Bạn có câu hỏi nào liên quan tới Toán tiếng Anh thì lên mathu :))
Tìm 2 số biết tổng của chúng là 0,25 và tỉ số giữa chúng là 0,25
Ta có : 0,25 = 1/4
Số lớn :
0,25 : (4+1) x 4=0,2
Số bé :
0,25-0,2=0,05
Đáp số : 0,05;0,2
Change: 0,25 = \(\frac{1}{4}\)
Total numbers together are: 1 + 4 = 5 ( section )
The first number is: 0,25 : 5 x 1 = 0,05
The second number is: 0,25 - 0,05 = 0,2
Answer : ...
We have : 0,25 = \(\frac{1}{4}\)
We have diagrams :
The first number : |-----|
} 0,25
The second number :|-----|-----|-----|-----|
The first number is :
0,25 : ( 4 + 1 ) x 1 = 0,05
The second number is :
0,05 x 4 = 0,2
Answer : The second number : 0,2
The first number : 0,05
k me if I arm right , please
the ratio of two numbers is 3:5 and their sum is 104.
find their different
The smaller number is (Số bé là) : 104 : (3 + 5) x 3 = 39
The greater number is (Số lớn là) : 104 - 39 = 65
Their difference is (Hiệu 2 số là) : 65 - 39 = 26
(The ratio of two numbers is 3 : 5 and their sum is 104.Find their difference
= Tỉ lệ của 2 số là 3 : 5 và tổng của chúng là 104.Tìm hiệu của chúng)

Answer:
the ratio of three numbers is 2/5:3/4:1/6.Sum of squares of them is 24309.FInd the sum of them
Giải:
Gọi 3 số đó là a, b, c
Ta có: \(\frac{a}{\frac{2}{5}}=\frac{b}{\frac{3}{4}}=\frac{c}{\frac{1}{6}}\) và \(a^2+b^2+c^2=24309\)
Đặt \(\frac{a}{\frac{2}{5}}=\frac{b}{\frac{3}{4}}=\frac{c}{\frac{1}{6}}=k\Rightarrow\left\{\begin{matrix}a=\frac{2}{5}k\\b=\frac{3}{4}k\\c=\frac{1}{6}k\end{matrix}\right.\)
Mà \(a^2+b^2+c^2=24309\)
\(\Rightarrow\frac{4}{25}k^2+\frac{9}{16}k^2+\frac{1}{36}k^2=24309\)
\(\Rightarrow\frac{2701}{3600}k^2=24309\)
\(\Rightarrow k^2=32400\)
\(\Rightarrow\left\{\begin{matrix}k=180\\k=-180\end{matrix}\right.\)
+) \(k=180\Rightarrow a=72;b=135;c=30\)
\(\Rightarrow a+b+c=237\)
+) \(k=-180\Rightarrow a=-72;b=-135;c=-30\)
\(\Rightarrow a+b+c=-237\)
Vậy \(\left[\begin{matrix}a+b+c=237\\a+b+c=-237\end{matrix}\right.\)
