Answer:
Total number of ways will be 20
Step-by-step explanation:
We have given three identical green shirts and three identical red shirts
So total number of shirts = 3+3 = 5
We have to distribute these shirts to 6 children so that each children got one shirt
Number of ways will be equal to ( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )
y=
x+y=
Answer:
4
Step-by-step explanation:
Simplify x and y by rationalising the denominator of both
To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.
The conjugate of 2 + is 2 -
The conjugate of 2 - is 2 +
x = = = 2 -
y = = = 2 +
Thus
x + y = 2 - + 2 + = 4
The standard equation of a circle is expressed as:
Given a circle whose equation is
Get the centre of the circle
2gx = -2x
2g = -2
g = -1
Similarly, 2fy = 0
f = 0
Centre = (-(-1), 0) = (1, 0)
This shows that the center of the circle lies on the x-axis
r = radius = √g²+f²-C
radius = √1²+0²-(-8)
radius =√9 = 3 units
The radius of the circle is 3 units.
For the circle x² + y² = 9, the radius is expressed as:
r² = 9
r = 3 units
Hence the radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Answer:
Option 4 is correct that is both apply
Step-by-step explanation:
We have given the triangle we have to tell which postulate SSS or SAS to use to prove
ΔABC=ΔAED
We can use both of them
Case1: Since, three of the sides are equal that is
AB=AE
AC=AD
BC=ED
Which means SSS can be used
Since, SSS is side side side
Case2: Since one angle and two sides are equal
AB=AE
AC=AD
And ∠BAC=∠EAD
Which means SAS can be used
Since, SAS is side angle side
Therefore, Option 4 is correct that is both apply.
Answer: both apply
Step-by-step explanation:
SAS congruence postulate says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of other triangle then the two triangles are said to be congruent.
In the given triangles ΔABC and ΔAED , we have
∠BAC ≅ ∠EAD
AC ≅ AD
BE ≅ DE
If AB ≅ AE , then we have sufficient things to proof that ΔABC ≅ ΔAED by SSS congruence postulate .
i.e. for AC ≅ AD , BE ≅ DE and AB ≅ AE [all three sides are congruent]
ΔABC ≅ ΔAED by SSS congruence postulate.
Also, If AB ≅ AE , then we have sufficient things to proof that ΔABC ≅ ΔAED by SAS congruence postulate .
i.e. for AC ≅ AD [Side]
∠BAC ≅ ∠EAD [included angle]
AB ≅ AE [Side]
⇒ ΔABC ≅ ΔAED by SAS congruence postulate.
Hence, we can apply both postulates to prove triangles congruent .
BCredit unions limit membership to certain people or groups.
CCredit unions offer a wide variety of banking services.
DBoth A & B
Answer:
Both A and B are correct.
Step-by-step explanation:
The unique feature of credit unions is -
a)Credit unions are typically owned and run by their members
b)Credit unions limit membership to certain people or groups
Credit unions are non profit cooperative organisations whose members can borrow money from these institutions at low interest rates. This is run by a few members.
These provide a variety of financial services like- savings accounts, CD's, credit cards etc.
