Independent variable is basically x and dependent is y. Independent relies on itself and is always first while on the other hand dependent depends on the independent
Answer:
63 mm
Step-by-step explanation:
The formula to find the volume of a cylinder is V=h
You square the radius which would be 9
Then multiply that by 7 which is the height and get 63
Since it is left in terms of pi you do not need to multiply by pi so you add the pi symbol to the end.
Then get 63 mm
The approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4
<h3>Solving equations</h3>
From the question, we are to determine the approximate solution to the given equation,
The given equation is
First, add 8 to both sides
Now, divide both sides by 4
Take the exponents of both sides
x = 148.413
x ≅ 148.4
Hence, the approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4

Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150
