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.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
