                                           bài giải

lượng nước có trong 30kg nấm tươi là:

        30.9/10=27(kg)

khối lượng nấm khi ko kể nước có trong 30kg nấm là:

      30-27=3(kg)

khối lượng đó chiếm:

    1-2/5=3/5(khối lượng nấm khô)

vậy khối lượng nấm khô thu được là:

   3÷3/5=5(kg)

a: Xét ΔMIN vuông tại I và ΔMIP vuông tại I có

MN=MP

MI chung

Do đó: ΔMIN=ΔMIP

b: Xét ΔMKI vuông tại K và ΔMEI vuông tại E có

MI chung

\(\widehat{KMI}=\widehat{EMI}\)

Do đó: ΔMKI=ΔMEI

Suy ra: MK=ME

c: Xét ΔMNP có MK/MN=ME/MP

nên KE//NP

a) Xét ΔMIN vuông tại I và ΔMIP vuông tại I có

MN=MP

MI chung

Do đó: ΔMIN=ΔMIP

b) Xét ΔMKI vuông tại K và ΔMEI vuông tại E có

MI chung

ˆKMI=ˆEMIKMI^=EMI^

Do đó: ΔMKI=ΔMEI

Suy ra: MK=ME

c) Xét ΔMNP có MK/MN=ME/MP

nên KE//NP

a) Xét ΔMIN vuông tại I và ΔMIP vuông tại I có

MN=MP

MI chung

Do đó: ΔMIN=ΔMIP

b) Xét ΔMKI vuông tại K và ΔMEI vuông tại E có

MI chung

góc KMI = góc EMI

Do đó: ΔMKI=ΔMEI

Suy ra: MK=ME

c) Xét ΔMNP có MK/MN=ME/MP

nên KE//NP
