If the distance around the earth means circumference, it is, 24,887.64.(not rounded.) C=pi D (pi=3.14 + d=diameter)
The expression can be solved by expanding the bracket and multiplying out the terms
Therefore, the expression can be simplified as;
Alternatively, using the theorem of difference of two squares, which is
Hence,
Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
Answer:
C
Step-by-step explanation:
It is C because the 2 is attached to the variable Y
Answer:
-6v < -3; v> -0.5
Step-by-step explanation:
We have to find a number let say x
Given that:
-6v < x ........... eq1
v> - 0.5 ........... eq2
By taking equation 1
-6v < x
Dividing both sides by -6
(inequality will be inverted because of negative sign)
-6/-6 v > x/-6
v > x/-6 .........eq3
Now comparing eq2 and eq3 we get:
x/-6 = -0.5
Multiplying both sides by -6
x = -0.5 * -6
x = -3
So it will give:
-6v < -3; v> -0.5
I hope it will help you!
