A= 1/1.2 + 

im ngạch xuất khẩu của Việt Nam với thị trường châu Âu là:

135,45-88,18=47,27(tỉ USD)

Kim ngạch xuất khẩu của Việt Nam với thị trường Mỹ là:

156,32%⋅47,27≃73,89(�ỉ���)156,32% . 47,27 = 73,89 ( tỉ USD )

Kim ngạch xuất khẩu của Việt nam với thị trường châu Á nhiều hơn tổng 2 thị trường kia là:

135,45-(47,27+73,89)≃=14,29(tỉ USD)

                                                  Đ/S: 14,29 tỉ USD.

a) Vì điểm C nằm giữa hai điểm A và B nên ta có:

         CA + CB= AB

          2,5 + CB= 5

                   CB= 5 - 2,5

                   CB= 2,5 cm
  Vậy CB= 2,5 cm

b) Mà CA= 2,5 cm

          CB= 2,5 cm

Suy ra: CA=CB

Mà điểm C nằm giữa hai điểm A và B .

Vậy điểm C là trung điểm của đoạn thẳng AB.

a) Môn học toán bạn Minh có điểm trung bình cao nhất học kì I.

b) Môn học toán của bạn Minh có tiến bộ nhiều nhất.

c) điểm trung bình cả năm của môn toán là:

       ( 7,9 + 2 . 8,6 ) : 3= 38,28

a) 3/4 + ( -1/3 ) + ( -5/18 )

= 9/12 + -4/12 + -5/18

= -5/12 + -5/18

= -15/36 + -10/36

= -25/36

b) 13,57 . 5,5 + 13,57 . 3,5 + 13,57

= 13,57 . 5,5 + 13,57 . 3,5 + 13,57 .1

= 13,57 . ( 5,5 + 3,5 + 1 )

=  13,57 . 10

= 135.7

Điện thoại của ông B không nhận được sóng wifi vì ông A cách bộ wifi 20m mà ông B  lại cách ông A 55 mét tức là ông B cách bộ wifi 75 m mà vùng phủ sóng wifi chỉ có 35m nên điện thoại ông B sẽ không nhận được wifi
