How many different pizzas combinations can be created using three toppings when you have 10 to choose
from?

120 different combinations

Step-by-step explanation:

How complicate do you want it be? consider or not consider the repeat of topping or the order of toppings.

If not consider the order of topping and the topping can't be repeated than

C(₁₀ , ₃) = (10 x 9 x 8) / (3 x 2 x 1) = 120

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
