Kayden has a job lifting really heavy rocks up four floors. Each floor is 3m high and he gets up by using a ladder. The strength he needs to lift each rock is 200 Newtons. Calculate the work he does when he lifts one rock up one floor.

Calculate the work Kayden does in an 8 hour day if he lifts 5 rocks up 4 floors in one hour.

Is Kayden getting any Mechanical advantage? Explain.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the answer is 8/21

hope this

i believe it's a.

i'm not sure on this one, most likely correct.
