His lunch was $20.90

Step-by-step explanation:

First you have to find out how much he spent which would be 3/4 of 80 which is 60.

Then multiply 8.2 by 3 to find how much he spent on games which is 24.6

Then add 24.6 and 14.50 to find out how much we know that he spent which is $39.10

Then take 60 and subtract 39.1 from it to get 20.9 which is how much his lunch was.

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
