Số viên đạn vận động viên bắn trúng đích là :
440 : 10 = 44 ( viên )
Đ/s : 44 viên đạn
Vận động viên đó bắn được số viên trúng đích là:
440:10=44( viên đạn )
Đáp số: 44 viên đạn
Mik khẳng định ko phải trúng 44 viên vì trượt 6 viên nên bị trừ 30 điểm nữa
Vận động viên đó bắn được số viên trúng đích là
440 : 10 = 44 ( viên )
đáp số : 44 viên đạn
Mỗi viên trúng đích và trượt sẽ lệch nhau 10 + 5 = 15 (điểm)
Giả sử tất cả 50 viên đều trúng đích thì số điểm là:
10 x 50 = 500 (điểm)
Số điểm nhiều hơn:
500 – 440 = 60 (điểm)
Số viên bắt trượt là:
60 : 15 = 4 (viên)
Số viên trúng đích là:
50 – 4 = 46 (viên)
Đáp số: 46 viên
Mik khẳng định
Giả sử nếu người đó bắn trúng hết thì người đó có:
50*10=500(điểm)
Người đó bị trừ:
500-440=60(điểm)
Vậy số viên đạn bắn trượt:
60:5=12(viên)
Số viên đạn bắn trúng:
50-12=38(viên)
Số viên bắn trúng đích là
440:10=44(viên)
Đáp số .....
Vận động viên đó bắn trúng đích số viên đạn là:
440 : 10 = 44 ( viên )
Đ/s: 44 viên đạn
Số viên bắn trúng đích là :
440 : 10 = 44 ( viên )
Đáp số : 44 viên
Số viên bi băn trúng đích là:
440:10=44(viên)
Đáp số:44 viên
Nếu bắn hết trúng 50 viên đạn vận động viên sẽ được 500 điểm.Vậy thì số điểm mà vận động viên đã bị trừ khi bắn trật là:500-440=60 điểm .Vậy số viên đạn VĐV bắn trượt là:60:5=12 viên.Lấy 50 -12 ta sẽ được 38 viên VĐV bắn được.
Lý do mình ko đồng ý với cách giải của các bạn kia vì các bạn quên rằng khi bắn trượt sẽ bị trừ 5 điểm.Nếu như các bạn đã nói bắn được 40 viên thì còn 10 viên bắn trật sẽ bị trừ tất cả là 50 điểm à!

bọn nào ra 44 viên đạn là bọn uống máu lồn tinh khiết
bây nhìn nè
chất nhìn mà học hỏi ê
440 :10 = 440:10
gâ cả
Mình khẳng định là 46 viên.
Thứ nhất: Các bạn ko dùng hết dữ liệu đề bài
Thứ hai: Các bạn làm ko đúng cách (đây là dạng toán giả thiết tạm)
Còn đây là bài của mình:
Mỗi viên trúng đích và trượt sẽ lệch nhau 10 + 5 = 15 (điểm)
Giả sử tất cả 50 viên đều trúng đích thì tổng số điểm là:
10 x 50 = 500 (điểm)
Số điểm giảm đi là:
500 – 440 = 60 (điểm)
Số viên bắt trượt là:
60 : 15 = 4 (viên)
Số viên trúng đích là:
50 – 4 = 46 (viên)
Đáp số: 46 viên
À mik nhầm, số tiền tăng lên nha
Giả sử 50 viên đều trượt đích thì số điểm đạt đc là:
5 x 50 = 250 ( điểm)
Số điểm thụt đi là:
440 - 250 = 190 ( điểm)
Số điểm thụt đi vì thay số điểm trúng đích bằng số điểm trượt đích.
Mỗi lần thay 1 điểm trúng đích bằng 1 điểm trượt đích thì số điểm thụt đi là:
10 - 5 = 5 ( điểm )
Số viên đạn trúng đích là :
190 : 5 =38 ( viên )
Đ/S: 38 viên đan
mình đồng ý với những bạn có kết quả là 46 viên,vì nếu bắn trượt thì 10 điểm đó cũng không được tính vào số điểm đạt được.Mấy bạn chưa sử dụng hết dữ liệu,với đây là dạng giả thiết tạm nữa
Giả sử 50 viên đạn đều bắn trúng đích.khi đó có tất cả số điểm là: 50*10=500 (điểm)Số điểm đã tăng lên là: 500-440=60(điểm)Số điểm đã tăng lên vì thay mỗi viên trượt bằng mỗi viên trúng.Mỗi lần thay 1 viên trượt bằng 1 viên trúng thì điểm tăng lên là: 10+5=15(điểm)Số viên bắn trượt là:60:15=4(viên) Số viên bắn trúng là:50-4=46(viên)
