A Web music store offers two versions of a popular song. The size of the standard Version is 2.9 megabytes (MB). The size of the high-quality version is 4.3 MB. Yesterday, there were 1220 downloads of the song for a total download size of 4070 MB. How many downloads of the high-quality version were there?

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

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
