Answer:
x = 10.5
Step-by-step explanation:
(r)=x .
y =18.8 / 2 = 9.4 .
z= 4.7
pythaoroas
r² = y²+z²
r²= (9.4)²+(4.7)²
r²= 88.36 + 22.09
√r² = √110.45
r = 10.5
Answer:
3 < c < 15
Step-by-step explanation:
If a triangle has sides a, b, and c, one of the following relationships must be true:
if a =9 and b=6, then:
Combining those inequalities gives us:
Therefore, the length of the third side could be any value between 3 and 15.
Answer:
Step-by-step explanation:
Consider the selling of the units positive earning and the purchasing of the units negative earning.
<h3>Case-1:</h3>- Mr. A purchases 4 units of Z and sells 3 units of X and 5 units of Y
- Mr.A earns Rs6000
So, the equation would be
- Mr. B purchases 3 units of Y and sells 2 units of X and 1 units of Z
- Mr B neither lose nor gain meaning he has made 0₹
hence,
- Mr. C purchases 1 units of X and sells 4 units of Y and 6 units of Z
- Mr.C earns 13000₹
therefore,
Thus our system of equations is
<u>Solving </u><u>the </u><u>system </u><u>of </u><u>equations</u><u>:</u>
we will consider elimination method to solve the system of equations. To do so ,separate the equation in two parts which yields:
Now solve the equation accordingly:
Solving the equation for x and y yields:
plug in the value of x and y into 2x - 3y + z = 0 and simplify to get z. hence,
Therefore,the prices of commodities X,Y,Z are respectively approximately 1477, 1464, 1437
