In a lab experiment, 70 bacteria are placed in a petri dish. the conditions are such that the number of bacteria is able to double every 28 hours. how many bacteria would there be after 4 hours, to the nearest whole number?

70 bacteria are placed in a Petri dish. the conditions are such that the number of bacteria is able to double every 28 hours.

after 28 hours the number of bacteria doubles so 70*2 = 140  bacteria

Now we make a proportion

x = 20

Number of bacteria is increased by 20

So 70+20 = 90 bacteria

90 bacteria would there be after 4 hours

∠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.
