Hi, can someone please help me?

Eddie

Step-by-step explanation:

Lynn finished her mile in 9 minutes. We can tell this as in the chart after 9 minutes, she had ran 1 mile. Eddie runs at a constant speed of 7.5 miles per hour, and we have to convert this to minutes per mile. To do this, we can divide the number of minutes in an hour (60), by 7.5. We can do this as every hour has 60 minutes, and we know Eddie can run 7.5 miles in those 60 minutes. When we divide 60 by 7.5, we are finding how long it takes in minutes to run one mile, for Eddie. When we do this we get 8, so Eddie is faster.

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
