Shelly's plumber charges her $50 per hour plus a service call fee of $75. If she is going to create a function to represent this situation, what would be her input (independent variable)? a. Total cost

b. Joe the plumber

c.50

d.75

e. Time, in hours

E. Time, in hours

Step-by-step explanation:

given data

charges her $50 per hour]

plus a service call fee of $75.

we know that the total cost can be expressed as

y=75+50xthis is the function to represent the situation

where x is the number of hours worked

Hence the input independent variable is x, which is the time she can dedicate for the work

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
