A box contained 125 screws. Mia used 1/5 of the screws on a woodworking project. She used 1/10 of the remaining screws on a different project. How many total screws did she use? PLZZZ HELP!!

the total number of screws used was (25) + (10), or 35.

Step-by-step explanation:

She used 1/5 of the screws, which comes to (1/5)(125 screws), up front:

(1/5)(125) = 25.

This left 100 screws.

She used 1/10 of these, or 10, screws on a different project.

Thus, the total number of screws used was (25) + (10), or 35.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
