The input distance of a screw is equal to the circumference of the screw multiplied by the number of times it is turned. If a screw with a circumference of 15mm is turned 5 times, so
that it penetrates into a piece of wood a distance of 10mm (output distance), what is the
screw's mechanical advantage?

step-by-step explanation:

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

let x be the amount she saves each month.

your final answer is x ≥

hope this !

the first one, all those points on the line just make a strait line.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
