Step-by-step explanation:
2/3 = 0.666666...
50% = 0.5
0.6666...>0.5
Therefore, 2/3>50%
Answer:
x = 4
Step-by-step explanation:
Given
= 
( cross- multiply )
4x - 7 = x + 5 ( subtract x from both sides )
3x - 7 = 5 ( add 7 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4

Option A) Center: (2,5) & Radius=7 is the correct one.
<u>Step-by-step explanation:</u>
The general form of the equation of the circle is given as :
⇒ (x-h)² + (y-k)² = r²
where,
- (h, k) are coordinates of the center point of the circle.
- r is the radius of the circle.
Therefore, you need to compare the given equation with the general equation of the circle.
The given equation of circle is (x-2)² + (y-5)² = 49
From the given equation, it can be determined that
h = 2 and y = 5 and r² = 49
The center (h,k) of the circle is (2,5).
<u>To find the radius r :</u>
⇒ r² = 49
⇒ r = 7
The radius of the circle is 7.
∴ Option A) Center: (2,5) & Radius=7 is the correct one.
Answer:
F.
Step-by-step explanation:
We are given a series
We can see that numerators are same
and denominators are
49 , 64 , 81 , .....
so,
7^2 , 8^2 , 9^2
We can write nth term
so, we can write as
We can use p-series test
we can compare
and we get
So, this series is convergent
this is FALSE
