Huang, josé, and sam ran a 100-m dash. josé did not come in second; huang did not come in third. josé’s time was 2 seconds faster than that of the oldest boy in the race. in what order did the boys finish the race? a. josé, huang, samb. josé, sam, huangc. sam, josé, huangd. sam, huang, josé

Option a. "José, Huang, Sam" is the order in which the boys finished the race.

Step-by-step explanation:

It is stated that José did not come in second, but that he was also 2 seconds faster than that of the oldest boy in the race. Although we do not know who is the oldest boy in the race, the fact that José was faster than him, and that he neither finished second, gives no other option than him finishing first. In addition it is stated that Huang did not come in third, therefore if José came in first, and Huang did not come in third, the only possible finish position is José first, Huang second, and Sam third.

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
