21) A frozen yogurt store sells a small bowl of frozen yogurt for $2.50 plus $0.75 per topping. They sell a large bowl of frozen yogurt for $4.00 plus $0.50 per topping. For how many toppings will a small bowl of frozen yogurt cost the same as a large bowl of frozen yogurt? ​

Two toppings and a small bowl of frozen yogurt will cost the same as a large bowl of frozen yogurt.

Step-by-step explanation:

2.50 + .75x = 4.00

4.00 - 2.50 = 1.50

1.50/.75 = 2

2 toppings

i got 142 as my answer

step-by-step explanation:

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
