Bài 1: 

Ta có số tiền tủ lạnh sau khi giảm lần 1 là: \(15000000-15000000.20\%=12000000đ\)

Số tiền tủ lạnh sau khi giảm lần 2 là: \(12000000-12000000.5\%=11400000đ\)

Số tiền cửa hàng thu được sau khi bán 5 cái tủ lạnh: \(11400000.5=57000000đ\)

Lấy g = 10m/s² Lực Căng Của Dây Là: 241,9N

Gọi H là trung điểm của cạnh AB

\(AH=BH=\dfrac{AB}{2}=\dfrac{8}{2}=4\left(m\right)\)

Theo đề ta có OH =0,5 m

Xét ΔAHO vuông tại H

\(tan\widehat{AOH}=\dfrac{AH}{OH}=\dfrac{4}{0,5}=8\Rightarrow\widehat{AOH}\approx82^o\)

Ta có

\(T=\dfrac{P}{cos\widehat{AOH}}=\dfrac{mg}{cos\widehat{AOH}}=\dfrac{6\cdot10}{cos\left(82^o\right)}=431,11\left(N\right)\)

ta có:

\(\dfrac{P_1}{P}=\dfrac{S_1}{S}=\dfrac{\pi R^2}{\dfrac{4}{\pi R^2}}=\dfrac{1}{4}\)

\(\dfrac{P_2}{P}=\dfrac{S-2S_1}{S}=\dfrac{S-\dfrac{S}{2}}{S}=\dfrac{1}{2}\)

<=>\(\dfrac{P_1}{P_2}=\dfrac{1}{\dfrac{4}{\dfrac{1}{2}}}=\dfrac{1}{2}\)

ta tiếp có hệ pt:

\(\left\{{}\begin{matrix}\dfrac{OO_2}{OO_1}=\dfrac{P_1}{P_2}=\dfrac{1}{2}\\OO_2+OO_1=\dfrac{R}{2}\end{matrix}\right.\)

ra được :

\(OO_1=\dfrac{R}{3}\) và \(OO_2=\dfrac{R}{6}\)
