Maria charges $5 per hour for babysitting. she wants to calculate the total amount of money she will earn this week. what variable is needed to calculate her earnings?

a. h, the number of hours she babysits
b. c, the amount she charges per hour
c. k, the number of kids she babysits
d. d, the number of days per week she babysits

A (H) because to know how much money she will "earn" she has to count how MANY hours she has worked to know how much she will be earning

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
