
4th=4
5th=7
Mkuu zawadi yangu please

[Ilankunda1234]

Electric device these are the device which operate due to the presence of electricity
These are powered by electricity, exampes are tv, radio machines and lumps.

Electronic device are the devices which contral the flow of electricity in the electric devices.
Examples are diodes, transistor and ic's
