How many combinations?
3 flavors
5 toppings
whip or no whip cream

30

Step-by-step explanation:3 flavors and 5 toppings multiplied is 15, and whip or no whip is a extra 2 choices so 15x2=30

let's say you have 3 flavors

- chocolate

- vanilla

- strawberry

lets say you have 5 toppings

- nuts

- carmel

- chocolate chips

- strawberries

- sprinkles

now you have the choice of having whip cream or no whip cream.

so what you do is start with the flavor vholctae go to the topping nuts then whip cream. now do the same thing but with no whip cream.

do the same with each flavor and at the end you have 20 combinations.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

what is the question?
