Answer:
1
Step-by-step explanation:
everything rise 0 power is 1.
So we have the equations:
y - 4x = 2 --- equation 1
5y - 2x = 1 --- equation 2
(equation 2) * 2
10y - 4x = 2 --- equation 3
(equation 2) - (equation 3)
-9y = 0 so y= 0 and thus x = -1/2

M = m /n
M molar mass
m mass
n number of moles
so n =m/M
n = 8.642/233.33=0.037mol

Answer:
Answer is 36cm
Step-by-step explanation:
Given:-
The perimeter of a square is 24 cm
To Find:-
It's Area
Solution:-
One side of the square
=24/4cm
=6cm
We know that, formula of the area of a square,
Area=(one side)^2
so,the area of the square=6^2cm=36
Important formula:-
•Perimeter of square=4×one side
•Perimeter of rectangle =2(length+breadth)
•Area of rectangle=length×breadth
I hope it's helpful!
"The exponential growth in popularity of administrative jobs among the Indian youth is clearly seen with the surging number of applicant appearing in UPSC IAS exam which is around 5 lakh every year and many more applicants trying their luck in the respective State PCS exams also.
