Peter is planting trees in his yard. He wants the ratio of pine trees to oak trees to be 3 to 2. Peter wants to plant a total of 45 trees. How many pine trees should he plant?

Step-by-step explanation:

Let the ratio of pine tree to oak tree=3x:2x

Where no. Of pine tree =3x

No. Of oak tree=2x

Total no. Of tree = 3x+2x=45

5x=45

X=9

So no. Of pine tree=3x=3x9=27 tree is answer

answer: the answer is 23

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
