Subtract the measurements: 40 pecks 6 quarts − 20 pecks 7 quarts a.20 pecks 7 quarts b.20 pecks 4 quarts c.19 pecks 6 quarts d.19 pecks 7 quarts

Option D. 19 pecks and 7 quarts.

Step-by-step explanation:

Subtract the measurements : 40 pecks 6 quarts - 20 pecks 7 quarts.

There are 1 peck = 9 quarts

40 x 9 = 360  quarts

360 + 6 = 366 quarts

There are 1 peck = 9 quarts

20 x 9  = 180

180 + 7 = 187

366 - 187 = 179

179 quarts is your answer

Now convert it in to pecks and quarts divided by 9

179 ÷ 9 = 19.888 ≈ 19.9  19 pecks 9 quarts close to Option D.

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
