Let

x ----> total games played this season

we know that

12 games represent 60% of the games they have played this season

using proportion

Find out how many games represent a percentage of 100%

$\frac{12}{60\%}=\frac{x}{100\%}\\\\x=12(100)/60\\\\x=20\ games$

What steps do I take for this

Luden [163]

First, divide the shape into two figures ( a semicircle and a rectangle)
Then, find the are or the two shapes using the area formula for a semicircle ( $\frac{ \pi r^{2} }{2}$ ) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer

What is the vertex of the function f(x) = x2 + 12x?

Sophie [7]

We can start by figuring out the axis of symmetry.

y = x² + 12x = x (x + 12)

So roots are x = -12 or 0

Therefore axis of symmetry is x = (-12 + 0) / 2 = -6

We got x-coordinate of vertex. Now plug in x=-6 to solve for y.

y = (-6)² + 12(-6) = 36 - 72 = -36

Therefore vertex is (-6, -36).

Does anyone know how to do this?

Elanso [62]

Answer:

( n − 2 ) × 180

Step-by-step explanation:

The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

hope this helps :))
