a, thể tích bể bơi là:

40x20x3,5=2800(m3)

b, diện tích xung quanh là:

(40+20)x2x3,5=420(m2)

tổng diện tích xung quanh và đáy bể là:

(40x20)+420=1220(m2)

diện tích lát gạch là:

1220-(1220x20%)=976(m2)

c) đổi 976m2=9760000cm2

diện tích một viên gạch là:

10x10=100(cm2)

cần số viên gạch là:

9760000:100=17600 (viên gạch)

cần số hộp gạch là:

17600:10=1760 (hộp gạch)

chi phí lát gạch là:

510000x1760=897600000(đồng)

A = 1 + 3 + 32 + 33 +...+ 341

A = 30 + 31 + 32 + 33 +...+ 341

Xét dãy số: 0; 1; 2; 3;...;41

Dãy số trên là dãy số cách đều với khoảng cách là: 1 - 0 = 1

Dãy số trên có số số hạng là: (41 - 0): 1 + 1 = 42 (số hạng)

Vậy A có 42 hạng tử. Nhóm 3 hạng tử liên tiếp của A thành một nhóm thì vì 42: 3  = 14

Nên  A = (1 + 3 + 32) + (33 + 34 + 35) +...+ (339 + 340 + 341)

        A = (1 + 3 + 9) + 33.( 1 + 3 + 32) + ...+ 339.( 1 + 3 + 32)

      A =  13 + 33.13 +...+ 339. 13

     A =  13. ( 1 + 33 +... + 339)

     Vì 13 ⋮ 13 nên 13.( 1 + 33 + ... + 339) ⋮ 13

Để mắt thấy được ảnh của chân thì mép dưới của gương cách mặt đất một đoạn nhiều nhất là đoạn NK.

Xét \(\Delta B'BI\) có \(NK\) là đường trung bình nên:

\(NK=\dfrac{IB}{2}=\dfrac{BA-AI}{2}=\dfrac{150-10}{2}=\dfrac{140}{2}=70cm=0,7m\)

Như vậy, người đó soi gương có thể nhìn thấy \(\dfrac{0,7}{1,5}\approx47\%\) cơ thể.

Để người đó nhìn thấy toàn bộ cơ thể thì mép trên của gương cách cách mặt đất ít nhất là đoạn NK.

Xét \(\Delta AII'\) có \(MH\) là đường trung bình nên:

\(MH=\dfrac{AI}{2}=\dfrac{10}{2}=5cm=0,05m\)

Mà \(MK=MH+HK=MH+IB=0,05+1,4=1,45m\)

Chiều cao gương để thỏa mãn điều kiện trên:

\(MN=MK-NK=1,45-0,7=0,75m\)
