Geoff and max are college roommates. geoff can clean their apartment in 2.5 hours and max can clean their apartment in 3.25 hours. how long will it take max and geoff to clean their apartment together?

1.41 hours

Step-by-step explanation:

Geoff: 2.5 hours = 1 job

Max: 3.25 hours = 1 job

Together:

            ⇒

            ⇒ 3.25x + 2.5x = 8.125

            ⇒             5.75x = 8.125

                           ÷5.75     ÷5.75

                                   x = 1.413

∠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.
