Answer:
Step-by-step explanation:
We need to simplify . First of we need to know what LCM is, it is the lowest common multiply of two terms or numbers but in this case we are simplifying an algebraic expression so it is terms. Also we need to remember that since we have numbers and letters we must extract the LCM first then do the division so,
12xy ÷ 4y² → First of all we can cancel out the 12 and 4 by 3 and 1
3xy ÷ y² → Then the top y can cancel out with y² so on the numerator there no 'y' and on the denominator there is 'y'
The final answer is
Answer:
<h3>The answer is option D.</h3>
Step-by-step explanation:
First we must first find the LCM
The LCM of x² + 3x + 2 and (x + 2)(x + 1 ) is
x² + 3x + 2
So we have

Answer: 94.8 % (approx)
Step-by-step explanation:
Let the total household in the U.S is x,
⇒ The total household who did not have a telephone in 1960 = 21.5 % of x
= 0.215 x
According to the question,
The total household who do not have a telephone in 1990 = 75.8 % less than the household in 1960 who did not have the cell phone,
= (100-75.8)% of 0.215x
= 24.2 % of 0.215x
= 0.05203x,
⇒ The household in 1990 who had a telephone = x - 0.05203x = 0.94797x
Hence, the percentage of household who has a telephone in 1990
=
=
⇒ Around 94.8% household had telephone in the US in 1990.
Answer:
Step-by-step explanation:
Here, The perpendicular bisectors of sides AC and BC of ΔABC intersect side AB at points P and Q respectively, and intersect each other in the exterior (outside) of
Let L is the mid point of side BC while M is the mid point of side AC.(mentioned on below figure).
Then, In triangles QBL and QLC,
QL=QL, ( reflexive)
BL=LC, ( by the property of mid points)
And, ( right angles)
Therefore , (SAS)
Thus, ( by CPCT)
But,
Thus,
Now, In ,
⇒=
Similarly,
Then ( by CPCT)
But,
Thus,
Now, In ,
⇒=
Again, In ,
⇒
