Answer:
The correct option is (B).
Step-by-step explanation:
The length of the diagonal of a rectangle is inches.
Compute the value of inches as follows:
The number 181 is not a square of a whole number.
So, the square root of 181 must lie between two whole numbers.
Consider the following squares:
It is quite clear that the 181 lies between the square of 13 and 14.
So, it can be said that the square root of 181 is between the square of 13 and 14.
Thus, the length of the diagonal of a rectangle is between 13 and 14 inches.
The correct option is (B).
Answer:
The solution of the given equations
x =4 , y = 1
Step-by-step explanation:
<u>Explanation</u>:-
<u>Step(l</u>):-
Given the system of equations -5x+13y = -7 ..(l)
5x+4y=24 ..(ll)
<u>Step(ll)</u>
Adding (l) and (ll) equations and cancelling '5x' terms we get
13y+4y = -7 +24
17y = 17
dividing '17' on both sides, we get
y=1
<u>Step(lll):-</u>
Substitute y=1 in equation (l) , we get
-5x+13y = -7
-5x + 13(1) = -7
subtracting '13' on both sides, we get
-5x +13 -13= -7 -13
-5x = -20
Dividing '-5' on both sides, we get
x = 4
<u>Conclusion</u>:-
The solution of the given equations
x =4 , y = 1
